FREQUENCY AGILE TRANSPONDER

摘要

One or more pieces of equipment of a hybrid fiber-coaxial (HFC) network (2) has a frequency agile transponder (34) connected thereto. Each frequency agile transponder (34) includes a transmitter (T) and a receiver (R) which are connectable to a coaxial line of the HFC network (2). Bidirectional communications can occur between a controller (12) and each frequency agile transponder (34) via the HFC network (2). The frequency agile transponder (34) has analog inputs/outputs connectable to test points of the one or more pieces of equipment (14, 20, 24) of the HFC network (2). The frequency agile transponder (34) can test the test points and supply to the controller (12) the results of the test. The transmit and receive center frequencies of the transmitter (T) and receiver (R) of the frequency agile transponder (34) can be selectively and remotely adjusted by the controller (12) to avoid signals at carrier frequencies utilized to transmit program material, data signals and/or telephony signals.
