Subject: HPR over Frame-Relay

In section A.2.2 of the draft HPR specification I note the proposal to use
level 2 protocol identifier X'7081' to indicate the absence of any level 2
protocol.  I have two problems with this:

 1) it violates the Q.933 specification.  The first octet of a multi-octet
    level 2 protocol identifier for a user specified protocol must be X'50'
    according to Q.933.  For a standard protocol it must be X'4x'.  As it
    stands this page should indicate that bytes 4-5 should contain X'5081'.

 2) it seems perverse to identify the ABSENCE of a level 2 protocol as a
    USER defined protocol.  It would seem more reasonable to request the
    frame-relay forum to define the absence of a level 2 protocol as one of
    the standard options.
