MIM-1CT3
Introduction
The 1-port channelized T3 interface module (MIM-1CT3) provides the following features:
• Transmits and receives and handles one channel of T3 fast traffic, and provides access to T3
traffic when operating in T3 mode
• Provides low-speed accessing service at n × 64 kbps or 56 kbps when operating in CT3 mode.
n is smaller than or equal to 128.
T3 represents the tertiary group rate
(44.736 Mbps)
of T system in the TDM system. A T3 channel
can be channelized into 28 T1 lines through the demultiplexing processes of T23 and T12
. E
s the operating modes of CT1. T23 is used to indicate either T2-to-
-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.
