T3-62
Note: A3T3:45Mb/s Access Card
ALCATEL 1660SM
In case of 45Mb/s interface, a further configuration is needed, compared with 34Mb/s interface, due to the fact that a different approach is specified for DS3 in the American standard.
In fact, in case of DS3, the central Office cable must be equalized at transmit side, by doing the appropriate pre-setting, through the Craft Terminal, in order to maintain constant reference level at the Distribution Frame.
The Port card P3E3/T3 is the same for 34 and 45 Mb/s.
The Access card (A3E3 or A3T3) is different for 34 Mb/s (E3) and 45 Mb/s (T3), due to this fact the DS3 (45) interface must be equalized at transmit side by inserting the appropriate LBON (Line Built Out Network).

Notes:Local Configuration window
ALCATEL 1660SM
Local Configuration window allows to configure: The Network Address of the NE: this address must be selected in agreement with Alcatel, or in any case, with the responsible Authority for the DCN. Intermediate System type : L1 or L2 are selected according to the network partitioning into areas. Select L2 only for a Gateway NE which communicates with OS located in a different Network Area. All NEs inside the same area are L1. This configuration is not mandatory. It is only useful to speed-up the OSI protocol routing. OSI Stack Selectors keys (Presentation, Session and Transport Selectors) : these are usually fixed and they are only used by protocol specialists, to optimize OSI protocol processing in complex network. Notes: Up to 3 different Network Addresses can be assigned to the same NE. The Ethernet Address(MAC) is not in this window: it is fixed inside the NE (read only). Network Addresses must be known when configuring the CT for remote control. Other parameters concerning with Local Configuration are: • NTP Configuration data (see next slide) • OS Configuration data: see the relevant window • LAPD Configuration data: see the relevant window (User/Network name must be assigned to SDH ports used for DCC, with a coherent order: start with Network and then follow an alternate User/Network/User sequence).

Protection State & Commands
ALCATEL 1660SM
"Span" identifies the section interested by the command
T3-148
Notes: Protection State & Commands
ALCATEL 1660SM
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 signaled 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 headend when it receives back the protocol answer.
T3-149
Protection State & Commands:lockout
ALCATEL 1660SM
If the node is tail-end, the lockout working ring command disable the protection MS-SPRing mechanisms,
if the node is head-end, the lockout working ring serves the request node protection (protection not disable).
the lockout working ring command failure and a ring failure along a different section, the ring protection is served (protection not disable).
T3-150
Notes: Protection State & Commands:lockout
ALCATEL 1660SM
Lockout working ring is normally used only for test. This command works in different way if the node is Trail or Head in the connection.(pay attention!)
T3-151
Protection State & Commands:lockout
ALCATEL 1660SM
The lockout protecting span command disable the protecting direction. If you have a 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.
T3-152
Notes: Protection State & Commands:lockout
ALCATEL 1660SM
Lockout protecting span is normally used only for test
T3-153
Protection State & Commands:forced & manual
ALCATEL 1660SM
The Force command executes a forced protection. The Force Ring command substitutes the working channels (AU4 1 to 8) with the opposite direction protection channels (AU4 9 to 16) between two adjacent nodes. NOTE:The Force Span command is not operative in 2 fiber MS-SPring.
The Manual command is similar to Force command but it is at a lower priority level with respect to automatic MSSPRing. The general priority scale (if you give the command on the same port): lockout Protecting Span. lockout Working Ring force ring automatic working ring manual ring
T3-154
Notes:forced & manual
ALCATEL 1660SM
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. FS-R is for "Force Switching Request", SF-R is for "Signal Failure Request

ALCATEL 1660SM
To create a cross-connection: start from Add TP in Transmission menu It is necessary to Terminate and to Structure an AU4, before executing a cross-connection involving a Tu-n within an STM-n port ( not needed for AU4 to AU4 CxC). After terminating and structuring an AU4, cross-connections can be executed between Vc-n and Tu-n (e.g. between VC12 and TU12). The windows involved in creating a cross-connection are: Main window, to select the Transmission menu Cross-connection Management window, to display the cross-connections and to start Create/ Modify/Delete a cross-connection (Opened from Transmission/Cross-Conn. Mgt. menu) Main Cross-Connection window, to define the cross-conn. type and to select input/output (opened from Create/Modify, in Cross Conn. Mgt. window) TP Search window, to select the Termination Points (open from Choose in Main Cross-Conn. window) Note: this is one of the possible options to create cross-connections.

T3-180
Notes: Cross-Connection management
There are many different procedures to create, modify, delete cross-connections. As general approach, the Operator can start from Cross Connection Management window, opened from Transmission menu.
To create, modify, delete a cross-connection: Open Equipment View window, by double clicking on the Rack View window Select Transmission in View menu Select Transmission in bar menu – Select Cross-connection – Select Cross-connection management: – Cross-Connection Management window opens – Select Search with the desired filter :the list of existing cross-connections will appear. Select a cross-connection (a line) to enable Modify Create is enabled if the local Operator is authorized by the OS and if not-connected TP are available.

8 In the following, the Cross-connection Management is described trough four examples, corresponding to four objectives. The first two objectives are: 8Objective 1: to connect a 2 Mb/s port to an STM16 interface 8Objective 2: to bypass a VC12 through two STM16 ports.

Cross-Connection management: practical rules
ALCATEL 1660SM
Type of cross connections “bulk”: Cross-connect Au4 to Au4 or Tu-n to Tu-n when (you don’t care about the content); a PDH signal has to be inserted/extracted into/from an SDH signal: Cross-connect a Vc-n to Tu-n ( or VC-4 to Au4) Search TP: VC-n inside PDH Port Cards AU4 inside SDH Port Cards TU-n inside the Matrix
Max 64 ports
PDH Port (VC-12)
Max 96 ports
MATRIX (TU-n) (VC-4)
SDH Port (AU4)
Max 96 VC4 ports
T3-182
Cross-Connection management: practical rules
ALCATEL 1660SM
The described rules have to be remembered by heart, to avoid waste of time. Remember that: the matrix has 96 ports, referred to bulk Au4’s (HPC) and 64 ports referred to structured VC4’s (LPC).Only the LPC ports are displayed in the CxC Management window; e.g.: no matrix port is displayed when cross/connecting Au4 to Au4. The Matrix automatically selects the VC4 port to be connected to an Au4, when the AU4 is Terminated: – 1 port is occupied when a P63E1(or P3E3) is configured (warning!: this is the port #1 only at the beginning, if it is the first time the equipment is configured) – 1 port is occupied when a P3E3 is configured – The other ports are occupied in sequence while implementing CxC’s...
When an Au4 (or a VC4) is Terminated, it means that it is structured till Tu3: this is represented as a cross-connection between Au4 and VC4.
But!: if the Au4 was previously configured with VC12: then Terminate TP means also Structure TP ! (make some trials to understand!)

The Objective of this procedure is: to connect a 2 Mb/s port to an STM16 interface. This is the operation which is usually done to drop/insert a PDH signal from an SDH stream. In this example it is assumed that the cross-connection is bidirectional and not protected. Procedure is quite similar in case of monodirectional or protected cross-connection and it is carried out in two steps: Configure a Tu12 held into an Au4 as cross-connection input; Configure a VC12 as cross-connection output (or viceversa) The operator should have in mind the following scheme:

Alarms on Cross-connections
ALCATEL 1660SM
Example: AU-AIS Alarm at AU4 level in a cross-connection from VC12 to AU4
T3-232
Notes: Alarms on Cross-connections
ALCATEL 1660SM
Typical situations with a wrong cross-connection are: • SSF at Vc-n level • AIS detected on an external instrument. Typical alarm when a Cross-connection is not correctly working is SSF, in Port View: this alarm is usually caused by a wrong cross-connection or, unlikely, by HW failure. This alarm is also active if Unequipped is received in the Signal Label from the remote Node. SSF causes AIS on the PDH port. Note: this AIS is usually detected by an external instrument only; it is detected in the port view only for framed 2Mb/s incoming signal. The example shows the Transmission View window in case of cross-connection from VC12 to AU4; the window is opened from Port View window by selecting: Navigate to Transmission View, after selecting a VC4; In the example:the cross-connection is not operating due to a failure alarm at AU4 server layer: this alarm should cause also SSF at VC4 and at VC12 (in the Port view windows). Further details on alarms can be displayed by selecting a TP an then selecting Port /Navigate to Port View: the Matrix connections are displayed with alarms associated to the connected TP’s (see next slide). Warning!: to display the alarm, the correct alarm severity table must be setup for the AU4 block . Some severity tables do not display the alarm for AU-AIS. T3-233
