+    STATUS          current
+    DESCRIPTION
+        "The value of the optical parameter that is being monitored.
+
+        The range of values varies depending on the type of optical
+        parameter being monitored, as identified by a corresponding
+        object with syntax OpticalParameterType.
+
+        When the optical parameter being monitored is 'power' or
+        'acPower', the supported range is from -400 to 250, in
+        1/10ths of dBm.
+        Example: A value of -300 represents a power level of -30.0 dBm.
+
+        When the optical parameter being monitored is 'laserTemp' or
+        'ambientTemp', the supported range is from -500 to 850, in
+        1/10ths of degrees centigrade.
+        Example: A value of 235 represents a temperature reading of
+        23.5 degrees C.
+
+        When the optical parameter being monitored is 'biasCurrent',
+        the supported range is from 0 to 10000, in 100s of
+        microamperes.
+        Example: A value of 500 represents a bias current reading of
+        50,000 microamperes.
+
+        When the optical parameter being monitored is 'peltierCurrent',
+        the supported range is from -10000 to 10000, in milliamperes.
+
+        When the optical parameter being monitored is 'xcvrVoltage',
+        the supported range is from 0 to 10000, in millivolts.
+
+        The distinguished value of '-1000000' indicates that the object
+        has not yet been initialized or does not apply.

+        To minimize the probability of prematurely reacting to

+        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).

+OpticalAlarmSeverity ::= TEXTUAL-CONVENTION
+    STATUS          current
+    DESCRIPTION
+        "The severity of a trouble condition. A smaller enumerated
+        integer value indicates that the condition is more severe.
+
+        The severities are defined as follows:
+
+        'critical'    An alarm used to indicate a severe,
+                      service-affecting condition has occurred and that
+                      immediate corrective action is imperative,
+                      regardless of the time of day or day of the week.
+
+        'major'       An alarm used for hardware or software conditions
+                      that indicate a serious disruption of service or
+                      malfunctioning or failure of important hardware.
+                      These troubles require the immediate attention and
+                      response of a technician to restore or maintain
+                      system capability. The urgency is less than in
+                      critical situations because of a lesser immediate
+                      or impending effect on service or system
+                      performance.
+
+        'minor'       An alarm used for troubles that do not have a
+                      serious effect on service to customers or for
+                      troubles in hardware that are not essential to
+                      the operation of the system.
+
+        'notAlarmed'  An event used for troubles that do not require
+                      action, for troubles that are reported as a
+                      result of manually initiated diagnostics, or for
+                      transient events such as crossing warning
+                      thresholds.  This event can also be used to
+                      raise attention to a condition that could
+                      possibly be an impending problem.
+
+        'notReported' An event used for troubles similar to those
+                      described under 'notAlarmed', and that
+                      do not cause notifications to be generated. The
+                      information for these events is retrievable from
+                      the network element.
+
+        'cleared'     This value indicates that a previously
+                      occuring alarm condition has been cleared, or
+                      that no trouble condition is present.
