Glossary
	Page GL-19
MLX telephone	A multiline button telephone that transmits and receives
	digital signals.
mode codes	Streams of touch-tone codes used by voice messaging
	applications to communicate with the system’s control unit.
modem	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.
modem data	A type of data station that includes a modem as its DCE. It
station	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.
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 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.
monitored	Extension for which one or more CTI applications is
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 CTI link and
	unmonitored extension.
Multi-Function	See MFM.
Module
multiline	An analog or digital (MLX) telephone that provides multiple
telephone	line buttons for making or receiving calls or programming
	features.
multiplexing	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.
