    The emerging customer-oriented definition of switched service availability, including how this definition is useful for a customer comparing a switched service with a dedicated service, is discussed. The ways in which a user of a switched service can evaluate the service's availability without having access to network internal information are described. They ways in which network providers can man... View full abstract»

    The actions taken by end-users, service providers, standards bodies, and government and regulators agencies relating to network reliability and service outages are reviewed. End-to-end customer perceivable characteristics of network reliability and network outages are identified. The traditional definition of reliability is extended to include reliability of a telecommunication network and service... View full abstract»

    The current state of reliability specification and design methods is described. These methods aim to keep the expected value of the effect of network failures on the users under a certain level by assuming that the effect is approximately proportional to the outage time. The evaluation of long outages is discussed. Future reliability specification and design methods are also discussed.<> View full abstract»

    The reliability of local exchange carrier (LEC) networks is described using data obtained from diverse sources. These sources are Bellcore's Outage Performance Monitoring (OPM) process, which is designed to collect information on switch outages lasting two minutes or longer, the Automated Report Management Information System (ARMIS), which supplies reports to the US Federal Communications Commissi...

    The descriptions of the various congestion-control functions for the common channel signaling system No. 7 (SS7), which are spread widely and piecemeal across the CCITT recommendations, are presented. The protocol architecture of SS7, structured according to Open Systems Interconnection (OSI) principles, is described. The message transfer part (MTP) provides the OSI Layer 1 and 2 services, plus pa... View full abstract»

    A cost comparison for different broadband access network configurations in the context of fiber-in-the-loop (FITL) is presented. The basic architecture and features of the asynchronous transfer mode (ATM) passive optical network (APON) are described. The design objectives of each of the APON building blocks are clarified, and their relation to the system philosophy is indicated. The building block... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1951 KB)

    The major impairments in lightwave systems and the signal-processing techniques that can be used to reduce these impairments are discussed. Guidelines for the use of these techniques are presented. These guidelines are used to determine the techniques with the most potential for providing improved performance in long-haul systems, local-area networks, and local loop systems. Although many of the t... View full abstract»
