PPPoA stands for Point to Point Protocol over ATM Adaptation Layer 5 (AAL5). A PPPoA
connection functions like a dial-up Internet connection. The router encapsulates the PPP
session based on RFC1483 and sends it through an ATM PVC (Permanent Virtual Circuit)
to the Internet Service Provider’s (ISP) DSLAM (digital access multiplexer). Please refer
to RFC2364 for more information on PPPoA.
