(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 backup .
Restricted data channels do not allow the transmission of
occurrences of more than seven contiguous zero bits. See
also unrestricted data channel.
Circuit pack added to the power supply that generates a
high-voltage, 20–30 Hz signal to ring a telephone.
Cable that runs between floors in a multistory 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 m).
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.
(Supplemental Alert Adapter) Device that permits alerting
equipment to be connected to an analog multiline
telephone jack so that people working in noisy or remote
areas of a building can be alerted to incoming calls.
Telephone buttons that provide access to both inside and
