Troubleshooting Using Cisco PGW 2200 Softswitch Alarms
Corrective Action
To correct the problem, either stop the provisioning session as described in the “Ending a Provisioning
Session Without Activating your Changes” section on page 3-66. Alternatively, you can save and
activate your changes according to the method described in the “Saving and Activating your
Provisioning Changes” section on page 3-65.
PRI: B-Channel not available
This alarm occurs when the Cisco PGW 2200 Softswitch receives a PRI “setup” message and the
requested B channel is not available or cannot be allocated to the call.
Corrective Action
If necessary, you can save and activate a provisioning session, as described in the “Saving and Activating
your Provisioning Changes” section on page 3-65.
ProcM No Response
The process manager is not responding to state information changes from the failover daemon.
Corrective Action
To correct the problem, perform the following steps:
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 Stop the Cisco PGW 2200 Softswitch software on the standby Cisco PGW 2200 Softswitch, as described
in the “Shutting Down the Cisco PGW 2200 Softswitch Software Manually” section on page 2-4.
Step 3 Restart the Cisco PGW 2200 Softswitch software on the standby Cisco PGW 2200 Softswitch, as
described in the “Starting the Cisco PGW 2200 Softswitch Software” section on page 2-2.
Step 4 Perform a manual switchover, as described in the “Performing a Manual Switchover” section on
page 3-96.
Caution Switchover operations cause the loss of all SS7 messages that are sent to the Cisco PGW 2200 Softswitch
for approximately three seconds. The switchover affects unstable in-progress calls as well as new calls.
Stable in-progress calls are not affected.
Step 5 Stop the Cisco PGW 2200 Softswitch software on the newly standby Cisco PGW 2200 Softswitch, as
described in the “Shutting Down the Cisco PGW 2200 Softswitch Software Manually” section on
page 2-4.
Step 6 Restart the Cisco PGW 2200 Softswitch software on the newly standby Cisco PGW 2200 Softswitch, as
described in the “Starting the Cisco PGW 2200 Softswitch Software” section on page 2-2.
If restarting the software does not resolve the problem, proceed to Step 7.
