60Chapter 4 Selecting the media bay modules for your system

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.

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

1In Table 8, record the number of each type of extension you have.

2Use the number of extensions and the number of extensions per module to determine how many modules you need.

Table 8 Station media bay modules required

			Number of
	Number of	Type of media bay	extensions	Number of
Type of extension	extensions	module	per module	modules required
Digital extensions		DSM 16/DSM16+	16	_____ DSM 16/
				DSM16+
Digital extensions		DSM 32/DSM32+	32	_____ DSM 32/
				DSM32+
Digital extensions		4X16	16	_____ DSM 16
Analog extensions		ASM 8/ASM8+	8	_____ ASM 8/
				ASM8+

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.

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 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.
