Abstract

The invention provides a spectrum management method and device and a computer readable storage medium. The frequency spectrum method comprises the following steps: acquiring the maximum rate of a port of each first transmission mode; according to the maximum rate of the port of each first transmission mode, determining a subcarrier cut-off frequency point occupied by link establishment of the client terminal equipment of each first transmission mode; and taking the maximum subcarrier cut-off frequency point in the subcarrier cut-off frequency points occupied by the link establishment of the client terminal devices in the first transmission mode as the subcarrier start frequency point occupied by the link establishment of the second transmission mode. In the embodiment of the invention, the maximum subcarrier cut-off frequency point in the first transmission mode is used as the subcarrier start frequency point in the second transmission mode, so that the frequency band range of the second transmission mode is dynamically adjusted; a local side device supporting a new transmission mode can be compatible with a client terminal device in an old transmission mode so as to reduce crosstalk and unstable port link establishment.

Description

technical field [0001] Embodiments of the present disclosure relate to but are not limited to the field of communication technologies, and in particular, relate to a spectrum management method, device, and computer-readable storage medium. Background technique [0002] In Digital Subscriber Line Access Multiplexer (Digital Subscriber Line Access Multiplexer, DSLAM) system, Digital Subscriber Line (Digital Subscriber Line, DSL) technology has experienced Asymmetric Digital Subscriber Line (Asymmetric Digital Subscriber Line, ADSL), ultra-high speed digital subscriber Line (Very High Speed ​​Digital Subscriber Line, VDSL), G.Vector, G.fast, etc., to meet the increasingly higher bandwidth requirements. ADSL, VDSL, G.Vector, and G.FAST are called transmission modes in DSL equipment. With the deployment of DSL new technology equipment, there are central office equipment supporting the new transmission mode that cannot be compatible with the client terminal equipment of the old t...
