Troubleshooting Using Cisco PGW 2200 Softswitch Alarms
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 Ensure that the near-end and far-end data link terminations are operating.
If the near-end or far-end data link terminations are not operating, fix as necessary.
If the near-end and far-end data link terminations are operating, proceed to Step 3.
Step 3 Ensure that the provisioning settings for the signaling channel match the settings that are used on the
far-end, as described in the “Retrieving Provisioning Data” section on page 3-69.
If the configuration data for the signaling channel is incorrect, begin a dynamic reconfiguration session,
as described in the “Invoking Dynamic Reconfiguration” section on page 3-66.
If the configuration data for the signaling channel is correct, then proceed to Step 4.
Step 4 Contact the Cisco TAC to analyze the problem further and to determine a solution. For more information
about contacting the Cisco TAC, see the “Obtaining Documentation and Submitting a Service Request”
section on page xviii.
SC M-OOS
This alarm occurs when a signaling channel has been taken out of service manually.
Corrective Action
To correct the problem, restore the affected signaling channel to the in-service state, using the
appropriate procedure. Procedures for modifying the state of signaling channels are described in the
“Setting the Service State of a C7/SS7 Link or Linkset” section on page 6-105, the “Setting the Service
State of an IP Link” section on page 6-105, and the “Setting the Service State of a D-channel” section
on page 6-106.
SG Node Interface Fail
This alarm occurs when all IP connections to a signaling gateway (SG) node are out of service.
Corrective Action
To correct the problem, check the configuration of the SG node and, if necessary, configure it to connect
to the Cisco PGW 2200 Softswitch.
SG Pair Interface Fail
This alarm occurs when all IP connections to both SGs of a pair or a single nonpaired SG are out of
service.
