Physical-layer test of coaxial access device in protocol mode

HINOC (High Performance Network over Coax) is a coaxial cable access technology used in tri-networks integration. To test and measure the physical-layer performance of HINOC modem (HM), a protocol-mode approach including a specific HINOC MAC layer and test script scheduler of HB is designed to change the status and parameters of the HM during the test. Power, spectrum, modulation and demodulation quality can be test with data flow on communication link. This method can test HM´s performance of transmitter and receiver without any modification to the HM, which has more advantages than the traditional non-protocol physical-layer test approach.
