Chapter 6 Troubleshooting the Cisco PGW 2200 Softswitch Platform
Resolving Bearer Channel Connection Problems
Note You can configure the Cisco PGW 2200 Softswitch software to issue individual or group supervision
messages for point codes that are associated with an ISUP signaling service. ISUP signaling services
issue group supervision messages by default. If you configure an ISUP signaling service to issue
individual supervision messages, specifying the range option causes the system to issue individual
supervision messages for each CIC in the range, instead a single group supervision message.
For example, to unblock CIC number 1 through 20, which are associated with a signaling service called
ss7svc1, enter the
unblk-cic:ss7svc1:cic=1,rng=19 command.
To verify that the CICs are successfully unblocked, retrieve the status of the affected CICs as described
in the “Verifying CIC States” section on page 3-15. If the CICs are still blocked, see the “Resetting
CICs” section on page 6-140.
Unblocking Remotely Blocked CICs
Generally, you cannot unblock a CIC that was blocked remotely, because the block was set on the
far-end. However, in some instances, a remotely blocked CIC is misreported. You can fix this problem
by resetting the CIC as described in the “Resetting CICs” section on page 6-140.
Resetting CICs
When trying to clear a blocked CIC or range of CICs, you might need to perform a reset on the affected
CICs by issuing the reset-cic MML command.
Note The reset-cic MML command is not supported for signaling services that use variants of the BTNUP
protocol.
To reset a single CIC, log in to your active Cisco PGW 2200 Softswitch, start an MML session and enter
the
reset-cic: sig_srv :CIC= number command.
Where:
• sig_srv—MML name of the signaling service that is associated with the CICs to be reset.
• number—Number of the affected CIC.
For example, to reset CIC number 2, which is associated with a signaling service called ss7svc1, enter
the
reset-cic:ss7svc1:CIC=2 command.
To reset a range of CICs, log in to your active Cisco PGW 2200 Softswitch, start an MML session, and
enter the
reset-cic: sig_srv :CIC= number ,RNG= range command.
Where:
• sig_srv—MML name of a signaling service that is associated with the CICs you want to reset.
• number—Number of the first CIC in the range of CICs you want to reset.
• range—Number such that number+range is the number of the last CIC in the range of affected CICs.
All CICs between number and number+range are displayed.
