FIC-2E1/FIC-4E1 and FIC-4E1-F
Introduction
• FIC-2E1/FIC-4E1
FIC-2E1/FIC-4E1, the 2-/4-port channelized E1/PRI interface module, transmits, receives, and
processes E1 data traffic. In addition, you can use the module for other purposes, such as CE1
access and the ISDN PRI function.
• FIC-4E1-F
FIC-4E1-F, the 2-/4-port fractional E1 interface module, differs from the FIC-2E1/FIC-4E1 primarily
in the sense that:
{ The FE1 operating mode supported by the E1-F modules allows only one n x 64 kbps bundle to
be formed on each interface, where n = 1 to 31. However, an E1 module allows arbitrary
grouping of 31 channels and multiple bundles.
{ The FIC-E1-F modules do not support PRI mode.
