FIC-8E1

Introduction

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.

NOTE:

Given a FIC-8E1 module, the system automatically creates a serial interface for each timeslot bundle

formed on a controller E1 interface.
