A method for realizing vectoring VDSL2 service in vdsl2 system

Abstract

The invention discloses a method for realizing Vectoring VDSL2 services in a VDSL2 system. Set as a vectoring processor, the DSP module sends a clock receiving control signal to the clock control circuits of different business machines through the clock control circuit of the same business machine disk, controls the corresponding clock circuit to receive the clock signal; Send clock and send control signals; the vectoring processor sends clock signals to other DSP modules through the clock circuit of the business machine disk, and other DSP modules receive the clock signal through the clock circuit on the business machine disk to realize the clocking of all DSP modules in the system. Synchronize. The present invention reduces one central vector computing board, reduces the manufacturing cost and overall power consumption of the VDSL2 system, reduces energy waste, and realizes green and energy-saving communication.

Description

technical field [0001] The invention relates to the field of VDSL with vector operation, in particular to a method for realizing Vectoring VDSL2 service in a VDSL2 system. Background technique [0002] In recent years, with the advancement of the broadband speed-up project, many residential areas have carried out the transformation of light-in and copper-out, but through practice, people found that in many old communities connected by copper cables, due to problems such as property coordination and users' reluctance to change home decoration, As a result, the difficulties and more than 75% of the cost of the entire transformation are in the fiber optic cable home section; according to statistics, such communities that are not suitable for optical transformation account for more than 50% of the total transformation of the community, while 82.6% of the existing copper cable network stock in China is copper The service life of the cables is ≤20 years, of which 70% of the copper...

Problems solved by technology

[0005] In most engineering application scenarios, one of the above-mentioned remote ONU devices will only be equipped with 2 or 1 VD32 service disk, but in order to open the vectoring VDSL service, a central vector computing disk must still be configured. In this case, It will lead to an increase in equipment cost and power consumption. Considering that in the actual project at this stage, the vectoring VDSL service needs to be opened, and the number of equipment applications that will only be equipped with 2 or 1 VD32 service machine disks will be large. energy waste, which is contrary to the energy conservation and emission reduction policy advocated by the state, and does not match the energy conservation and emission reduction goals of the three major telecom operators
