60 Chapter 4 Selecting the media bay modules for your system
P0609324 01
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 8, 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.
An example for North America:
• If you require 12 digital extensions, you need one DSM 16.
• If you require 24 digital extensions, you need one DSM 32.
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 48.
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 ASM8+ can also access
these DNs.
Note: If you require only a few analog extensions, you can use a Business
Communications Manager ATA 2 to connect these devices to your DSM 16, DSM 32 or
the DSM connector on a 4X16 module. Each analog extension requires a Business
Communications Manager ATA 2.
