Chapter 6 Troubleshooting the Cisco PGW 2200 Softswitch Platform
Resolving Bearer Channel Connection Problems
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 Cisco PGW 2200 Softswitch”
section on page 3-56.
Setting the Administrative State of a Media Gateway
To set the administrative state of an associated media gateway, 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: gway : state command:
Where:
• gway—MML name of the media gateway.
Note Not all media gateway types are applicable. Supported types are CU, MUX, MGW, and AVM external
nodes.
• state—Administrative state that you want to set. The following states are valid:
– Lock—Makes all bearer channels that are associated with the media gateway 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 media gateway 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.
– Reset—Clears local and remote blocking on the bearer channels that are associated with the
media gateway and these bearer channels take the blocking state of the remote side.
For example, to set the administrative state of a media gateway called sfgway to lock, enter the
set-admin-state:sfgway:lock command.
Step 2 Verify that the state of the media gateway changed by entering the rtrv-admin-state MML command,
as described in the “Retrieving the Administrative State of a Media Gateway” section on page 3-56.
Setting the Administrative State of a Trunk Group
To set the administrative state of a trunk group, 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: trkgrp : state command.
Where:
• trkgrp—MML name of the trunk group.
