Reports the state of the Optical Switch. Not all enumerations must be supported. For example, an A-B optical switch may support only the pathA and pathB enumerations while a cross-bar switch may support cross, bar, bothA or bothB or only cross and bar but not pathA and pathB enumerations. A value pathA(1) indicates that the switch output is being fed by side A (first input) of the switch. This enumeration is intended for use by an A-B switch. A value pathB(2) indicates that the switch output is being fed by side B (second input) of the switch. This enumeration is intended for use by an A-B switch. A value cross(3) indicates that the switch outputs are fed as follows: Side A (first or primary) output is connected to side B (second or alternate) input. Side B (second or alternate) output is connected to side A (first or primary) input. This enumeration is intended for use by a cross-bar switch. A value bar(4) indicates that the switch outputs are fed as follows: Side A (first or primary) output is connected to side A (first or primary) input. Side B (second or alternate) output is connected to side B (second or alternate) input. This enumeration is intended for use by a cross-bar switch. A value bothA(5) indicates that the switch outputs are fed as follows: Side A (first or primary) output is connected to side A (first or primary) input. Side B (second or alternate) output is connected to side A (first or primary) input. This enumeration is intended for use by a cross-bar switch. A value bothB(6) indicates that the switch outputs are fed as follows: Side A (first or primary) output is connected to side B (second or alternate) input. Side B (second or alternate) output is connected to side B (second or alternate) input. This enumeration is intended for use by a cross-bar switch.
