ABSTRACT:
A telephone main distribution frame connector assembly in which internal hand wiring is eliminated comprises a field of terminals for terminating incoming telephone line pairs and another field for terminating inside plant equipment lines, a field of terminals for terminating incoming lines, and a plurality of spaced parallel printed circuit boards for providing connections between the two fields of terminals. A series of spaced parallel ground busses run perpendicular to the circuit boards. The circuit boards have edge regions that are straddled by line terminal pins of overvoltage arresters for protecting the lines, which arresters also have ground terminal pins that engage the grounds busses between the circuit boards. Bezels at the first mentioned fields and an adjacent test field, along with bezels at the edge regions, aid in supporting the circuit boards.
