ABSTRACT:
A modular, high density cross-connect frame specifically adapted for central office application and forming a centralized distributing frame intended for patch and cross-connect circuits for digital equipment. The frame is dual-sided, with the patching and testing administration entirely on one side confined to an area readily manually and visually accessible to service personnel, with cross-connect administration confined to the opposite side. Internal connections are made using a vertically oriented cabling plane disposed between the two sides of the frame using a relatively few number of cables each having a large number of individual connectors which interconnect a first set of connector blocks with corresponding jack frame elements. A second plurality of connector blocks is disposed immediately opposite the jack frame elements, and relatively short length connectors are required to interconnect the jack frames with the second plurality of blocks. The result of this arrangement is high space utilization, permitting much higher numbers of individual circuits to be accommodated on a frame of given dimensions.
