Chapter 6 Troubleshooting the Cisco PGW 2200 Softswitch Platform
Resolving Bearer Channel Connection Problems
Where:
• sig_srv—MML name of the signaling service. The following signaling service types are valid for
this command:
– In-band TDM up to MUX and then time switched to TDM media and sent to the Cisco PGW
2200 Softswitch.
– In-band TDM signaling up to CU and then encapsulated and sent over IP to the Cisco PGW 2200
Softswitch.
– In-band TDM signaling up to the media gateway and then converted to NI2 and sent to the
Cisco PGW 2200 Softswitch over IP (that is, FE box<-sig/tdm->media gateway<-NI2/IP->
Cisco PGW 2200 Softswitch).
– Signaling service or routeset that is associated with a DPC.
– EISUP signaling service.
• number—Valid CIC number.
• range—Value such that y+range is a valid CIC number. The administrative state for all CICs
between y and y+range are retrieved.
• state—Administrative state. The following states are valid:
– Lock—Makes all bearer channels that are associated with the CICs unavailable for call
processing. If the state is set to lock, active calls on the affected bearer channels go into pending
state, where calls remain until either party voluntarily releases the call. New calls are disallowed
on the affected bearer channels.
– Unlock—Makes all bearer channels that are associated with the CICs available for call
processing. If the state is set to unlock, the CICs become available. New calls are allowed to use
the affected bearer channels.
– Reset—Clears local and remote blocking on the bearer channels that are associated with the
CICs and these bearer channels take the blocking state of the remote side.
For example, to set the administrative state of CICs 2 through 11, associated with a signaling service
called ss7svc1, to lock, enter the
set-admin-state:ss7svc1:cic=2,rng=9:lock command.
Step 2 Verify that the state of the Cisco PGW 2200 Softswitch changed by entering the rtrv-admin-state MML
command, as described in the “Retrieving the Administrative State of CICs” section on page 3-59.
Querying Local and Remote CIC States
In the course of troubleshooting bearer channel problems, you might need to query the local and remote
states of the related CICs to verify that they match. To query the local and remote states of a single CIC
or a range of CICs, log in to the active Cisco PGW 2200 Softswitch, start an MML session, and enter the
query-cic: sig_srv :cic= number [,rng= range ] command.
Where:
• sig_srv—MML name for the signaling service that is associated with the affected CICs.
• number—Number of the first CIC in the range of affected CICs.
• 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.
