Description
An RJ-45 jack used to connect a computer running
administration software, such as Element Manager, to the main
unit.
RJ-45 jacks used to connect the customer LAN to the main unit.
Used to connect to the BCM450 system using a serial cable.
Two USB 2.0 ports used to connect a USB storage device (in the
bottom port only) or the data interface for an uninterruptible
power supply (UPS) to the main unit. The main unit uses the data
interface for the UPS to monitor and control the UPS functions.
You must format the USB storage device for the FAT32 file
system. If necessary, reformat the USB storage device by
plugging it into a USB port on your computer, right-clicking the
USB device icon, and selecting FAT32 reformatting. This
destroys any data on the USB.
The BCM expansion cabinet connects to the BCM450 main unit
through the DS256 jack on the faceplate. The DS256 cable to
make this connection is provided with the purchase of a BCM
expansion cabinet.
The BCM450 system 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 to directly switch the auxiliary ringer.
If 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 BCM450
system uses this jack to control the external paging amplifier.
The BCM450 system uses the page output to connect an
internally generated voice paging signal to an external paging
amplifier (customer supplied).
The BCM450 system 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.
