The present patent application relates to a method and a modem for providingfor reliable and low cost data communication in cable television networks, such as Master Antenna Television networks and Satellite Master Antenna Television networks. This is achieved through host and node modems using power line transceivers (2) for handling data communication and providing modulation/ demodulation. Separate amplifying (3, 11) and filtering (4, 5, 9,10) means are provided in the receive (RX) and transmit (TX) signal paths of the power line transceivers (2). The impedance of the receive (RX) and transmit (TX) signals paths is matched, and the signal paths combined (13) into one. |
