Transceiver incorporates a new digital encoding technology. It is applicable in security and surveillance, access control systems, intelligent transportation systems (ITS) and SCADA. It incorporates plug-in personality circuit cards to easily configure a wide variety of data channels on this system. The functionality of the transceiver is further enhanced by their compatibility with PC based SpectraSmart network management and diagnostic software system. SpectraSmart supervises the operating parameters of the transmission system such as the status on digital carrier detects voltages, temperatures, optical levels etc.
