Description
Technical Field
The present invention relates to an apparatus for use in data communication. More particularly, the present invention relates to a dynamic management device for power consumption in the case of digital subscriber line communication and an application method thereof.
Background
Digital Subscriber Line (DSL) technology is a High-speed transmission technology for data transmission through twisted pair lines, and includes Asymmetric Digital Subscriber Line (ADSL), Very-High-rate Digital Subscriber Line (VDSL), single-wire-pair Digital Subscriber Line (SDSL), single-wire-pair High-rate Digital Subscriber Line (SHDSL), and the like. When a digital subscriber line is used, when a plurality of communication devices are integrated into a narrow case, on one hand, the consumption demand of a power supply is large, and great challenges are provided for a power supply system, and on the other hand, the heat dissipation conditions in the case are limited, a large amount of heat cannot be dissipated, and great influences are caused on the performance, reliability, service life and the like of the devices. The total energy consumption of China is the second worldwide and the population is the first worldwide. In order to save material resources and energy resources, a series of policy measures for promoting energy conservation and emission reduction are made in all industries in China. The broadband access network field is more sensitive to equipment power consumption due to the huge equipment deployment quantity. Therefore, controlling the power consumption of a single device in a range as small as possible is one of the key problems to be solved in single device development.
In the actual use process, when the whole device is powered on, the digital subscriber line is always in the full power consumption working state, and the power consumption cannot be dynamically managed according to the connection condition of the twisted pair side opposite end and the connection condition of the local end ethernet service data, so that the waste of the power consumption is caused. Although the digital subscriber line has low single-path power consumption, the local side equipment is often configured with multiple paths of board cards due to wide application and large quantity, so that the reasonable energy-saving design is adopted, and the overall energy-saving effect is very considerable.
