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, to direct inside and outside calls to an
extension or to an outside telephone number, to serve as a
message center, to make outside calls for users with
outward calling restrictions, to set up conference calls, and
to 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.
See ROM .
System feature that allows an outside caller to gain access
to the system, almost as if at a system extension. In a
private network , remote access settings are used to control
calls routed via ARS or UDP routing across the network.
Procedure whereby saved and archived system
programming is reinstated on the system, from a floppy
disk or memory card . See also
Channels that do not allow the transmission of occurrences
of more than seven contiguous zero bits. See also
Unrestricted Data Channels
Circuit pack added to the power supply that generates a
high-voltage, 20–30 Hz signal to ring a telephone.
Through centralized programming, T/R ports (including the
T/R ports on the new ETR modules) can be programmed to
accept rotary-dial and touch-tone digits or just touch-tone
digits. Available in Release 7.0 and later systems.
Cable that runs between floors in a multi-story building and
connects wiring closets.
Physical interface, specified by the Electronics Industries
Association (EIA), that transmits and receives
asynchronous data at distances of up to 50 feet
(15 meters).
Signaling in which the least significant bit of every sixth
frame per channel is used for signaling in that channel.
Read-Only Memory . Computer memory that can be read,
but cannot be changed.
