Media bay module combinations
This section describes some combinations of trunk and station modules to demonstrate how to fit
the modules into the DS30 channel resources. These configurations are meant to help demonstrate
how your system can be configured using the information in this guide and do not necessarily
reflect real-life configurations.
Combining CTMs and 4X16s
The 4X16 combination media bay module is a combination of a CTM and a DSM. A maximum of
four CTMs can fit into a DS30 channel, when each is given a different offset. Therefore, you can
combine a maximum of three CTMs with a 4X16 combination module. This configuration would
occupy two full DS30 channels.
Which means, you can install a maximum of three of these combinations in a Business
Communications Manager box with an extension box added to it.
demonstrates this
configuration of CTMs and 4X16 modules, including the switch settings for each module.
