Abstract

The invention discloses MODEM, DSLAM (Digital Subscriber Line Access Multiplexer), ADSL (Asymmetrical Digital Subscriber Loop) equipment and a communication method thereof, wherein the method comprises the following steps of: conducting reverse power supply to a port corresponding to a user side MODEM in the local side DSLAM of the ADSL equipment through a power supply signal after the user side MODEM of the ADSL equipment is electrified; and stopping power supply to the port corresponding to a user side MODEM in the local side DSLAM of the ADSL equipment after the user side MODEM is diselectrified. According to the invention, the energy consumption of the DSLAM can be effectively reduced, and the service life of the equipment can be prolonged.

Description

technical field [0001] The present invention relates to the technical field of energy saving, in particular, to a modem (Modulator and Demodulator, MODEM), a digital subscriber line access multiplexer (Digital Subscriber Line Access Multiplexer, DSLAM), an asymmetric digital subscriber line (Asymmetric Digital Subscriber Line, ADSL ) equipment and its communication method. Background technique [0002] ADSL / ADSL2+ is the main fixed broadband access method in my country. At present, the central office equipment (for example, DSLAM) and user equipment (for example, MODEM) of the ADSL system have their own power supplies, and the user port of the DSLAM is always in live work after activation. state. [0003] figure 1 It is a schematic diagram of the workflow of the existing ADSL system. [0004] Such as figure 1 shown, including: [0005] S102, a network management enabling port in the local DSLAM; [0006] S104, the user port in the central office DSLAM is in a working st...
