I have to answer the following question from an RFP: FDDI Devices must use the latest revision of SMT per ANSI X3T9.5 standards and must support graceful ring insertion. Is this "graceful ring insertion" a new function of SMT, or is this the old multi-MAC concentrator issue again?

    It's not X3T9.5 anymore, but our products do support the latest SMT
    standard which I believe is at revision 7.3.

    I recall reading somewhere why we don't support this, but that it's not
    all it's cracked up to be either.  I don't have any specific pointers,
    but do a search in this Notes conference for "graceful" or just look
    for entries posted by Paul Koning.  I'm sure he wrote a reply on this
    subject at some point.

|     Graceful insertion is NOT a requirement of SMT. It is a vendor specific
    implementation detail. This idea has been around for a while, so I 
    won't rehash it here. 
    
    SMT is now an approved document, so the correct reference is 
    X3.229-1994. This corresponds to SMT 7.3
