摘要: A modularized main distributing frame system (100) for interconnecting outside plant cables (140-143) with central office equipment leads (230,231) includes an overhead racking arrangement to route tie cables (130,131) and the equipment leads to framework line-ups (110,120). The tie cables connect the outside plant cables to widely dispersed appearances of frame terminals. To avoid crosses of tie cables as well as minimizing cable lengths and routes, the tie cables are routed using a methodology which partitions the cables in groupings. Each grouping is allocated a separate in-line spreading rack (160-163) to distribute the tie cables. In multiple line-up systems, another level of overhead racks (150,170,171) distributes the tie cables to the horizontally displaced spreading racks. Equipment leads are routed on a complementary racking structure (190-195) utilizing a methodology similar to the tie cabling technique.

摘要: An electrical protector device (10) for grounding excessive voltage and excessive current to safeguard telecommunications circuits includes a heat coil assembly (100) for sensing and directing excessive current to ground, and a spark gap arrester (200), axially aligned with the heat coil assembly (100), for sensing and controlling excessive voltage. Whenever an overcurrent condition is encountered, heat coil mechanism (110) is displaced to provide metallic contact of the incoming line to a ground structure (300). In addition, the device is adapted to provide protected testing of both incoming pairs and office equipment. Two test points (123) formed as part of the heat coil assembly (100) are in contact with the individual wires of the incoming line. These two test points are accessible through apertures (402) in the protector housing (400).

摘要: Portable test apparatus utilized to access a field of test points comprises either a single access tool (100) or a multiple access adaptor (200) depending on the mode of testing required. Tool (100) is usually employed for accessing the field to effect aperiodic testing whereas adaptor (200) is generally used for planned test activities.Tool (100) comprises body (111), guide assembly (150) and cover plater (170) which house clamp assembly (130) and pin contact assembly (180). Clamp assembly (130) operates in scissor-like fashion for engaging and disengaging tool (100) from test field grips (401). Spring-loaded pins (181) penetrate apertures (403) within the test field to contact the test points.Adaptor (200) comprises body (211), center panel (240) and guide (260) which enclose pin contact assembly (280); in addition, cam-lever drive assembly (210) attached to body (211). Drive assembly (210) has means for grasping a frame (50) associated with the test field so as to draw body (211) towards frame (50). In the engaged position, spring-loaded pins (281) contact the test point. Recesses (266) in the front face of guide (260) align juxtaposed test field grips to establish a uniform field of test points.Multiple slots in the drive assembly provide flexibility for test connector applications such as testing on the panel, outside plant or equipment and on protector families of different heights; however, all units in the panel must be the same height.

摘要: An electrical terminating arrangement (100) serving as an interconnection juncture for joining central office equipment with outside plant facilities, an access point for testing and a protection provisioning point comprises connector apparatus (402), tie cabling (500) and protector apparatus (110) wherein the conventional stand-alone test field appearance is eliminated. Test access is provided directly through sockets (130) in front face (113) of protector apparatus (110), or indirectly to test lands through apertures (403) in protector device (400) inserted in sockets (130). Reliability is achieved by utilizing connector (170) to couple protector apparatus (110) to a mated connector on the outside plant stub cable. Installation complexity is reduced by employing snap-in details (190) as well as plug-in details.
