POWER CONTROL DATA DELIVERY CONSISTENCY IN COPPER PLANT |
摘要 |
A method and apparatus for transmit power control in a subscriber loop for high frequency data services are described. Transmit signal power levels are maintained at minimum levels for achieving acceptable communications between a transmitter and a receiver. Transmit signal power levels are adjusted dynamically on a link-by-link basis by employing command controllable transmit power attenuators at the transmitters. The transmit power attenuators are controlled by transmit signal power controllers which issue commands to the transmit power attenuators. Excess transmit power is avoided and parasitic signal coupling between communication links is reduced. The advantages are cross-talk reduction, longer loop length and higher data rates.
