Network fault management
The system handles network fault management through the reporting
of alarms and logs to the Management Module. RTP Media Portal
alarms and logs are viewed from the System Management Console.
For further details related to alarms, please refer to MCS 5100 Fault
Management: Alarm and Log Reference (NN10385-900).
Fault tolerance
The RTP Media Portal provides base capabilities that significantly
improve the performance and reliability of the system in the event of a
fault. These capabilities include:
• Dynamic Pool Registration
— provides the basic mechanism that ensures resource availability
and utilization in the event of a SIP Application Module loss of
communications with gateway controllers. This is accomplished
through the generation of periodic registration messages (over
the control channel) to each of the gateway controllers
configured for the RTP Media Portal. This function works in
tandem with SIP Application Module redundancy to ensure that
RTP Media Portal resources continue to be used in the event of
a SIP Application Module failure. The RTP Media Portal is
configured to advertise its availability with the Standby SIP
Application Module. This configuration enables the Standby SIP
