Abstract: An adapter for providing electrical access to individual circuits of a telephone circuit cable head is disclosed. The adapter has an elongated rectangular housing and is intended for placement between rows of receptacles of the cable head and protective plugs that mate with the cable head. Five sets of pins and sockets per receptacle are supported by the housing, with the pins for each set extending downward from a lower planar surface for engagement with sockets of the cable head and sockets for each set extending inward from an upper planar surface. Three sets of pins and sockets for each receptacle are connected to one another, providing uninterrupted electrical contact. The other two, coupled to tip and ring wires, are interrupted by a gap leaving pin and socket ends within the housing. These ends have wires joined to them, the wires extending outward for connection to test equipment. The wires in turn are coupled to a connector half for use with computerized test equipment.
