This controls inversion of the transmit BERT pattern. Possible values are : notInverted(1): Pattern is transmitted normally. inverted(2): Each Mark is replaced by Space and vice versa. For predefined BERT patterns, the value for this Object may not be modified. An implementation may choose to ignore the value of this object, for BERT patterns other than 'userPattern'. When the value is ignored, the object contains the value chosen by the underlying hardware. This object can not be modified when the BERT is running i.e cbRowStatus is active(1).
