A read-write Unsigned32 setting the number of Consecutively Severely Errored Seconds allowed within a one-hour window before the p2mpSuConsecSevErrSecAlarmTrap is generated. Because CSES specifically flags burst-type severe errors, this hourly threshold gives an early automatic alert focused on sustained outage-like conditions rather than scattered single-second glitches. For example, an admin monitoring a link prone to brief total signal blackouts would rely on p2mpSuLink1HrCSESAlarmThresh to catch repeated consecutive-error bursts even if the overall error-second count for the hour looks otherwise unremarkable.
