Object
Controls and reflects the status of rows in this table.
There is no restriction on the changing of values in this
table while their associated rows are active, with the
exception of:
1. If a modulation profile is being referenced by one
or more upstream channels, an attempt to set the value
of docsIfCmtsModChannelType returns an
'inconsistentValue' error.
2. If a modulation profile is being referenced by one
or more upstream channels, an attempt to set
docsIfCmtsModControl to destroy(6) or notInService(2)
returns an 'inconsistentValue' error.
