Introduction
•
FIC-1T1/FIC-2T1/FIC-4T1
The 1-/2-/4-port channelized CT1/PRI interface module (FIC-1T1/FIC-2T1/FIC-4T1) 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.
•
FIC-1T1-F/FIC-2T1-F/FIC-4T1-F
The 1-/2-4-port fractional T1 interface module (FIC-1T1-F/FIC-2T1-F/FIC-4T1-F) differs from
the FIC-1T1/FIC-2T1/FIC-4T1 primarily in the sense that:
{
The FT1 operating mode supported by the T1-F modules allows only one n No 64 kbps or n
No 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.
{
The FIC-T1-F modules do not support PRI mode.
