Feed method, system and equipment

Abstract

The inventive embodiment provides a feed system, which comprises a power converter and a plurality of feed management systems. The power converter is connected with the feed management system, which supplies voltage to user loop through the feed management systems. The feed system also includes a loop information collecting unit and a control unit, the loop information collecting unit collects information of the user loop and transmits the information to the control unit; the control unit computes voltage value suitable for the user loop according to the received user loop information and outputs voltage information indicating the voltage value to the power converter; the power converter outputs voltage corresponding to the voltage value to the feed management system according to the received voltage information. The invention also provides a feed system and a communication equipment, which reduces cost and system power consumption.

Description

technical field [0001] The invention belongs to the field of electronic communication, and in particular relates to a power feeding method, system and equipment. Background technique [0002] POTS (Plain Old Telephone System, traditional old telephone system) service user board is used for the access of traditional telephone services at the central office, and access devices such as IAD (Integrated Access Device, integrated access device) provide access to traditional telephone services. The main unit of telephone service processing of access equipment such as POTS service user board and IAD is the power feed management system. [0003] In the past, due to the concentration of access devices, the distance between the user loops of each port on a user board was quite different; with the development of technology and the promotion of distributed access systems, the access devices are getting closer to the user side. Especially with the development of FTTx (Fiber to the x, fib...

AI Technical Summary

Problems solved by technology

However, the single board needs two power converters to handle the power feeding, which will increase the cost of the single board; at the same time, the two power converters will occupy more space on the single board, which is not conducive to the high-density design of the current communication system; The power management system must support two-way power input and switching, which will increase the cost of the equipment accordingly.
