OpticalAlarmStatus
A bitmap that indicates the current status of thresholds on an interface. The bit is set to 1 if the threshold is currently being exceeded on the interface and will be set to 0 otherwise. (MSB) (LSB) 7 6 5 4 3 2 1 0 +----------------------+ | | +----------------------+ | | | | | | | +-- High alarm threshold | | +----- High warning threshold | +-------- Low alarm threshold +----------- Low warning threshold To minimize the probability of prematurely reacting to momentary signal variations, a soak time may be incorporated into the status indications in the following manner. The indication is set when the threshold violation persists for a period of time that exceeds the set soak interval. The indication is cleared when no threshold violation occurs for a period of time which exceeds the clear soak interval. In GR-2918-CORE, the recommended set soak interval is 2.5 seconds (plus/minus 0.5 seconds), and the recommended clear soak interval is 10 seconds (plus/minus 0.5 seconds).
