use by any local channel module passes through as before. You can use a receive-only channel
module to monitor a channel passing through without affecting its passage.
2.1.3 CM-5RB Common Modules
The CM-5RB common module, the core building blocks of ACS-160 and STL-160 Series multiplexers,
provides one full-duplex T1 port. The ACS-163 or ACS-167 terminal multiplexer has one CM-5RB
module. The ACS-166 or ACS-169 dual terminal multiplexer, or the ACS-165 or ACS-168 drop and
insert multiplexer, has two CM-5RB modules.
The CM-5RB module provides these basic operational functions:
● Channel multiplexing to form the T1 aggregate
● T1 line driver (output)
● Transmit timing functions
● T1 line receiver (input)
● T1 aggregate demultiplexing to individual channels
● Loopback configurations
● Microprocessor control
● User interface
Figure 2-4 shows a functional diagram of the CM-5RB module.
