ATM AAL2 protocol efficiency for supporting Voice over DSL

The 8th International Conference on Advances in Communications and Control - COMCON’8, Rethymnon, Greece, June 2001.

Abstract: Voice-over-DSL (VoDSL) technology provides a major boost to competition in local telephony market by greatly reducing the cost of local access. VoDSL leverages the high-speed transmission of DSL technology to deliver multiple telephony circuits plus high-speed data over a single loop. Although the data services delivered over xDSL are usually IP-based, native ATM is the ideal technology choice for offering data and voice services, since it enables multiple priority levels to be specified, allowing the highest priority to voice traffic. The AAL2 protocol has been recently standardized for bandwidth efficient transmission of delay sensitive, low bit-rate voice services. In this paper, we present comparative results using simulations techniques of the efficiency and performance of AAL2, AAL1 and IP/AAL5 to support voice in a DSL environment.
