Quidway® AR 28 Router T1 Interface Module

Quidway® AR 28 Router T1 Interface Module

Overview

AR28 router supports three channelized CT1/PRI modules, 1T1, 2T1 and 4T1, and three
non-channelized T1 modules, 1T1-F, 2T1-F and 4T1-F.

1T1/2T1/4T1 is the abbreviation of 1-/2-/4-port channelized CT1/PRI interface module. The major
function of T1 module is to transmit T1 data flow and provide the CT1 access. It can realize the
ISDN RPI function and the purpose of one board multi-use.

1T1-F/2T1-F/4T1-F is the abbreviation of 1-/2-/4-port non-channelized T1 module. Where, F
indicates fractional T1. The main differences between the 1CT1/2CT1/4CT1 and
1T1-F/2T1-F/4T1-F are:

The FT1 working mode supported by T1-F module can be bound once (bound as a channel;
the rate is n × 64 K or 56 K, n=1-24). The CT1 module can group the 24 channels rand omly to
realize binding for many times.
