TL;DR: In this paper, the authors describe a networking system to interconnect computer terminals with a host computer, the system being capable of carrying data bits at high frequencies and being able to readily having its interconnection pattern changed.
Abstract: 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.

19 May 2000TL;DR: In this paper, the authors proposed a connector that replaces industry standard punched down block wiring devices to eliminate the need for rewiring when changing or rerouting multiple phone lines at a given location.
Abstract: The present invention relates to relates to electrical connectors, and in particular to a connector that replaces industry standard “punch down block” wiring devices to eliminate the need for rewiring when changing or re-routing multiple phone lines at a given location. The present invention provides for the connection of edge card connectors to punch down blocks or other wire terminating devices that are permanently connected to incoming and outgoing phone lines in a unique way by the use of jumpers that eliminate the need for rewiring when changing or re-routing multiple phone lines at a given location. A key advantage is that the invention makes the re-routing operation foolproof in that access to the permanently connected wiring is no longer necessary thereby eliminating the possibility of negatively affecting the integrity of the phone network by attempting to customize the wiring connections.
