A multiline button telephone that transmits and receives
digital signals .
Streams of touch-tone codes used by voice messaging
applications to communicate with the system's control unit.
Device that converts digital data signals to analog signals
for transmission over a telephone line, and analog signals
received on a telephone line to digital signals.
A type of data station that includes a modem as its DCE. It
may also include an MLX telephone for simultaneous voice
and data (MLX voice and modem data station), an analog
multiline telephone (analog voice and modem data
station), or a single-line telephone for dialing only (modem
data-only station). These data stations connect respectively
to MLX, analog, or tip/ring extension jack modules. They
provide analog transmission of data.
Pair, or group of pairs, of modems and data modules with
interconnected RS-232 interfaces that converts digital
signals to analog, or analog signals to digital, thereby
allowing users with ISDN terminal adapter data stations to
communicate with users who have analog modem data
stations .
Circuit pack in the control unit that provides the physical
jacks for connection of telephones and/or outside
lines/trunks to the communications system. In the name of
a module, the first digit indicates the number of line/trunk
jacks it contains; the last digit indicates the number of
extension jacks it contains. If no letters appear after the
number, a line/trunk module provides loop-start lines or an
extension jack module provides analog or tip/ring jacks. For
example, a 408 GS/LS MLX module contains four line/trunk
jacks and eight digital (MLX) extension jacks, and provides
either loop-start (LS) or ground-start (GS) trunks.
Extension for which one or more CTI applications is
receiving call information. The CTI application does not
have to be directly attached to the equipment at the
extension in order to monitor calls. The call information may
appear on the PC screen of another extension that has
been programmed to receive it. See also CTI link and
unmonitored extension.
See MFM .
An analog or digital (MLX) telephone that provides multiple
line buttons for making or receiving calls or programming
features.
The division of a transmission channel into two or more
independent channels, either by splitting the frequency
band into a number of narrower bands or by dividing the
channel into successive time slots.
