PPPoA (PPP over ATM)

An encapsulation typically used by DSL service providers on an ATM based network. Compared with PPPoE. it can reduce overhead slightly (around 0.58%). PPoA avoids some PPPoE issues due to having a MTU lower than that of standard Ethernet transmission protocols. It also supports the VC-MUX and LLC based encapsulation types.
