(Global) Analog Station media bay module (ASM8+)

The (Global) Analog Station media bay module (ASM8+) provides the same functionality as the ASM8 with the addition of the following features:

•support for calling line identification pass-through

•the option to activate disconnect supervision at the device

•the ability to pass a voice mail message indicator signal to activate a message waiting lamp on the telephone, if it has one

•support for an Off Premise Extension (OPX).

For this release, this module is supported in the North American and UK profiles, only.

The ASM8+ has one amphenol connector on the faceplate. For details about wiring the ASM8+, refer to Chapter 10, “Wiring the modules,” on page 131.

Ringer Equivalency (REN) for each module is 2 (two).

NOTE: The termination on the analog interface may consist of any combination of devices subject only to the requirement that the sum of the RENs of all the devices does not exceed the REN of the interface to which the device is connected. The ringer equivalency number, per port, for this module, is 1 (one).

The back of the ASM8+ has two sets of DIP switches. The first set defines the DS30 bus and offset. The second set determines if the module allows an automatic firmware download from the system (BCM 3.6 software) or which country firmware the module will use. Refer to Chapter 7, “Setting media bay module DIP switches,” on page 83.
