Object
column
r/w
Unsigned32
This attribute is used by the CMTS to be inserted in the PLC Trigger
Message Block to identify a CM or a group of CMs expected to perform
Symbol Capture measurements for the designated symbol.
This value can only be changed while a test is not in progress. An attempt
to set this value while the value of 'docsPnmCmtsDsOfdmSymMeasStatus' is
'busy' will return 'inconsistentValue'.
