BCM200/400 4.0 Installation and Maintenance Guide
Installing an emergency telephone
You can use the emergency telephone to make calls when there is no power to the BCM system.
To install an emergency telephone on the BCM system, connect a single line analog telephone to
the auxiliary port on the CTM/GATM. When you make a call from the emergency telephone, the
auxiliary port uses the telephone line connected to the line 1 port of the CTM/GATM.
To install the emergency telephone
1 Connect a single line analog telephone to the auxiliary port on the CTM.
2 Connect an analog PSTN line cable to the line 1 port of the CTM.
Installing IP Phones
The system can be set to automatically assign DNs to the Nortel IP Phones. If you choose to
manually assign DNs, choose DNs from unused DNs in the digital range. However, port numbers
are assigned from DS30 01 (ports 0101-0132) first; then from DS30 08, if there are ports available,
and DS30 07 if the system is running a 3/5 DS30 split. If no ports are available on those DS30
blocks, the system may assign digital set port numbers. Also ensure that you do not assign DNs
that are assigned to Call Center mailboxes (CDNs).
Installing the mobility systems
The radio-based mobility systems all have their own documentation that describes the hardware
and installation and activation of the handsets.
• Digital Mobility system: The BCM main unit can support a maximum of two digital mobility
controllers (DMC), which act as the call processing unit between the BCM main unit and the
digital mobility base stations and handsets. The DMCs have a one-to-one connection with
digital ports on the BCM main unit.
For installation and configuration details, refer to the Digital Mobility Installation and
Configuration Guide.
Installing T7406 cordless systems
The T7406 cordless system consists of a base station that connects up to three digital station ports
on the BCM system, providing a radio interface for three cordless handsets. The cordless handsets
register to the base station, which transfers the call over the telephone lines connected to the
system. The handsets are configured to emulate the T7316/M7310 telephone features. This system
is most suited for small to medium-sized office environments that are set up in an open fashion.
Tip:You can connect an emergency telephone to every CTM installed on your BCM
system.
