Chapter 6 Troubleshooting the Cisco PGW 2200 Softswitch Platform
Resolving Bearer Channel Connection Problems
– Unlock—Makes all bearer channels that are associated with the signaling service available for
call processing. If the state is set to unlock, the media gateway becomes available. New calls are
allowed to use the affected bearer channels.
For example, to set the administrative state of a signaling service called nassrv1 to lock, enter the
set-admin-state:nassrv1: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 a Signaling Service” section on
page 3-57.
Setting the Administrative State of Spans
To set the administrative state of a single span, perform the following steps:
Step 1 Log in to the active Cisco PGW 2200 Softswitch, start an MML session, and enter the
set-admin-state: sig_srv :span= x : state command.
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.
• x—16-bit value that identifies an ISDN/PRI physical cable.
• state—Administrative state. The following states are valid:
– Lock—Makes all bearer channels that are associated with the span 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 span available for call
processing. If the state is set to unlock, the span becomes available. New calls are allowed to
use the affected bearer channels.
For example, to set the administrative state of span number 2, associated with a signaling service called
ss7svc1, to unlock, enter the
set-admin-state:ss7svc1:span=2:lock command.
Step 2 Verify that the state of the bearer channels changed by entering the rtrv-admin-state MML command,
as described in the “Retrieving the Administrative State of Spans” section on page 3-57.
