Specialized media bay modules

This section describes the modules that perform a specific job outside of the trunk and station description. Refer to Table 6.

•The DECT (Digital Enhanced Cordless Telecommunications) module allows you to add radio-based cordless communication devices to your Business Communications Manager in areas where the DECT technology is available.

•The Fiber Expansion module (FEM), provides a fast way of upgrading from an existing Norstar system simply by plugging in Norstar expansion modules to the FEM box.

DECT media bay module

(region-specific application)

Like the 4X16 module, the DECT module is both a trunk and station module. The DECT media bay module has eight RJ45 jacks that connect to base stations deployed around the coverage area. It also supports four ISDN lines, which allow a maximum of eight simultaneous call paths. This module has a wizard that sets up the module programming to match with the Business Communications Manager programming for the handsets. Refer to the DECT Installation and Maintenance Guide for specific procedures to install the base stations, to set up the DECT module firmware, and to subscribe the handsets to the Business Communications Manager.

Figure 22 shows a front view of the module. As well as a Power and Status LED, the DECT module has LEDs that indicate the Run state and base station power state.
