FIC-1CT3
Introduction
FIC-1CT3, the 1-port channelized/non channelized T3 interface module, delivers these functions:
In T3 mode, transmitting, receiving, and processing one channel of T3 fast traffic; providing T3
traffic access.
In CT3 mode, providing the subscribers with N x 64 kbps or N x 56 kbps low-speed access, where
N is smaller than or equal to 128.
NOTE:
T3 represents the tertiary group rate of T system in the TDM system, that is, 44.736 Mbps. Throu
g
h T23
and T12A demultiplexing, a T3 channel can be channelized into 28 T1 lines, each also supporting the
operating mode of CT1. T23 means either T2-to-T3 multiplex or T3-to-T2 demultiplex, and T12 means
T1-to-T2 multiplex or T2-to-T1 demultiplex. "T23" and "T12" discussed here represent the demultiplex
process.
