Remote electric power supplying system and its control

Abstract

The system thereof comprises: a power supply at central office end for providing power for remote power consumer at remote end. Said power supply comprises: central office monitoring module and central office power module. A remote end monitor is set in the remote power consumer. Said remote end monitor monitors the on-line state of said remote power consumer, and sends the monitor signal to said central office monitor module. By the monitor signal from the remote monitor, the central office monitor module controls the central office power supply module to provide power for the remote power consumer.

Description

technical field [0001] The invention relates to a power supply technology in a communication system, in particular to a remote power supply technology in a communication system. Background technique [0002] With the rapid development of network communication systems, remote power supply systems have become an important technology in expanding communication services. For example, in the case of the ever-increasing demand for XDSL (X Digital Subscriber Line) services, a relatively common method to expand new services to end users on the basis of the existing digital subscriber line network is: to use DSLM ( DSL Access Multiplexer, DSL access multiplexer) equipment is more moved to the end user side. In this way, 1-2 pairs of twisted pairs or coaxial cables can be used as the uplink channel, and more users and services can be accessed through the DSLM equipment. Since the environment on the user side is complex and it is inconvenient to provide power in most cases, moving th...
