3 SAFETY NORMS AND LABELS 3.1 First aid for electric shock Do not touch the patient with bare hands until the circuit has been opened. Open the circuit by switching off the line switches. If that is not possible, protect yourself with dry material and free the patient from the conductor. ARTIFICIAL RESPIRATION It is important to start mouth to mouth resuscitation at once and seek doctor help immediately. TREATMENT OF BURNS This treatment should be used after the patient has regained consciousness. It can also be employed while the artificial respiration is being applied (in this case there should be at least two persons present). WARNING:

ED

•

Do not attempt to remove his clothing from the burnt parts;

•

Apply dry gauze on the burns;

•

Do not apply ointments or other oily substances.

02


13 / 24

1

Lay the patient supine with his arms parallel with the body, if the patient is laying on an inclined plane, make sure that his stomach is slightly lower than his chest. Open the patient’s mouth and check that there are no extraneous bodies in his mouth (dentures, chewing–gum etc.),

2

Kneel beside the patient level with his head. Put a hand under the patient’s head and one under his neck (see fig.) Lift the patient’s head and let it recline backwards as far as possible

3

Shift the hand from the patient’s neck to is chin: place your thumb between his chin and his mouth, the index along his jawbone, and keep the other fingers closed together (see fig.). While performing these operations take a good supply of oxygen by taking deep breaths with your mouth open.

4

With your thumb between the patient’s chin and mouth keep his lips together and blow into his nasal cavities (see fig.)

5

1AA 00014 0004 (9007) A4 – ALICE 04.10

6

ED

02


Mouth to mouth resuscitation method

While performing these operations observe if the patient’s chest rises (see fig.) If not it is possible that his nose is blocked: in that case open the patient’s mouth as much as possible by pressing on his chin with your hand, place your lips around his mouth and blow into his oral cavity. Observe if the patient’s chest heaves. This second method can be used instead of the first even when the patient’s nose is kept closed by pressing the nostrils together using the hand you were holding his head with. The patient’s head must be kept sloping backwards as much as possible. Start with ten rapid expirations, hence continue at a rate of twelve/fifteen expirations per minute. Go on like this until the patient has regained consciousness, or until a doctor has ascertained his death.

5 GENERAL ON ALCATEL CUSTOMER DOCUMENTATION 5.1 Products, product-releases, versions and Customer Documentation A ”product” is defined by the network hierarchical level where it can be inserted and by the whole of performance and services for which it is meant. A ”product” evolves through successive ”product-releases” which are the real products marketed for their delivery at a certain ”product-release” availability date. So, a ”product–release” defines a set of hardware components and a software package which, as a whole, identify the possible network applications and the equipment performance which the specific ”product-release” has been designed, engineered and marketed for. In some cases a ”product-release” has further development steps, named ”versions”, that are born to improve or add some performance (mainly software) with respect to the previous version, or for bug fixing purposes. A ”product-release” has its own standard Customer Documentation, composed by one or more handbooks. A new ”version” of a ”product-release” may or may not produce a change in the status of the Customer Documentation set, as described in para.5.4 on page 22.

5.2 Handbook supply to Customers Handbooks are not automatically delivered together with the equipment they refer to. The number of handbooks per type to be supplied must be decided at contract level.

5.3 Aims of standard Customer Documentation Standard Customer Documentation, referred to hereafter, must be always meant as plant-independent. Plant-dependent documentation, if envisaged by the contract, is subjected to commercial criteria as far as contents, formats and supply conditions are concerned (plant-dependent documentation is not described here). Standard hardware and software documentation is meant to give the Customer personnel the possibility and the information necessary for installing, commissioning, operating and maintaining the equipment according to Alcatel–Telecom Laboratory design choices. In particular the contents of the handbooks associated to the software applications focus on the explanation of the man-machine interface and of the operating procedures allowed by it.

1AA 00014 0004 (9007) A4 – ALICE 04.10

Consequently, no supply to the Customers of design documentation (like software source programs, programming tools, etc.) is envisaged.

ED

21 / 24

The handbooks associated to the ”product–release” are listed in para.2 on page 7. Each handbook is identified by: – the name of the ”product-release” (and ”version” when the handbook is applicable to the versions starting from it, but not to the previous ones), – the handbook name, – the handbook P/N, – the handbook edition (usually first edition=01), – the handbook issue date. The date on the handbook does not refer to the date of print but to the date on which the handbook source file has been completed and released for the production. 5.4.1 Changes introduced in the same product-release (same handbook P/N) The edition and date of issue might change on future handbook versions for the following reasons: –

only the date changes (pointed out in the Table of Contents) when modifications are made to the editorial system not changing the technical contents of the handbook.

–

the edition, hence the date, is changed because modifications made concern technical contents. In this case: • the table in para.1.4 on page 5 indicates the section(s) edition change; • in each section, the main changes with respect to the previous edition are listed; • in affected chapters of each section, revision bars on the left of the page indicate modifications in text and drawings (this is done after the first officially released and validated version).

Changes concerning the technical contents of the handbook cause the edition number increase (e.g. from Ed.01 to Ed.02). Slight changes (e.g. for corrections) maintain the same edition but with the addition of a version character (e.g. from Ed.02 to Ed.02A). NOTES FOR HANDBOOKS RELEVANT TO SOFTWARE APPLICATIONS

Handbooks relevant to software applications (typically the Operator’s Handbooks) are not modified unless the new software ”version” distributed to Customers implies man–machine interface changes or in case of slight modifications not affecting the understanding of the explained procedures. Moreover, should the screen prints included in the handbook contain the product-release’s ”version” marking, they are not replaced in the handbooks related to a subsequent version, if the screen contents are unchanged. 5.4.2 Supplying updated handbooks to Customers

1AA 00014 0004 (9007) A4 – ALICE 04.10

Supplying updated handbooks to Customers who have already received previous issues is submitted to commercial criteria. By updated handbook delivery it is meant the supply of a complete copy of the handbook new issue (supplying errata–corrige sheets is not envisaged). 5.4.3 Changes due to a new product-release A new product-release changes the handbook P/N and the edition starts from 01. In this case the modified parts of the handbook are not listed.

5.4 Handbook Updating

5.5 Customer documentation supply on CD–ROM


In the following by ’CD–ROM’ it is meant ’Customer Documentation on CD–ROM’ 5.5.1 Contents, creation and production of a CD–ROM In most cases, a CD–ROM contains in read–only eletronic format the documentation of one product–release(–version) and for a certain language. In some other cases, the same CD–ROM can contain the documentation of different product–release(–version)s for a certain language. As a general rule: –

–

CD–ROMs for Network Management products do not contain: •

the Installation Guides

•

the documentation of system optional features that Customers could not buy from Alcatel together with the main applicative SW.

CD–ROMs for Network Elements products do not contain: •

the documentation of system optional features (e.g. System Installation Handbooks related to racks that Customers could not buy from Alcatel together with the main equipment).

A CD–ROM is obtained collecting various handbooks and documents in .pdf format. Bookmarks and hyperlinks make the navigation easier. No additional information is added to each handbook, so that the documentation present in the CD–ROMs is exactly the same the Customer would receive on paper. The files processed in this way are added to files/images for managing purpose and a master CD–ROM is recorded. Suitable checks are made in order to have a virus–free product.

1AA 00014 0004 (9007) A4 – ALICE 04.10

After a complete functional check, the CD–ROM image is electronically transferred to the archive of the Production Department, so that the CD–ROM can be produced and delivered to Customers.

5.5.2 Use of the CD–ROM

The CD–ROM starts automatically with autorun and hyperlinks from the opened “Index” document permit to visualize the .pdf handbooks Other hyperlinks permit to get, from the Technical handbooks, the specific .pdf setting documents. In order to open the .pdf documents Adobe Acrobat Reader Version 4.0 (minimum) must have been installed on the platform. The CD–ROM doesn’t contain the Adobe Acrobat Reader program. The Customer is in charge of getting and installing it. ReadMe info is present on the CD–ROM to this purpose. Then the Customer is allowed to read the handbooks on the PC/WS screen, using the navigation and zooming tools included in the tool, and to print selected parts of the documentation through a local printer. 5.5.3 CD–ROM identification Each CD–ROM is identified: Each CD–ROM is identified: 1)

by the following external identifiers, that are printed on the CD–ROM upper surface: – the name of the ”product–release(s)” (and ”version” if applicable) – a writing indicating the language(s), – the CD–ROM P/N (Factory P/N and ANV P/N), – the CD–ROM edition (usually first edition=01)

2)

and, internally, by the list of the source handbooks and documents (P/Ns and editions) by whose collection and processing the CD–ROM itself has been created.

5.5.4 CD–ROM updating The list of source handbook/document P/Ns–editions indicated in previous para. 5.5.3 point 2 ) , in association with the CD–ROM’s own P/N–edition, is also loaded in the Alcatel–Information–System as a structured list. Whenever a new edition of any of such handbooks/documents is released in the Alcatel archive system, a check in the Alcatel–Information–System is made to identify the list of CD–ROMs that must be updated to include the new editions of these handbooks/documents. This causes the planning and creation of a new edition of the CD–ROM. Updating of CD–ROMs always follows, with a certain delay, the updating of the single handbooks composing the collection.

2 GENERAL DESCRIPTION OF THE CRAFT TERMINAL 2.1 Introduction The Craft Terminal is a project in charge of the local management of single network elements, providing ITU– compliant Information Model Interface to the Network Element. Multiple NE management up to 32 Network element is possible obtaining a remote Craft Terminal application. The general information of the Craft Terminal are presented in the Basic Craft Terminal Operator’s Handbook, that the operator have to read before this Handbook. In the Basic Craft Terminal Operator’s Handbook are described all the general description of use, login, navigation, rules, etc, common to all the NE using the same Craft Terminal. Further, the same handbook contains the detailed description of common operations as “Installation” and common screens as “Network Element Synthesis view”. The Network Element Synthesis view is the first view presented to the operator entering the application. Starting from this view it is possible login the NE and than enter the EML–USM views. This Operator’s Handbook deals with the EML–USM views of the Craft Terminal, which directly permit to manage the Network Element. The management main functions of the EML–USM are inserted at para. 2.3 on page 10. A detailed description of the EML–USM screens is given in Section Ne Management of this handbook. From the Craft Terminal is possible to run other Specific Software applications. These applications are in charge of the ISA–ATM, ISA–PR and ISA–PR_EA (Packet Ring Edge Aggregator) management inside the NE such as cross–connection, Backup and Restore configuration files etc. Details information about Specific Application are described in the relevant Operator’s Handbook (see Section 1 HANDBOOK GUIDE for the code). The list and part numbers of the SDH software products distributed by Alcatel is inserted in para.2.2 on page 6.

2.2.1 Software product and licences description The software products are distributed by Alcatel in a CD–ROM. In this CD–ROM are contained: •

Software packages for NE management by means of the craft terminal

•

Software package of the NE, to be installed in the NE or update the NE (by means of download function)

The software package used for management permits the dialogue between craft terminal and NE, to realize all the functions of the NES and EML–USM ). The software package used for updating the NE must be installed on the PC and then downloaded on the NE, thus following product evolution. Alcatel typically offers several software licences on the software product.

1AA 00014 0004 (9007) A4 – ALICE 04.10

They are referred both to the Network Element software features and to the Craft Terminal software features.

4 GLOSSARY OF TERMS Acknowledgment: When an alarm is taken into account by the application, the operator has to acknowledge it to point out that he has seen it and that he will react in the right way. During alarm configuration it is possible to set a maximum delay for alarm acknowledgement. The operator can decide whether or not the alarm clear has to be acknowledged. Administrator: A user who has access rights to all the Management Domains of the Craft Terminal product. He has access to the whole network and to all the management functionalities. Alarm: An alerting indication to a condition that may have an immediate or potentially negative impact on the state of an equipment or the CT. An alarm is characterized by an alarm begin and an alarm end. Alarm Severity Assignment Profile: Function allowing the assignment of severities to the alarms depending on their probable causes. Alarm Status: Identifies the type and severity of an occurring alarm. Board: A board is part of an NE. They are electronic cards that fit into slots in the NE. Bridge: The action of transmitting identical traffic on both the working and protection trails. Bridge Request: A message sent from a tail–end node to the head–end node requesting that the head–end perform a bridge of the working channels onto the protection channels. Bridge Request status: A message sent from a tail–end node to all other nodes within the protection system indicating that the tail–end has requested a bridge. Bridge&switch node: The node that performs the bridge and switch function for a protection event. Where the bridge and switch is performed on a per AU–4 basis, the node executing a bridge and switch of at least one AU–4 is referred to as a bridge and switch node. Note that with a Transoceanic application, a node in the switching status may not be a bridge&switch node, whereas a node in the pass–through state may be a bridge&switch node. With the Classic application, only a request node (see below) may be a bridge&switch node. Compact Disk Read Only Memory: Data saving support from which the information can only be read. Is useful for stocking data due to its available memory space.

1AA 00014 0004 (9007) A4 – ALICE 04.10

Equipment Protection Switching: Used to provide protection for cards within an equipment to protect traffic in the event of card failure. Extra traffic: Traffic that is carried over the protection trail when it is not used for the protection of working traffic. Extra traffic is not protected and is preempted when the protection trail is required to protect the working traffic. Filter: They are related to the alarms or events generated on an NE or internally within the OS itself. They can be configured by an operator to reject specified types of notifications and limit the processing that is applied to them. Flushing: This deals with logs.

To do this it uses a QB3* interface and performs the conversion QB3* ↔ QECC*. Head End: Node executing the bridge (adjacent along the direction where a failure is present) Human Machine Interface: It is the graphical user interface application through which the operators interact with the system. History Report: This function enables operators to get information concerning performances, security or alarms on entities composing the network, or on the network itself. The operator specifies the time period for which he requires the report. Idle: A node that is not generating, detecting or passing–through bridge requests or bridge request status information.

1AA 00014 0004 (9007) A4 – ALICE 04.10

Operator: The end–user of the Craft Terminal. He supervises a part of the network that is dependant on his user profile. Path: According to ITU–T Recommendation G.803, a path is a transport entity (i.e., architectural component) used to transfer information. Nevertheless, this name will be used throughout this document to indicate the information carried either unidirectionally or bidirectionally between two access points of a ring on either a path link connection (if the two points are both PDH) or trail segment. Physical Interface: Electrical or Electrical/Optical transformers that decouples the line signals and adapt the form of signal for further transmission. This functional block also manages clock extraction, signal loss monitoring and loopback functions. Port: A physical point at which the Network Element can be attached to a transmission medium. A port is either a termination point or an origination point. Protocol request: A message sent by a node to another node via K1/K2 bytes with the purpose of settling a certain behavior. All the K1 request codes represent protocol requests, but not all of them are bridge requests. For example, a SF–R is a bridge request (see ITU–T G841), but LP–S is not: both of them are protocol requests. Even NR is a protocol request. Protocol reply: A message sent by a node to another node via K1/K2 bytes with the purpose of acknowledging a received protocol request. Protection trail: The trail allocated to transport the working traffic during a switch event. When there is a switch event, traffic on the affected working trail is bridged onto the protection trail.

Span: The set of multiplex sections between two adjacent nodes on a ring. Span Switching: Protection mechanism similar to the MSP that applies only to four–fibre rings where working and protection channels are contained in separate fibres and the failure only affects the working channels. During a span switch, the working traffic is carried over the protection channel on the same span as failure. Squelched traffic: An all “1”s signal resulting from the squelching process (insertion of AU–AIS in order to guarantee the connections) Switch: The action of selecting traffic from the protection trail rather than the working trail. Switching Node: The node that performs the bridge or switch function for a protection event. In the case of a multiplex section switched ring network architecture, this node also performs any necessary squelching of misconnected traffic. Tail End: Node which detects the failure. Telecommunication Management Network: Defines the concept of interoperable management of TNs. They provide an organized network structure to achieve the interconnection of the different components of the TN and the services to process the information. Telecommunication Network: Describes the network to be managed. Provides the transmission, the transport and the switching supports to the interconnected Network Elements. Terminal Point: Describes either the origin or the termination of a signal in an equipment. Is related to a port. Thresholding: This is the assignment of a specified value to monitored parameters ( for example BIt Error Rates) that, when exceeded, generate trouble indications. Unprotected channels: See unprotected channel in ITU–T G841. Each pair of unprotected channels is made up on one in the working (semi)section plus one in the protection (semi)section.

1 INTRODUCTION 1.1 Scope 1.1.1 Document scope The aim of this document is to help the operator understand, configure and manipulate Network Elements (NEs) easily, using the Craft Terminal (CT). The different functionalities related to the equipment views, the menu items and the different actions that can be undertaken from these views are described in detail. Unless otherwise specified, the menu and the relevant description in the following chapters are intended as applicable to all the three Network Elements (1640FOX, 1650SMC, 1660SM). In many screen of this handbook the release number is not indicated, while it is instead present in the real screen displayed to the operator. This is due to the fact that the same screen is associated to the different releases. Sometimes the release number reported is only for example. The most part of the screen of this handbook are referred to 1660SM menu because it is the equipment with the complete set of features, so it has been choosed like reference example. Anyway similar screen are presented for 1650SMC and 1640FOX so can be apply to them, the same description of 1660SM . 1.1.2 Target audience This document is intended for the operators whose role is to manage the Network Elements.

2 GENERAL INTRODUCTION ON VIEWS AND MENUS


In this chapter the organization of the EML–USM screen, presented after the NE login, is described. First is introduced the view organization, than the accessible menu options are listed. At the end some further advice are given for Navigation principles.

2.1 EML–USM view organization The EML–USM view is the first window presented to the operator after the login. The first view is different according to the Equipment type but the navigation principles are the same for all; Figure 1. , Figure 2. , and Figure 3. show some examples. EML–USM view contains the following fields, that provide you with information needed to manage the NE: • • • • • •

Severity alarm synthesis, Domain alarm synthesis, Management status control panel View title, View area Message/state area

The Menu bar and the View area contained in the same NE view permits to performs all the configuration and supervision and display the specific selected item. The view organization is detailed in the Basic Craft Terminal Operator Handbook to which refer for the description, except for the following information, that differs according the NE type: –

2.3 Advices on Navigation principles

This general rules are described in the “Basic Craft Terminal Operator Handbook”. In this paragraphs are instead inserted menu options typical for every NEs involved in Navigation and example of Navigation. To reach a particular view of the NE there are several ways (navigation is also possible mixing the different ways): •

double click on the selected object

•

select the object and use the Open object or Open in Window option of the View pull down menu

•

use the Menu option tree structure. The View pull down menu permits to show the following menus: – – – –

Equipment Transmission Synchronization External Points

The menu structure permits to open the same window following several menu paths. EXAMPLE: to obtain the “Create Cross Connection” window: –

First navigation path: Open View – Transmission pull down menu Open Transmission – Cross Connection – Cross Connection Management pull down menu Select Create option in the presented window

–

Second navigation path: Open View – Equipment pull down menu Double click on Board body Select the Board to access the Board view Open Board – Port Access pull down menu Open Port – Cross Connection – Create Cross Connection pull down menu

–

Third navigation path: Open Configuration – Cross Connection Management pull down menu Select Create option in the presented window

The menu structure also permits to pass from a view menu to another (i.e. from “port view” to”board view” or to “transmission view”) thus facilitating the operators activity.

1AA 00014 0004 (9007) A4 – ALICE 04.10

Depending on which object the mouse arrow is located, a related pop–up menu can be activated by means of the right button of the mouse; this menu is correspondent to the possible actions that can be done on the specific object of the view.

Navigation rules are the same for all the NE using the same Craft Terminal Info Model.


Views Navigation The first level of the “Equipment view” representation will be displayed directly into the current window, immediately after the NE login. (See Figure 1. on page 18, Figure 2. on page 19 and Figure 3. on page 20). The Equipment view enables a fast navigation through all levels of the equipment hierarchy. Navigation is done from higher to lower levels. The NEs hierarchy is different organized according to the equipment type, as follow: –

1660SM & 1650SMC: Subrack > board > port > TP The navigation through different levels of the NE hierarchy is performed by double clicking on the objects (see also para 9.1, pg. 109): •

the first level shows the subrack level of the Equipment view (see Figure 2. on page 19 and Figure 3. on page 20); by double clicking on a board body , the board level of the Equipment view can be reached. further, by double clicking on a port body contained in the board, the port level of the Equipment view can be reached. The port view displays the inner TPs. it is possible to go back to the upper level of representation by pressing the key on the keyboard; It is also possible to: – go back to the previous view, by selecting the Backward option from the views menu – go to the next view, by selecting the Forward option from the view menu.

• • •

3 NE MANAGEMENT SUPERVISION

1AA 00014 0004 (9007) A4 – ALICE 04.10


This chapter is dedicated to the NE states and NE access.

3.1 NE management states The elementary building blocks of any telecommunication network are the Network Elements (NEs). Operating with the Craft Terminal the NE can present different management states according to the condition of the connection (supervision, local access, connection state, etc). Also general Alarm status are presented. Management states are present at Network Element Synthesis view level and at USM–EML view level. All the information referred to the management states are inserted in the Basic Craft Terminal Operator’s Handbook. Any disruption in the communication link between the CT and the NE results in an update of the management states when the CT has detected the communication failure.

ED

The Network Element Synthesis views enable you to get access to the current NE EML–USM view described in this handbook. The Network Element Synthesis views enable you to work on “local” or “remote” NE, selecting it and activating “Supervision” and “Show Equipment”, as described in the Basic Craft Terminal Operator’s Handbook. The EML–USM Main view is presented as for the following figures.

4 NE MANAGEMENT GENERAL CONFIGURATION In this chapter general configuration referred to the equipment management are described (Craft Terminal access, NE Time, Alarms configuration, etc).

4.1 Access state (allow or inhibit NE Craft access) The NE can be managed by the OS or by the Craft Terminal. To control the competition of the OS and the CT, a Local Access Control (LAC) is available. If the LAC is “granted” that means the CT is allowed to manage the NE. In the view the icon with a key symbol has a rectangular shape.

If the LAC is ”access denied” that means the OS manages the NE and the CT is not allowed to modify NE configuration (it can only “read”). In the view the icon with a key symbol has a circular shape.

If the LAC is ”requested” that means the CT has requested permission from the OS and is waiting for a replay. However the OS does continue to provide a certain number of services. These services includes: – – –

Reception and processing of alarms, Performance processing on TPs, Switching back to the OS access state.

The access state of an NE can be modified from two types of views: 4.1.1 Switching from the OS to the Craft Terminal access state Select the Supervision pull down menu. Then select the Requested option from the Access State cascading menu as shown in the following figure.

1AA 00014 0004 (9007) A4 – ALICE 04.10

Figure 14. NE management: setting the access state. From the confirmation dialogue box that opens you can confirm or cancel the ”Craft access” operation using the Yes or No push buttons. the request is up to the OS which accept or refuse it. If the OS doesn’t answer in a predefined time it is assumed that the NE is in the Craft access state and can be managed from a Craft Terminal.

ED

1AA 00014 0004 (9007) A4 – ALICE 04.10

Select the Supervision pull down menu. Then select the OS... option from the Access State cascading menu in Figure 14. From the confirmation dialogue box that opens you can confirm or cancel the ”OS access” operation. The NE is now managed by the OS. N.B.

The key symbol icon on the management states of the NE view, indicates whether the NE is managed by a Craft Terminal or by the OS.

N.B.

Local Craft Terminal access is denied on recovery phase after a loss of communication of the NE. When communication is lost with the NE, the OS automatically recovers the communication and put the state that was set before the loss of communication (therefore the Craft Terminal access can be denied or granted).

ED

4.1.2 Switching from the Craft Terminal access state back to the OS access state


4.2 NE Time management The NE local time of a selected NE can be visualized and/or re–aligned on the OS time basis. In this view the OS indication identifies the Craft Terminal. The status of the Network Time Protocol can be checked Select the NE Time... option from the Configuration pull down menu.

The following fields are available:

–

NTP Status section (read only) with the following parameters: •

NTP protocol It can be enabled (in the NTP Server Configuration option at para 8.5 on page 92) or disabled or empty (greyed).

•

NTP Main and NTP Spare It displays the status of the Main and Spare NTP: reachable or unreachable.

Time section with the following data: •

NE Time and OS Time It displays (read only) the time of the Network Element and of the OS (Craft Terminal).

•

Set NE Time With OS Time It permits to align the NE time with the time of the Craft Terminal.

Two different operative conditions can be defined: –

NTP protocol enabled In this case, NTP Main and NTP Spare will be reachable or unreachable. When both are reachable the NE uses the Main. The Set NE Time With OS Time message is not operative and the user cannot set manually the NE Time.

–

NTP protocol disabled In this case, the NTP Main and NTP Spare are empty (greyed); the Set NE Time With OS Time message is operative and the user can set manually the NE Time (i.e. change the NE time with the Time of the Craft Terminal).

If you do not want to set the NE local time, click on the Close push button to close the dialogue box. To re–align the NE time on the OS time basis click in the Set NE Time With OS Time radio button and either click on the Apply push button to validate or on the Close push button to cancel and close the dialogue box. The OS time comes from the PC date configuration which corresponds to the legal GMT time.

1AA 00014 0004 (9007) A4 – ALICE 04.10

N.B.

ED

When the NTP is not present, the OS system re–aligns the time of all supervised NEs periodically and automatically with a configured periodicity. This periodicity is common for all the NEs. If you set the NE time, you will force the change, with an immediate effect on the NE. However it will not have any effect on the periodic and automatic mechanism.

•

Profile “No Alarms” : (i.e. all alarms disabled). This ASAP inhibits the emission of any potential alarm.

•

Profile “10001” can be set by the user. Each single alarm can be classified with a criterion selected by the operator. A default standard configuration is set (Battery Degraded, Battery Failure, Communication Subsystem Failure, Path Trace Mismatch are not alarmed). NOTE: if this profile is not already present in the list, it is necessary to create it, by using the dialog of Figure 18. , selecting one existing profile and then clicking on the Clone button.

•

Another Profile #10002 can be created by the user, as explained for the #10001; the profile identifier is incremented automatically.

The Probable Cause Families check buttons allows to filter the probable causes that will appear in the Probable Cause Name list. NOTE: it is necessary to choose one or more of these filters to have the list. To find a particular probable cause, enter its name in the Search entry box at the bottom. ASAPs are already defined in the system with default values for the assigned severities. You can modify the severity associated with each probable cause. To do this, select the probable cause whose severity level you wish to modify. Then click on the option button: Service Affecting (not protected probable cause), and then Non Service Affecting (protected probable cause) and then Service Independent (don’t used, it is not operative). For each the severity can be chosen from ”Critical”, ”Major”, ”Minor”, ”Warning”, ”Non–alarmed” or “Not used”. A ”Non–alarmed” probable cause corresponds to no alarm emitted for this probable cause. When selecting Details the assigned severity are only shown and it isn’t possible to modify. When you have finished configuring ASAP, press the OK button to confirm the settings and close the dialogue box or the Cancel push button to cancel the new settings and close the dialogue box.

The number of severities and the number of probable causes is fixed. The ASAP function only enables the modification of the severities assigned to the probable causes, it does not allow the addition, removal or modification of these severities and causes.

N.B.

To take into account a profile modification, it is mandatory to perform a re–synchronization of the alarms (see para. 4.3.5 on page. 61). During this re–synchronization, the severity of each alarm is updated. Otherwise, the severities are updated only when the modified or new alarms are emitted by the NE.

6 EXTERNAL INPUT AND OUTPUT POINTS MANAGEMENT

1AA 00014 0004 (9007) A4 – ALICE 04.10


This chapter describes how to display and set the input/output environmental alarm (housekeeping alarm), An external input point is an environmental alarm (also called housekeeping alarm). It corresponds to an external event which is monitored by the NE. Number of relays on the NE are dedicated to check modification of the environment as for example a fire, a flood ... An external output point is used to manage a NE contact (i.e relay) connected to detector. An external output point is independent from external input point. The operations that can be undertaken in this section are: –

Displaying external points,

–

Expanding or reducing external points list,

–

Configuring input and output external points.

Note: the max. number of External Points depends by the equipment type (1640FOX, 1650SMC, 1660SM) and board type were applicable ( example CONGI 3 Wire or CONGI 2 Wire boards equipped in 1650SMC and 1660SM); for details refer to the relevant Technical Handbook.

8 COMMUNICATION AND ROUTING MANAGEMENT 8.1 Overview on Communication and Routing Domain The purpose of the communication and routing domain is to define configuration parameters concerning the communication protocols for the local NE, the OS and each other related NE in order to provide a global communication capabilities inside the network. 8.1.1 OSI Protocol on QB3/Qecc A brief description of basic concepts and terms involved in the communication and routing domain follows. During the TMN design process, a network is partitioned into domains; each domain can consist of a collection of two types of nodes: •

nodes supporting a link state routing protocol IS–IS; these nodes will be called adaptive routers; IS–IS protocol floods the network with link state information in order to build a complete consistent picture of the network topology. Use of IS–IS routing protocol in a TMN facilitates installation and operation due to the ”self learning” capabilities of these protocols and automatic network reconfiguration in case of failure; moreover the use of these standardized routing protocols guarantees interoperability in a multivendor environment. nodes not supporting these protocols; these nodes will be called static routers;

•

Networks partitions consisting of the former type of node will be called adaptive routing domains; networks partitions consisting of the later type of node will be called static routing domains. Moreover, a node which have to take routing decisions must became Intermediate Systems, all others can be made End Systems For the description of the following paragraphs use is made of Figure 45. on page 84. It is not a network planning example, it is only used to describe L1 ,L2, RAP and MESA. 8.1.1.1 OSI Partitioning into Routing Subdomains In order to reduce the overhead associated with distributed adaptive routing, it may be useful to divide a adaptive routing domain into smaller routing subdomains, called areas or level 1 subdomain. A level 1 subdomain should fulfill the following requirements: •

a level 1 subdomain should form a connected subnetwork; this subnetwork should have only a few links to the outside world, compared with the number of internal links; each node must belong to exactly one level 1 subdomain; each node which is connected to a foreign level 1 subdomain must become a level 2 intermediate system; level 1 intermediate systems know how to communicate only with IS in the same area; obviously, there must be at least one level 2 intermediate system per level 1 subdomain; Level 2 intermediate systems must form a connected network, because level 1 paths cannot be utilized for level 2 communication. This network will be called level 2 backbone.

• •

1AA 00014 0004 (9007) A4 – ALICE 04.10

•

In the most simple case, all nodes within a level 1 subdomain share the same area address. In general it is allowed to have multiple synonymous area addresses within a level 1 subdomain even if the usage of this features should be checked with Alcatel engineers. The synonymous list is used to ease partitioning in the future. There is a basic rule, which must be followed by two neighboring level 1 intermediate systems within a subdomain: there must be at least one area address in common between their two synonymous list, otherwise they are not able to communicate with each other.

ED

83 / 426

In certain situations it may be necessary to partition a given network into separate routing domains, where no routing information is exchanged between these domains. The major benefits of this partitioning are reduction of memory, processing and traffic overhead, because there is no exchange of routing information between the domains. Communication between separate routing domains must be achieved through the use of Reachable Address Prefixes (RAP). A Reachable Address Prefixes represents static routing information. It can only be associated with a link of a level 2 intermediate system, whereby this link crosses routing domain boundaries. A Reachable Address Prefixes is handled in the same way as information about a foreign level 1 subdomain within the own domain. The Reachable Address Prefixes indicates that any packet whose destination network address NSAP matches the prefix may be forwarded via the link with witch the prefix is associated. For example, consider network which is split into two separate routing domains: • routing domain A resides in a level 1 subdomain with area address ”a” • routing domain B resides in a level 1 subdomain with area address ”b” In order to enable the communication, the Reachable Address Prefixes in routing domain A must contain the area address ”b” and the Reachable Address Prefixes in routing domain B must contain the area address ”a”. On the other hand, within a given level 1 subdomain, there can be some NEs not supporting IS–IS nor ES–IS protocol (static routing). In such condition, the communication can be achieved through the use of Manual End System Adjacencies (MESA). A prerequisite for the use of manual end system adjacencies is that the area addresses of the connected nodes must be the same; as a consequence the nodes must belong to the same level 1 subdomain. Within a pure Alcatel network there is no need to use any kind of static routing. Therefore normally RAP and MESA shall never be used. AREA (subdomain) 1 L1

8.1.2 OSI Partitioning into separate Routing Domains


8.1.3 IP over OSI tunneling for ISA board This feature is applicable to NEs equipped with ISA boards (excepted ETHERNET and PR board) It permits to create a tunnel over OSI systems, to communicate IP management messages through an OSI network; it encapsulates the SNMP messages of the TCP/IP protocol stack over the OSI stack, using CLNP,LAPD,ECC protocols, and an OSI address. In this way the message reaches its final destination without repeated IP decapsulation/encapsulation in the intermediate nodes. 8.1.4 OSI over IP tunneling on QB3 This feature is not applicable to 1640FOX

This feature allows the Element Manager to reach the GNEs (and all the relevant NEs behind them) by using IP networking. This would permit to use an external DCN based on IP only. Hence, no OSI networking would be required on the external DCN. OSI over IP technique is used to meet the target. OSI packets leaving the SH are encapsulated into IP packets within the SH system itself. Hence, packets leaving the SH are IP packets, containing the original OSI packet. Once the packet get the NE through a pure IP network, the GNE has to strip off the IP encapsulation, extracting the OSI packet, and to route the OSI packet as it does today using a pure OSI networking. Hence, the internal networking of the SDH network (DCCs) is still based on OSI. No IP packets shall flow inside DCCs, because the GNE receives the IP packet containing the OSI packet, deletes the IP header, and forwards only the OSI packet on DCCs. The default OSI lower layers networking can be replaced by IP routing capability at the bottom of the QB3/QECC communication protocol suite; the choice is software switchable at NE level. The implementation adopts the RFC1006 standard to put the OSI upper layers on top of IP networking. The application goal is to offer the TCP/IP transport (i.e. Internet compatibility) in alternative to the full ISO/OSI communication protocols, in the complete DCN network or at least in a consistent portion of it.

8.3 Local Configuration Select the Configuration pull down menu. Select the Comm/Routing option and then from the cascading menu the Local Configuration option. The dialog–box opens (Figure 48. ) and allows to configure the local address of the NE. The following fields are present: –

a Local Address section contains the following graphical object: •

a Presentation Selector (P.Sel) identifies a presentation entity at the location identified by the NSAP Address. The presented value must not be modified.

•

a Section Selector (S. Selector) identifies a section entity at the location identified by the NSAP Address. The presented value must not be modified.

•

a Transport Selector (T. Sel) identifies a transport entity at the location identified by the NSAP Address. The presented value must not be modified.

•

a Network Service Access Point (NSAP) Address identifies a location in the network. The first field of the NSAP address, AFI, determines the NSAP format. The AFI filed is 2 characters long (2 exadecimal digits) and, depending on the its value, the length of NSAP address is variable from 16 characters to 40 characters: – the value of AFI 49 identifies the local format of variable length (from 16 characters to 40 characters). – the value of AFI 39 identifies the ISO–DCC format of 40 characters long. – the value of AFI 47 identifies the GOSIP–V2 format of 40 characters long. Field after AFI: (optional: if not used must be all–zero), area address and organization identifier. In all cases the last two fields of the NSAP address are: – System Id: uniquely identifies a NE in an area and is 12 characters long It might be the equipment MAC Ethernet address, level 2, inserted in the NE (check the value in the para. 8.7 on page 96 ) or it might be selected by the operator. – Network Selector: provides the distinction among users of the network service and is 2 characters long (value is “1d”).

1AA 00014 0004 (9007) A4 – ALICE 04.10

In the view, the NSAP is managed as simple strings of characters without any pre–formatting because of the variable format: – a first string of two characters that identifies the AFI field – a second string of variable length that identifies the remaining NSAP address –

Synonymous Area Addresses section allows to have multiple synonymous area addresses within a level 1 subdomain. The compilation of the two network addresses is optional and if they are inserted, the last two fields, System Id and Network Selector, of the mandatory address and of the synonymous addresses must be the same.

–

System Type section determines whether the local NE acts as a “intermediate system level 1” or as a “intermediate system level 2” or as a “End System”. Note that a level 2 intermediate system performs functions of a level 1 too. End System is not operative.

Destination NSAP Address:(OSI address of the NE ending the tunnel) a Network Service Access Point (NSAP) Address identifies a location in the network. The first field of the NSAP address, AFI, determines the NSAP format. The AFI filed is 2 characters long (2 exadecimal digits) and, depending on the its value, the length of NSAP address is variable from 16 characters to 40 characters: – the value of AFI 49 identifies the local format of variable length (from 16 characters to 40 characters). – the value of AFI 39 identifies the ISO–DCC format of 40 characters long. – the value of AFI 47 identifies the GOSIP–V2 format of 40 characters long. In all cases the last two fields of the NSAP address are: – System Id: uniquely identifies a NE in an area and is 12 characters long It might be the equipment MAC Ethernet address, level 2, inserted in the NE (check the value in the para. 8.7 on page 96 ) or it might be selected by the operator. – Network Selector: provides the distinction among users of the network service and is 2 characters long (value is “1d”). In the view, the NSAP is managed as simple strings of characters without any pre–formatting because of the variable format: – a first string of two characters that identifies the AFI field – a second string of variable length that identifies the remaining NSAP address

–

IP Routing:allows to choose the type of IP routing supported as follows; – OSPF (Open Shortest Path First) , if the “OSPF Area Configuration” option has been used (see para 8.12 page 102) – RIP (Routing Information Protocol) – Both – None, if the option “IP Static Routing Configuration” (see para 8.11 page 101) has been used If “OSPF” or “Both” options are selected, also the “Associated OSPF Area” must be set (it is to be chosen among the presented options); in this case the information field is automatically filled with the addresses set in the “OSPF Area Configuration” application.

In case of board containing “sub–boards”, another view permits to see the contained item, named “daughter” or “sub–board” (see example of Figure 80. ) An example of “daughter” with the presented port is in Figure 81. It is displayed after clicking on it. Alarms and Status indications referred to the board level are present at the bottom of the view, as indicated in the example (Administrative State and Board Alarms/Status). This information are “In/Out of service” of the board (Administrative State) and board alarms and status like “missing” (RUM) or “mismatch” (RUTM), EPS condition if supported and other indications typical of each unit . In the Maintenance section details on this indication are given.

11 PORT VIEW 11.1 Introduction This section describes the operations necessary for the consultation, modification and configuration of each port. The Port View permits to set and show the transmission resources (i.e. the Termination Point, TP) referred to the specific Port; it permits to check the detailed alarms presented by each TP of the Port, and the available menu permits to configure the port, (many setting options listed in the port menu are common with the “Transmission” view). In these views are presented only the TP specific of the port. The menu differs according the port type (SDH, PDH, HOA, ISA port). The Port View can be accessed from the Equipment or Transmission Views. The “Port view” is reached selecting the Equipment option in the View pull down menu then double clicking on the presented rack/subrack to present the subrack view, as described in chapter 9 on page 109. Double clicking on the selected board the relevant Board view is available presenting the ports (see chapter 10 on page 127). By double clicking on a board view, the corresponding port view is opened (see Figure 87. ). The “Port view” is also reached selecting the Transmission option in the View pull down menu. Then the Add TP option of the Transmission menu permits to select and confirm a TP (see the description at para. 14.5 on page 203). On the transmission view which appears select the TP and on the Transmission menu select the Navigate to a port view option. The HOA port view can be reached from the Port view, selecting a Tp and then Port –> Navigate to HOA port view. The ISA port (ATM, ETH, PR_EA) are not automatically created when the board is inserted in the subrack but must be created as explained in Chapter 20 on page 409. From the Port view It is possible to Navigate to Transmission view.

11.6.1 Automatic Laser Shutdown Configuration

Automatic laser shutdown (ALS) is useful in case of a loss of communication between two NEs due to optical fiber breakdown. For safety reasons it may be necessary to shutdown the laser to enable the fixing of the communication link. The automatic laser shutdown function can only be configured from the optical ports of the equipment. Select the SPI block in the port view and then select the Port pull down menu. Select the Physical media option and then from the cascading menu the ALS Management option .

1AA 00014 0004 (9007) A4 – ALICE 04.10

The Automatic Laser Shutdown State dialogue box opens ( Figure 97. ).

The aim of this paragraph is to describe the optical port hence the laser sources.


The dialogue box enables the ALS Management and the Restart parameters. The following actions are available: a)

Allow Automatic Laser Shutdown. To allow the automatic laser shutdown functionality, select the ALS Enabled option of the ALS Function: option button.

b)

Forcing the Laser to start or stop. When the laser is forced to ON or OFF, it is restarted or stopped and the Automatic Laser Shutdown is disabled, if it was not already so.

c)

1)

Force laser ON. To carry out a laser forced ON, select the Laser Forced ON option of the ALS Function then click on Apply and then or Close push button to close the dialogue.

2)

Force laser OFF. To carry out a laser forced OFF, select the Laser Forced OFF option of the ALS Function then click on Apply and then or Close push button to close the dialogue

Delete : this option deactivates the ALS function, returning to the state shown in Figure 98. on page 145. From this window it is only possible to create the ALS function (all the ALS commands are greyed).

1AA 00014 0004 (9007) A4 – ALICE 04.10

d)

Enabling or Disabling Automatic / Manual Laser Restart. To enable (disable) an automatic laser restart following an automatic laser shutdown (periodic restart), select the Enabled (Disabled) option of the ALS Auto Restart. The laser will be ON for 2 secs and OFF for 70 secs, in periodic mode. The same procedure is applicable for the ALS Manual restart : while the ALS auto Restart is disabled,the manual restart permits to perform a laser restart for a single time period.

ED

02


145 / 426

Wait to restart time The Wait To Restart Time: field indicating the delay period in seconds, occurring before an automatic laser restart is launched (following an automatic shutdown). The restart time period for this equipment is fixed to 70 secs.

f)

ALS Manual restart (not operative in current release) When the ALS Manual Restart is Enable it is possible to enter two different commands: Manual or Test Restart. The Manual command immediately activates a single laser restart: this command overrides the wait to restart time. The Test restart is similar to the manual restart but the laser remains “ON” for a longer time in order to make a measurement of the received optical power.

When all the different parameters have been configured, select the Apply button to confirm the setting and close the dialogue box. Selecting only the Close button allows you to cancel the choices made.

Note that the ALS procedure is activated ( if enable ) only when the fiber has been interrupted and the ALS state has not to be confused with the laser state. ALS states (see example of Figure 99. ), displayed by the functional state message area of the optical port, are: ALS states: Inactive = No ALS has been activated (Off) or the laser has been Forced ON/OFF. In test = The laser restart has been automatically activated . Active = The ALS has been activated (On). Undefined = The ALS is not present (not created). Laser state: On = all OK or ALS not present (not created). Off = Laser off (when ALS is created). Forced on = ALS forced on by operator command.

The single fiber configuration can be realized with passive optical couplers (see Figure 101. ) The optical coupler must not loop the Tx signal onto the local Rx . For this purpose and in general to avoid a low Tx/Rx decoupling also when the optical line is interrupted, an identification label has been assigned to the local Tx side ; the Rx part in the remote receive side checks the congruency between the received and the expected labels. If a signal label mismatch is recognized on the received section, an alarm (AIS and RDI) will be generated. Example of Figure 101. shows that is accepted the label “1” from Tx1 to Rx2 while is accepted label “2” from Tx2 to Rx1.

11.7 TP Frame Mode Configuration This menu item enables the configuration of the most important transmission parameters concerning the Primary Rate Access (PRA) and G.703/G.704 frame management. PRA management The PRA functionality performs termination bi–directional function for Time Slot 0 on framed with CRC–4 2 Mbit/s signal. In detail, it extracts in sink direction and writes in source direction particular bits (E, Sa5, Sa6 and A) of the Time Slot 0. Moreover, it generates substitution frames in case of detection of LOS on the signal coming from a Terminal Equipment. The PRA functionality has been extended in order to manage proprietary handling of the bits of Time Slot 0 (Framed with leased line PRA option) in terms of state, defect detection and consequent actions. G.703/G.704 management This functionality allows to activate the adaptation function to process a framed (G.704 interface) or not framed (G.703 interface) 2Mbit/s signal.

This TP Frame Mode Configuration option is available for: –

P12–CTP

Select the desired P12–CTP and then the Port –>TP Frame Mode Configuration option. TP Frame Mode Configuration can also be accessed from the “Transmission” and “Synchronization” view menu.

12 EQUIPMENT PROTECTION MANAGEMENT (EPS) This function is not applicable to 1640FOX ; the descriptions reported in this chapter is intended only for 1650SMC and 1660SM.

12.1 Introduction It is unthinkable to launch a telecommunications system, handling millions of communications, without the possibility of replacing equipment in a real time way, consequent to equipment failure. Everything must be done so that the communications can continue smoothly and so that the equipment failure remains transparent to the users. Protection management deals with this aspect of the EML–USM. The protection is performed by switching the board supporting the protected service when this board fails to a protecting board capable of supporting the same service. This protection is realized according to a protection scheme. An equipment protection scheme is composed of the following parameters which can be configured: •

Group type: 1+1 or 1+n the group type specifies if one or more unreliable resources for protection can be assigned to one or more reliables resources. 1+1 group type means that a working element is protected by one protecting unit. 1+n group type means that n working elements are protected by only one protecting unit.

•

Protection priority: A priority can be assigned to protected units in 1+n protection schemes. This priority can be be 1, 2, ... or n, 1 being the highest priority.

•

Configuration type: revertive or non revertive In revertive mode, a protected service will be switched back to its protected element when it has recovered from its failure. In non revertive mode, the switch to the protecting element is maintained even after a recovery from failure.

•

Protection wait to restore time: Used when revertive mode is active, the protection wait to restore time prevents several protection switches due to an intermittent failure. A protected element must be fault free during this fixed period of time before a protected service is switched back to it.

Board duplication remains the easiest way to ensure equipment protection in a system. The actions that can be undertaken are of the following type: – –

Consult and modify an Equipment Protection Scheme (EPS), Force Switch EPS,

In Board view, the board whose contents is represented is considered as implicitly selected.

13 MULTIPLEX SECTION PROTECTION MANAGEMENT (MSP) 13.1 Architecture types The Multiplex Section Protection (MSP, formerly called APS: Automatic Switching Protection) is the connection between two NEs protected by a cable and port duplication. At the source the signal is duplicated and sent to the sink via two independent cables. When occurs a multiplex section failure, the system switches to the other cable and port. The MS Linear Trail Protection can be applied to any NE where it is possible to configure a linear APS (single ended/dual ended) line protection. For this NE is applicable the APS 1+1 Proprietary, the APS 1+1 Standard and the APS 1 :1 Standard dual ended. The APS 1 +1 (not revertive) feature permits a 1+1 protection in a linear link, where a path signal is protected by another dedicated path carrying the same signal. The protection can be set both in single (unidirectional) and in dual (bidirectional) ended mode. In single ended mode (unidirectional) the protection is accomplished by switching only the signal affected by the failure. In dual ended mode (bidirectional) the protection is accomplished by switching both the affected and the unaffected signals . “Dual ended mode” (bidirectIonal) protection is not supported by 1640FOX and 1650SMC

Architecture 1+1 or N+1 Standard (the last is only available for 1660SM) Described in ITU–T Rec. G783/G841. The refence switching criteria are SF and SD. It provides a k1/k2 communication protocol thus this protection can be single or dual ended. Architecture 1+1 Proprietary (not used ) The refence switching criteria are SF and SD. No k1/k2 communication protocol is provided thus this protection can be only single ended. Architecture 1+1 Optimized (not used ) Architecture 1 : 1 Standard (not used ) Described in ITU–T Rec. G783/G841 as architecture 1 : n ( with n=1 ). The refence switching criteria are SF and SD. It provides revertive mode managed by k1/k2 protocol and thus this protection can be single or dual ended. The spare interface can be used to transport “low priority traffic” . The WTR time is used with revertive mode.

1AA 00014 0004 (9007) A4 – ALICE 04.10

Signal Degrade (SD) software setting enables the MSP protection mechanisms when a SD is recognized on the working port. The SD threshold reference value depend on the NE selected threshold on the MS termination point. This threshold value is configured as explained in the para.14.7 on page 217.

13.6 Display of Protection State The MSP protection state of a port is displayed at the bottom of the Port view. Some examples are reported in Figure 140. The following states are always displayed: Port Status – Active (red color) or Standby (orange color). The active protection status is referred to a protected/protecting port ( where the traffic is transported): when a failure is detected, the protecting port is ready to save the traffic (and becomes active). The standby protection status is referred to a protecting/protected port that is ready to save the traffic. MSP Protection Role – Protected (green color) or Protecting (ochre color). The protection role depends on the selected port type (Protected / Protecting). MSP Group Status, MSP Own Unit and MSP Related Unit – (green color) Displayed if an automatic switch is requested. “Own Unit” stands for the currently displayed unit in the port view, “Related Unit” stands for the related unit of the same protection group . The status indications are: NR: (abbreviation of No Request); normal, idle condition, the traffic is on the main port DNR:(abbreviation of Do Not Revert); the SF or SD have been recovered but the traffic is switched on the spare port PF: a protection failure has been detected on the port RF: a release command has been failed FOP: a failure of protocol has been detected complete: = the bridge/switch actions are completed pending: = the bridge/switch actions are pending The “complete” and “pending” indications precede the following statuses: AS: automatic protection switching enabled MS: a manual local protection command has been activated FS: a forced local protection command has been activated LO: a lockout local protection command has been activated SF/SD: Signal Failure or Signal Degraded has been detected WTR: wait time to restore status MSP Request Source – (green color) indicates where the operator commands (force/manual/lockout) have been performed. Only present when a command is operative. – Local: switch due to near end SD/SF or local user switch command – Remote: switch due to received K1/K2 bytes. A remote switch cannot be released locally, but can be overwritten by a switch with higher priority. MSP Protocol Status

13.7 MSP Commands Select the MSP Commands option from the Port –> MSP menu ( see Figure 141. on page 190 ) to open the “MSP Commands window” (see Figure 142. on page 191).

Figure 141. MSP Commands option Protecting Port : the location of the board hosting the protecting port is displayed. Protected Port : the location of the board hosting the protected port is displayed. The Lockout of protection command denies working channel access to the protection section by issuing a “Lockout” of protection request (on the “Protection Status” of MSP Management). It is possible to “Lockout the Protecting Port” or “Lockout the Protected Port”; to remove the lockout commands select Release Ping (for the protecting) and Release Ped (for the protected).

1AA 00014 0004 (9007) A4 – ALICE 04.10

The Force to command switches the working channel (Protected port) to the protection section (Protecting port), unless an equal or higher priority switch command is in effect or SF condition exits on the protection section, by issuing a “Forced” switch request for that port (on the “Protection Status” of MSP Management). It is also possible to switch back to the working channel using again the “Force to” Protected port command. For 1+1 non–revertive system, forced switch no working channel transfers the working channel back from protection to working section, unless an equal or higher priority request is in effect. Since forced switch has higher priority than SF or SD on working section, this command will be carried out regardless of the working section condition. The Manual to command switches the working channel (Protected port) to the protection section (Protecting port), unless a failure condition exits on the protection section or an equal or higher priority switch command is in effect, by issuing a “Manual” switch request for that port (on the “Protection Status” of MSP Management). It is also possible to switch back to the working channel using again the “Manual to” Protected port command. For 1+1 non–revertive system, manual switch no working channel transfers the working channel back from protection to working section, unless an equal or higher priority request is in effect. Since manual switch has lower priority than SF or SD on working section, this command will be carried out only if the working section is not in SF or SD condition

ED

190 / 426

The Clear WTR command cancel the delay time for switching protection and protecting port after recovery from failure/defect. The Exercise command issues an exercise request for protection channel and checks responses on MSP bytes, unless the protection channel is in use. This check controls the k1/k2 communication protocol functionality to be sure that the protocol is right also on the protection section. Not Operative in current release. The Release command clears all previously switching commands.

Figure 142. MSP Commands (example) The priority levels for the MSP commands are (from the higher to the lower one): Lockout, Force to, Auto–switch (SF&SD), Manual to. Table 3. on page 191 gives the priority rules when are occurred two different commands. The first column on the left and the first row at the top report the switch protection and the external MSP commands. The row/column crossing gives the command or protection result (i.e.: if an “Auto–switch” and a “Manual to” command are present, “Auto–switch” is operative.

14 TRANSMISSION VIEW 14.1 Overview This section describes the operations necessary for the consultation, modification and configuration of TPs, providing a representation of the entire signal flow. The generic Transmission View, described in this chapter, offers the possibility of displaying a single TP or a set of all kinds of TPs (or collected functionality which is represented by one/several TPs). To display the termination points in the Transmission View, either select specific TPs from a TP search dialog or access the view directly from another view, e.g. by navigating from the Port View. The Transmission View provides the following features: –

Brief overview regarding transmission resources. •

An overview concerning all TPs belonging to a port can be called in by activating the function to expand the selected TP. TP names are listed in an additional information area if the mouse pointer is positioned over it. The following states are indicated (see Figure 146. on page 198): – – – – –

•

1AA 00014 0004 (9007) A4 – ALICE 04.10

–

the alarm state is indicated by the alarm synthesis icon the cross-connection state is indicated by a cross whether a TP can be structured is indicated by a circle whether a TP is under Performance Monitoring indicated by a blue “P” letter whether a TP is involved in a loop action, it is indicated by a back–folded arrow

An overview concerning signal flow can be requested by a user action. The user can select a TP and apply the action Transmission –> Show Cross-connected TPs. The result is that the objects related to the TP are displayed and lines indicate the connections. Expanding and hiding TPs that are related to the currently selected TP (e.g. show all TPs that are above the TU-12 CTP) enables all related TPs to be added to the view, thus providing a representation of the entire signal flow.

Display of single or multiple termination points. •

Search for and select a termination point in a TP search dialog and display it in the Transmission View.

•

Pop-up the Transmission View from the board view. All TPs/compound TPs associated with the physical port are displayed (i.e. TPs down to AU-4).

–

Provide the functionality to create/show cross-connections.

–

Provide the functionality to create/show Multiplex Section Protection

–

Provide the functionality to create/show Loopback commands.

–

Provide the possibility of configuring a selected TP. This functionality is accessed by calling the configuration dialogs of the common Transmission/Port Views category.

–

Provide the possibility of showing a detailed view of a TP with alarms, navigating to the Port view.

14.3 View Layout The Transmission View is a main view. It provides views of specific areas, which display the transmission resources, and the specific Transmission View pulldown menu which provides the Transmission View operations. 14.3.1 View Description Figure 147. illustrates the Transmission View area. TPs that are received from the network element are displayed in the Transmission View with the respective TP and connection symbols described in Figure 146. The number of TPs presented initially depends on whether the Transmission View is popped up from a board view, whether a TP has been selected in another view or whether it is called without a selected TP. When the “Transmission view” is reached selecting the Transmission option in the View pull down menu in its initial state contains no objects.

It is possible both to expand a VC-4, thus displaying all underlying TPs, and to hide TPs which are of no interest. The objects initially displayed depend on the situation/definition. 14.3.3 Naming TPs The following rules are applied in order to identify the TPs displayed: –

the root node contains the full user label,

–

all child nodes contain a short label indicating the position inside the tree.

14.3.4 Dynamic View Behavior The following section describes the view states and provides a short description of events that affect the view. 14.3.4.1 Initial state of the view In its initial state, the Transmission View contains no objects when it is reached selecting the Transmission option in the View pull down). Objects can be searched for and displayed using the Add TP dialog. 14.3.4.2 Working state of the view In its working state, the Transmission View already contains objects. If the operator searches for and displays a TP using the TP Search dialog, the view is first initialized again and then the TP is displayed. The same applies in the case of navigation from another view to the Transmission View – the Transmission View is always initialized and the corresponding objects are then displayed in it. 14.3.4.3 Navigation to Transmission View from other views If the Transmission View is popped up from the Port View, only the selected TP is displayed. 14.3.4.4 Alarm notification Alarms concerning the TPs displayed are indicated graphically by the alarm synthesis icons of the TP objects. The TP objects are updated accordingly. 14.3.4.5 Object deletion

1AA 00014 0004 (9007) A4 – ALICE 04.10

All kinds of object deletion events related to TPs displayed are indicated by the TP objects. The graphical objects are removed accordingly from the Transmission View. Example: modification of the payload structure from 63 TU-12 to 3 TU-3.

By introducing the Synchronous Digital Hierarchy (SDH), a standardized transmission has been created, matching the European with the American standard. The SDH signal structure contains an extended overhead as well as a fixed pointer controlled assignment of the user signal elements, thus improving the possibilities of the network management. Signals of the Synchronous and Plesiochronous Digital Hierarchy (PDH) are packed by synchronous multiplexers into Virtual Containers (VC). The STM-1 signal structure is achieved by using the multiplex structure complying with ITU-T and ETSI, (see Figure 177. ). Each of the user channels (2 Mbit/s, 34 Mbit/s, 45 Mbit/s and 140 Mbit/s) is packed into a container synchronous to the STM-1 frame according to a predefined structure.

1AA 00014 0004 (9007) A4 – ALICE 04.10

To adjust the plesiochronous signals to the synchronous network clock, certain filling algorithms are available. Fix fill bits are inserted into synchronous signals. A byte column (9 Byte) as Path Overhead (POH) is added to the Container (C) generated. Path Overhead and Container together form the Virtual Container (VC). With the pointer pointing to the start of the VC, in respect of the STM-1 frame, an Administrative Unit (AU) or – if several Containers of a group are to be combined – a Tributary Unit (TU) is generated. Several TUs form a Tributary Unit Group (TUG) and TUGs again can be combined into a VC. The AU of the signal, together with the Section Overhead (SOH), finally make up the STM-1 frame.

15.1.3 Definition of Termination Points (TP)


When ports are depicted on the user interface, the following abbreviations are used. This section concerns the multiplex structure (see Figure 177. ) as well as on the information model of object-oriented programming which was used when forming the user interface. As a rule, a Termination Point (TP) is the starting and terminating point of a transmission segment. A distinction is made between the following types of TPs: –

CTP (Connection Termination Point) The CTP represents the termination of a connection. The transmission signal is ”terminated”, i.e., the received signal is monitored and the error signaling evaluated, while own-code signaling is inserted in the transmitted signal.

–

TTP (Trail Termination Point) The TTP represents the termination of a transmission segment. The signal is monitored and passed on after modification in one form or another.

Both TP types exist on the SDH level and the PDH level. –

CTPs on SDH level On SDH level (see Figure 179. ) a distinction is made between the following CTPs: •

AU-4 (Connection Termination Point) The AU-4 CTP represents both the creation and termination of an STM-1 connection. The High-order Connection Supervision (HCS) function is included.

•

TU-x (Connection Termination Point), i.e. TU-12 CTP, TU-2 CTP, TU-3 CTP. The TU-x CTP represents both the creation and termination of a VC-x connection. The Low-order Connection Supervision (LCS) function is included.

CTPs on PDH level On PDH level (see Figure 180. ), a distinction is made between the following CTPs: •

E4 (Connection Termination Point) The E4-CTP represents the non–intrusive monitoring of incoming 140 Mbit/s PPI.

•

S4 (Connection Termination Point) The S4-CTP represents the non–intrusive monitoring of outgoing 140 Mbit/s PPI .

MSP definition Transmit side, the MSNP (AU4–CTP) input enters two different MSNP/MSN (unProtected CTP) sources and then the MSN–TTP working and protection sources (to insert the K1–K2 bytes) are sent to the own SPI interfaces. Receive side, the working and protection MSN/MSNP outputs (AU4–CTP) enter in the switching selector. The MSNP–TTP terminates the selected signal and checks the SSF and the MSP protocol failure.

A cross-connection represents the logical connection between the input and output of the matrix, called the matrix port. The matrix only receives and transmits signals in GTI format. The Generic Transport Interface GTI, Alcatel’s standardized signal format for internal interfaces, is similar to the STM-1 format. The incoming signals are mapped or converted to GTI format on the plesiochronous and synchronous I/O boards. This frame is based on the STM-1 frame specified by ITU-T Recommendation G.707. It enables the transport of all signals in the US hierarchy and ETSI hierarchy levels 1 to 4 (1.5 Mbit/s to 140 Mbit/s) mapped to Virtual Containers (VCs) (see Figure 177. ). The VCs are sent from the I/O boards to both copies of the Matrix (A and B) via the GTI. The matrix performs the cross-connection on the VC-4, VC-3, VC-2 or VC-12 level and transfers the VCs to the relevant I/O boards via GTI. The configuration of both matrix copies is always identical. On the I/O boards, one GTI signal is selected from Copy A or Copy B, based on quality. The NE supports unidirectional, bidirectional and broadcast connections unprotected as well as protected. 15.1.5.1 Unidirectional Connection Information is transmitted exclusively from the input port to the output port (point-to-point); there is no routing in reverse direction.

15.1.5 Cross-Connection Types


15.1.5.3 Broadcast Connection (Multi-leg / Multipoint) In contrast to a cross-connection between just two points (point-to-point), one source and one sink, a broadcast connection consist of one source and several sinks, different ‘legs’ that share the same source TP.

Non-intrusive Monitoring Adding a protection leg to a unidirectional cross-connection offers the ability to perform non-intrusive monitoring on this cross-connection. No errors are introduced to the original cross-connection with applying or removing the protection leg.

15.1.6 Cross-Connection Protection

A unidirectional connection is routed from Input A to the Output (primary route). In the case of a failure, the system automatically switches to the protection path from protection Input B to the Output. This second connection is permanently kept in hot standby operation (see Figure 184. ).

15.1.6.1 Protected Unidirectional Connection


15.1.6.3 Protected Broadcast Connection The protected broadcast is realized as a set of independent, protected, unidirectional connections using the same pair of input termination points, as illustrated in Figure 186. Each protection can be forced, locked out or switched independently. Therefore, if a failure occurs at a certain input, it is possible that only some of the protections of the protected broadcast actually switch to the protection input.

Creation and modification of cross-connections are performed in the Main Cross-Connection dialog. The dialog can be accessed via the Transmission or Port view as for the following menus example or by using the Create or Modify buttons (chapter 15.3.3 on page 259) in the Cross-Connection Management dialog (see Figure 189. on page 256). The dialog box of Figure 194. on page 267 is presented ( “Main Cross Connection” view).

To prevent operation faults, the system is designed according to the following guidelines: –

All operations that may affect traffic must be confirmed. The subsystem provides a confirmation dialog box before the operation can be executed.

–

If the window displays an existing cross-connection, the OK button is insensitive when this cross-connection is assigned to NML or it is not assigned to the user profile.

–

If the window is used to create a new cross-connection, the system verifies that the relevant TPs can be used (not assigned to NML and assigned to the user profile) after the OK button is pressed. If a specified TP is not permitted, the corresponding message box appears.

15.4 Create/Modify Cross-Connections

15.4.1 Cross-Connection Parameters


The “Main Cross Connection” view of Figure 194. on page 267 permits to create the cross connections. A cross-connection is defined through a set of parameters which depend on the connection and protection type. Only those parameters which are permitted within the current context can be accessed. All others are disabled (faded gray). To create a cross-connection, one or more of those parameters must be defined according to the cross-connection type. Table 8. gives an overview about the optional and mandatory input parameters for the various cross-connection types. Activate the relevant entry boxes first of all by clicking on them with the mouse. Configurable Parameters –

Type Select the connection type: • Unidirectional • Bidirectional • Drop&Continue

–

D&C Topology Select the direction for Drop&Continue: • Normal • Inverse

–

Protection Define protection state: • Protected • Not Protected

–

Prot. Criteria (only available for protected connections) Clicking on the Prot. Criteria button, Figure 191. for the Protection Criteria dialog is opened, where the user can display and configure the SNCP Type Protection. No protection criteria for automatic protection switching can be configured.

1AA 00014 0004 (9007) A4 – ALICE 04.10

The following SNCP Type are available:

Figure 191. Protection Criteria –

Revertive (available only for protected connections) Select whether protection is to be revertive or not. In Revertive mode, a protected service is switched back to its initial, protected element when the fault has been eliminated. When Revertive mode is active, the Wait To Restore protection period prevents several protection switches being initiated as a result of an intermittent failure. The protected element must be error-free during this defined period of time before a protected service is switched back to it. In the current release the Wait To Restore time period is fixed to 5 minutes. In Non-revertive mode, switchover to the protecting element is maintained even after the fault has been eliminated.

–

HOT (available only for protected connections) To enter the Hold Off Time expressed in msec. with a range from 0 to 10.000. HOT is the time between declaration of Signal Degrade or Signal Fail, and the initialization of the protection switching algorithm.

–

Input To enter the input TP, click the relevant Choose button and select the TP in the TP Search dialog (see Figure 151. on page 204). Otherwise, select the input field and enter the name of the TP directly.

–

Prot. Input To enter the protecting TP, click the relevant Choose button and select the TP in the TP Search dialog. Otherwise, select the input field and enter the name of the TP directly.

–

Output It is possible to enter one or more output TPs. To enter one output TP, click the relevant Choose button and select the TP in the TP Search dialog. Otherwise, select the input field and enter the name of the TP directly. To enter more than one output TP and create a broadcast connection, proceed as described previously and press button Add afterwards. The previously chosen TP is then moved to the list box located below. Click the Choose button and select the next TP in the TP Search dialog. Otherwise, select the input field and enter the name of the TP directly. Repeat this procedure for each destination TP.

When modifying a cross-connection, note that some of the transformations involved may affect traffic (because the system may have to destroy and re-create the cross-connection to perform the necessary transformation). As mentioned at the beginning of this chapter, the user is required to confirm operations affecting traffic, i.e. a confirmation window warns the user. Within the Main Cross Connection dialog, modification of a cross-connection is restricted to the protection state and the parameters required by the protection. Refer to Table 9. for an overview of the accessible parameter when the protection state has been changed from “not protected” to “protected” and vice versa. For a description of the parameters, please refer to the previous para. 15.4.1 on page 261. To modify a cross connection select one from the connection list of Figure 190. on page 258. and then click on the Modify button. N.B.

After modification of a cross-connection, the cross-connection list in the Cross Connection Management dialog is not automatically updated. Use button Search in this dialog to update the list.

15.4.3 Modify a Cross-Connection

The following few facts should be taken into consideration when modifying connections.


–

Unprotect a protected cross-connection (see Figure 198. ): When a protected cross-connection is being unprotected (protection changed to “not protected”), the dialog displays the additional option button Unprotected. It offers the choice of whether to keep the protected input TP (Input) or the protecting input TP (Prot. Input) as the only signal source of the new unprotected cross-connection. Ensure that the active TP is selected (i.e. check the protection state in the Cross-Connection Management dialog). An example is in the following Figure 198. In addition, a question box appears, asking the user to confirm the unprotect action.

15.5 Activate/Deactivate/Delete Cross-Connections 15.5.1 Activate a Cross-Connection Not supported in current release. The Cross Connection Management dialog provides the possibility of displaying a selection of existing cross-connections (see Chapter 15.3 on page 254). The connection state (Act = A or D) is indicated in this connection list. To activate a cross-connection, select one from the connection list (see Figure 190. ) and then click on the Activate button to initiate the process. A confirmation box appears in which to confirm the state change request. The connection in the list is automatically updated to indicate the new connection state (Act = A). If the set of cross-connections selected from the list includes both activated and deactivated cross-connections, clicking the Activate button only initiates actions on the deactivated cross-connections which were selected. 15.5.2 Deactivate a Cross-Connection Not supported in current release. After creation, a cross-connection is automatically in an active state. To deactivate a cross-connection, select one from the connection list (see Figure 190. ) and then click on the Deactivate button to initiate the process. A confirmation box appears in which to confirm the state change request. The connection in the list is automatically updated to indicate the new connection state (Act = D). If the set of cross-connections selected from the list includes both activated and deactivated cross-connections, clicking the Deactivate button only initiates actions on the activated cross-connections which were selected. 15.5.3 Delete a Cross-Connection Only deactivated cross-connections should be deleted. However, deletion of active cross-connections is possible.

1AA 00014 0004 (9007) A4 – ALICE 04.10

NOTE: the “Delete cross–connection” action is not possible in the case that is still existing any operation/connection/termination on the underlying supported signals, such as: • Performance Monitoring on lower or higher TPs • POM / HPOM operations • Lower order Connections • Higher order Connections • Lower/Higher order Path Terminations • Loop–backs • LAN/LAPD (and any comm/routing channel) • Auxiliary channels Thus the deletion of every active operation/connection/termination is necessary, in the same order as above listed, before the deletion of a cross–connection. To delete a cross-connection, select the corresponding connection from the list and click on the Delete button. To prevent operation errors, the user must confirm the deletion request. The deleted cross-connection automatically disappears from the connection list when the operation is successful.

15.6.1 Split a Cross-Connection Precondition Only bidirectional cross-connections can be split. Split Select one or more bidirectional cross connections from the list in the Cross Connection Management dialog and press Split. The cross-connections are split without further confirmation from the user. The original cross connection(s) disappear from the list in the Cross Connection Management dialog after a successful action. The user has to press Search to see the new cross connections. Depending on the protection state of the original cross-connection, the split action has the following effect: a)

Unprotected Cross-Connection An unprotected bidirectional cross-connection is split into two unidirectional cross-connections with the input TP in one of them being the output in the other and vice versa (see Figure 200. ). The new cross connection has the same name and activation status as the old bidirectional one.

Protected Cross-Connection


Splitting a protected connection results in one protected unidirectional cross-connection and one broadcast with two legs. The input of the original cross-connection is one of the legs in the broadcast. The other leg in the broadcast is the protecting input. The input of the broadcast is the output of the original protected cross-connection.

15.6.2 Join Two Cross-Connections

Two cross-connections can be joined if they match the following characteristics: –

The connections are either 1)

both unprotected, unidirectional and the input is the output of the other one, or

2)

one of them is protected and unidirectional, and the other one a broadcast with two legs. Restriction: the input of the broadcast connection has to be the output of the protected connection and the legs of the broadcast match the input and the protection input of the unidirectional connection, also refer to Chapter Split a Cross-Connection, effect b).

–

Both cross-connections have the same connection state (activated or deactivated).

–

Both cross-connections have the operational state “enabled”, i.e. they are listed in black color in the Cross Connection Management dialog.

Join Select exactly two cross connections in the Cross Connection Management dialog and press the Join button. The cross-connections are joined without further confirmation from the user. The original cross connection(s) disappear from the list in the Cross Connection Management dialog after a successful action. Press Search to see the new cross-connections in the list. The result is either a bidirectional (case 1, see Figure 200. ) or a protected bidirectional (case 2, see Figure 201. ) cross-connection.

1AA 00014 0004 (9007) A4 – ALICE 04.10

If the original cross-connections have different names, the new name is a concatenation of the names of both of them.

Precondition


15.7 Protection Switching The Protection Actions dialog is displayed after clicking on the Protection button in the Cross Connection Management dialog (see Figure 190. ). Users can only switch protection on cross-connections belonging to them and not assigned to the NML. A second condition is that protection is enabled for the cross-connection concerned (protection parameter is set to “protected”). The three protection actions Force, Lock Out and Manual Switch belong to different levels, whereby Lock has the highest priority and Manual Switch the lowest. Note that a protection state can only be changed within the same or from a higher priority level, e.g. Force To Protecting can be reverted with Release but not with Manual Switch To Input.

Figure 202. Protection Actions Dialog The dialog window enables the user to perform protection- related operations on protected cross-connections. These are: –

Force to Input The cross-connection is switched to the protected input regardless of signal quality. Automatic protection is disabled.

–

Force to Protecting (Input) The cross-connection is switched to the protecting input regardless of signal quality. Automatic protection is disabled.

16 OVERHEAD MANAGEMENT 16.1 Introduction All the descriptions in the following paragraphs are applicable only to 1650SMC and 1660SM. The purpose of this set of dialogs is to handle the operations on the Overhead (OH) bytes of the NE. The possible operations are: •

Overhead cross–connection – – – –

Cross–connection between 2 or more OH bytes Termination of an OH byte onto an auxiliary port or vocal channel Total Pass–through of the MSOH bytes for some cards Definition of the Phone Parameters

There is a TP associated to every OH byte and to every auxiliary port, so TP could be used instead of OH bytes or auxiliary port, depending on the context.

Note for 1640FOX: Two bytes of the SDH Overhead frame are accessible for auxiliary purposes, in V11 and RS232 format; the dedicated bytes are fixed and belong to the STM1#1 or STM4#1 (the module inserted in the highest position of the CompactADM unit). The auxiliary services on STM1#2 or STM–4#2 are not available in current release, except just in case of 1+1 MSP STM–N line protection.

1AA 00014 0004 (9007) A4 – ALICE 04.10

These bytes are E1 (for V11 signal) and F1 (for RS232). The auxiliary signals are available, at the back–side connector, as soon as the CompactADM unit is inserted, without any software presetting.

16.2 OH Connection overview


Here are described the possible OH connections For OH Phone Parameters directly refer to the para 16.7 on page 295. –

OH Cross–connection

The operator has to be able to cross–connect 2 or more OH bytes on 2 different boards. The possible cross–connection types are: • unprotected bidirectional point to point The steps an operator has to do in order to perform the cross–connection are the following: • •

create the OH TPs involved in the operation create the OH cross–connection: – select type of cross–connection – select the input OH TP involved in the operation – select the output OH TP involved in the operation

After having deleted an OH cross–connection, the involved TPs have to be deleted. –

OH Termination

The operator has to be able to terminate one OH byte onto an auxiliary port or vocal channel. The steps an operator has to do in order to perform the OH bytes termination are the following: • create the OH TP involved in the operation • create the OH byte termination: – select the created OH TP – select the auxiliary port/vocal channel TP involved in the operation After having deleted an OH byte termination, the involved TP have to be deleted. –

Total MSOH Pass–through

For STM ports it make sense to allow the operator to perform a total pass–through of the MSOH bytes. A total msoh pass–through connection (connection between msPassThroughCTP points) is set–up only if no single msoh pass–through connection are set and if no single msoh cross–connection are set. If a total msoh pass–through connection is set, a single msoh pass–through connection or a single msoh cross–connection cannot be set. The steps an operator has to do in order to perform the total MSOH pass–through are the following: • create the msPassThroughCTP points involved in the operation • create the total MSOH pass–through: – select the input msPassThroughCTP point involved in the operation – select the output msPassThroughCTP point involved in the operation

1AA 00014 0004 (9007) A4 – ALICE 04.10

After having deleted a total MSOH pass–through, the involved msPassThroughCTP points have to be deleted.

For all details, navigation and sequences on these views refer to chapter 15 on page 237. There is one big difference between the OH TPs and the other kinds of TPs: the OH TPs have to be: • created ONLY BEFORE a cross–connection/termination operation involving them has been performed. • deleted AFTER a cross–connection/termination deleting involving them has been confirmed. The current implementation of the TP Search Dialog (TPSD) works only with created TPs. In the following a description of the main functions and commands is given, also to list the Supported and Not Supported operation. 16.4.1 Cross-Connection Management for OverHead dialog See Figure 207. on page 288 –

Supported operations •

Search cross connections/terminations according to one or more of the following filtering attributes: type, TPs . The operator can set the filtering criteria, can start the search and select one or more cross connections/terminations among those presented in a read–only list as a result of the search operation. For each crossconnection/termination matching the filtering criteria, the following information is shown: direction (bidirectional) and the input, output TPs involved;

After choosing one or more cross connections/terminations, this dialog allows to: •

Delete the selected xconnection/termination

Note: this dialog disappears only when the user explicitly clicks on the close button. Delete operations can be performed on several cross connections/termination at the same time. Modify operations can be performed only on single cross connections/terminations. The OH xconnections are automatically active at the moment of their creation. The operation buttons availability follows some rules: •

The Delete and Print buttons are enabled only if at least one item is selected from the list. A special dialog will ask the user for a confirmation. the create button is always enabled. It brings up the Main crossconnection Dialog.

•

When some operation may affect the existing traffic, the operator is warned about that, and a confirmation dialog must be answered to carry on/cancel the operation. The choices for this dialog are: yes/no for single items, yes to all/cancel for multiple items –

Not Supported operation

17 PERFORMANCE MONITORING 17.1 Introduction The Performance Monitoring domain on the NE covers the monitoring of counter values for trail termination points and connection termination points. Examples of these counters on the SDH PORT are Errored Seconds (ES) and Severely Errored Seconds (SES). The Performance Monitoring domain counts these errors during specified granularity periods (15 min, 24h) and stores the values in history data logs. For the purpose of quality supervision, the values of the error counters can be compared to user-defined threshold levels. If a counter value has crossed a threshold level, a notification (threshold crossing alarm) is issued. The principle performance management functions are: –

Configuration of the counting interval for each performance measurement point.

–

Collection of the performance data.

–

Configuration of the quality thresholds that generate alarms and log records when predefined values are exceeded.

1AA 00014 0004 (9007) A4 – ALICE 04.10

On the ETHERNET PORT a set of performance counters are foreseen, for QoS and maintenance purpose. By selecting the GMAU TP and subsequently the Transmission–>Performance menu, the following options are available: –

Configure Performance Monitoring.

–

Display Current Data.

–

17.2.2 Supported Performance Counters The NE uses performance counters to count transmission errors. A set of performance counters is provided according to the Termination Point (TP), where performance measurement occurs. The user can start performance monitoring on one or more subsets of counters for each TP; it is not possible to start individual performance counters. Near end performance monitoring events are: –

Background Block Error (BBE): A BBE counter measures the number of errored blocks which do not occur as part of an SES.

–

Errored Second (ES): A one second period with one or more errored blocks or with a defect.

–

Severely Errored Second (SES): A one second period which contains > 30% of errored blocks, or at least one Severely Disturbed Period (SDP). An SES is also counted as an ES.

–

Near End Unavailable Second (NEUAS): An Unavailable Second is a second which is part of the Unavailable Time.

1AA 00014 0004 (9007) A4 – ALICE 04.10

The corresponding Far End (FE) performance monitoring events are: –

Far End Background Block Error (FEBBE): A far end errored block which does not occur as part of an FESES.

–

Far End Errored Second (FEES): Identifies, at a terminal, a one second period with one or more errored blocks or with a defect which were received by the Far End Terminal.

–

Far End Severely Errored Second (FESES): Identifies, at a terminal, a one second period which contains > 30% of errored blocks, or at least one Severely Disturbed Period (SDP) which was received/detected by the Far End Terminal. An FESES is counted as an FEES.

ED

17.2 Performance Monitoring on SDH port


–

Far End Unavailable Second (FEUAS): An Unavailable Second is a second which is part of the Unavailable Time at the far end.

The Termination Point (TP) type determines which performance monitoring events can be counted: –

SDH TPs Both near end and far end counters are supported in receive direction of the signal for all SDH path layers and for the multiplex section layer. For the regenerator section, no far end information is transmitted and, therefore, only near end counting is supported.

–

PDH TPs Only near end counters are supported in receive direction for all PDH path layers.

Further definitions: –

Errored Block (EB): A block in which one or more bits associated with the block are erroneous.

–

Remote Error Indicator (REI) [formerly Far End Block Error (FEBE)] : Identifies, at a terminal, the count of errored blocks that were received by the far end terminal.

–

Remote Defect Indicator (RDI) [formerly Far End Receive Failure (FERF)]: indicates to a terminal that the far end terminal has detected an incoming failure.

–

Unavailable Time (UAT): A period of unavailable time begins at the onset of 10 consecutive SES events. These 10 seconds are considered to be part of unavailable time. A new period of available time begins at the onset of 10 consecutive non-SES events.

–

Pointer Justification Event (PJE): A PJE is an inversion of I– or D– bits of the pointer , together with an increment or decrement of the pointer value to signify a frequency justification.

–

Out of Frame Second (OFS) ): An OFS is defined as a second in which one or more out of frame events have occurred. This event is identified by the A1/A2 byte of the SDH Frame.

1AA 00014 0004 (9007) A4 – ALICE 04.10

The counting of OFS is only supported for the regenerator section termination. Please note that this counter is deprecated by ETSI and will be removed from international standards.

17.2.4 Bidirectional counting (24 h Bi) for QoS As specified in G.826, G.784 and ETSI 300417, the bidirectional PM collection for Quality of Service has been supported by combining the information on each direction of transport to assess a single unavailability state: the bidirectional path is in the unavailable state if either one or both directions are in the unavailable state. PM data are collected by a single UAS plus two sets of three event counters (BBE,ES,SES) for NE–PM and FE–PM respectively. When the path transports unidirectional payload just the four counters for the NE–PM are activated (BBE, ES, SES and UAS). Data collection is performed only on 24 hours registers and the NE maintains a buffer of two registers: the 24hours current registers and the historical one.

17.2.3 Far End (FE) and Near End (NE) Performance Counting


17.2.5 End to End (e–e 24h) Performance Counting VCn trails can be monitored in intermediate node through the activation of performance monitoring process on Monitoring function. As the trails are often responsible of the end–to–end customer service, the end to–end monitoring can be requested to provide monitoring for Quality of Service purposes and , in addition, for network Maintenance applications. If SNCP is configured the Quality of Service collection have to be enable in the monitoring functions after the matrix . End to end monitoring is achieved by activation of Performance monitoring on the two direction of path and using far–end primitives. This process can be unidirectional (for Monitoring) or bidirectional process (for QoS). In case of unidirectional process one direction can be monitored end to end and both 15minute and 24 h collection can be activated 15min./ 24H FE_BBE, FE–ES, FE–SES, FE–UAS on incoming or egress signal depending of the POM is enable. The TCA are also evaluated in both 15 minute and 24 H counters. The bidirectional process needs the presence on the two Monitoring functions in the two directions in one NE and among the two monitoring function a 24 hour collection can be activated with the collection of incFE_BBE, incFE–ES, IncFE–SES, UAS, eFE–BBE, eFE–es, eFE–SES. 17.2.6 Performance Monitoring on AU–PJE AU PJE (Administrative unit point justification event) is an optional parameters request in G.784. For AU PJE counters , the positive and negative PJE shall be counted separately on one selectable AU within an STM–N signal, after the AU has been resynchronized to the local clock. Refer to G.783. The number of positive and negative outgoing PJE per second are collected in 15 minutes and 24 H counters. A history of 16 x 15minutes counters and 2x 24H are stored in the NE for each AU selected.

1AA 00014 0004 (9007) A4 – ALICE 04.10

No Threshold crossing mechanism is supported on AU–PJE counters.

TCM allows monitoring within the operator domain. The quality within the operator’s own domain can be proven regardless of the received quality of the signal at the entry point of the network. At the input point the reference value is set to zero by using the TCM feature. Tandem Connection Monitoring is applicable to VC–4–nc (n=1, 4, 16, ...), VC–4, VC–3 and VC–12 layers. TCM provides: – – – – –

Incoming error count (IEC); TC_REI to indicate errored blocks within the TC to the far end; OEI to indicate errored blocks of the egressing VC–n; TC_API as access point identifier complying with generic 16–byte string format; TC_RDI indicating to the far end that defects have been detected within the TC at the near end TC sink;

17.2.8 Performance Monitoring on 2 Mbit/s ISDN–PRA The feature provides PM data collection at the 2 Mbit/s ISDN–PRA terminations. The performance monitoring capabilities (applied on p12Mon TP) support both the standard data collection modes: –

G. 826 bidirectional for QoS

–

M2120 unidirectional near–end / far–end for maintenance

17.2.9 Performance Data Collection Near end and far end performance monitoring events are counted over fixed monitoring periods of 15 minutes and 24 hours. The 24-hour monitoring periods start at 00 : 00 (UTC) and the 15-minute monitoring periods start at xx : 00, xx : 15, xx : 30 and xx : 45. Performance monitoring can be enabled and disabled at any time during a monitoring period. An entity of all near end or far end performance monitoring events is always counted, it is not possible to start individual performance counters (e.g. SES only). BBE, ES and SES counting is stopped during Unavailable Time. Event Counting The performance events (e.g. SES) are counted in a counter per event. These counters are called the current registers. At the end of the monitoring period, the contents of the current registers are transferred to the first of the recent registers, together with a time stamp to identify the period (including the day). Time stamping is performed using UTC (as for all alarms). After that, the current register is reset. It is also possible to reset an individual current register manually. Suspect Flag

1AA 00014 0004 (9007) A4 – ALICE 04.10

A suspect interval flag is set as an indication that the data of the corresponding register may be either incomplete or invalid.

17.2.7 Tandem Connection Termination (TCT) and Monitoring (TCM)


Zero Suppression Zero suppression is a basic mechanism to remove irrelevant PM information and to reduce the amount of PM reports in the system. A PM report is suppressed and hence no history record is created by the entity which is responsible for PM reporting when all of the following conditions are true for the monitoring period: – – –

an interval is error-free (all PM counter values are zero) PM was enabled during the entire monitoring interval (the elapsed time equals its nominal value, i.e. 900 for 15 min. and 86400 for 24 h) PM was running properly (the suspect interval flag is not set)

By default, zero suppression is active for all PM enabled TPs. The number of suppressed intervals is indicated. 17.2.10 Data Collection N.B.

PM data is not counted on boards that were plugged out at the moment of enabling data collection (see PM Configuration dialog). Nevertheless, PM data is counted on boards that were plugged in at the moment of enabling data collection, but were plugged out and back in some time during data collection.

Performance Monitoring can be started at any time. As soon as Performance Monitoring is started on the Craft Terminal, current PM data is collected on the I/O boards, incrementing the performance counters each time an error is detected. The performance data counted is evaluated every quarter of an hour or every 24 hours and stored there in a history record. When the user disables the monitoring of a TP within the first 10 minutes of a 15-minute period, it is possible that have still not been received the PM data of the previous monitoring interval. Since PM data is not stored after monitoring is disabled, the PM data of the previous interval is lost in this case. If equipment or line protection switching occurs during a counting interval, the NE does not provide complete performance measurement for the protected TPs. Only the period between the last switch and the end of the counting window is counted. The interval is marked for suspect data and the elapsed time indicates the length of the measured period. 17.2.11 Performance Monitoring History Performance Monitoring history data is necessary to assess the recent performance of transmission systems. Such information can be used to sectionalize faults and to locate the source of intermittent errors. History data, in the form of performance monitoring event counts, is stored in registers in the NE. All the history registers are time stamped. In compliance with ETSI and ITU-T standards, the history registers operate as follows:

1AA 00014 0004 (9007) A4 – ALICE 04.10

The history data is contained in a stack of registers. There are sixteen 15-minute period registers and one 24-hour period registers per monitored event. These registers are called the recent registers. At the end of each monitoring period, the contents of the current registers are moved to the first of the recent registers. When all recent registers are full, the oldest information is discarded.

For quality supervision purposes, the recorded errors through the performance counters can be compared to threshold levels. If a counter value has crossed a threshold level, a Threshold Crossing Alarm (TCA) is transmitted to the alarm manager. The threshold values are defined in threshold tables together with a severity and a flag indicating whether crossing this value should be notified by an alarm and logged or only stored in the current problem list. The user can modify and delete such tables. Different thresholds can be assigned for near end and far end and for granularity of 15 minutes and 24 hours. The TCA only reports the value of the counter which has crossed the threshold, it does not provide a complete set of all counters. Therefore, the user has to explicitly retrieve all current performance data after receiving the alarm. The user can retrieve this information from the Current Performance Management Data Dialog. Two thresholds mechanism are supported: –

For 24–hour (implicit clearance) monitoring periods, one threshold value is defined: if the event count reaches or exceeds the threshold value during the monitoring period, a TCA is generated. To clear a TCA, the alarm must be manually acknowledged by the user.

–

For 15–minute (explicit clearance) monitoring periods, two threshold values (set, reset) are defined: a TCA is generated during the monitoring period when the event count reaches or exceeds the set threshold value the first time. This TCA is automatically cleared by the system at the end of the following monitoring period in which the event count is less than or equal to the reset threshold value and there was neither an unavailable nor a suspect period during this monitoring period

The following limitations apply for explicit clearance: –

The value of the low threshold is fixed to “0” (only a single threshold is provided by a threshold table).

–

An SES threshold crossing is cleared at the end of the interval if no unavailability was detected and SES had not reached the low threshold (low threshold equal to 0).

–

Even in case of a suspect interval the TCA is cleared if no unavailability was detected and the low threshold had not been reached.

1AA 00014 0004 (9007) A4 – ALICE 04.10

Additionally an explicit clearance of TCAs for all granularity periods is executed if one of the following events occurs during the current interval: –

deletion of the current data instance (TP),

–

resetting of counters (only for 24 h),

–

increased thresholds (higher than current value of counters) (only for 24 h).

Incoming (network centric view): it refers to the direction starting from Ethernet domain toward SDH domain (see Figure 214. ). The traffic arrives to the board from an Ethernet link and goes out from an SDH link.

[2]

Outgoing (network centric view): it refers to the direction starting from SDH domain toward Ethernet domain (see Figure 214. ). The traffic arrives to the board from an SDH link and goes out from an Ethernet link.

17.3.1 Overview

They can be: –

Physical interface counters

–

aggregate counters

–

flow counters

At physical interface level, the working status of transceiver is controlled. At aggregate level, all Ethernet traffics passing through the same port can be viewed as an aggregate. At flow level, each single flow is managed. Besides this classification, some counters can be of Quality of Service, others only of maintenance.

Ethernet counters can be distinguished from different points of view as depicted in Figure 215.

17.3.2 Ethernet physical interface counters


Ethernet physical interface counters are used to test Ethernet interface working state. They are: –

Symbol Error : for an interface operating at 100Mb/s, the number of times there was as invalid data symbol when a valid carrier was present. For an interface operating in full–duplex mode at 1000 Mb/s, the number of times the receiving media is non–idle carrier event for a period of time equal or greater than minFrameSize, and during which there was at least one occurrence of an event that causes the PHY to indicate Data reception error on the GMII. The count represented by an instance of this object is incremented at most once per carrier event, even if multiple symbol errors occur during the carrier event. This count does not increment if a collision is present.

–

Media Available Exits : number of times that ifMauMediaAvailable for this MAU instance leaves the state available. Discontinuities in the value of this counter can occur at re–initialization of the management system, and at other times as indicated by the value of ifCounterDiscontinuityTime

–

Jabber State : number of times that mauJabberState for this MAU instance enters the state jabbering. This counter will always indicate zero for MAUs of type dot1MauTypeAUI and those of speeds above 10Mbps. Discontinuities in the value of this counter can occur at re–initialization of the management system, and at other times as indicated by the value ifCounterDiscontinuityTime.

–

False Carrier: number of false carrier events during IDLE in 100BASE–X and 1000BASE–X links. For all other MAU types, this counter will always indicate zero. This counter does not increment at the symbol rate. It can increment after a valid carrier completion at a maximum rate of once per 100 ms for 100BASE–X and once per 10µs for 1000BASE–X until the next CarrierEvent. Discontinuities in the value of this counter can occur at re–initialization of the management system, and at other times as indicated by the value of ifCounterDiscontinuityTime.

Aggregate counters count frames that pass through the same port. Single flows are hidden inside the aggregate. Aggregate counters are (refer to : –

TRCO (Total Received Correct Octets): total number of octets of Ethernet frames received correctly by the Virtual Ethernet Interface , including Ethernet header characters.

–

TRCF (Total Received Correct Frames): total number of Ethernet frames received correctly by the Virtual Ethernet Interface

–

TTO (Total Transmitted Octets): total number of octets of Ethernet frames transmitted out by the Virtual Ethernet Interface , including Ethernet header characters.

–

TTF (Total Transmitted Frames): total number of Ethernet frames transmitted out by the Virtual Ethernet Interface

–

TDF (Total Discarded Frames): total number of Ethernet frames which were chosen to be discarded due to buffer congestion. – TRSEF (Total Received Service Errored frames): it is the sum of three contributions.

They are Quality of Service counters.

17.4 Configuration (SDH port)

Select the TP and open the PM Configuration dialog (see Figure 217. ) by clicking on the menu item Transmission –>Performance –>Configure Performance Monitoring.

This “PM Configuration” dialog serves as the main interface to all PM services. Every configuration of all monitoring intervals is defined using this dialog. It is possible to access the same “PM Configuration” dialog selecting a TP in the “Port view” and opening the same Performance > Configure Performance Monitoring option in the Port pull down menu (see para.11 on page 133). N.B.

To configure PM for au4CTPs and tuxCTPs, Path Overhead Monitoring (POM) ,Supervised Unequipped Termination (SUT, not supported) or Tandem Connection (TCT, TCM) must be created first (see description in para. 14.9 on page 219 ).

The PM Configuration dialog is designed as a notebook consisting of a text field, to identify the selected TP, and page labels.

1AA 00014 0004 (9007) A4 – ALICE 04.10

The selected TP is indicated in the first box at the top of the screen: TP Identifier.

ED

310 / 426


Use menu item Add TP to display a special TP in the Transmission menu (see para.14.5 on page 203).


In case of au4CTP tuxCTPs and VcxCTP, the PM Configuration dialog also contains a cascading menu that allows to configured the POM/SUT/TC options as follow: –

PathOverhMon After Matrix

–

PathOverhMon Before Matrix

–

TP (Performance is made on AU–PJE )

–

TCM After Matrix

–

TCM Before Matrix

–

TCT Bidirectional After Matrix

–

TCT Bidirectional Before Matrix

When more than one of the above options is chosen, a Question dialog box is displayed (see Figure 218. ); click on Cancel to continue or OK to interrupt any action. N.B.

As long as the PM Configuration dialog is open, a modified POM/SUT/TC configuration is not automatically recognized and displayed. This may lead to rejections or confirmations of forbidden PM configuration. Therefore make sure to reopen the PM Configuration dialog each time the POM/SUT/TC configuration is changed.

Each page label presents a range of parameters for one near end or far end granularity period (15 min. or 24 h) which together form a dataset. To select a special page label, click on the top part of the label: •

NE15, near end 15 minutes page

•

18 SYNCHRONIZATION MANAGEMENT 18.1 Introduction All SDH NEs require timing in order to generate the necessary synchronization and frame phase reference information. The timing can be provided by a source external to the NE or an internal timing generator. The derived timing shall be used for all signals and interfaces in the NE that are related to the SDH frame structure. Follows a brief description of the heart of the NE clock known as the Synchronization Equipment Timing Source (SETS). It can be divided into 2 parts: – –

OSC: the internal oscillator. SETG: the Synchronization Equipment Timing Generator.

The SETG is responsible for the generation of the external timing source for the Frame structure and the clock, whilst the internal oscillator (OSC) is useful only in the abnormal functioning ”Free–running” mode that will be explained later. The simplified figure that follows represents the internal organization of the SETS.

The internal sources (inputs) are: – – –

T1: Reference obtained from incoming STM–N signals, T2: Reference obtained from incoming 2 Mbits signals, T3/T6: Reference obtained from an external incoming 2.048 MHz (T3) or 2.048 Mbit/s (T6) signal. T3/T6 reference clocks are not available on 1640FOX

–

OSC: the internal oscillator.

The number of timing reference inputs depends on the configuration of the NE.

ED

02


337 / 426

– – –

T0: is the reference output signal for the clock and signal frames, T4: is the 2 MHz reference output for the external equipment synchronization. T5: is the 2 Mbit/s reference output for the external equipment synchronization. T5 reference clock is not available on 1640FOX

Other reference points: – –

Y: is used for communication of Synchronization Status Message (SSM) between SETS and MST functional blocks. S15: is used to provide notifications and loss of incoming timing reference reporting to the Synchronous Equipment Management Function (SEMF).

Selector A provides the capability to select timing reference from available T1 inputs, either automatically based on the priority and quality level of the candidate sources (SSM algorithm), or manual as a result of commands issued from the managing system. Selector B is capable of selecting timing reference from T1, T2, or T3/T6 inputs, according to the SSM algorithm. The capability for manual selection of the timing source is also provided. Selector C is only operated in manual mode, to switch between SETG output signal (T0) and a T1 timing reference. The squelch functions A and B mute the relevant timing references in the presence of failure condition, or SSM threshold violation. The choice of the timing reference is done in two ways: – Automatically: Following a particular algorithm based on the quality and the priority of the incoming timing signals. The automatic selection is based either on the priority of the incoming timing source (Priority algorithm) or on the priority and the quality level of the incoming sources (SSM algorithm). – Manually: Following an order from the Operator. N.B.

The priority level is determined by the Operator for each candidate timing source. It is static information. On the other hand, the quality of the source is dynamic information, dependant of the quality of the reference clock generating the timing. In an SDH signal frame, the quality of the timing source is located in the Section Overhead.

1AA 00014 0004 (9007) A4 – ALICE 04.10

The SETG has 3 modes of operation: – Locked mode: The SETG output is fully controlled by the external timing references (T1, T2 and T3/T6). – Hold–Over mode: The external timing reference is malfunctioning. The SETG during normal functioning stores regularly the value of the external timing reference. In this case the SETG output is controlled by this memorized value. – Free running mode: This is not a normal operating mode. The external timing reference and the memorized timing reference are malfunctioning. In this case the SETG output is controlled by the internal clock source.

Before any other operation the synchronization view has to be displayed. 18.2.1 Displaying the Synchronization View The synchronization view can be normally opened using the menu Views options (see Figure 234. ). Using menu options, select the Synchronization option from the Views pull down menu as shown in the following figure.

The Synchronization view shows the external timing reference sources and the T0, T4 or T5, generation. The selection is based on the SSM algorithm or on the priority of the incoming timing sources. Activating the SSM algorithm implies that the selection of the source is before done on the quality criteria and then on the priority criteria for sources at the same quality level. After selecting the Synchronization option from the Views menu the Synchronization View is visualized in Figure 235.

18.2.2 Synchronization View

Synchronization View Description


The synchronization view provides two list of allowable timing references: • •

one for T0 timing output; T0 list is always present; one for T4 or T5 timing output; the presence of the T4/T5 list is configurable using resource files. T0 list contains : –

a timing reference associated to the Internal Oscillator timing source; it is always present and it cannot be removed or redefined.

–

6 max timing reference for candidate inputs belonging to the allowable timing reference T1, T2 or T3/T6 configurable by the operator.

T4 list contains : –

6 timing reference for candidate inputs belonging to the allowable timing reference T1 configurable by the operator.

The T0 and T4/T5 lists are used for the management of reference timing source protection; a 1:n protection like mechanism is used for the selection of the timing source from T0 (T4/T5) list of the allowable timing references, . The protection system chooses the timing reference to generate the output T0 (T4/T5) either automatically, basing on the priority and quality level of the candidate sources according a selection algorithm or manually under control of the managing system. View elements description Here after, the basic component contained in the synchronization view are described: •

Timing reference Each allowable timing reference, , is represented by the graphical object displayed in the view; the timing reference graphical object displays (with the exception of Internal Oscillator timing reference) the following information (if the timing source has been declared by the user): – –

Don’t use (where the highest quality level is G.811 ); or it can be taken as the actual Rx quality, retrieved from the signal received from the line (”Extracted” option). If Input Quality Configuration is set to a value other than ”Extracted”, Rx quality is forced to this value. Click on the Priority: the option button opens the option menu to select the desired priority level. The internal oscillator timing source will have the lowest priority (priority=0) and its priority can not be changed. The other timing sources will have a priority of 1 to n. Priority of 1 is the highest priority. Levels 6,...2 are intermediate levels between level 0 and 1, in increasing order of priority (i.e. 0 6 5 4 3 2 1).

Invoke/Release Lockout: Locking or unlocking a timing source enables or disables the timing source from being considered as a possible timing source for T0 or T4/T5.

b)

Invoke/Release Force and Manual Selection of Timing Source

General selection A timing source can be selected manually or automatically. Furthermore, the selection of a particular incoming timing source (except the internal oscillator) may be forced. This selection is independent of the priority or quality of the timing source. If the timing source is lockout or unavailable, this operation is impossible. A timing source is considered to be available if it is not lockout and has not a failure condition or Priority level of 0. The forced switch mode is terminated by releasing or inhibiting the force selected timing source. The manual selection option is only possible if the quality and priority of the selected timing source are sufficient. Otherwise the automatic selection algorithm overrules the manual selection. If the previously manual selected timing source becomes unavailable the automatic selection is activated. The “Status” indication describes the current synch. status (No Request, Automatic Switch, Failure, ...)

1AA 00014 0004 (9007) A4 – ALICE 04.10

N.B. The internal oscillator cannot be forced or manually selected. From the dialogue box that opens, you can confirm or cancel the operation. To perform or release a T0 or T4/T5 lockout, forced or manual selection, the following operations have to be done: – Select the T0 or T4/T5 source. – Click on the Synchronization menu. – Select the Protection Commands option then invoke/Release the Lockout, Forced or manual Selection option. – Click on Apply in the displayed confirmation box.

18.2.4 Synchronization Protection Commands


18.2.5 Synchronization Configuration for T0/T4 and T4 squelch criteria Select the available T0 or T4 synchronization sources and then the T0 or T4 Configuration... command. This command permits to select/deselect the SSM algorithm, to set the wait time to restore and to enable the revertive procedure if all these features are available. In this NE revertive mode is hardware set, with fixed WTR. In Revertive mode the internal selector A/B (Figure 233. ) changes every time to the best reference clock with the highest quality; on the same quality level basis the reference clock Source with the best priority will be selected. The changing mechanism of the reference inputs is controlled by the wait time to restore: this time sets a delay before to change the input source. Selecting the T0 or T4 Configuration set the SSM algorithm and the Wait To Restore Time in the dialog box upper part of Figure 240. Click on the SSM Algorithm to select/deselect it. Wait To Restore Time button and Revertive option button are disabled Selecting Synchronization –> T4 Configuration it is possible to set the T4 “squelch criteria” in the bottom dialog box of Figure 240. This functionality allows to configure the external timing reference (T4) squelch criteria. The squelch function mutes the relevant timing references in the presence of a failure condition. Squelch may be forced by the Operator or according to squelch criteria which consists in a choice of quality level. Different squelch criteria may be applied: •

when T0 is selected to generate T4 (squelch B Figure 233. ): T0 may be squelched if all the allowable timing references of Selector B have Quality Level lower than the programmable threshold. • when T1 is selected to generate T4 (squelch A Figure 233. ) :T1 may be squelched if T1 Quality Level is lower than the programmable threshold or if it becomes unavailable. The T0/T4 and T1/T4 squelch fields enables the operator to configure the quality level of the T0 or T4 timing source, opening the relevant option menu. When the configuration of T0/T4 Configuration is completed, click on the OK button to validate the choice and close the dialogue box. The T5 output field allows to select the bit used (from #4 to #8) for SSM.

1AA 00014 0004 (9007) A4 – ALICE 04.10

The following suggestions must be considered in the MS SPRING connection configuration:

ED

•

SNCP, 4 Fiber MS SPRING and MSP protection connections cannot be installed in a 2 Fiber MS–SPRING network. This leads to an unprotected connections installation.

•

AU4s from #9 to #16 don’t have to be used for connections nor considered in any parameter of ”Squelching table” provisioning. Only AU4s from #1 to #8 must be used and configured for path installation.

•

19.3 Operative sequence to configure MS–SPRING 19.3.1 Operative sequence to configure 2–Fiber MS–SPRING Next paragraphs list the operative sequence according the type of procedure to obtain. –

Activation procedure

a)

Create an MS–SPRING schema with WTR, Node Identifier, Ring map and the related Squelching Table for each node of the ring, in the desired order. WTR Ring must be the same in all the nodes.

b)

In the Main dialog for MS–SPRing management select “ACTIVATE” in each node of the ring, in the desired order. Consider that, in this step, “Default K byte West or East” detection by View Protection Status Parameter (under MS–SPRing label –> “Protocol exception”), will occur on those Ports connected to the nodes not provisioned yet with the MS–SPRing protection “created” (active).

c)

Verify in the View Protection Status Parameter screen, at the end of the provisioning update, that all the nodes of the ring are in “MS–SPRing active” and “No request” state.

–

Deactivation procedure

a)

In the Main dialog for MS–SPRing management select “DEACTIVATE” in each node of the ring. Consider that, in this step, “Default K byte West or East” detection by View Protection Status Parameter (under MS–SPRing label –> “Protocol exception”), will occur on those Ports of the activated nodes connected to the nodes just deactivated.

b)

In the Main dialog for MS–SPRing management select “DELETE” in each node of the ring.

–

Removing a node

a)

In the Manage ring Map view select the node and click on the”Remove Node” button.

b)

Modify the table in the Configure Squelch Table view according the new Ring Map.

c)

Opening the View Protection Status Parameter screen, send “Force Ring” command to both NE’s adjacent to the node to be removed.

d)

Physically remove the node.

e)

Connect the fibers and send the “Release” command of the relevant “Force Ring” to both NE’s adjacent to the removed node.

–

Adding a node

a)

In the Manage ring Map view insert the node in the selected position. Next nodes are automatically shifted. Modify the table in the Configure Squelch Table view according the new Ring Map. Opening the View Protection Status Parameter screen, send “Force Ring” command to both NE’s adjacent to the node to be added. Physically add the node and configure with 2–Fiber MS–SPRING activated with the right configuration (Ring Map, Squelching table, WTR, Node Identifier). Connect the fibers and send the “Release” command of the relevant “Force Ring”to both NE’s adjacent to the added node.

19.4.3 Activate, Deactivate and Delete commands The Main Activities commands ( Figure 256. on page 365) manage the MS–SPRing configuration. The MS–SPRing status can be Enable, Active, Disable and Inactive. After having configured the protection schema by means of the Create button, the status becomes Enable . The Activate button selection enables the MS–SPRing protection mechanism on the selected schema configuration. To change from Active to Enable click on the Deactivate button. This command starts the request to deactivate the MS–SPRing protection mechanism. When the selected protection schema is Enable the Delete button starts the request to remove it. The delete action is started after confirming the window message Figure 272. .

The external protection commands are : Lockout, Force, Exercise (not operative in current release),Manual, WTR. The lockout commands disable the MS–SPRing management. The lockout section presents six lockout commands, four operative ( Figure 275. ). Each lockout command is applicable on different points where the lockout actions has to be performed ( Figure 276. ) and any “Lockout” command is associated to a “Release “ command to come back to the previous status. Term “Span” identifies the section interested by the command, it doesn’t assume the Span meaning of the four fiber protection.

19.5.2 External commands (2F)


The protection events can be equipment/signal failure, signal degrade or external command or a combination of them. The “Events” will be served if some actions (B/S=bridges and switches) are executed and the network has been updated. The “Events” will be signalled if the K1/K2 protocol communicates to the network nodes what has happened, without execute actions. A single ring failure is completely restored but not two ring failures. When are present multiple ring failures the automatic B/S protection will try to maintain on all the possible connections. The K1/K2 communication protocol MS–SPRing is generated from the two nodes adjacent to “Event” via the protection communication channels. A node is defined tail –end when it firstly receives the “Event”, the second node is defined head–end when it receives back the protocol answer. Figure 277. shows the association of tail–end / tail–end or head–end / tail–end. Some network protection mechanisms are accepted or rejected depending on the end type (tail/head) (lockout command,...)

1AA 00014 0004 (9007) A4 – ALICE 04.10

With the lockout protecting span command and a ring failure, the ring protection is served if this ring failure occurred along the same section; the ring protection is disabled if the ring failure has occurred in another ring section. On the contrary, with the lockout working ring command failure and a ring failure along a different section, the ring protection is served ((protection not disable). See Figure 279.

1AA 00014 0004 (9007) A4 – ALICE 04.10

The Manual command is similar to Force command but it is at a lower priority level with respect to automatic MS–SPRing. The general priority scale that can be applied to solve antithetical situations starting from the lowest priority level is: manual ring – automatic working ring – force ring – lockout Working Ring – lockout Protecting Span. When a force ring command is applied a next working failure is not able to modify the forced configuration applied. That is because force ring command has a higher priority respect to the “Automatic” working protection. In this condition the ring can be split according the location of command and event. Vice versa the “Manual” protection is exceeded by the “Automatic” protection. Figure 283. visualizes the ring protection with a Force/Manual command and a signal failure. FS–R is for “Force Switching Request”, SF–R is for “Signal Failure Request”.

Two Lockout commands are both always served: B Force command has priority with respect to the Manual one. Automatic protection has priority with respect to the Manual command. Force Ring and Automatic Protection (or two Force ring commands) are always served if they are not applied on the SS–SN. In this last case has to be considered the priority level. The behavior is that seen for two automatic protection switching ( Figure 288. ) Lockout working SS–SN has priority with respect to Manual, Automatic protection and Force commands. In the other cases, both commands are served (B). Lockout protection SS–SN / OS–AN and Manual or Automatic or Force command are both served because the switching SS–SN / OS–AN channels are not managed by the lockout protection: B.

1AA 00014 0004 (9007) A4 – ALICE 04.10

Lockout protection SS–AN / OS–SN overrides the Manual or Automatic or Force command because the lockout protection controls the switching channels of the same Node. Lockout protection SS–RN / OS–RN and manual or automatic or force command: the lockout protection prevents the working 1–8 channels from being inserted into the protecting 9–16 ones. The lockout protection is served, because it has a higher priority, the ring protection will be only signalled (pending).

19.5.4 2F Protection Status Visualization


The protection statuses ring network are: –

1 – Lockout Switching

–

2 – Forced Switching

–

3 – Automatic Switching ( MS–MSPRing protection for equipment/signal failure ).

–

4 – Manual Switching

–

5 – Idle ( regular operation without MS–SPRing protection )

These protection states are represented with the following color state boxes: –

Green: Active State, No Request condition.

–

Red: Inactive State and any external or protection executed command ( that has been served ).

–

Yellow: ordered but not executed command ( that has only been signalled= pending status ).

–

Greyed: not available state box.

Automatic switching and external commands are revertive: then when the “Events” have been cleared, the MS–SPRing configuration comes back to its idle status. The state boxes visualize the “Node Condition Request” as a consequence of the equipment/signal failure or the external commands detected on the corresponding side (”Event”). The state boxes don’t describe the protection actions provided on the NEs. The served “Events” ( B/S=bridges and switches are executed and the network has been updated ) are completed B/S actions visualized as red box indications The signalled “Events” ( the K1/K2 protocol communicates to the network nodes what has happened ) are pending B/S visualized as yellow box indications.

1AA 00014 0004 (9007) A4 – ALICE 04.10

Figure 291. shows the protection status with a served East manual ring command. Any protection status window is divided in different status fields: Schema description and status, Local Conditions, Node Conditions and Protocol Exceptions. The first one describes the network configuration and application type and its status, the second gives the local external commands indications, the third the “Events” results on the nodes and the fourth one checks the k1/k2 ring protocol. The window is divided into three parts: West, Middle and East. On the West there are all the box indications corresponding to the West protections and commands. In the middle “WTR–Ring” refers to West and East sides, “No Request” corresponding to “Idle Status”, and “Intermediate Node” denotes that the protections and commands don’t concern the node involved. The Manual Ring command visualizes “Manual Ring” on the local node and “Request Node Ring” in the both “Local Conditions adjacent East ADM1–West ADM2 nodes, while the 3 and 4 nodes are “Intermediate Node”. The red color means that the command has been served. A regular protocol “Exceptions” is represented with white boxes, a protocol alarm is signalled with red boxes. The “Prot. Unavailable” indications are activated when a lockout protection command is applied in a network node.

20 ISA PORT CONFIGURATION 20.1 Introduction This Chapter describes the operations necessary for the ISA boards creation (ATM, PR_EA, PR, ETHERNET) in the Equipment view and the ISA TTPs creation; as a matter of fact ISA boards does not crate TTPs when they are configurated. The ISA board creation is performed (following the same rules of all the other SDH/PDH ports as explained in paragraph 9.2 on page 116) when a CT user sets an ISA board and then configure the IP Address (as described in paragraph 8.14 on page 104). For the TTPs creation refer to paragraph 20.2 where all the operation are explained. For the ISA traffic configuration (for example creation of Hard/Soft cross connection, PNNI configuration etc.) refer to the relevant OPERATOR’S HANDBOOK (ATM, PR or PR_EA) where “Specific Terminal” application is explained in details. The operational sequence to follow to manage ISA cross–connection is: a)

ISA board declaration (Equipment Set)

b)

ISA IP Address Configuration ( Called ISA board IP Address) (not needed for ISA–PR and ETHERNET boards)

c)

ISA board TTPs creation (VC4XV , VC12XV, VC3XV, VC4–4c TTP, VC4 TTP, VC3 TTP, VC12 TTP, s31 TTP, E1 TTP) (not needed for ISA–PR board)

d)

TTPs cross–connection ( refer to paragraph 15.3 on page 254) (not for ISA–PR board)

e)

ISA traffic configuration with “Specific Terminal” application

20.2.4 Gigabit/s ETHERNET board

[1]

10/100Mbit/s Ethernet board (ETH–MB)+GBIT Access (GETH–AG); this feature is supported only on 1650SMC and 1660SM. With this architecture can be configurated up to 2 TPs (VC4XV TTP Type concatenation level=1) on the GETH–AG access card and up to 11 TPs (VC4 TTP, VC3 TTP, VC12 TTP, s31 TTP, E1 TTP Type) on the ETH–MB main board taking into account that the maximum throughput must not exceed 622 Mbit/s.

[2]

GIGABIT board (GETHMB) stand–alone; this feature is supported on all OMSN (1640FOX, 1650SMC and 1660SM). With this architecture can be configurated up to 4 TPs (VC4XV Type) on each board taking into account that the maximum throughput must not exceed 622 Mbit/s in 1640FOX and 1650SMC (for example it is possible to configure 1 port VC4XV with a max. concatenation level equal to 4 or as alternative 4 ports VC4XV with concatenation level equal to 1). The same rule above described are applicable to 1660SM when the GIGABIT board (GETHMB) is equipped in normal slot (i.e. slot with a throughput of 622 Mbit/s). In 1660SM are also available slot called “enhanced” (25, 26,28,29,34,35,37,38) where the throughput per board is 1.2 Gbit/s. If the GIGABIT board (GETHMB) is equipped in one of these slot it is possible to reach a max. concatenation level equal to 7 per port ; of course this means that there is only one VC4XV with concatenation level =1 available for another port and no resources for the last two ports present on the board. For more details read the Gigabit Ethernet description reported in the Technical Handbook.

[3]

GIGABIT board (GETH–MB) + GBIT Access (GETH–AG); this feature is supported only on 1660SM. With this architecture can be configurated up to 4 TPs (VC4XV Type) on the GETH–AG access card and up to 4 TPs (VC4XV TTP Type) on the GETH–MB main board taking into account that the maximum throughput for the “couple” must not exceed 1.2 Gbit/s.; the concatenation level per port can be from 1 to 7. In order to support this architecture the GETH–MB board must be equipped in the “enhanced” slot (25,26,28,29,34,35,37,38) and GETH–AG access in the associated slot (respectively 3,4,6,7,15,16,18,19).

21 SOFTWARE MANAGEMENT 21.1 Generalities and descriptions The Craft Terminal provides a set of functions which allow software packages manipulation within NEs. The downloading operation consists in the establishment of session between the NE and a software server for the purpose of file transfer. Actions can then be performed on the NE software version as update and activation operation, or roll back to the previous software version operation. In this way the NE can follow the product evolution with “in service” equipment. The same function is used during maintenance phase, to update spare boards for substitution after troubleshooting. The operations that can be undertaken in this section are: – – –

display Software Download Information, initiate / Abort Software Package Download, manage Software Packages within NEs, activating the downloaded Software Package or coming back to the previous condition.

A backup/restore can be also done on the MIB of the NE. Indeed the MIB can be saved to or restored from the mass storage of the Craft Terminal. The software download general principle is represented in the following figure.

21.1.1 Naming Conventions

–

Software Package: Software Package stands for a piece of software which can be executed by an NE of a particular type. It consists in one or more Software Units and a Descriptor File. A software package is identified by its name, release, version and edition. On the NE (i.e. once downloaded) a software package can be: – the active version: the software package currently running on the NE – a standby version: a software package which is neither the active version nor the boot version

–

Software Unit: A Software Unit is a part of a software package which can be either executable code or a data segment of a particular board within an NE. A software unit is also identified by its name, release, version and edition.

–

Descriptor File: A Descriptor File contains information about the software package it belongs to and lists the composing software units. Each software package must have a descriptor file otherwise it would not be possible to interpret the content of the package.

–

Software Management Function: The Software management function offers information about all current software packages present in an NE. Indicators enable software management (running package, activated package, etc...).

The following software version states are available: • Commit (active) version: the software version currently running on the NE. • Standby version: is a software version which has been downloaded on the NE but which is not in the active state. Two main functions are involved in the software downloading: – Software Download Manager function – Software Download Server function The Software Download Manager function takes the downloading and management requests of the operator and sends them to the NE. Thus, this function enables a download process to be initiated and monitored by the operator. It manages the NE software releases and initiates software download operations.

1AA 00014 0004 (9007) A4 – ALICE 04.10

The Software Download Server is only responsible for fulfilling the requests received from NEs and performing software package file transfer operations to the NE.

The naming conventions used for Download Management are the following:

21.2 Software download operative sequence


Two main different operative condition are defined for this Equipment: •

First installation of an OMSN The NE is received without the relevant software install. The software download must be done as described in the SIBDL section of this Handbook.

•

Updating an OMSN with an already installed software. Follow the operative indications of para. 21.2.1 on page 419 .

21.2.1 Software Download upgrade N.B.

In order to migrate from Release 1.1A to a Higher Release, the download procedure requires two steps. The first is from 1.1A to 1.1X (intermediate package) and the second is from 1.1X to the Higher Release (e.g. 1.1B1).

In order to update the following procedure is to be done as explained in the next steps: a)

Install on the PC the NE Software Package present in the CD–ROM (refer to 1320CT Basic Operator’s Handbook for details).

b)

open a session on Craft Terminal application (start–up of the application, start supervision and NE login)

c)

Check the present status of the software on a selected NE.

[3] Station supervisory center: the maintenance technician refers to the Remote Alarms received from the equipment in a centralized office of the station i.e. :


Units Alarms: Each port card or access card of the equipment is provided with a bicolor LED (green/red) or multicolor LED (green/red/yellow) at the bottom of the front coverplate. Bicolor LED indicates: – when red, internal failure (indicates that the unit concerned must be replaced) – when green, in service unit Multicolor LED indicates: – when red, internal failure (indicates that the unit concerned must be replaced) – when green, in service unit – when yellow, means that the unit is part of an EPS schema and its status is “standby” (only available on 1650SMC and 1660SM)

AC/DC Rectifier Alarms: (only for 1640FOX) The AC/DC is provided with four LEDs on the front coverplate, which indicate (from top to bottom): • • • •

Red LED: detection of an INTERNAL alarm (rectifier failure or rectifier fans failure) Yellow LED: battery charging Red LED: AC mains off (missing of AC power) Green LED: rectifier is operating

ATM unit Alarms:

1AA 00014 0004 (9007) A4 – ALICE 04.10

All the alarm detected on the unit are related to the ATM traffic management; on the front coverplate are present optical indication (LEDs) with the following meaning (from the top to the bottom):

ED

•

Red LED : detection of an MAJOR or CRITICAL (URGENT) alarm

•

Red LED : detection of a MINOR (NOT URGENT) alarm

•

Yellow LED : alarm condition ATTENDED

•

Yellow LED : detection of an ABNORMAL operative condition.

•

Yellow LED : detection of an WARNING (INDICATIVE) alarm

02


15 / 82

All the alarms detected on the units are collected by the “Controller” unit (called EQUICO in 1660SM, SYNHT1N or SYNTH4 in 1640FOX/1650SMC) unit which will deliver centralized optical indications (by means of LEDs on its front coverplate). Specifically, from the top to the bottom : •

Red LED: detection of an URGENT (MAJOR and CRITICAL) alarm

•

Red LED: detection of a NOT URGENT (MINOR) alarm

•

Yellow LED: alarm condition ATTENDED

•

Yellow LED: detection of an ABNORMAL operative condition. Type: active loopbacks, forcing the unit into service, laser forced ON or OFF, try to restore after ALS

•

Yellow LED: detection of an INDICATION (WARNING) alarm

The analysis of these LEDs permits to detect the alarm type (Urgent – Not Urgent – Indication) and relevant condition (Abnormal condition, Attended). In case of URGENT or NOT URGENT alarm, after having located the alarmed equipment, the alarm condition can be ”attended” by pressing the relevant alarm storing push button on the EQUICO unit. This condition causes: –

5.3 On site Troubleshooting


The trouble–shooting operation proceeds according to the information indicated in the flow–charts: –

Figure 1. on page 18: General flow–chart

–

Figure 2. on page 19: Flow–Chart for 1660SM/1650SMC Power Supply alarm

–

Figure 3. on page 20: Flow–Chart for 1640FOX Power Supply alarm

and according to para.5.4 on page 21. As indicated in the flow–charts the troubleshooting operation is done by means of the Craft Terminal, and of the optical indicators (LEDs) present on the NE. The Craft Terminal is cord–connected to the relative connector on the “Controller” unit (EQUICO/SYNTH1N/SYNTH4) front coverplate (F interface). The Craft Terminal applications provide detailed information on the alarm state thus facilitating fault location and subsequent removal as indicated in para. 5.4 on page 21. To correctly execute the troubleshooting operations the technician must know the exact equipment configuration (see Equipment Configuration applications on the Craft Terminal). The aim of the flow–charts which follow and of the maintenance tables is to locate the faulty unit and to replace it with a spare as well as to locate a failure along the link.

1AA 00014 0004 (9007) A4 – ALICE 04.10

The flow–charts/tables should be also consulted when the unit LEDs flash, because the flashing condition might be due to external alarm causes usually related to line problems.

5.4 Troubleshooting by means of the Craft Terminal. The troubleshoot proceeds checking the detailed information on the NE alarm by means of the craft terminal. The information on the NE alarm will be mainly obtained by means of the craft terminal through the Alarm Surveillance data and the alarms/status indications presented in the various views, depending on the level of the structure under observation. Navigation across the various level views is done from higher to lower levels, by double clicking on the objects (see instructions on “NE management” section). The NE hierarchy is organized in the following order: NE > rack > subrack > board > port > TP. The troubleshoot procedure with the the Craft Terminal consists of the following steps: a)

An example of alarms/status view organization is shown in Figure 5. pg. 23. Observe the active alarms on the Severity Alarm Synthesis, Domain Alarm Synthesis and Management States Control Panel always present on the window (it resumes all the NE alarms). Table 2. on page 24 describes the meaning of these alarms/statuses and the relevant maintenance actions.

b)

in case of alarm presence, access the Alarm Surveillance to troubleshoot. This application gives the details of the detected alarms and helps for their localization. Para 5.4.4 on page 26 describes this view.

c)

It is possible to analyze the detailed alarm presence on the TPs of each ports of the NE, following the indication of para 5.4.5 on page 34.

d)

It is also possible to check alarm and status at Board view, Subrack view and Equipment view are also supplied following the indication of para 5.4.6 on page 41 and para 5.4.9 on page 48.

e)

Eventual housekeeping alarms can be localized following the indications given in para. 5.4.10 on page 51.

f)

These above said paragraphs describe general aspect of alarms meaning and relevant maintenance actions that can be done with the information given in the applications.

g)

The history of past events can be obtained by means of the Event log option of the Diagnosis pull down menu (see “NE management” section).

In case of unit replacement, follow the indications reported in Chapter. 6 on page 53. Troubleshooting with Automatic Laser Shutdown

1AA 00014 0004 (9007) A4 – ALICE 04.10

The Automatic Laser Shutdown (ALS) is used to protect the operator who is working with the optical fiber. When the ALS is active, it may be difficult to detect the link failed. To locate it, it is necessary to ”force on” the ALS, thus enabling the optical power transmission on the opposite direction of the failed link. WARNING: During this phase the operator has to pay attention when working with fibers and connectors. The ABNORMAL indication inform the operator of the ALS forced condition. After having completed the maintenance, enable the ALS. The ALS states are indicated in the port view, as described in para. 5.4.5 on pg. 34.

The following concepts and definitions are considered useful to facilitate maintenance operations with the aid of the previously indicated tables. The various units specified in the synchronous multiplexing hierarchy imply structuring the Transmission network into three levels (sublevels of the physical OSI level): –

Transmission bearer level. It is the support for the path level and can be further split into physical level (Transmission media) and Transmission section level. The sections can be either regenerator or multiplexer and utilized for specific functions associated to the EOW channels of the SDH frame. The interface alarms (or section alarms, indicated in the tables) belong to this level (example: Line LOS, LOS, B2etc.).

–

Path level It concerns the data transfer between the access points and the path. It does not depend on the service nor on the type of Transmission media. It constitutes the circuit level support. The path can be either lower order (LO) or higher order (HO) depending on the capacity of data transferring. Like the regenerator and multiplexer sections, the paths too have specific functions associated to the EOW channels of the SDH frame. The alarms listed in the cited tables, where path level troubleshooting is required, belong to this level (example:TUAIS, TU LOP).

–

Circuit level. This level concerns the transfer of information between the access points and the circuit proper. It is a direct support for the telecommunication services. It superimposes the SDH function and is considered as the transport agent hence no SDH order–wire channel associated functions are required. An example of this level alarm is Tributary LOS.

The above level structuring in the Transmission network is depicted in Figure 4.

It is also possible to analyze the detailed alarm presence on the TPs of each ports of the NE, following the indication of the Port View chapter on the previous Section of this Handbook. Figure 8. to Figure 12. are examples of Port view. For each TP of the Port a detail of the relevant alarms is presented. On the port view the messages displayed at the bottom provide information about: –

MSP protection (if enable); refer to Figure 9.

–

Automatic Laser Shutdown state; refer to Figure 8.

–

State of the connection for Ethernet port (available only if an ethernet port has been selected); refer to Figure 11. and Figure 12.

A message under the mouse indicator provides the name of the alarm or object on which it is located, in this way facilitating the identification of the alarm or status or object. The non–alarmed condition of an alarm icon is represented by a green color and a “–” sign in the box. The alarmed condition is represented by the color of its severity (as assigned by the ASAP) and an “X” sign in the box. The alarms which can be found in the Port view are listed in Table 7. on page 29, where the relevant maintenance actions are reported too. The information regarding ALS states and Laser state useful for operators safety purpose are reported in the following: ALS states: Inactive = No ALS has been activated (Off) or the laser has been Forced ON/OFF. In test = The laser restart has been automatically activated . Active = The ALS has been activated (On). Undefined = The ALS is not present (not created). Laser state: On = all OK or ALS not present (not created). Off = Laser off (when ALS is created). Forced on = ALS forced on by operator command.

5.4.6 Board view alarms and states The alarm and status indications at Board level can be obtained, following the indication of the Board View chapter on the previous Section of this Handbook. Figure 14. and Figure 15. are examples of Board view. The alarm and status indications depend on the unit type; for example SDH units is organized on two levels of presentation (in the first is selected one of the available ports) and each view contains dedicated indications. An alarm box is displayed on each port, to indicate whether the port is alarmed. An indication in the ”message/status area” provides information about the board Administrative State: “in– service” or “out–of–service”. The alarms of the board are reported at the bottom of the ”message/status area”, by means of various boxes containing relevant acronyms. The non–alarmed condition of an alarm icon is represented by a green color. The alarmed condition is represented by the color of its severity (as assigned by the ASAP). A message under the mouse indicator provides the name of the alarm or object on which it is located, in this way facilitating the identification of the alarm or status or object. In the view is present the Administrative State information: “in service” or “out of service”. The alarms which can be found in the Board view are listed in Table 6. page 28, where the relevant maintenance actions are reported too. In the view can also be present EPS indications (if supported by the equipment) Sub–board alarms In case of board with multi access points (i.e. containing “sub–boards”) another view permits to select the contained port, named “daughter” or “sub–board” (see example of Figure 14. page 42). An example of “daughter” (sub–board) view with the presented ports is in Figure 13. on page 42. It is displayed after clicking on it.

6.6 CONGI unit replacement

1AA 00014 0004 (9007) A4 – ALICE 04.10

When substituting an “old” CONGI unit (from code 3AL 78830 AAAA to code 3AL 78830 AAAE) with a “new” CONGI unit (starting from code 3AL 78830 AAAF) must be taken into account the rules reported in the following; this is necessary for the right management of the “Fuse Broken” alarm on the CONGI (1650SMC and 1660SM) and SERGI (1650SMC) units. [1]

The alarm “Fuse Broken” is meaningful (hence it is active) only if two batteries connections (this means that two CONGI in1660SM or one CONGI and one SERGI in 1650SMC has been equipped) are present.

[2]

If “old” CONGI units are present in main slot (slot 10 for 1660SM and slot 4 for 1650SMC) it is mandatory to connect the service battery to the front connector (refer to Installation Handbook for details) to correctly activate the alarms.

[3]

In presence of configurations having 2 CONGI units composed of an “old” and “new” type it is mandatory to open TC5 setting (refer to Technical Handbook for details on Hardware settings) on the soldering side of the “old” type CONGI if the latter is placed in the spare position (slot 12 in 1660SM and slot 5 in 1650SMC). If the “old” CONGI is maintained in a main slot (slot 10 in 1660SM and slot 4 in 1650SMC), TC5 can be nevertheless closed or open.
