Paper Abstract

With the maturing of the G.723.1 and G.729 voice encoding algorithms, low-cost good-performance compressed voice becomes more readily available. At the same time, the ITU has just completed the AAL 2 (ATM adaptation layer) specification based on the 'mini-packet' technology which fits naturally with the transfer of packetized compressed voice over ATM. As a result, there is a great deal of interest in the marketplace to develop specification(s) based on AAL 2. This paper describes the current status of the AAL 2 standards in the ITU (International Telephone Union) and the activities in the ATM Forum on the use of AAL 2 in the landline trunking application.
