Chapter 6 Troubleshooting the Cisco PGW 2200 Softswitch Platform
Resolving Bearer Channel Connection Problems
Step 9 Define the D-channel on the associated media gateway. See the documentation for the media gateway
for information on how to define a D-channel.
The procedure is finished.
Step 10 Start a provisioning session as described in the “Starting a Provisioning Session” section on page 3-64.
Step 11 Delete the appropriate D-channels using the prov-dlt:iplnk:name=” ip_link ”,... command.
Where:
ip_link—MML names for an IP link that was identified in Step 3.
For example, to delete a D-channel that is named bh531-31, enter the
prov-dlt:iplink:name="bh531-31" command.
Step 12 Delete the signaling service that is associated with the D-channel using the
prov-dlt:ipfaspath:name=” sig_serv ” command.
Where:
sig_serv—MML name for a signaling service that was identified in Step 5.
For example, to delete a signaling service that is named bh531-3, enter the
prov-dlt:ipfaspath:name="bh531-3" command.
Step 13 Activate your new configuration as described in the “Saving and Activating your Provisioning Changes”
section on page 3-65.
Unblocking CICs
You may need to unblock a CIC or a range of CICs on the Cisco PGW 2200 Softswitch. There are two
types of blocking on a CIC, local and remote.
Unblocking Locally Blocked CICs
To unblock a single CIC, log in to your active Cisco PGW 2200 Softswitch, start an MML session and
enter the
unblk-cic: sig_svc :CIC= number command.
Where:
• sig_svc—MML name of the signaling service that is associated with the CICs that you want to
unblock.
• number—Number of the affected CIC.
For example, to unblock CIC number 2, which is associated with a signaling service called ss7svc1, enter
the
unblk-cic:ss7svc1:CIC=2 command.
To unblock a range of CICs, log in to your active Cisco PGW 2200 Softswitch, start an MML session,
and enter the
unblk-cic: sig_svc :CIC= number ,RNG= range command.
Where:
• sig_svc—MML name of a signaling service that is associated with the CICs you want to unblock.
• number—Number of the first CIC in the range of CICs you want to unblock.
• 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.
