I think that this would be covered by the second of the two proposed
description clauses in my note (that's certainly what was intended):

      "This variable assumes the value true(1) if the data stored       XXX
      for this interval is both valid and complete.  It is set to       XXX
      false(2) if the data stored for this interval is incomplete       XXX
      or otherwise invalid because:                                     XXX
                                                                        XXX
      - the data stored for this interval is for a period greater       XXX
      or less than 15 minutes;  or                                      XXX
                                                                        XXX
      - some data is missing (e.g., when a near-end defect prevents     XXX
      some far-end data from being collected)."                         XXX

If you think that additional clarification is needed, however, you are
welcome to propose specific text.

It's certainly true that data cannot be collected when the interface is
off-line.  It had not occurred to me that someone might assume otherwise.
Again, if you feel that additional clarification is needed, please propose
specific text.
