8.13 RT-FIC-1CT3
8.13.1 Introduction
The main functions of RT-FIC-1CT3 include:
Working in T3 mode, the card can transmit/receive and process the fast traffic of
one T3 channel, as well as provide the accessing of T3 traffic.
Working in CT3 mode, the card can provide the subscribers with the low-speed
accessing service at the speed of Nx64kbps, given N is smaller than or equal to
128.
Note:
T3 represents the tertiary group rate of T system in the TDM system, that is, 44.736Mbps.Through the
demultiplexing processes of T23 and T12A, a T3 channel can be channelized into 28 T1 lines, each also
supporting the operating mode of CT1. T23 is used to indicate either T2-to-T3 multiplex or T3-to-T2
demultiplex, and T12 to indicate T1-to-T2 multiplex or T2-to-T1 demultiplex. “T23” and “T12” discussed
here represent the demultiplex process.
