Method, device and system for line management
Abstract:
A method for line management includes: acquiring running parameters of a subscriber line; computing a transmitting power spectral density, PSD, and reference virtual noise of the subscriber line according to the running parameters; activating the subscriber line according to the transmitting PSD and the reference virtual noise. A device and system for line management are provided correspondingly. Reference virtual noise needed by virtual noise technology is set rationally according to the information provided by dynamic spectrum management, DSM, Level 2 algorithm. The utilization of the virtual noise technology improves the line stability under the DSM Level 2 algorithm, and has an effect of optimizing the subscriber line.
