In exisfing SECURBNET four level systems, the user must know, prior to SECURBNBT operation, if the system incurs a signal phase inversion. This must be known to allow proper data values to be decoded and placed into the range extension (REX) sync detectors. This invention removes the need to deter- mine if the systems inverts the inbound to outbound signal polarity while allowing proper RBX four level detection.
