CPF101IG Introduction:
CPF101IG splitter card that been specifically designed implement functionality pass filter ISDN-BA with 2B1Q 4B3T baseband linecodes over ADSL application. CPF101IG integrates pass filters that block high frequency energy from reaching ISDN-BA device provide isolation from impedance effects ISDN-BA device ADSL. Because ISDN splitter connects directly subscriber loop media, must also provide some protection externally induced line hits faults which could damage attached equipment endanger humans interacting with installed equipment. circuit protection will provided mostly standard central office line protection means additional protection measures built into splitter protect against line overstress which could damage splitter itself. electrical transmission specification based both ETSI 952-1-3 V1.1.1 ETSI V1.2.1 ISDN-BA requirements POTS requirements, respectively.
