Abstract

To satisfy the market need for voice over ATM (VoATM), ATM Adaptation Layer Type 2 (AAL2) has been defined in the ITU-T Recommendation I.363.2. AAL2 is designed with the capabilities to support multiple voice users per ATM connection and to transport compressed/silence-suppressed variable-bit-rate (VBR) voice traffic. Recently, there is a growing interest in the impact of AAL2 trunking/switching on the digital telephone switching systems. This paper analyzes the performance and the feasibility of AAL2 trunking/switching for VBR voice transport when the traditional digital telephone switching system is replaced by the AAL2 trunking/switching system.
