Abstract: An electrical transition switching apparatus and method for permitting transition switching of subscriber lines from earlier generation switching system units such as panel, crossbar and step-by-step to similar generation systems or to new generation systems such as the new electronic switching system units (E.S.S.), comprising cut through relay members, power distribution members and relay actuation means for selectively actuating and deactuating said relay members to thereby permit reversible connection of the subscribers lines to either of the similar generation units and the new E.S.S. units or to the earlier generation units to which they were originally connected.

Abstract: A line voltage surge protection device for telephone systems which normally include means for grounding excessive currents caused by strokes of lightening and the like. The device includes a gaseous discharge element which becomes conductive when the voltage in the line being protected momentarily exceeds a predetermined value to conduct current to a source of ground potential. A temperature sensitive element which operates upon the presence of a prolonged current serves to short the gaseous discharge element whereby the surge is conducted directly to ground potential. The temperature sensitive element includes means resiliently biasing the gaseous element for movement in a direction serving to short the same. A soldered retaining means opposes such movement, and heat developed in a coil in series with the line to be protected melts the solder permitting the shorting action to occur.

Abstract: Card programable line verification tester apparatus iteratively and automatically establishes connections via old and replacement (e.g., ESS) switching apparatus to subscriber loop appearances on a main distributing frame. The assumed continuous tip and ring conduction paths are then tested for faults such as spurious battery, or short, open, high impedance or crossed connections.

Abstract: A connector block assembly for connecting closely spaced wired on which high frequency signals are present, contains pairs of spring finger connectors with electrically conductive shields between different pairs. Ground contacts are arranged to be engaged by an insert module in advance of its engagement with the spring fingers and a detents and projection arrangement serves to hold the insert module at different operating positions.

Abstract: A hand-held tool for the convenient attachment and disconnection of conductors to individual insulation displacement terminals on a telephone connector block. The device includes a first member for serially inserting the free end of a conductor into a resiliently expandable slot in the terminal, and severing the end of the wire which projects from the slot at a predetermined length. A second remotely positioned member provides for the engagement of the conductor for removal of an unwanted connection. The last-mentioned member also includes structure for the engagement of a protector module overlying the terminal for purposes of removal of the same to gain access to the conductor.

Abstract: An improved telephone modular distributing frame is disclosed. The frame is particularly adapted for use with relatively large connector blocks in conjunction with relatively smaller protector blocks with provision made for maximum space utilization, ease of installation, and ready availability of the protector blocks after installation. The frame is double sided, and is characterized in the spacing of the connector blocks upon a greater area on one side of the frame, and a relatively lesser centrally located area on the opposite side of the frame where the protector blocks are located.
