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.
For information about installing line modules and I/O modules in ERX routers, see ERX
Hardware Guide, Chapter 4, Installing Modules.

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.
