Abstract: A passive fiber local access architecture and signaling plan is disclosed which enables the local exchange network to meet the need, as defined by the International Telecommunications Union(ITU) in References 7 and 8, for an economic means of providing a multitude of services to subscribers over a single medium. Integrating disparate signals compatibly and symmetrically over one medium dictates that all digital transmission and signaling at speeds in excess of 100 Mbps be used on the link. The additional bandwidth needed to support this expanded capacity demand points to glass fiber as the most suitable candidate for this role. A failure tolerant, diversely routed redundant ring cabling architecture provides a dedicated fiber or fiber pair to each premises from the local exchange carrier POP, eliminating the need for intermediate nodes. line power, signal splitters, amplifiers or metallic loops in the last mile. 12×12 cross connect units are deployed in the outside cable plant to meet user demand anywhere along the route, serving 500 or more homes from a single POP. The passive fiber subscriber line is activated and controlled by a set of out of band digital supervision signaling protocols that are compatible with Signaling System 7. These protocols replace existing DC loop closure supervision. Firmware is provided at both POP and subscriber ends of the link to administer and monitor link operations.
