Step4 Power on the router. Check the behavior of the LINK LED on the module panel: OFF means fault has
occurred on the line and signal is out of synchronization. Check the line status.
FIC-1T1/FIC-2T1/FIC-4T1 and FIC-1T1-F/FIC-2T1-F/FIC-4T1-F
Introduction
1) FIC-1T1/FIC-2T1/FIC-4T1
FIC-1T1/FIC-2T1/FIC-4T1, the 1-/2-/4-port channelized T1/PRI interface module, transmits, receives,
and processes T1 data traffic. In addition, you can use the module for other purposes, such as CT1
access and the ISDN PRI function.
2) FIC-1T1-F/FIC-2T1-F/FIC-4T1-F
FIC-1T1-F/FIC-2T1-F/FIC-4T1-F, the 1-/2-4-port fractional T1 interface module, differs from the
FIC-1T1/FIC-2T1/FIC-4T1 primarily in the sense that:
z
The FT1 operating mode supported by the T1-F modules allows only one n × 64 kbps or n × 56
kbps bundle to be formed on each interface, where n = 1 to 24. However, a T1 module allows
arbitrary grouping of 24 channels and multiple bundles.
z
The FIC-T1-F modules do not support PRI mode.
