PPPoA

Short for Point-to-Point Protocol over Asynchronous Transfer Mode (ATM).  PPPoA relies on two widely accepted standards: PPP and ATM. It is an  end-to-end asymmetric digital subscriber line (ADSL) architecture. IP packets travel from the PC over Ethernet to the DSL modem, called the ADSL transceiver unit-remote (ATU-R). The ATU-R adds the PPP protocol to the IP packets and transports them to the carrier's Digital Subscriber Line Access Multiple (DSLAM) via ATM. It is a technology becoming more popular with DSL providers.
