Point-to-Point Protocol over ATM
PPPoA

   <networking> (PPPoA) A network {protocol} for encapsulating
   {PPP} {frames} in {ATM} {AAL5}.  It is used mainly with {cable
   modem}, {DSL} and {ADSL} services.

   PPPoA offers standard PPP features such as {authentication},
   {encryption}, and {compression}.  It is very slightly more
   efficient than {PPPoE} and, like PPPoE, supports {VC-MUX} and
   {LLC} encapsulation.

   PPPoA is specified in {RFC 2364}.
