Problems solved by technology

In the limited time, only a certain port in the DSLAM equipment user board can be carefully tested, and the possibility of missing problems is high
[0007] (2) Some problems can only appear after increasing the distance and maintaining it for a period of time, such as a broken link in a few hours
When testers use manual configuration, because the test is car

Example Embodiment

[0067] Such as figure 2 As shown, the network construction method of the test system of the present invention can be as shown in the figure, including the modem 22 to be tested, the line simulator 23, and the digital subscriber line access module 24 connected to the test computer 21, and the line simulation The meter 23 is also connected to the modem 22 and the digital subscriber line access module 24 respectively. The test computer 21 serves as the console of the entire test system, performs related control and operation of the test, and controls the modem 22 and the digital subscriber line access module 24 to automatically collect and save test data.

[0068] In such figure 2 In the test environment shown, running the test script written according to the test method of the present invention can automatically complete related tests and the collection and storage of test data. Next, the DLS400 line meter will be used as a line simulator to simulate a specific distance and noise ...

Abstract

The invention relates to modem automation testing method and testing system. The method includes the following steps that connecting the modem to the circuit simulator and the correlative testing device to form a testing environment and open the corresponding communication control port; controlling the circuit simulator and simulating the given distance and the noise environment; controlling the tested device to do testing operation and extract the performance testing result from it. The invention combines the circuit simulator, the operation of the DSLAM device and the testing data extracting to a automation script running to avoid great hand operation, realize the adding-distance adding-noise automation testing of the modem.

Description

technical field [0001] The invention relates to an automatic test method and a test system for the transmission performance of communication equipment, in particular to a test method and a test system for several indicators stipulated by national standards in the transmission performance test field of a modem (MODEM). Background technique [0002] According to YDT1055-2000 "Asymmetrical Digital Subscriber Line (ADSL) with Voice Separator" to test ADSL equipment is the current Chinese national standard and the industry standard of the communication industry. The performance test of ADSL equipment in this standard stipulates two types of line tests based on Europe and North America. Usually, the performance, signal-to-noise ratio and attenuation under 10 different loops and noise environments are tested. If impulse noise and voice are considered Interference, 18 kinds of loop and noise environments need to be tested. [0003] In fact, in this test, it is usually tested by man...
