ABSTRACT:
A device is capable of electronically reversing the polarity of a polarized data link interface used between a data termination equipment (DTE) and either a data communication equipment (DCE) or another data termination equipment (DTE). In this manner, the establishment of physical level connectivity in the data link interface is simplified and the interfacing of DTEs (such as computers) and peripheral devices is improved.
