Connecting the interface cable

Step1 Choose a 4E1/8E1 conversion cable appropriate to the interface type of the peer device to be

connected.

z

If the interface impedance of the peer device is 75 ohm, use a 75-ohm 4E1/8E1 conversion cable.

z

If the interface impedance of the peer device is 120 ohm, use a 120-ohm 4E1/8E1 conversion
cable.

Step2 Insert the DB-68 connector at one end of the 4E1/8E1 conversion cable to the DB-68 port on the

FIC-IMA-4E1/FIC-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 behavior of the LINK LED for the slot on the module panel: OFF

means the line has problem and signal is out of synchronization. Check the link status.

FIC-IMA-4T1/FIC-IMA-8T1

Introduction

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