ABSTRACT:
A data communications system which comprises at least one group of subscriber data interface elements, with each interface element having at least one data input port and a data output port, and each output port being electrically connectable to a subscriber line of the telephone network to transmit data thereon without interfering with any telephone service that may be present on these subscriber line. A network data interface element, for each group of subscriber data interface elements, being located within a short distance from the farthest subscriber data interface element. Each subscriber data interface element having a data input port and a data output port, and each input port being electrically connectable to a subscriber line of the telephone network and in communication with these subscriber data interface elements thereover. A data collection unit having a data storage mechanism and a plurality of data input ports, with each data input port being connectable to the data output port of a corresponding network data interface element and capable of communicating therewith for collecting and storing the data received from these network data interface elements and assembling the data into a data frame. A data communications network for carrying the data frames produced by the data collection unit to at least one data processing facility.
