Switched digital video access networks

Abstract

Telecommunications service providers are upgrading their network infrastructure to enhance telephony and to enable future video and data services. This discussion focuses on an access network that serves as a platform for transporting telephony and asynchronous transfer mode (ATM) data to the customer premises using fiber-in-the-loop (FITL) technology. The platform provides the building blocks that will enable service providers to furnish a wide variety of offerings, such as interactive and broadcast video, Internet access, and other high-bandwidth data communications. The platform is called the switched digital video (SDV) access network. This paper describes the SDV access network, and it also presents an example of how SDV network elements could be configured with other broadband network elements to provide an interactive video services network.
