The current exclusive RIG vendor, Qualitrol, is phasing out support for the RIG devices. ISO-NE has undertaken a project to replace the RIG infrastructure with a DNP3-based Communication Front End (CFE) and Remote Terminal Unit (RTU) system. DNP3 was chosen as a protocol because of its non-proprietary nature and wide availability of solutions from multiple vendors.
