Configuring D Channels
The MGX 8260 Media Gateway communicates with PSTN equipment over Primary Rate Interface
(PRI) ISDN D Channels.
Adding D Channels
Adding a D Channel requires an existing DS3 line and suitable DLSAP and MACSAP profiles. To add
a D Channel, follow these steps:
Step 1 Specify the D Channel parameters using the adddchan command, as described in the “adddchan”
section on page 9-6.
adddchan 11.1 1 1 24
Step 2 Verify the configuration using the lsdchan command.
