• In CT3 mode, provides the subscribers with N × 64 kbps or N × 56 kbps low-speed access,
where N is smaller than or equal to 128.
NOTE:
T3 represents the tertiary group rate
(44.736 Mbps) of T system in the TDM system. Through T23
and T12A demultiplexing, a T3 channel can be channelized into 28 T1 lines
. Each line supports
the
operat
ing 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.
