• Requires a free media bay module
• Improved capacity over the original DSM 16 (only uses half of an internal DS30 bus)
• 16 digital extensions supporting Nortel business series terminals or ATA2
• Requires cable to present to wiring frame/patch panel

• Requires a free media bay module
• Improved capacity over older DSM32 (only uses one internal DS30 bus)
• 32 digital extensions supporting Nortel business series terminals or ATA2
• Requires cable to present to wiring frame/patch panel

This media bay module is used to connect up to 4 x ISDN2 circuits into the BCM for up to 8 channels (lines) incoming into the system, or used for delivering ISDN to a user for i.e. video conferencing or ISDN modems etc.

• Requires a free media bay module
• Supports EURO ISDN/QSIG connectivity (i.e. BT ISDN2e)
• Can be delivered to end user equipment for ISDN to the desk

This media bay module is used to connect 1 x ISDN30 circuit into the BCM for up to 30 channels (lines) incoming into the system, or networked links (i.e. MCDN/DPNSS/QSIG).

• Requires a free media bay module
• Supports EURO ISDN/DASS 2 PSTN connectivity (i.e. BT)
• Supports QSIG/MCDN/DPNSS for private networks

• The analog direct inward dialing (ADID) MBM provides an interface for four or eight analog public switched telephone network (PSTN) lines.
• The ADID MBM supports both pulse and tone dialing as well as disconnect supervision, and direct inward dialing call progress signaling as described in standard TIA-464C.
• The ADID MBM uses an RJ-21 connector for trunk connections. The ADID is available either in four-port (ADID4) or eight-port (ADID8) configurations.

• The ADID MBM uses an RJ-21 connector for trunk connections. The ADID is available either in four-port (ADID4) or eight-port (ADID8) configurations.

• 8 analogue ports
• requires 3.5 or later software (BCM 200/400)
• BCM 50/450 supported
• requires spare media bay module

• The Nortel BCM Digital Station Module 16 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
• The Nortel BCM DSM16+ is compatible with the BCM 200/400 Main Unit, BCM 400 Expansion Unit, and BCM 50 Expansion Unit
