The state of TDM indicators when the TDM PW last declared
an error second (either as ES, SES or a second with
errors inside a UAS) condition. At this time, only LOPS
can create a failure. Since indicators other than LOPS are
useful, all are latched here. For bit definitions, see
cpwCTDMCurrentIndications above.
Note: the algorithm used to latch these indications when
entering a defect state is implementation specific.
