First jack on the first MLX or analog multiline extension
module in the control unit, that is, the extension jack with
the lowest logical ID in the system.
Individual extension number assigned to a telephone in a
system operating in Behind Switch mode . Each telephone
user has his or her own prime line and is automatically
connected to that line when he or she lifts the handset.
Module in the second slot of the control unit (Slot 0, to the
right of the power supply module ). Includes the software
and memory that runs the system.
Reassignment of the system programming jack position to
any of the first five extension jacks on the first MLX module
in the control unit.
Set of conventions governing the format and timing of
message exchanges between devices, such as an MLX
telephone and the control unit.
Network that is commonly accessible for local or
long-distance calling. Also called "public switched
telephone network" or "public switched network."
(Queued Call Console) MLX-20L telephone used by a
system operator in Hybrid/PBX mode only. Used to answer
outside calls (directed to a system operator position) and
inside calls, direct inside and outside calls to an extension
or an outside telephone number, serve as a message
center, make outside calls for users with outward calling
restrictions, set up conference calls, and monitor system
operation.
(random-access memory) Computer memory in which an
individual byte or range of bytes can be addressed and
read or changed without affecting other parts of memory.
System feature that allows an outside caller to gain access
to the system, almost as if at a system extension.
Procedure whereby saved and archived system
programming is reinstated on the system, from a floppy
disk or memory card . See also backup .
Circuit pack added to the power supply that generates a
high-voltage, 20–30 Hz signal to ring a telephone.
Physical interface, specified by the Electronics Industries
Association (EIA), that transmits and receives
asynchronous data at distances of up to 50 feet (15 m).
