Problems solved by technology

[0002] Now there are a large number of DSL (Digital Subscriber Loop) users using DSL. According to statistics, 95% of DSL users usually have no data, but the DSL line is still running at full speed. resulting in huge power consumption
However, there is no power management for the data transmission of DSL, so as to reduce the consumption of electric energy, and the method of reducing the problems caused by electric energy consumption, such as heating and electromagnetic interference.

Embodiment Construction

[0026] The specific implementation steps of this method are described below in conjunction with the drawings.

[0027] This method is to solve the problem that the DSL central office (ATU-C) and user end (ATU-R) consume less or no data at the full rate mentioned above. Through this method, the DSL The user end and the central office can enter different power management modes according to the usage of the DSL line. In order to facilitate the implementation, we divide the power management modes into three situations to describe, 1, full rate mode (L0), 2, low power mode (L2), 3, idle mode (L3). The L0 mode mentioned above is the mode under normal operating conditions, L2 enters the power saving mode according to the rate of adjusting the link establishment, and L3 means that there is no data on the line, and neither the central office nor the user end transmits signals. Similarly, the data transmission flow and flow duration and the rate of link establishment can be adjusted and con...

Abstract

The invention discloses a management method for digital user's line loop power, including the following steps: setting a turning-up flow threshold, a turning-down flow threshold and a timer. The terminal of digital user line loop office real-time monitors the flow of data transmission. When data flow reaches the thresholds, it starts the timer. When the monitored data flow is more than the turning-up flow threshold all the time within the time-length of timer, the office terminal increases the transmission power to increase the rate of establishment of chains, and informs the user terminal. When the monitored data flow is less than the turning-down flow threshold all the time within the time-length of timer, the office terminal decreases the transmission power to decrease the rate, and informs the user terminal.

Description

Technical field [0001] The invention relates to a power management method, in particular to a digital subscriber line loop power management method. Background technique [0002] Nowadays, there are a large number of DSL (Digital Subscriber Loop) users using DSL. According to statistics, 95% of DSL users usually have no data, but DSL lines still run at full speed. This caused a huge consumption of electrical energy. However, there is no power management for the data transmission situation of DSL, so as to achieve the problem of reducing the power consumption, and the problems such as heat and electromagnetic interference caused by the power consumption can be correspondingly alleviated. Summary of the invention [0003] The technical problem solved by the present invention is to provide a digital subscriber line loop power management method, which can reduce the power consumption and reduce the heat and electromagnetic waves caused by the power consumption by performing power man...
