Abstract
Disclosed is an adaptive multijunction unit apparatus for multiplexing data streams between a master computer and a plurality of slave computers coupled through telephone system communication lines. The apparatus receives and processes both user data and network data which can include commands instructing the apparatus to change the operating modes of its various circuit components. For example, the adaptive multijunction unit apparatus can respond to commands to raise or lower its data transmission rate or to switch between dual channel and single channel data transmission. The apparatus includes a splitter/combiner function which copies data received from the master computer, onto output ports directed to multiple slave computers.
