Fic-1Ct3 - H3C MSR Router Comware 5 Series Manual

FIC-1CT3

Introduction
The 1-port channelized/non channelized T3 interface module (FIC-1CT3) 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 No 64 kbps or N No 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. Through
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.
