Step4 Connect the E1 cable to another device, by reference to the previous subsection.
Step5 Power on the router, and check the behavior of the LINK LED on the module panel: OFF means fault
occurs on the line and the signal is not synchronized. Check the line status.
FIC-8E1/FIC-8E1-F
Introduction
1) FIC-8E1
FIC-8E1, the 8-port channelized E1/PRI interface module, transmits, receives, and processes eight
channels of E1 data traffic. In addition, you can use the module for other purposes, such as CE1 access
and the ISDN PRI function.
2) FIC-8E1-F
FIC-8E1-F, the 8-port fractional E1 interface module, is different from the FIC-8E1 interface module in
the sense that:
z
The FE1 operating mode supported by the FIC-8E1-F module allows only one n × 64 kbps bundle
to be formed on each interface, where n = 1 to 31. However, a FIC-8E1 module allows arbitrary
grouping of 31 channels and therefore multiple bundles.
z
The FIC-8E1-F module does not support PRI mode.
Given a FIC-8E1 module, the system automatically creates a serial interface for each timeslot bundle
formed on a controller E1 interface.

The following table describes the interface attributes of the FIC-8E1/FIC-8E1-F modules.
