(Point-to-Point Protocol Over ATM) Using the PPP dial-up protocol with ATM as the transport. Used by some DSL providers, IP packets travel from the PC over Ethernet to the DSL modem, officially known as an "ADSL transceiver unit-remote" (ATU-R). The ATU-R adds the PPP protocol to the IP packets and transports them to the carrier's DSLAM via ATM.|
PPPoEoA (PPP Over Ethernet Over ATM)
PPPoEoA is an alternative to PPPoA. PPPoEoA takes advantage of the authentication and security features of PPP by providing end-to-end PPP connectivity. It establishes the PPP session in the PC rather than at the DSL modem. See PPP, PPPoE, DSL and ATM.
