Problems solved by technology
[0004] Due to the lack of continuity and low test frequency of the stability test by manual operation, the results of the stability test are also discounted accordingly, and it is time-consuming and laborious, so it is not recognized. Using the large-capacity DSL port characteristic test instrument provided by the test equipment manufacturer is Test equipment with terminals, but the rapid development of DSL technology, the test equipment cannot flexibly replace the terminal, and truly simulate the user terminal, resulting in the terminal not being able to keep up with the development of DSL technology in time, which hinders the stability test

Embodiment Construction
[0042] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0043] The main idea of the present invention is to complete the test of the stability of the large-scale DSL port establishment and disconnection through the large-scale DSL port establishment and disconnection stability test system. The large-volume DSL port establishment and disconnection stability test system includes a subscriber line convergence board , user port switch control board, DSL central office equipment, test equipment, stability test control platform, etc., among which,
[0044] The subscriber line aggregation board is used to aggregate the subscriber lines into one cable through the subscriber line aggregation board for the DSL MODEM (modem) forming the large-capacity test DSL port;
[0045] The user port switch control board is connected in series between the user line aggregation board and the equipment user board, and is ...

The invention discloses a system and a method for testing stability of linking / link-breaking of a large quantity of digital line ports. The system comprises a user line convergence board for converging a DSL MODEM for constituting a high-capacity test DSL port to a wire cable; a user port switch control board cascaded between the user line convergence board and a device user board for controlling switch operation of a user port; and a stability test control platform for controlling a user port switch control board and controlling a test device for transmitting data flow so that a large amount of data flow is transmitted between a DSL optical line terminal and an exchange so as to implement stability test of linking / link-breaking of a large quantity of digital line ports. The system enables a user port switch control board hardware circuit to control the user's switch by adding the user port switch control board and leads to an automatic test, thus ensuring a rapid execution of a control command and improving the testing strength and quality.
Description
technical field [0001] The invention relates to a DSL (Digital Subscriber Line) equipment user port characteristic testing technology, and more specifically relates to a system and a method for realizing a large-scale link establishment and disconnection stability test for DSL user ports of DSL central office equipment. Background technique [0002] With the rapid development of the Internet, various DSL technologies have been fully developed, and the number of DSL users has also shown explosive growth. The newly developed DSL central office equipment has also increased in large numbers, and the stability test of large-scale DSL port establishment and disconnection Methods and means can not keep up with the development of the form, which restricts the stability test of the user board of the DSL central office equipment. [0003] At present, there are mainly two types of methods used to realize the stability test of link establishment and disconnection of a large number of DS...
