Troubleshooting Using Cisco PGW 2200 Softswitch Alarms
C7LNK CONGESTION
This alarm occurs when an SS7 MTP2 link becomes congested and it cannot receive any more messages.
Corrective Action
If this alarm occurs repeatedly, perform the following steps to correct the problem:
Step 1 To collect system data, see the method that is described in the “Collecting System Data for Cisco TAC”
section on page 6-93.
Step 2 Reduce the amount of traffic from the far-end that is associated with the affected link.
If that clears the alarm, the procedure is complete. Otherwise, proceed to Step 3.
Step 3 Add additional links to the linkset associated with the affected link. See

If that does not resolve the problem, proceed to Step 4.
