Configuration Tasks for Ports
Changing Voice Ports
You can change any of the optional parameters for an existing port. To change a voice port, use the
chvport command, specifying the same parameters as required to add a voice port. For example, to
change the echo tail while leaving other parameters unchanged, type the following command:
chvport 13 1 # # # # # 2
The system changes the echo tail for logical port 1 in slot 13 to tail24ms.
Deleting Voice Ports
To delete a voice port, enter the delvport command, specifying the logical slot number of an NSC and
the logical port number for an existing voice port. For example, this command deletes port 4 of slot 13.
delvport 13 4
Viewing Voice Port Configuration and Status
To view the information for a single voice port, enter the lsvport command, specifying the logical slot
number of an NSC and the logical port number for an existing voice port. The system displays detailed
