Step2 Insert the DB68 connector at one end of the 4E1/8E1 conversion cable to the DB68 interface on the

MIM-IMA-4E1/MIM-IMA-8E1 module, and fasten the cable retaining screws.

Step3 Identify the sequence numbers of the connectors at the other end of the 4E1/8E1 conversion cable

and connect one connector (or a pair of connectors) to the peer device.

Step4 Power on the router. Check the status of the LINK LED on the MIM-IMA-4E1/ MIM-IMA-8E1 module

panel. OFF means the line has problem and signal is out of synchronization. In this case, please check
the line.

MIM-IMA-4T1/MIM-IMA-8T1 Module

Introduction

The 4-port/8-port T1 ATM inverse multiplexing interface module (MIM-IMA-4T1/MIM-IMA-8T1) provides
four/eight T1 interfaces that support the IMA technology. Their network application is similar to that of
the MIM-IMA-4E1/MIM-IMA-8E1 module.
