Resolving SS7 Network Related Problems
Resolving an Association Alarm
When an alarm indicates a failure on an association, perform the following steps:
Step 1 If you have not already collected system data, refer to the method that is described in the “Collecting
System Data for Cisco TAC” section on page 6-93.
Step 2 If this alarm occurs along with the LIF FAIL alarm on the failed destination address, proceed to Step 3.
Otherwise, proceed to Step 5.
Step 3 Verify the functioning of the cabling between the Cisco PGW 2200 Softswitch and the destination
address.
If the cables are functioning properly, proceed to Step 4.
If you find bad cables, replace them. If replacing a cable resolves the problem, the procedure is complete.
Otherwise, proceed to Step 4.
Step 4 Verify if the associated Cisco switch is functioning.
If the switch is functioning properly, proceed to Step 5.
If the switch is not functioning properly, see the documentation for your switch for troubleshooting
information. If that corrects the problem, the procedure is complete. Otherwise, proceed to Step 7.
Step 5 Debug the IP connectivity between the Cisco PGW 2200 Softswitch and the associated external node.
If the IP connectivity is working correctly, proceed to Step 6.
If the IP connectivity is not working correctly, see the documentation for the external node to determine
a method to identify and fix the IP connectivity problem. If that corrects the problem, the procedure is
complete. Otherwise, proceed to Step 6.
Step 6 Determine the health of the associated external node.
If the external node is working correctly, proceed to Step 7.
If the external node is not operating properly, see the documentation for the external node for
troubleshooting information. If that corrects the problem, the procedure is complete. Otherwise, proceed
to Step 7.
Step 7 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.
Converting Stored and Sent Point Code Values
If you are troubleshooting signaling problems, you might encounter point code values displayed in
hexadecimal or decimal. You must convert these values to understand which point code is affected, or
the value that the Cisco PGW 2200 Softswitch sends. To convert and stored and sent point code values,
complete the following steps:
Step 1 Convert the hexadecimal or decimal value to binary code.
For example, if you found a log message indicating a problem with a point code in a ITU SS7 connection
that is identified with a hexadecimal value of 00:00:36:33, the converted binary value is
00000000000000000011011000110011.
