Chapter 4 Selecting the media bay modules for your system 61
Installation and Maintenance Guide
An example:
If you require 24 T1 digital lines, you need one DTM because a single DTM can handle 24
T1 lines (North America).
If you require two analog lines and 24 T1 digital lines, you need one CTM and one DTM.
Selecting the station media bay modules
The number and type of telephones and related equipment you have determines which station
media bay modules you require.
1 In Table 9, record the number of each type of extension you have.
2 Use the number of extensions and the number of extensions per module to determine how
many modules you need.
Note: Although the DTM supports several types of digital lines, you cannot connect
different types of lines to the same DTM.
You can add a maximum of three DTMs to your Business Communications Manager
system, and only on the BCM1000.
Tip: The BCM1000 can hold three media bay modules. If you require more than three
modules, a BCM1000e can be connected to support an additional six additional modules.
Note: If you are adding any extensions in the near future, include them in your
calculations.

Digital extensions are digital or IP telephones. For a list of the telephones that can be used with the
Business Communications Manager system, refer to “Telephones and adapters” on page 50.
Analog extensions include single line telephones, fax machines, and modems.
Double density: On systems running BCM 3.0 and newer software the DSM16+ and the DSM32+ can be
configured to access the lower level of DNs on each DS30 offset. The ASM8 and GASM8 can also access
these DNs.
