multiappearance telephone
A telephone that is equipped with several call-appearance buttons for the same extension,.With a multiappearance
telephone, a user can handle more than one call on that same extension at the same time.
Multifrequency Compelled Release 2 signaling (MFC R2)
A method of signaling in which a signal consists of two frequency components. With MFC R2 signaling, a switch that
transmits a signal receives a second signal that acknowledges the transmitted signal. MFC R2 signaling is used in the US
and other countries.
multiplexer
A device that combines several individual channels into a single common bit stream for transmission. See also
multiplexing.
multiplexing
A process that divides a transmission facility into two or more channels. Multiplexing either splits the frequency band
into two or more narrower bands, or divides the transmission channel into successive time slots. See also
multiplexer;
time-division multiplexing (TDM).
multipoint control unit (MCU)
A bridging device or a switching device that is used to support multipoint video conferencing. An MCU can support 28
conference sites.
multirate

message waiting lamp (MWL).
N
N x DS0
An emerging standard for wideband calls separate from H0, H11, and H12 ISDN channels. The N x DS0 ISDN multirate
circuit mode bearer service will provide circuit-switched calls with data-rate multiples of 64 kbps up to 1536 kbps on a
T1 facility, or up to 1920 kbps on an E1 facility. In the switch, N x DS0 channels will range up to 1984 kbps using
nonfacility-associated signaling (NFAS) E1 interfaces. Also known as N x 64 kbps.
