Embodiment 1

[0054] In this embodiment, the reverse power supply management solution provided by the embodiment of the present invention is described by taking the reverse power supply power distribution as an example.

[0055] Figure 4 is the flow chart of the reverse power supply power distribution in this embodiment, such as Figure 4 It mainly includes the following steps:

[0056] Step 401, each terminal device connected to the central office device stably supplies reverse power to the central office device.

[0057] Step 402, the central office device obtains the reverse power supply capability information of each terminal device through the PoE (PoweroverEthenet) protocol.

[0058] Step 403, the central office equipment acquires the length and impedance characteristic information of each link through the initialization process.

[0059] Step 404, the central office device obtains the power status and service status information of each terminal device through the management chann...

Embodiment 2

[0065] This embodiment is described by taking the reverse power supply enabling management as an example.

[0066] Figure 5 The flow chart of the reverse power supply enable management in this embodiment is as follows Figure 5 It mainly includes the following steps:

[0067] Step 501, each terminal equipment connected to the central office equipment stably supplies reverse power to the central office equipment;

[0068] Step 502 , when a certain terminal device has no service or switches to a battery-powered state, the central office device transmits the enable signal Power-Off to the terminal device through a management channel (eg, an eoc command (embedded operation channel)).

[0069] Step 503, after receiving the enable signal, the terminal device turns off the power output of its reverse power supply module, and stops reverse power supply to the central office device.

Embodiment 3

[0071] This embodiment is described by taking the reverse power supply time management as an example.

[0072] Image 6 The flow chart of reverse power supply time management in this embodiment, as Image 6 It mainly includes the following steps:

[0073] Step 601, each terminal equipment connected to the central office equipment stably supplies reverse power to the central office equipment;

[0074] Step 602, the central office equipment obtains the length and impedance characteristic information of each link through the initialization process.

[0075] Step 603, the central office device obtains the reverse power supply capability information of each terminal device through the PoE (PoweroverEthenet) protocol;

[0076] Step 604, the central office device obtains the power status and service status information of each terminal device through the management channel;

[0077] Step 605, the central office equipment determines which link terminal equipment participates in rever...

Abstract

The invention discloses a reverse power supply management method, device and system. The method comprises steps of obtaining reverse power supply information of terminal equipment of each link when each terminal equipment connected with central office end equipment steadily performs reverse power supply to the central office end equipment; determining reverse power supply management information of each terminal equipment according to the obtained reverse power supply information of the terminal equipment of each link; and sending the reverse power supply management information of each terminal equipment to the corresponding terminal equipment, indicating each terminal equipment for adjusting reverse power supply parameters for the central office end equipment according to the received reverse power supply management information.

Description

technical field [0001] The present invention relates to the field of communications, and in particular, to a method, device and system for reverse power supply management. Background technique [0002] With the rapid development of science and technology, Digital Subscriber Line (DSL) technology can provide voice, video and data services over ordinary twisted-pair wire pairs. full utilization and safe use. [0003] At present, the latest G.fast technology can provide asymmetric transmission with an uplink and downlink net rate of up to 1Gbps on the twisted pair by expanding the spectrum. [0004] figure 1 It is a schematic diagram of G.fast supporting reverse-powered fiber-to-the-distribution point (FTTDP). like figure 1 As shown, the central office equipment of the fiber-to-distribution point (DP) is usually deployed in the basement of the house or at the wiring hole. Due to the complexity of the access environment, it is difficult to supply power to the equipment. If ...
