A type of data station that includes an ISDN terminal
adapter as its DCE. It may also include an MLX telephone
for simultaneous voice and data (ISDN terminal adapter
data-only station). These data stations connect to MLX
extension jack modules for digital transmission of data over
a DS1 facility.
Physical connection point to the system for a telephone,
line/trunk, or other device. Also called "port."
(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
personal computers or terminals, sometimes accessing a
host computer, sometimes sharing resources such as files

synonymously with trunk .
Assignment of lines and trunks connected to the system
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
a channel service unit ( CSU ) or other far-end connection
point.
Refers to inside system lines and outside lines/trunks in
general terms. See also line and trunk .
