4X16 media bay module
(North American systems only)
The 4X16 provides both analog trunk connections and connections to digital telephones. The
module is a combination of a CTM media bay module, with four analog lines, and a DSM
16-digital telephone media bay module. Each of the four ports supports Caller ID and disconnect
supervision. An auxiliary port beside Line 1 allows you to use an analog telephony device, such as
a modem, fax or telephone, to share the trunk. Figure 20 shows a diagram of the 4X16.
The 4X16 has one amphenol connector and five RJ11 connectors on the faceplate. For details on
the 4X16 wiring, refer to Chapter 12, “Installing Analog Terminal Adapters,” on page 149.

Analog station modules and analog devices
The Business Communications Manager supports two types of analog station media bay modules.
The system also allows you to attach analog devices to digital media bay modules by installing an
analog terminal adaptor (ATA2) between the media bay module and the telephone. Finally, the
FEM media bay module supports Norstar-based analog modules. All of these modules may have
slightly different features or capabilities.
The table below provides a quick overview of the engineering information and feature function for
each type of analog device supported by the system.
