Channelized DS-3 to DS-0 Interface Naming

You can configure 28 T1 channels for each T3 interface. Each T1 link can have up to eight DS-0 channel groups, and each channel group can hold any combination of DS-0 time slots. To specify the T1 link and DS-0 channel group number in the interface name, use colons (:) as separators. For example, a Channelized DS-3 to DS-0 PIC might have the following physical and virtual interfaces:

ds-0/0/0:x:y

where x is a T1 link ranging from 0 through 27, and y is a DS-0 channel group ranging from 0 through 7. See the JUNOS Internet Software Network Interfaces and Class of Service Configuration Guide for more information about ranges.
