Abstract: A fuse holder adapter for use with knife-blade fuse clips used with standard 600 ampere fuses in which the adapter comprises first and second metallic plates mounted in facing, spaced relationship on an insulator plate. The first and second metallic plates have respective first and third sections which are adapted to receive fuse clips to form fuse holders of different length and further have respective second and fourth sections formed as knife-blades and extending beyond the insulator plate so as to be able to be receivable in the knife-blade fuse clips used with the standard 600 ampere fuses.

Abstract: An access and test apparatus for subscriber and central office cable pairs connected to associated socket pairs in a main frame in which the apparatus includes a body member and pairs of connecting terminals extending from the body member for receipt in the socket pairs and first and second switch means in the body member for selectively interconnecting the connecting terminals and, therefore, sockets and cable pairs to first and second access terminals, as well as to selectively provide short circuit and open circuit conditions to the connecting terminals and, hence, sockets and cable pairs.

Abstract: A circuit and method for enabling the automatic testing of trunks leading to automatic call distributors from a remote testing location is disclosed. In accordance with the invention, when the remote testing location wishes to test a trunk leading to an automatic call distributor, tones are generated which enable the remote testing location to be connected to a test line of the automatic call distributor rather than to an operator position.

Abstract: A telephone pay station wherein a disconnect circuit is provided for disconnecting the pay station from the central office in response to the coin collect signal generated at the central office.

Abstract: In a packet switched multiplexed data/voice communication system, timed loopbacks along a subscriber line are effected by purposely extinguishing or killing the DATA carrier sewing the line.

Abstract: A bridging connector for use in a telephone central office wherein the connector body has first and second rows of sockets on a first face and first and second rows of wire wrap terminals on a second face, the terminals being electrically connected to the sockets, and wherein a PC card is mounted on the body so that the wire wrap pins pass through first and second rows of apertures, these apertures being electrically connected to corresponding rows of holes through which extend first and second rows of connecting pins.
