Preview to Alarms For the Alarm Management the Alarm Surveillance (AS), which is a generic component of the ALMAP product, is used. A complete user guide of the AS can be found in the 1330AS Rel. 6.5 Operator's Handbook", which is also available as online help. To open the online help use the Help" menu of the AS dialogs. In this chapter only a short overview of the main functionalĆ ity of the Alarm Management is provided.
2.1
Current Alarms Management When an alarm is raised by a resource (or by a neighboring one) detecting a fault, it is received by the Alarm SurveilĆ lance which stores it and warns the operator by ringing a bell or by the appearance of a specific icon on the screen. The alarm may be displayed as soon as it is signalled accordĆ ing to the operator needs. During the whole period an alarm is considered to be current (CLR or NCLR), its state is permanently realĆtime refreshed so that any operator who displays the alarm is informed if it has been reserved or not, if it has been acknowledged or not, if a trouble ticket has been requested for this alarm or not. The alarm is cleared by the emitting resource as soon as the problem is no longer present at the resource. Then the alarm is no longer considered as a current alarm and as soon as it is acknowledged by the operator it disappears from the current alarm set and is archived to the set of historical alarms. Deleted alarms also disappear from the sublist (or Main List) and are archived, if matching the archiving filter. However, the problem to which the alarm is linked may not be solved immediately. In such a case the alarm is repeated after a while until the problem is solved. Alarm Surveillance associates a repetition counter to each received alarm. Furthermore, if the alarm is not cleared at all by the reĆ source which raised it before for any reason, the Alarm SurĆ veillance offers the possibility to archive it manually on the operator's request.
3AG 24197 ACAA - Ed. 04

2.2
Alarm Counter Available global information is displayed by counters that show the number of alarms of a single severity level as well as the total number of alarms in the sublist, and the number of non acknowledged and cleared alarms. These counters may be realĆtime refreshed (when the sublist is active) or not (when the sublist is inactive). After confirming unacknowledged alarms, the alarm counter are changed as follows: -
NACK" is decreased according to the number of confirmed alarms
-
ACK" is increased according to the number of confirmed alarms
Clear" is increased as soon as an alarm is cleared.

Example of Sublist Displaying Unacknowledged Alarms
3AG 24197 ACAA - Ed. 04
Because of the overwrite behavior in the alarm lists (autoĆ matic deletion of old alarms by the system in order to create new memory capacity) or after manual deletion of alarms by the operator, an existing alarm correlation may not be visible anymore, i.e. the begin alarm is deleted, but the corĆ responding end alarm is still part of the unacknowledged alarm list.
3AG 24197 ACAA - Ed. 04

2.3
Alarm Information Alarms or Alarm notifications consist in messages emitted by resources that have detected problems or failures. Information contained in the alarm includes -
information that identifies the resource which has raised the alarm
-
information that identifies the type of the problem the alarm refers to.
Note that these pieces of information are mandatory in any alarm notification, as well as the date and time the alarm has been raised by the resource. Other optional information such as the specific problems the alarm is linked to, the notiĆ fication identifier, etc., may also be present to help the operator in the alarm management process. The operator can create alarm sublists accustomed to his/ her preferences, including filtering and display of alarm inĆ formation. For more information about alarm management and alarm (subĆ)lists refer to the 1330 AS Rel. 6.5 OperaĆ tor's Handbook. To obtain more information about the element that has reĆ ported the alarm, it is possible to navigate to this element: -
Mark the alarm in the alarm list and select External Application Ć> emlusm" of the Navigation" menu.
Depending on the Event Type the Equipment or TransmisĆ sion View is opened and the affected element is selected (i.e. framed in orange). In these Views you can also access the Alarm Reference Guide (this handbook) as online description:

3AG 24197 ACAA - Ed. 04
2.3.1
Perceived Severity The entry Perceived Severity indicates the severity level of the problem when the alarm is raised. Malfunctions are ranked into five severity levels:
2.3.2
-
Critical, when it is no longer possible to provide the service requested by the user, e.g. it is applied for "server" boards in cases where more than one "client" board is affected by this failure (due to an underlying serverĆclient relationship).
-
Major,
-
Minor,
-
Warning, which means no impact is reported upon the quality of service offered to the user,
-
Indeterminate, if the severity level cannot be defined by the resource which raises the alarm. (Possible reason are incorrect ASAP settings.)
-
Cleared, if the alarm is cleared by the resource which has raised it before.
Event Date & Time This entry indicates date and time when the alarm was raised on the resource. The data is displayed as YYYY/MM/DD hh:mm:ss E.g. 2004/05/20 06:29:24 indicates an alarm that was risen at 29 minutes and 24 seconds past six o'clock in the morning, on the 20th of may 2004.
3AG 24197 ACAA - Ed. 04
11
2.3.3
Friendly Name With the help of the friendly name it is possible to locate the element that has reported the alarm. The friendly name includes information about the NE and the location of the element where the alarm was risen. DeĆ pending on the alarm's event type, the element type can be a board or a TP. For equipment alarms the location is givĆ en down to board level. Communication and quality of serĆ vice alarms include a further entry identifying the port and the TP. Quality of service alarms also provides an alarm type giving threshold crossing information. The general format of the friendly name equals NE/rack#subrack#slot#/port#ĆTP If we take the marked entry from Figure 1 as an example: Anlage84/r01sr2sl16/port#01ĆElRsCTP indicates an alarm raised by ElRsCTP on port 1 of the board on slot 16 in subrack 2 of rack 1of NE Anlage 84".
2.3.4
Event Type The entry Event Type" indicates the alarm type taken out of the following ones: -
Quality of Service
-
Communications
-
Processing Error
-
Equipment
-
Environmental Alarms
Hardware or control system errors are reasons for an Equipment alarm, Environmental alarm or ProcessĆ ing Error alarm. Transmission errors are the reason for Communication alarms. Threshold problems are the reason for Quality of Service alarms.
2.3.5
Probable Cause The probable cause indicates the error reason (e.g. Loss of Frame).
12
3AG 24197 ACAA - Ed. 04
2.3.6
Reservation Status The operator can reserve a current alarm to make sure to be the only responsible for this alarm. In this case the reservation status of the selected alarm changes from NRSV (non reserved) to RSV (reserved). An alarm can only be unreserved by the operator who has reserved it before.
2.3.7
Clearing Status A current alarm that has not been solved is indicated as NCLR (not cleared). As soon as the problem is no longer present at the resource, its status changes to CLR (cleared).
2.3.8
Acknowledgement Status Unacknowledged alarms are marked NACK in the list and can be confirmed by the operator. The statuses of the seĆ lected alarms change, passing from NACK (non acknowlĆ edged) to ACK (acknowledged). Note that acknowledging a cleared alarm is an implicit archiving action. Thus, the acknowledgement actually archives the alarm and causes its disappearance from the current alarm list.
2.3.9
Correlated Notification Flag If a correlation notification is sent together with the reĆ ported alarm, this flag will be set to YES.
2.3.10 Repetition Counter The repetition counter indicates the number of times an alarm was sent by a resource.
3AG 24197 ACAA - Ed. 04

2.4
Alarm Severity Assignment Profile (ASAP) An ASAP is a list containing probable alarm causes to which severities are assigned according to their service dependenĆ cy. Alarms are indicated at the CT according to the assigned ASAP, displaying the assigned severity, or are not indicated at all. I.e. the ASAP is used as an alarm filter.
2.4.1
DefaultĆ and FreeĆuse ASAPs There are two types of ASAPs: -
the predefined default ASAPs which include all potential probable causes/severities raised by the NE. These ASAPs are defined as readĆonly, i.e. it is not possible to modify their contents and it is not possible to remove them.
-
the user defined ASAP created by the user. A user defined ASAP can also be removed by the managing system. The number of severities and of probable causes is fixed. Their characteristics cannot be modified. The ASAP function only enables the modification of the seĆ verities assigned to the probable causes, it does not alĆ low the addition, removal or modification of the probĆ able causes themselves.
The following five ASAPs are configured as default ASAPs: -

ASAP: No Remote Alarms This ASAP enables the indication of all primary communication alarms plus SSF (AIS and RDI are disabled) and equipment alarms.
-
ASAP: All Alarms This ASAP enables the indication of all alarms. This is the default ASAP for MSTTP.
-
ASAP: No Server Alarms This ASAP enables the indication of all alarms except SSF, Redundant Clock Fail A/B and Redundant Matrix A/B Failure.
Service Dependency Depending on its effect on service, each probable cause can be assigned an alarm severity in the ASAP. This is called serĆ vice dependency. There are three service dependency types:
3AG 24197 ACAA - Ed. 04
-
Service Affecting
-
Non Service Affecting
-
Service Independent.
15
Some restrictions apply to the assignment of a severity to service dependency. Table 1 lists all the different allowed cases of severity assignment and service dependency. Case
Service Affecting
Non Service Affecting
Service Independent
1
critical or major
minor or warning or nonĆ alarmed
not used
2
critical or major
not used
not used
3
not used
minor or warning or nonĆ alarmed

4

critical or major or minor or warning or nonĆ alarmed
Table 1
Permissible Assignment of Service Dependency and Severity Note, that the 1678MCC handles the service dependency types service affecting" and non service affecting" only in respect of Replaceable Unit Missing (RUM) alarms (plug out of a board). All other alarms are handled with severity type service independent". This means that when cloning an ASAP, cases 1 to 3 of Table 1 can only be applied to RUM alarms (it is recommended to use Case 1 if RUM should apĆ pear as alarm and Case 3 if RUM should not appear as alarm). All other alarms should be configured according to Case 4.
2.4.3
Severity Objects (TPs and Equipment) emitting alarms reference to default ASAPs with exception of the following cases: -
16
Whenever an object cannot evaluate the ASAP, e.g. due to a wrong provisioning of the manager, the alarm is emitted with the severity indeterminate".
3AG 24197 ACAA - Ed. 04
2.4.4
Contents of Predefined ASAPs on the 1678MCC The 1678MCC handles the service dependency types serĆ vice affecting" (SA) and non service affecting" (NSA) only for replaceable unit missing (RUM) alarms (plug out of a board). All other alarms are handled with severity type service independent". Therefore, in the following tables, SA and NSA severity dependency is only mentioned for this alarm.

The probable cause families Quality Of Service and EnviĆ ronmental cannot be configured via ASAP. The only Quality Of Service probable cause is Threshold Crossed". The severities for Threshold Crossed can be conĆ figured via the PM Threshold Tables (see CT Operator's Handbook, Chapter “PM Threshold Table Create/Modification/Display”). The severities for Environmental probable causes can be configured in the Station Alarm Configuration dialog (see CT Operator's Handbook, Chapter “Configuration of Station Alarms”).

Table 13
Correlation of Element Type and Alarm Type with Threshold Alarms All quality of service alarms shown in the alarm list (see Chapter 3, Table 12 ) are threshold alarms. As a precondiĆ tion for reporting threshold alarms, performance monitorĆ ing has to be enabled for the corresponding TPs. Threshold alarms (15min and 24h) are reported if the preset threshĆ olds are exceeded. Threshold alarms (15 min.) are automatically cleared after one error free 15Ćmin.Ćinterval. Threshold alarms of 24ĆhĆ intervals are automatically cleared after midnight or have to be cleared by the user. Alarm type explanation: The alarm type is part of the Friendly Name and indicates the assignment of the threshold to near or far end attribĆ utes and to a granulatity period (15 min. or 24h). Threshold alarms of the following types are reported in the alarm list if performance monitoring is enabled for the corĆ responding element:
