Step 3: Power on the router, and check the behavior of the LINK LED on the card
panel: OFF means fault occurs on the line. Check the line status.
FIC-8T1/FIC-8T1-F
Introduction FIC-8T1
FIC-8T1, the 8-port channelized T1/PRI interface card, transmits, receives, and
processes eight channels of T1 data traffic. In addition, you can use the card for
other purposes, such as CT1 access and the ISDN PRI function.
FIC-8T1-F
FIC-8T1-F, the 8-port fractional T1 interface card, is different from the FIC-8T1 card
in the sense that:
■ The FT1 operating mode supported by the FIC-8T1-F card allows only one n ×
64 kbps or n × 56 kbps bundle to be formed on each interface, where n = 1 to
24. However, the FIC-8T1 card allows arbitrary grouping of 24 channels and
therefore multiple bundles.
■ The FIC-8T1-F card does not support PRI mode.
n
Given a FIC-8T1 card, the system automatically creates a serial interface for each
timeslot bundle formed on a controller T1 interface.
