Voice over ATM: an evaluation of implementation alternatives

The author identifies eight application scenarios for voice over ATM, and evaluates alternatives for implementing the required network functionality. For single voice calls this involves evaluation of adaptation type, QoS, echo canceller deployment, and use of partially filled cells. For a multiplex of at least three to six voice calls it involves evaluation of the structured data transport option in AAL1, interworking with DSn/En for fault management and QoS. These issues determine choices for network users plus implementation priorities for network operators.
