OPTIMIZING THE TRANSMIT POWER SPECTRUM DENSITY (PSD) OF A REMOTELY DEPLOYED LINE TO ENSURE SPECTRAL COMPATIBILITY |
摘要 |
<p>An apparatus comprising a transmitter at a digital subscriber line (DSL) Cabinet configured to transmit a downstream signal in a subscriber line according to a power spectral density (PSD) configuration, wherein the PSD configuration comprises a cutoff frequency based on a required data-rate of the subscriber line. Also included is an apparatus comprising at least one processor configured to implement a method comprising determining a downstream PSD for a PSD mask for a DSL, determining a cutoff frequency for the PSD profile based on a data-rate required for the DSL, and adjusting a downstream signal power on the DSL according to the PSD mask. Included is a method comprising configuring a plurality of transmitted PSDs for a plurality of Exchange deployed lines and Cabinet deployed lines by varying a plurality of cutoff frequencies corresponding to the transmitted PSDs, wherein the cutoff frequencies are varied by line, with time, or both.</p> |
