BCM50 expansion unit and media bay modules

You can expand BCM50 trunk and station capacity by connecting up to two external BCM50 expansion units. Expansion ports on the BCM50 are enabled through keycodes.

The expansion unit fits easily with the BCM50 and is easy to integrate and install using the wallmount and rackmount accessories. The expansion unit is connected to the BCM50 using an RJ-45 CAT5 cable and uses its own external power supply, both of which are provided with the expansion unit.

Each expansion unit is capable of supporting one Media Bay Module (MBM), the same products that are used in the other products of the BCM product portfolio. BCM50 supports these Media Bay Modules:

•4x16 Combo (4 analog trunks, 16 digital stations) — North America only

•8x16 combo (8 analog trunks, 16 digital stations)

•ADID4 and ADID8 modules — North America only

•ASM8+ (8-port analog station interface) — North America only

•CTM4 (4-port CLID trunk module) — North America only

•CTM8 (8-port CLID trunk module) — North America only

•DTM (digital trunk module)

•BRI (ISDN Basic Rate trunk module)

•DSM16+ (16-port digital station module)

•DSM32+ (32-port digital station module)

•GATM4 (4-port global analog trunk module)

•GATM8 (8-port global analog trunk module)
