and 8–13 (slots 6 and 7 are reserved for SRP modules). In the ERX-310 router,
the line module slots are numbered 0–2 (slot 0 is reserved for the SRP module).

port —Number of the port on the I/O module. On the CT3/T3 12 I/O and E3-12
FRAME I/O modules, ports are numbered 0–11.

Before You Configure an Interface
Before you configure a T3 or an E3 interface, verify that you have installed the line
modules and I/O modules correctly.
You need the following information for each T3 controller:
■
Framing type
■
Clock source
■
Cable length
You also need HDLC channel information, such as data inversion information, for
interfaces that support HDLC.
