Introduction
The 1-port channelized T3 interface module (MIM-1CT3) serves to:
•
Transmit/Receive and handle one channel of T3 fast traffic, as well as provide the accessing of
T3 traffic when working in T3 mode.
•
Provide the low-speed accessing service at the speed of n No 64 kbps or 56 kbps, where n is
smaller than or equal to 128, when working in CT3 mode.
NOTE:
T3 represents the tertiary group rate of T system in the TDM system, that is, 44.736 Mbps. A T3
channel can be channelized into 28 T1 lines through the demultiplexing processes of T23 and T12,
each T1 line also supporting the operating modes 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.
