Embodiment 1

[0024] Such as figure 2 As shown, there is a power consumption control pin on the Line Driver, and a pin of the main controller is connected to the power consumption control pin. For example, the pin for power consumption control on the Line Driver can be the Power Down pin. The main controller can control the driving power of the Line Driver through high and low levels.

[0025] Combine below image 3 , introducing a method for reducing DSL power consumption provided by an embodiment of the present invention:

[0026] S301: the main controller controls the line driver to work alternately in a low power consumption state and a normal state through a pin connected to the Line Driver.

[0027] Among them, working in the low power consumption state and the normal state can be realized by reducing and restoring the driving power of the Line Driver. Reduce the power of the Line Driver, and the Line Driver will work in a low power consumption state, which can save energy consum...

Embodiment 2

[0040] A method for reducing DSL power consumption provided by another embodiment of the present invention:

[0041] S401: Make the line driver alternately work in a low power consumption state and a normal state.

[0042] S402: The DSP detects the remote activation request information from the remote end during a period of time when the Line Driver is working in a normal state. If the DSP detects the remote activation request information, execute step S403, otherwise execute step S401.

[0043] S403: the DSP controls the Line Driver to work in a normal state through the pin connected to the Line Driver.

[0044] Or after the DSP receives the remote activation request message, it sends another message to instruct the LineDriver to control itself to work in a normal state.

[0045] That is, the master controller in the first embodiment can be integrated in the DSP. Then the XDSL set starts to initialize.

[0046] S404: After the initialization is completed, the DSL line is ...

Embodiment 3

[0050] Such as Figure 4 As shown, the embodiment of the present invention also provides a device, which includes a line driver module and a digital signal processor module.

[0051] The line driver module works alternately in a low power consumption state and a normal state.

[0052] The digital signal processor module is used to detect the information sent by the line, and control the line driver module to change the working state according to the detected information.

[0053] The digital signal processor module includes a receiving module, a detection module and a control module. The receiving module receives the information sent by the line, and the detection module is connected to the receiving module to detect the information. If a remote activation request is detected information, the control module makes the line driver module work in a normal state; if the line deactivation information is detected, the control module makes the line driver module work alternately in ...

Abstract

The embodiment of the invention provides a method for reducing power consumption of a digital user line, which is applied to the field of digital user line. A line driver is driven to be alternately operated in a low power consumption state and a normal state, and a digital signal processor DSP detects information transmitted by the line and controls the line driver to change the operating state according to the detected information, so that the method can reduce the power consumption of the digital user line and save energy consumption. The embodiment of the invention also provides a device and a system for reducing the power consumption of the digital user line.

Description

technical field [0001] The invention relates to the field of digital subscriber lines, in particular to a method, device and system for reducing power consumption of digital subscriber lines. Background technique [0002] Digital Subscriber Line (Digital Subscriber Line, DSL) technology is a high-speed transmission technology for data transmission through telephone twisted pair, namely Unshielded Twist Pair (UTP), including Asymmetrical Digital Subscriber Line (Asymmetrical Digital Subscriber Line) Subscriber Line (ADSL), Very-high-bit-rate Digital Subscriber Line (VDSL), ISDN Digital Subscriber Line (IDSL) based on Integrated Services Digital Network (ISDN) ) and Single-pair High-bit-rate Digital Subscriber Line (Single-pair High-bit-rate Digital Subscriber Line, SHDSL), etc. [0003] Such as figure 1 The signal processing device shown includes a digital signal processor (Digital Signal Processor, DSP) module, a line driver Line driver module, an analog front end (Analogy...
