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.

Abstract: A locking device for preventing unauthorized access to a telephone subscriber circuit jack located at a building entrance terminal structure or similar face is disclosed. The jack accommodates a plug having a manually engageable release member and defines a recess accommodating the jack. The locking device includes a housing element defining a generally rectangularly enclosed recess. Means within the recess locates the plug in predetermined position. A forward wall in the housing defines an opening opposite the plug which will provide access. A cover element is supported for selective movement relative to the housing element between first and second positions, the cover element being clear of the opening in the jack in a first position and at least partially overlying the opening in a second position. Latching means is provided on the cover element and locking means on the housing element engages the latching means for preventing movement of the cover from the first position to the second position.

Abstract: A modular, high density cross-connect frame specifically adapted for central office application and forming a centralized distributing frame intended for patch and cross-connect circuits for digital equipment. The frame is dual-sided, with the patching and testing administration entirely on one side confined to an area readily manually and visually accessible to service personnel, with cross-connect administration confined to the opposite side. Internal connections are made using a vertically oriented cabling plane disposed between the two sides of the frame using a relatively few number of cables each having a large number of individual connectors which interconnect a first set of connector blocks with corresponding jack frame elements. A second plurality of connector blocks is disposed immediately opposite the jack frame elements, and relatively short length connectors are required to interconnect the jack frames with the second plurality of blocks.

Abstract: A male base subscriber pair protector module in which substantially all of the internal components thereof are assembled upon an axially elongated base element prior to insertion within a module housing, thereby facilitating manufacture and allowing the use of a wide variety of existing components which are readily adapted for such assembly.

Abstract: A high density front administered telephone protector block having three terminal connection surfaces disposed on three sides of the block. The block is mounted on an inner end by a rearwardly extending bracket. A first side surface mounts protector modules, an oppositely disposed second side surface mounts outside plant wire wrap pins for connecting subscriber pairs. A third outer end surface extends transversely past the side surface and mounts quick clip terminals for cross connections.

Abstract: The disclosure relates to an improved telephone connector block having quick clip contact element holder elements which support the contact elements in a given plane. The contact holder elements are modified so that they extend a greater distance outwardly of the quick clip terminals which they support to incorporate a conductor retaining area into which the free end of a conductor may be moved to be retained until subsequently engaged by a tool which then moves the conductor into the quick clip contact element and a corresponding strain relief area disposed immediately adjacent thereto in the respective contact holder element.

Abstract: A moulded resilient sealing device adapted to close the exposed opening in a telephone subscriber jack to prevent entry of moisture, vermin and the like. The device includes a cap-like body having a continuous peripheral edge which contacts a planar surface surrounding the plug opening, and a smaller opening at an opposite end thereof which resiliently clamps a flattened cable leading to subscriber equipment, such as a telephone handset at one end and a corresponding plug engaging jack at an opposite end. The opening is shiftable along the cable to increase the resilient force applied to the peripheral edge. The edge is also reinforced along one rectilinear side to prevent distortion by contact with the release lever of the plug, and accomodate for commerical manufacturing tolerances encountered in jacks of different manufacture.
