6.9 Rerouting at Alarms
As of SOX Version 5.5 the alarm rerouting is supported. This function can
be executed manually at a Single/Multi user system and automatically at a
Multi user system. With this function it is possible to reroute circuits which
are affected by alarms. For this Trunks are monitored for appropriate
alarms. Which faults are activating the rerouting function is defined in the
alarm list. The list of the alarms you can find in chapter Section 6.8.1, Alarm
list . The alarms are marked in the column “Default for Alarm rerouting” with
an X.
Trunks/Circuits which shall be taken into account for rerouting must be
configured. This configuration will be done during the configuration of the
Trunks/Circuits via the "Trunks" or "Circuits" menu -> "Annotations &
Routing" -> "Automatic routing" using the "Eligible for Rerouting on Alarms"
function check box. For circuits additonally a "Priority for Routing" can be
configured. This priority is used for rerouting on alarms and will be taken into
account during the analysis. The higher the priority is the rather the circuit
will be taken into account for rerouting.
At the appearance of one of the predefined alarms at a Trunk configured for
"rerouting" the system carries out an analysis on possible redirections. With
this analysis informations about the affected Trunks/Circuits will be
determined. The result of this analysis provides the possible rerouting. The
result is displayed in a information window. In this information window you
can specifiy the details of information which shall appear.
Note: Rerouting on alarms is non-revertive. This means that there
is no switchback after the switch criterion is no longer available.
Single user system
The analysis for “Rerouting on Alarms” must be carried out manually via the
„Special Tasks“ menu. The analysis provides the result for possible
rerouting. With the “Reroute Circuits with Alarms” menu the circuits will be
rerouted.
