Media bay module combinations
This section describes s ome combina tions of trunk and station modules to demonstrate how t o fit
the module s int o the DS30 bus resou rce s. These c onfigura tions are meant to he lp demonstr ate how
your system ca n be confi gured using the information in this guide and do not necessa rily reflec t
real-life configurations.
Combining CTM s/GATMs an d 4X16 s
The 4X16 combination media bay module is a combination of a CTM or GATM and a DSM. A
maximum of four CTMs/GATMs can fit into a DS30 bus, when each is given a different offset.
Therefore, you can combine a maximum of three GATMs with a 4X16 combination module. This
configuration would occupy two full DS30 bus blocks.
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. Table 1 demonstrates this
configuration of CTMs/GATMs and 4X16 modules, including the switc h settings for each module .
