JUNOS 10.1 Network Interfaces Configuration Guide
Configuring Primary Rate Interfaces
Primary rate interfaces are a combination of B-channels with one controlling
D-channel for the group. Configure B-channel interfaces for each time slot that you
want to function as an ISDN PRI interface. The B-channel is used for data, video,
voice, and multimedia. You can create:
To configure B-channels on a channelized T1 interface, include the

This configuration creates interfaces
ds-pim/0/port:3
Use the same configuration to create B-channels on a channelized E1 interface by
including the
hierarchy level.
One D-channel is used between switching equipment in the ISDN network and the
ISDN equipment at your site for signaling. For channelized E1, the D-channel must
be time slot 16. For channelized T1, the D-channel must be time slot 24.
To configure a D-channel on a channelized T1 interface, include the
