Abstract: A subscriber interface box generally shown at comprises a network section and a subscriber section, the network section connected to a network cable and the subscriber section connected to subscriber cables and whereby the network and subscriber sections are electrically connected via a test socket. The subscriber interface box comprises lever members having cavities therethrough for receiving wires of the cables such that the wires can be rapidly connected and disconnected to insulation displacement contacts. The latter is done by placing the wires in corresponding holes of the lever members when the lever members are in an open position, whereby the lever members comprise slots transversely intersecting the wire receiving cavities. The slots for receiving upstanding insulation displacement contacts such that when the levers are pushed down to a close position the wires are forced into electrical contact with the IDC contact slots.
