A networking system to interconnect computer terminals with a host computer, the system being capable of carrying data bits at high frequencies and being capable of readily having its interconnection pattern changed. The system includes a plurality of composite cables for transmission of the data bits, one such cable for each such computer terminal, each of the cables including at least two sets of twisted pair data lines and an associated drain line, each set of data lines being within a shielding sleeve, and said sleeves being isolated from one another. A distribution wiring board for interconnecting the cables with the host computer, the wiring board including a punch down block with multiple sets of aligned punch-down connectors for connecting the wires in the sets and the drain wires to the wiring board, means for grounding the drain wires, and a data board for changing the local area network formed by the cables and the computer terminals. The composite cables also includes telephone wires for providing telephone service at the computer terminals.
