Quality Protection Plan Change Notice
quadrant
A group of six contiguous DS0s in fixed locations on an ISDN-PRI facility. The term comes from T1 terminology, where
quadrant means one-fourth of a T1, but an E1 ISDN-PRI facility (30B + D) has five quadrants. See also
level n (DS-n).
Quality of Service (QoS)
The measurement of transmission rates, error rates, and other characteristics to define the quality of the service that is
provided to telephone subscribers or users of a network. QoS is of particular concern for the continuous transmission of
high-bandwidth video and multimedia information. Transmitting this kind of content dependably is difficult in public
networks using ordinary best-effort protocols.
queue
An ordered sequence of calls that are waiting to be processed.
queuing
The process of holding calls in order of arrival to await connection to an attendant, an answering group, or an idle trunk.
Calls that are in a queue are automatically connected in a first-in, first-out sequence.

random access memory (RAM)
A storage arrangement in which information is retrieved at a speed that is independent of the location of the stored
dynamic random access memory (DRAM)
information. See also

RC
Radio controller
RCL
Restricted call list
RDI
Remote defect indication
real-time operating system (RTOS)
A computer architecture in which the system responds to input immediately. RTOS computers are used for such tasks as
navigation, in which the computer must react to a steady flow of new information without interruption. Most general-
purpose operating systems are not real-time because they can take a few seconds, or even minutes, to react.
Real Time Transfer Protocol (RTP)
An Internet Engineering Task Force (IETF) protocol (RFC 1889) that addresses the problems that occur when video and
other exchanges with real-time properties are delivered over local area networks (LANs) that are designed for data. RTP
gives higher priority to video and other real-time interactive exchanges than to connectionless data.
recall dial tone
A tone that the system delivers when the system completes a function such as holding a call, and is ready to accept
dialing.
