ZyXEL – SBG Support Notes
PPPoA is 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.
Does the SBG Series support PPPoA?
Yes. All SBG Series supports PPPoA.

Why does my provider use PPPoE/PPPoA?

existing applications and services including authentication, accounting,
