Troubleshooting
Monitoring a D-channel
In the course of Troubleshooting we may wish to watch the messaging on the D-channel of a particular
PRI. This would help determine whether or not the CS1000 (or the AudioCodes Gateway) is truly trying
to send or receive calls. You can monitor D-channel messages, as well as see the digits that are sent and
received for call setup in LD 96 of the CS1000
>ld 96
DCH000
.enl msgi 33
(This turns on D-channel messaging monitoring for inbound calls on D-channel #33)
OUTPUT TARGETS: TTY
.enl msgo 33
(This turns on D-channel messaging monitoring for outbound calls on D-channel #33)
OUTPUT TARGETS: TTY
.
The below shows the system’s output when initiating a call from Unistim Extension 3404 to extension
7010 that resides on the AudioCodes Gateway
DCH 33 UIPE_OMSG CC_SETUP_REQ REF 0000000B CH 33 23 TOD

You may also gather a great deal of information about calls to and from the Mediant Gateway by
examining the output of the Mediant Gateway’s syslogs. Syslog output will show called and received
numbers on the PRI as well.
