TERM DEFINED
Transmitter
A transmitter is an electronic device, consisting of oscillator,
modulator, and other circuits, that produce a radio or television
electromagnetic wave signal for radiation into the atmosphere by
an antenna.
Unspecified Bit
Rate
Service that operates on a connection basis and allows for raw
cell or best effort transport by the network. In this service, cells
are transported by the network whenever bandwidth is available
and traffic is presented by the user. Data using UBR service is
more apt to be discarded during peak traffic times in deference to
data using other classes of service.
Uninterruptible
Power Supply
An optional BS element used to provide power in the event of an
AC power failure.
Variable Bit Rate-
Real Time (VBR-RT)
Service that operates on a connection basis and offers very low
delay variance but requires access to a variable amount of
network bandwidth; used for such applications as packet video
and voice.
Variable Bit Rate-
Non-Real Time
(VBR-NRT)
Service that operates on both a connection and connectionless
basis and allows delay variance between the delivery of cells;
used for data applications which have potentially bursty traffic
characteristics, including LAN interconnect, CAD/CAM, and
multimedia.
Virtual Circuit
A logical connection, not a physical connection, provides multiple
connections that can be defined simultaneously across a single
network facility, with each connection having flexible bandwidth.
