Warning: External equipment connected to the auxiliary ringer, page relay, page output
and music on hold interfaces must use safety extra low voltage (SELV).
All four interfaces are (SELV) and the external equipment connected to these interfaces
must be SELV. If these interfaces are not SELV, you must use external line isolation units
(LIU).
The MSC faceplate offers the following optional connections.
DS256 connector— The BCM1000e connects to the BCM1000 base unit through the DS256
jack on the MSC faceplate.
The DS256 cable to make this connection is provided with the purchase of a Business
Communications Manager e1000.
Auxiliary ringer jack — The BCM1000 uses the auxiliary ringer jack to control the cadence
of an auxiliary ringer (customer supplied). You must use this output in a low current, low
voltage application only. Do not use this output for switching the auxiliary ringer directly.
Page relay jack — When you use the page signal output jack to connect an external paging
amplifier, you also use the page relay jack. The page relay jack connects a floating relay
contact pair. The BCM1000 uses this jack to control the external paging amplifier.
Page output jack — The BCM1000 uses the page output to connect an internally-generated
voice paging signal to an external paging amplifier (customer supplied).
Music on hold jack — The BCM1000 uses the Music on hold input to connect an external
music source that supplies a signal to held lines (music on hold) or telephone speakers
(background music). The input source can be any available radio or music source approved for
connection to the network.
For directions on setting up these features, refer to

MSC IP call processing hardware

If your system requires a high volume of IP telephones and/or more VoIP trunks you can adjust
your system to accommodate them. You have the option to switch DS30 bus 07 on the MSC. By
switching the bus from servicing a media bay module (the default), the system provides the
increased digital processing service to support your IP requirements.
DS30 buses are internal communication paths controlled by the MSC. Each DS30 bus
provides a possible 32 signaling channels (B1 and B2) and 32 media channels. In BCM 3.0
software, the B2 channels were reconfigured as B1 channels for station modules. As a result,
DS30 02 to 05 were configured to support 32 telephones on each bus configured with
DSM16+, DSM32+ modules set to double density. The ASM 8 module could also be
supported on all four offsets as of that software release. DS30 06 and 07 were not configured
for double density, so that they could continue to support Companion equipment. However,
these two buses could be converted to double density, if required by setting the system from
Partial Double Density (PDD) to Full Double Density (FDD).
