Method and apparatus for transmitting signals over wire connections

摘要: A method and apparatus to transmit data over different channels from a transmitter 16, such as DSLAM, one or more receivers 51-53, each of which is connected via respective wire connection 21-23. For channel steps (i) (iii) are iteratively performed until criteria satisfied transmission power determined for that channel. Step comprises, determining values function depending on attributes selected from: number tones, frequency spacing adjacent maximum gain the (ii) using value step determine power. comprises whether not powers satisfy criteria; thereafter transmitting at current powers. The tones referred may be discrete multi-tones (DMT) used in Digital Subscriber Line Systems (DSL).
