["Mark S. Lewis" <[e-mail]>]

Thanks for the comments.  Sounds like we drop:

   mdmStatWatchdogTimeouts
   mdmStatInactivityTimeouts

These are in question:

    mdmStatsDTERingNoAnswers
    mdmStatsMdmRingNoAnswers (not in recent versions of draft)

I suggest without strong justification and consensus that we need
these, they should be deferred until the extensions mib.  (People that
want these should make their case.)

Lastly, I like Rick's suggestion about the keeping the stats by link
rate.  We need to add description to them that explains they are
counted at their initial rate not some subsequently negotiated rate.

There will be an entire instance of the modem mib for each modem.
This has not been reflected in the draft yet, but this is the plan.
Everything in the current draft will be pushed down one level into a
table indexed by modem.  These changes need to be made to the draft.

... Mark
