■
Clocking

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:
■
slot —Number of the slot in which the line module resides in the chassis. In
ERX-7xx models, line module slots are numbered 2-6 (slots 0 and 1 are reserved
for SRP modules). In ERX-14xx models, line module slots are numbered 0–5
