CM-5RB Common Modules

There is one common module in a terminal multiplexer and two common modules in a dual terminal or
drop and insert multiplexer. Each CM-5RB common module provides one T1 port. Section 1.5 – CM-
5RB User Interface gives details on this common module. For optional time delay capability, use the
CM-5R-TD module.
1.4.3

Channel Modules

There are one or more channel modules for
● Voice
● Data
● High fidelity audio
● Special applications
Each channel module may terminate one or more payload circuits (Section 2.1.6 – Channel Modules).
1.4.4

Module Adapters

All common and channel modules require module adapters, which insert directly behind each module
and provide the circuit connector(s). Every channel module works with at least one type of module
adapter, and some channel modules are compatible with several module adapters, each one providing
a different type of connector or circuit interface.
Each CM-5RB common module is normally shipped with an MA-215 module adapter. The MA-215
adapter can support module redundancy through the addition of a CA-412 cable and a second CM-5RB
module. Systems preconfigured for module and line redundancy (for example, the ACS-163R-ACC
system) come equipped with two CM-5RB modules and (one each) MA-235-1 and MA-235-2 module
adapters. MA-215 and MA-235 module adapters provide RJ-48C T1 connections with CSU capabilities.
Systems without line redundancy can be equipped with DB-15 T1 connectors by using MA-217B
module adapters.

Power Supplies

One power supply is always included, and a second one may be added in 3RU shelf systems for power
supply redundancy. (A redundant power supply cannot be installed in a 1RU shelf.) The standard
power supply for the 1RU shelf is a 30-watt, universal AC supply. There should be a minimum of 2RU
unoccupied space below this shelf. For the 3RU shelf, the standard power supply is a 60-watt,
universal AC supply, with a minimum of 2RU unoccupied space below the shelf. There are also 50-watt
DC supplies for 3RU shelves, in -48VDC -24VDC versions, which require at least a 1RU of space
between shelves.
Intraplex also produces optional 95-watt supplies for use in 3RU shelves with high power
requirements. These are also universal AC supplies and also require a minimum of 2RU of unoccupied
space below the shelf. (The type and number of channel modules in the multiplexer determine the
power requirements. Each channel module installation and operation manual gives power requirement
details. Section 7 – "Specifications" includes a listing of Intraplex power supplies.) Figure 1-4 through
1-15 show the physical placement of the ACS-160 components in the equipment shelf.
