MTP3 Timestamp

This value is a 1msec resolution, modulus 2^32 timestamp derived from the internal processing logic of MTP3. The datum of this timestamp is established internally by each MTP3 at the time the signalling stack is configured and cannot be set.

As presented, the timestamp should only be used for relative timing of MTP3 Q.752 events and reports within a signaling stack. The timestamp for interval reports identify the time associated with the end of the reporting interval and not the time of the actual report. Consequently, host attempts to correlate the timestamp to a time datum must consider only the 1st interval report of a sequence for this correlation.

Interval sequence number

This value is a modulus 2^32 sequence number which identifies the reporting interval. The initial value for the first reporting interval following start or restart of interval reporting is 1.
