CT3/T3-F0 line modules and CT3/T3 12 I/O I/O modules to support the following:

Interface Stack

Figure 3 on page 49 shows the stack for T3 ATM interfaces. Figure 4 on page 49
shows the stack for T3 frame and E3 frame interfaces.
To configure a T3 ATM interface, first configure a T3 controller. To configure ATM
parameters, see Configuring ATM in JUNOSe Link Layer Configuration Guide .
To configure a T3 frame or E3 frame interface, first configure a T3 or E3 controller,
and then configure a High-Speed Data Link Control (HDLC) data channel on the
controller.

NOTE: For a detailed description of interface types and specifiers, see Interface Types
and Specifiers in JUNOSe Command Reference Guide. For information about interfaces,
see Planning Your Network in JUNOSe System Basics Configuration Guide.

Numbering Scheme

This section describes how to identify T3 and E3 interfaces.
A T3/E3 controller on an ATM or frame interface is identified using the slot/port
format, where:
Clocking
Redundancy
Frame Relay logical interface support
Unique IP interface support for each PPP or Frame Relay PVC interface
Line speeds of 45 Mbps
slot Number of the slot in which the line module resides in the chassis. In
ERX7xx models, line module slots are numbered 2-6 (slots 0 and 1 are reserved
for SRP modules). In ERX14xx models, line module slots are numbered 0–5 and
