Paul,

RFC2011 defines ipNetToMediaPhysAddres as a PhysAddress which is
imported from SNMPv2-TC. SNMPv2-TC defines this as:

 PhysAddress ::= TEXTUAL-CONVENTION
    DISPLAY-HINT "1x:"
    STATUS       current
    DESCRIPTION
            "Represents media- or physical-level addresses."
    SYNTAX       OCTET STRING

As you have said, just use IpoaAtmAddr.

E.164 encoded in native format means 15 octets in ASCII format as
oppose to a 8 octet BCD encoded one.

I don't think there is an issue with ipNetToMediaPhysAddress. I've
always thought that it was implementation dependent as to its actual
content. I will add a clarifying comment on this in the IPOA-MIB.
