statistical time division multiplexers
   (STDM)
   Characterized as variable allocation systems that share the resources of the digital high-speed link with the terminal devices on an as-needed basis; STDMs operate on the premise that communications links between computers and terminals are rarely utilized 100 percent of the time; STDMs use real-time statistics to allocate capacity on the high-speed link only to those terminals that are actively sending information.
