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.
