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.
PPPoA Baseline Architecture This document describes an end-to-end asymmetric digital subscriber line (ADSL) architecture using Point-to-Point Protocol over Asynchronous Transfer Mode (PPPoA). Although most deployments are based on the bridging architecture, PPPoA is gaining tremendous popularity and will form a larger portion of future ADSL deployments.
