(kilobits per second)
One of three modes of system operation, in which the
system uses personal lines on line buttons for outside calls,
with a separate interface ( ICOM buttons ) for inside calling.
See also Behind Switch mode and Hybrid/PBX mode.
(local area network) Arrangement of interconnected

control unit to specific buttons on each telephone.
Pattern that data assumes as it is transmitted over a
communications channel.
Adjustment for the amount of cable loss in decibels (dB),
based on the length of cable between a 100D module and

Refers to inside system lines and outside lines/trunks in
general terms. See also line and trunk .
Physical interface on a module in the control unit for
connecting an outside line/trunk to the communications
system. Also called "trunk jack."
Module on which the jacks for connecting central office
lines/trunks and/or the jacks for connecting the extensions
are located.
In a system that is part of a private network , a list of
extension ranges that the local system refers to in order to
route local intersystem calls via UDP .
In a system that is part of a private network , an extension
that is listed in the system's local dial plan .
A method for connecting an extension jack to an on-site
