AAL type 2 is expected to become a key technology for providing various services, mainly compressed voice, over widespread ATM networks. This paper clarifies VC (virtual channel) characteristics, i.e. ATM VC bearer (DBR and SBR) and traffic parameters (PCR and SCR), for multiplexing AAL type 2 connections, with changing in the number of AAL type 2 connections in a VC to apply AAL type 2 to actual services in ATM networks. The traffic parameters were numerically evaluated by computer simulation and the VC multiplexing effect was also evaluated using a simple connection admission control algorithm. We show the applicable domain where SBR VCs can be used instead of introducing AAL type 2 switches and re-multiplexing these VCs into larger DBR VCs. The results of this paper can be used to design a VC structure for AAL type 2 traffic in ATM networks.
