Problems solved by technology

[0006] ① The cost of the tester is too high. This is because the product is in the production duplication stage, and there are many similar products that need to be debugged. In this way, the cost issue must be carefully considered, so the cost of batch testing is very high
[0007] ②The ATM ports supported by many testers are limited, and the optical fiber needs to be plugged and unplugged many times during the test, which reduces the test efficiency and is not suitable for the test requirements of mass production
[0008] ③ The intervention of external instruments requires a corresponding improvement in the quality of testers, which virtually ...

Embodiment Construction

[0029] The present invention will be described in further detail below through specific embodiments and in conjunction with the accompanying drawings.

[0030] See figure 2 , the program only needs a PC computer, an ATM test card designed and developed by itself, the ATM switch to be tested, and several cables. The test card can be inserted into a PC computer, and can provide high-speed (155M / 622M / 2.5Gbit / s) service flow, test the bit error rate of each port of the switching network board, and count the number of sending and receiving and error cells. Based on the hardware of the card, related software has been developed to realize the functions of generating, sending, receiving, counting, comparing and reporting errors, and setting the working mode of the test card.

[0031] Such as figure 2 As shown, according to the figure, use a cable that meets the electrical characteristics of each port to send and receive an external loopback between this port and the next port, and...

Abstract

The present invention discloses a business intercommunication test method and device for asynchronous transferring mode exchange. Test business flow is made to traverse all exchange channels, and theATM test card compares the final business flow with the initial business flow, counts and judges the cell loss and error data, and reports the test result. The present invention solves the problem ofdata source in high-speed cell business flow test and can perform the high-load business test of exchanger. The business flow produced by the test device may be exchanged to all channels without testleakage. The present invention may be used in high-efficiency automatic test.

Description

Technical field: [0001] The invention relates to a method and a device for testing service interworking of an asynchronous transfer mode (ATM) exchange. Background technique: [0002] With the continuous increase of transmission rate and switching capacity, the design of ATM broadband switches has become increasingly complex, so the production test of this kind of broadband switching products is also facing increasingly severe challenges, and the most difficult and most important in the production system level test The most important is the business interoperability test, which is to test the business interoperability between each board of the product, and also to test the switching capability of the entire switch. This test item is a key point for a comprehensive inspection of the entire ATM switch before delivery, and its significance can be imagined. [0003] Such as figure 1 As shown, the ATM broadband switch has three parts: the switching unit, the interface unit and ...
