Telecommunications cabling arrangement

This invention relates to an improved modular communication cabling system for use in buildings and office areas, such as within office furniture components having raceways therethrough, to route a plurality of communications circuits or links to working areas wherein selected circuits can be accessed. A communication cabling system wherein elongate communication distribution assemblies (CDAs) are joined serially together by connector units at opposite ends thereof. The interconnected CDAs include access ports or openings into which a tap unit may be inserted and connected to a circuit which is accessible through the access port. Each CDA can be adapted to carry a selected number of circuits wherein each connector unit at an opposite end of a CDA includes a block-like shielded housing having a predetermined number of mounting sockets on a back end thereof. A plurality of modular cable assemblies are provided which have plugs that plug into a respective one of the mounting sockets of the shielded housing so as to assemble a CDA. This system provides for the ready construction, installation and reconfiguration of the communication cabling system.
