The two terminating devices receive transmitted data packets according to an expected arrival format for data packets. The segment is monitored over a monitoring time interval for continuity of the expected arrival format. An unavailable time after a change in arrival format of data packets from the expected arrival formal to a change in arrival format of data packets back to the expected arrival format is detected.
