Selecting station MBMs

The number and type of telephones and related equipment you have determines which station

MBMs you require.

To select station MBMs

1 In Table 26, record the number of each type of extension you have.

2 Use the number of extensions and the number of extensions per MBM to determine how many

MBMs you need.

For example, in North America:

• If you require 12 digital extensions, you need 1 DSM16/DSM16+

• If you require 24 digital extensions, you need 1 DSM32/DSM32+

Note: If you are adding any extensions in the near future, include them in your

calculations.

Analog extensions GASM8 8 _____ GASM8

Specialty modules

Digital extensions are digital or IP telephones. You do not need to include IP telephones when calculating the number

of required DSM MBMs. For a list of the telephones that can be used with the BCM system, refer to “Telephones and

adapters” on page 72.

Analog extensions include single-line telephones, fax machines, and modems.

Note: If you require only a few analog extensions, you can use an ATA 2 to connect these

devices to your DSM16(+), DSM32(+), or the DSM connector on a 4x16 MBM. Each

analog extension requires an ATA 2.
