For more information about specific parameters, see "E1 Interfaces Overview" on
page 561, "E3 Interfaces Overview" on page 569, "T1 Interfaces Overview" on page 577,
and "T3 Interfaces Overview" on page 587. For a configuration example, see
"Examples: Configuring Channelized DS3-to-DS0 Interfaces" on page 497.
For information about Frame Relay DLCI limitations for channelized interfaces, see
"Data-Link Connection Identifiers on Channelized Interfaces" on page 396. For more
information about Frame Relay DLCIs, see "Configuring a Point-to-Point Frame Relay
Connection" on page 388. For more information about DLCI sparse mode, see the
JUNOS System Basics Configuration Guide.
Each T1 link can have up to eight DS0 channel groups, and each channel group can
hold any combination of DS0 time slots.

Configuring Channelized DS3-to-DS1 Interfaces

You can configure 28 T1 channels per T3 interface, and each interface can have
logical interfaces. To specify the channel number, include it after the colon (:) in the
interface name. For example, a 4-port T3 PIC in FPC 1 and slot 1 will have the
following physical interfaces, depending on the media type:
where
To configure channelized DS3-to-DS1 interface properties, you can include both the
