A significant issue facing telecommunications carriers is the role of switching in future networks. A key question in using switches is performance, which is measured by the speed of network trunks that carry user information, the round trip delay of a network and the rate of information loss. Although data networks led by the Internet are expected to boost broadband demand, the load is not yet enough to justify the economics of an immediate jump to OC-48., Vendors who assert that the network will be driven to the OC-48 level anytime soon are ignoring the lesson of ATM. Like many terms that have achieved popular recognition, 'switching' [...]

Local and long distance carriers can provide asynchronous transfer mode (ATM) services and gain profit from the enterprise. Most telecommunications providers have cancelled their plans to offer ATM services because of very low revenue expectations. However, ATM services can be profitable if carriers include higher-layer services. These include providing local area network features at the media-access control or logical link control level, and offering network-layer protocols., Most local and long distance carriers have planned asynchronous transfer mode (ATM) services since the early 1990s. Many already have delivered some offerings to subscribers, and it is fair to [...]

Two trends are being analyzed as to their respective uses for the central office of the future. One factor is the evolution of voice telephony, which stands to be reshaped by the Advanced Intelligent Network (AIN), a new formulation of network element relationships that can enhance basic phone services. The other factor is the growth of non-voice demand traffic as reflected in the design of asynchronous transfer mode (ATM). Although AIN may dominate total public carrier traffic, ATM can serve as an overlay network technology to manage bandwidth in special network contexts., Everyone, particularly planners, is interested in the future. But the problem with 'the future' is that there seems to be more than one force shaping it. Planners would have an [...]

Telecommunications carriers can still gain market acceptance of asynchronous transfer mode (ATM) technology provided they respond to customers' demands. According to CIMI Corp.'s 1995 poll of 118 data communication service users, they will deploy ATM if it is priced 23% lower than existing services and if ATM links and customer premises equipment are flexible for subsequent migration to new applications., Have public carriers already thrown Asynchronous Transfer Mode (ATM) to the wolves? Here's a detailed action plan to make ATM pay off in the core of the public network. In [...]
