StatMUX ==>
statistical time division multiplexing
<communications> (STDM, StatMUX) A system developed to overcome some
inefficiencies of standard time division multiplexing, where time slices are
still allocated to channels, even if they have no information to transmit.
STDM uses a variable time slot length and by allowing channels to vie for any
free slot space. It employs a buffer memory which temporarily stores the data
during periods of peak traffic. This scheme allows STDM to waste no high-speed
line time with inactive channels. STDM requires each transmission to carry
identification information (i.e. a channel identifier). To reduce the cost of
this overhead, a number of characters for each channel are grouped together for
transmission.
