| | Multidrop data concentrator communication network - Patent 4726017 |
 | | A multidrop network for effecting communications between a master site and a plurality of remote slave sites employs a multiport multiplexer at the master site and at slave sites, for interfacing multiple ports to a single telephone communication link. |
 | | Before describing, in detail, the particular improved multidrop concentrator communication scheme in accordance with the present invention, it should be observed that the present invention resides primarily in a novel structural combination of conventional communication and data/signal processing circuits and not in the particular detailed configurations thereof. |
 | | Thus, the block diagram illustrations of the Figures do not necessarily represent the mechanical structural arrangement of the exemplary system, but are primarily intended to illustrate the major structural components of the system in a convenient functional grouping, whereby the present invention can be more readily understood. |
