ATM over ADSL probe in Telecom Italia environment

This paper covers access network performance analysis by deploying asynchronous transfer mode (ATM) over ADSL within the Telecom Italia experimental department "EXANET" (experimental ATM network). In this scenario, data traffic leaves customer site as ATM traffic running over ADSL modem links, it is aggregated via digital subscriber line access multiplexer (DSLAM) at the central office (CO) and then dropped onto the high-speed ATM switching fabric. The Italian telephone company was eager to use ADSL as a way to relieve congestion on their circuit-switched voice telephony system, increasingly bogged down by the growth of the Internet and by long data transmissions.
