Description of System Features
Automatic Redial (Of Busy
Number Or Unanswered Call)
Refer to the discussion titled Redialing.
Automatic Station Relocation
With this feature, the system will automatically
recognize a particular station should that station be
relocated to a new station port. When someone
places a telephone at a new port location, it will
continue to provide the same class of service
parameters and respond to the same extension
numbers as it did at the original station port. A
programmer must enable this system feature using
system class of service programming. As an added
feature when someone plugs an LCD speakerphone in
a new station port, the system will prompt the user on
the display to verify the relocation of features.
Auxiliary Equipment Interface
An installer can use the auxiliary equipment interface
to connect a telephone device or a data device to an
outside line ahead of the common equipment. The
system can detect an off-hook condition in a device
that an installer has connected to the auxiliary
equipment interface, and turn on the status light for
that line at telephones that have that line appearance.
It does this to indicate that the line is busy and not
available for station use. Auxiliary equipment interface
connections provide connections to lines 2 and 4. A
user cannot interrupt an external device by pressing
the line button unless the line has been programmed
to be non-private.
Auxiliary Ringer Interface
Refer to the discussion titled Ringing.
Background Music
Refer to the discussion titled Music features.
Basic Key Service (1 A2) Emulation
The system provides all of the basic, lA2-type, key
service features. These features are: selective line
pickup, common line pickup, multiline pickup, and
hold. No special class of service programming is
required.
Battery Back-Up
Battery Back-Up (Chassis, Cable, And Batteries)
The manufacturer offers battery back-up assemblies
including chassis, cable, fuses, and batteries as
optional kits available through normal distribution
channels. The assemblies are designed so that
installers can connect them directly to the
uninterruptable power source (UPS) interface located
on~the-common equipment chassis. The system does
not require any action from the telephone user to
make it operate on battery power nor does it require
any class of service programming action on the
programmer’s part.
Battery Back-Up Interface
The common equipment cabinet provides an interface
for an optional battery back-up kit to give full
uninterrupted system power in case of an AC power
loss. The switching and charge circuitry are in the
common equipment, while the batteries, chassis, and
cable are packaged as a separate option. When
plugged into an active AC power source the common
equipment will constantly charge the attached
batteries. Built-in circuitry automatically switches to
battery power when AC power is lost. With batteries
at full charge, a fully loaded system will operate for a
minimum of one hour without AC power.
