    In order to remain viable the common carriers to develop "optical access network" based on FTTH as soon as possible. Many problems must be overcome in moving from the "metallic" world to the "optical" world, but if carriers hesitate and fail to make this move then they will be in a hopeless situation in the 21st century. This article discusses concepts for realizing optical access networks that ar... View full abstract»

    The European Economic Community's (EC) RACE program (Research and Development in Advanced Communications Technologies in Europe) started with a definition phase in 1986. The main effort of the first phase was aimed at customer access connections (CACs) and customer premises networks (CPNs), as well as identification of services that will use these high-speed networks. In the second phase, which be... View full abstract»

    Fiber-in-the-loop (FITL) systems enable the distribution transport of existing telecommunications services and future broadband services over fiber optic media. An FITL system comprises a host digital terminal (HDT) connected to some number of optical network units (ONUs) via a fiber optic passive distribution network (PDN). Each ONU provides metallic service interfaces via short drops consisting ... View full abstract»

    The data link layer protocol for the integrated services digital network (ISDN) user/network interface, known as link access protocol-D (LAPD), is a protocol that operates at layer 2 of the open systems interconnection (OSI) architecture. Its purpose is to safely convey information between layer 3 entities using the D-channel. The information types that LAPD is intended to transport include call c... View full abstract»

    The vision of an all-fiber telecommunications network delivering an ever increasing variety of services to both business and residential customers has been the subject of much speculation for more than a decade. However, although optical fibers are now used routinely for longer haul transmission and for connections to large business customers; fiber to provide the final link to the generality of c...
