In cases in which the two main modules do not have the same configuration,
update to the other card configuration.
³
To update card configuration:
1.
Go to Configuration>System>Protection>Main card redundancy.
2.
Select Configuration Update to other card.
³
To extract the log file:
1.
Go to Monitoring>System>Event log>View event log.
2.
Alternatively, under the active alarms list, go to Monitoring>System>Active
alarms.
In case of consecutive switch over between modules, try to increase the Wait
to Restore time. This defines the length of delay required between two
consecutive switch operations. The WTR time can be changed only when the
redundancy protection is turned off.
3.
To change the WTR, go to Configuration>System>Protection>Main card
redundancy and under WTR time, specify a different time.
1. Card redundancy > (On)
2. WTR time (sec)[1 - 60] ... (5)
4.
If this error persists, contact Tech Support.
Underruns – TDM Pseudowire
The Jitter buffer failed to compensate PSN packet delay variations.
The PDV (Packet Delay Variation) Buffer is used to compensate for PDV in PSN
networks. When the network PDV exceeds the configured depth of the Jitter
buffer, an Underrun will occur, resulting in jitter buffer re-initialization process.
Underruns may also be related to clocking mis-configuration or a fault of the
remote TDM interface, which results in a termination of transmission.
³
To correct PDV related underruns:
1.
Go to Monitoring>Applications>Multiservice over PSN>PW>Statistics.
