used to create or delete an entry in the
descriptor table.
Creation of the row requires a row index (see
frAtmIwfConnectionDescriptorIndexNext). If not

of the row will be created and initialized to the
default value. During creation, this object MAY
be set to 'createAndGo(4)' or 'createAndWait(5)'.
The object MUST contain the value 'active(1)'
