COURSE # TOO-370
UNDERSTANDING ATM TECHNOLOGY AND DESIGN
ATM technology at a glance – from the concepts to the most current
applications.
Asynchronous transfer mode (ATM) is a high-bandwidth, low-delay switching and multiplexing technology now available to corporate planners. It is being deployed in support of networks that carry an organization's traditional data and LAN traffic, video flows, image information, and even voice. In addition, nearly all major carriers in the United States (interexchange carriers, competitive local exchange carriers, and incumbent local exchange carriers) are now deploying or
plan to deploy some form of ATM-based backbone.
This course provides the essential information needed for understanding of this technology.
Applications and benefits:
You will benefit by enhancing your understanding of the:
- Wideband communications requirements.
- ATM technology: current and future.
- Fundamental elements of ATM networks.
- ATM systems and networks
Who should attend:
This course provides essential information needed to assist corporate and carrier planners in making ATM a reality for their organizations. Users, equipment suppliers, and carriers who need to understand ATM switching technology, economics, design considerations, and available carrier service in order to effectively deploy ATM and its capabilities. This course has no prerequisites; however, prior training in telecommunications of equivalent experience will be helpful.
