Abstract
Abstract A telephone frame characterized in having both the connector and protector terminals on one surface thereof. The protective devices are mounted at a lower part of the frame, with connector terminals disposed thereabove. Channels are provided to facilitate the entry of cables to the opposite side of the frame to permit the very high density in the number of connectors available per square inch. Connector blocks are mounted in horizontal rows to be completely surrounded by vertical and horizontal cable and conductor-carrying troughs to facilitate the use of short length jumpers.
