A cartridge that allows add-on modules to be connected to the
Controller through fiber cables. There are two versions available, a
2-port and a 6-port Expansion Cartridge. Up to two Expansion
Cartridges can be installed in the Controller.
A passive radio frequency emitter connected to a Base Station radio.
There are both omni-directional and directional external antennas
for use with the Companion system. An external antenna can be used
instead of the internal Base Station antenna to extend radio coverage
to hard-to-reach places or locations where Base Stations cannot be
installed.
A sequence of numbers used to activate a Configuration or
Administration session or a feature such as contrast adjustment on
the Administration Terminal.
A hand-off occurs when an active radio link to a portable is
transferred from one Base Station to another Base Station in the
Companion system (that is when the user moves from one cell to
another). Hand-off occurs automatically when the Controller detects
that the strength and quality of the radio signal have gone below a
predefined threshold.
Either a Private Branch Exchange (PBX) or a Public Switched
Telephone Network (PSTN) system to which the Companion system
provides a wireless service layer.
Host delay is a configuration setting that controls how long the
system waits after selecting an access line for an outgoing call before
transmitting the dialed telephone number on that access line. This
delay ensures that a dial tone is present before the dialed telephone
number is transmitted. The installer programs host delay according
to the requirements of the host switch.
