FIC-8E1/FIC-8E1-F
Introduction
•
FIC-8E1
The 8-port channelized E1/PRI interface module (FIC-8E1) 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.
•
FIC-8E1-F
The 8-port fractional E1 interface module (FIC-8E1-F) is different from the FIC-8E1 interface
module in the sense that:
{
The FE1 operating mode supported by the FIC-8E1-F module allows only one n No 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.
{
The FIC-8E1-F module does not support PRI mode.
