Modem Pool
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
.
Module
Circuit pack in the control unit that provides the physical
jacks for connecting 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
.
Monitored
Extension

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
