Kenny,
I am not so sure. You must be talking about RFC 1149 instead. I don't
believe token ring is mention in RFC 2549. Token Ring is not stated in RFC
1149 but it does talk about Point to Point connection. That would be the
case if you are not using a MAU in a Token Ring network.

Haven't you heard of the new high speed 'token ring ethernet adaptor' as
defined in RFC 2549???? ;)
