Nortel BCM 32 Digital Extension Media Bay

Digital station media bay module

The digital station media bay modules (DSM) support digital telephones on the BCM system. This section describes the DSM16(+) and DSM32(+) MBMs

The DSMs have the following characteristics:

• DSM16(+) — supports 16 digital telephones through one RJ-21 connector. Set the double density switch to enable the DSM to carry 16 extensions over a half DS30 bus. If required, install a second DSM16(+) and set the double density switch to occupy the second half of the DS30 bus to expand the number of extensions to 32.
• DSM32(+) — supports 32 digital telephones through two RJ-21 connectors. A DSM32(+) operating in single-density mode occupies two DS30 buses. Set the double density switch to enable the DSM to carry 32 extensions over a single DS30 bus.
