DSI SS7G41 Signaling Server – SIU Mode Release Notes
Release 2.2.3
22
Presentation of large amounts of data now uses tables and allows the user to
select the data rather than needing to scroll through the whole table. The
number of line displayed per view is user configurable and data tables can be
sorted (by clicking the head of the column) or filtered (by clicking on the
required data component value).
2.12
Alarm Log Enhancements
This release includes a number of enhancements to the operation of the
Alarm Log mechanism which result in format changes to the ALLIP (Alarm
List) command and the alarms.log CSV text file and the addition of the date
and time of alarm occurrence.
A new command, ALLOP, provides alarm log history. The command is similar
to the ALLIP command except that it reports the previous 1000 alarm events
(occurrence or clearing of alarms).
Alarm events are also archived to the text file ‘alarm.log’ in the syslog/alarms
sub-directory of the ftp account.
The following alarm log fields have been added or modified:
NODE – A new user configurable field providing a short-form identity of the
unit. This is displayed on the browser interface, on the MMI interface at login
and included on a per alarm event basis in the SNMP ALARM MIB and the CSV
format alarms.log file. The field is up to 9 alphanumeric characters and is set
using the CNSYS command.
SEQUENCE – Sequential reference number of an entry in the alarm log since
the last restart.
CODE – Numeric identifier of the alarm code. Each alarm condition has a
unique CODE value.
STATE – Current state of the alarm which can be Active, Acknowledged (the
alarm is still active but has been acknowledged by an operator) or Cleared.
The user can acknowledge an alarm using the browser interface or using the
new ALLIS command specifying the SEQUENCE parameter.
SEVERITY – Perceived severity of the active alarm (previously called CLA).
TITLE – Descriptive title for the alarm code. The text for some alarm types
has changed slightly from the previous release to align with the values
reported for SNMP events.
TYPE – Classification of the alarm into an alarm type from the following list:
communicationsAlarm (2), qualityOfServiceAlarm (3), processingErrorAlarm
(4), equipmentAlarm (5) and environmentalAlarm (6). This field replaces the
previous Category (CAT) field so the STSYP command no longer lists the
count of alarms in the following categories: System, PCM and Protocol.
CAUSE – Probable cause for the alarm code based on the principles of ITU
Recommendations M.3100, X.733, and X.736 and GSM 12.10 (ETS 300 618).
The values used are defined in the DSMI-TC MIB (V3.00).
DIAG1, DIAG2 – Additional diagnostic information provided on the occurrence
of an alarm. The meaning of these fields varies based on the alarm code.
The new command ALCDP lists for each CODE the assigned SEVERITY, TYPE
and CAUSE.
The STSYP and STSWP commands now report the count of “Warning” alarms
in addition to the existing counts of “Critical”, “Major” and “Minor” alarms.
