Method and system for saving energy of user interface circuit

Abstract

A method for saving energy of a user interface circuit is provided by the present invention. The method includes: establishing a correspondence between a user line state and a feeding current parameter; detecting the user line state, and determining the feeding current corresponding to the present user line state according to the correspondence. A system for saving energy of the user interface circuit is also provided by the present invention. In the method and system the feeding current is set according to the correspondence between the user line state and the feeding current parameter, so that the feeding current can be appropriately set to match changes in the user line state, thus avoiding power dissipation problems caused by the constant feeding current, solving the difficult problem of setting the feeding current when the external line is unknown, and achieving the objective of saving energy and reducing emission, and increasing the working power utilization rate.

Description

technical field [0001] The invention relates to the field of communication equipment, in particular to a method and system for energy saving of a user interface circuit. Background technique [0002] Communication equipment that uses user interface circuits, such as switches running on PSTN (Public Switched Telephone Network, public switched telephone network), access gateway, IAD (Integrated Access Device, integrated access device), xPON (x Passive Optical Network, passive Optical network) terminals and DSL (Digital Subscriber Line, Digital Subscriber Line) terminals and other voice-related equipment, because of the high operating voltage, large current, and large quantity of user interface circuits, the power consumption is relatively large, which is the source of energy consumption. It is of great significance to energy saving and emission reduction. There are three ways to save energy and reduce consumption of existing user interface circuits: [0003] 1. Use a set of ...

Problems solved by technology

[0014] However, each user circuit may perform off-hook, on-hook or ringing operations at the same time. Therefore, in this solution, each user circuit needs to be fed separately, the feed power supply is controlled independently, and there are many separate components, which requires high production and reliability.

[0015] These three existing methods all have limitations. How to overcome their limitations to reduce the power consumption of the user interface circuit is of great significance to energy conservation and emission reduction. It is also a key factor for operators to reduce their huge electricity expenses and increase profit margins.
