Introduction
1) FIC-1E1/FIC-2E1/FIC-4E1
FIC-1E1/FIC-2E1/FIC-4E1, the 1-/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.
2) FIC-1E1-F/FIC-2E1-F/FIC-4E1-F
FIC-1E1-F/FIC-2E1-F/FIC-4E1-F, the 1-/2-/4-port fractional E1 interface module, differs from the
FIC-1E1/FIC-2E1/FIC-4E1 primarily in the sense that:
z
The FE1 operating mode supported by the E1-F modules allows only one n × 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.
z
The FIC-E1-F modules do not support PRI mode.
Interface attributes
The following table describes the interface attributes of the FIC-E1 and FIC-E1-F modules.
