DescriptionField
Indicates whether the tunable dispersion compensator
(TDC) is in the acquiring state or locked state. The
status is invalid if there is a major alarm.
Status
Indicates a value between –700 and +700 packets per
second (pps). The dispersion setting is read from the
optics module after the tunable dispersion
compensator (TDC) has locked.
