Broadband is the provision of subscriber access targeting business and residential customers. It is regarded as an all purpose network that will provide integrated access and support a wide variety of applications in a flexible and cost-effective manner.
The transfer mode for broadband integrated services data networks (B-ISDN) must be able to handle both narrowband and broadband rates, continuous and spurts of traffic, satisfy delay or loss-sensitive quality requirements, and meet otherwise unforeseen demands. Neither circuit mode nor packet mode is suitable for meeting all of these requirements. Asynchronous transfer mode (ATM) exists between circuit and packet mode and is the target solution of B-ISDN. ATM is a specific packet-oriented transfer mode which uses an asynchronous time division multiplexing technique. It has been defined by the Consultative Committee for International Telegraphy and Telephone (CCITT) as a transfer mode in which information is organized into cells; it is asynchronous in the sense that the recurrence of cells containing information from an individual user is not necessarily periodic (Rendleman, 1998, p. 6).
The rise of ATM technology has resulted in increased information being available for transmission of more than just traditional textual data across LANs as well as through the Internet. In this way, companies with far-flung offices are able to use videoconferencing to hold meetings without having to have participants travel from one office to another. While timezones can be a problem when the locations are particularly dispersed, the logistics are far easier to manage when videoconferencing is used. The following chart illustrates the market penetration by a single provider, Sprint, with regard to broadband data networks. By the end of 1999, the company anticipates having 60 major metropolitan cities able to access high-bandwidth networks (Rendleman, 1998, p. 6).
