Understanding ATM
2-Day Session

Understanding ATM will show you why communications professionals are increasingly viewing Asynchronous Transfer Mode as the high bandwidth "final solution." The issues will be presented in a non-biased manner. The concepts, technologies and standards concerns will be detailed. Learn what the migration paths are to this capability and how the services that are readily available can help you gradually access the higher speed networking capabilities.
