ABSTRACT:
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.
