Abstract: A telephone network interface device utilizing network termination modules for interconnecting telephone company wiring to the wiring of respective subscribers incorporates an improved organization of elements to reduce the cost of such elements; to facilitate their use; and to improve the flexibility and compactness of the organization. The device incorporates an improved hinge arrangement for use with the internal security closure that permits ready removal of the closure to facilitate servicing the installed equipment. A novel ground bus organization comprising an assemblage of bus sections of uniform length arranged to accommodate the length of stack of network termination modules housed in the device reduces the variety of ground buses required to accommodate module stacks of various size.

Abstract: The present invention involves a one-sided modular distributing frame assembly for distributing telephone circuits and particularly adapted for wall mounting. It includes a terminal block bay member which is a generally vertical hollow member with forward and rear surfaces. The forward surface has a plurality of alternating terminal blocks and interstices. Each terminal block communicates with the rear surface and provides appearances for subscriber or office cables. The rear surface is adapted for mounting adjacent a supporting surface. The frame also includes an outside plant bay member which is a generally vertical hollow member with forward and rear surfaces. The forward surface mounts a plurality of connector blocks which provide termination for subscriber cables. The rear surface is adapted for mounting adjacent a supporting surface.

Abstract: A station protector for communication lines includes a line terminal formed for electrical connection to the communication lines and affixed to a base member of electrical insulator material. The base member has a well into which an arrester cartridge can be threaded. There is a grounding element affixed to the base member, the grounding element including an extending grounding member located outside the area of the well. A spring electrically connects the line terminal to a surge voltage arrester if an arrester cartridge is properly positioned in the well, and grounds the line terminal in the absence of the arrester cartridge or any part thereof.

Abstract: The present invention involves a modular distributing frame assembly for distributing telephone circuits. It includes a central office bay member which has a generally vertical hollow member with forward and rear surfaces. The forward surface has a plurality of alternating terminal blocks and interstices. Each terminal block communicates with the rear surface and provides appearances for office cables. The rear surface defines a vertical opening adapted to receive the office cables. The frame also includes an outside plant bay member with a generally vertical hollow member with forward and rear surfaces. The forward surface has a plurality of alternate terminal blocks and interstices. Each of the terminal blocks provides appearances for subscriber cables. The rear surface defines a vertical opening with a plurality of connector blocks mounted therein.

Abstract: A station protector for communication lines includes an electrical conductor formed for connection to the communications lines and affixed to a base member, a grounding means affixed to the base member, an arrester cartridge disposed in an aperture in the base member and a biased resilient member electrically coupling the electrical conductor to a surge voltage arrester or to circuit ground in the absence of the arrester.

Abstract: A surge voltage arrester assembly for protection of communications lines from over voltage and excess current conditions includes a sealed cold cathode gas tube forming a primary arc gap and disposed within a cage member with an insulator member disposed between the gas tube and an electrical conductor forming a secondary arc gap sealed from contaminants, in parallel with the primary arc gap and affixed onto a cylindrical conductor by a retainer means.
