Embodiment Construction

[0046] see image 3 , is a connection schematic diagram of an FXS interface test system of the present invention, the FXS interface test system includes a passive FXS test auxiliary device 10 and a device under test 20 .

[0047] As everyone knows, the FXS interface and the FXS interface cannot be directly connected, but can only be connected with the FXO port equipment or an interface similar to the FXO port, but after adding a passive FXS test auxiliary device 10 of the present invention, the FXS interface and FXS interface connected. When FXS1 and FXS2 are connected into one channel, when testing FXS1, you can use FXS2 as a test device, and when testing FXS2, use FXS1 as a test device. This saves expensive test equipment with FXO interfaces. Then, the test of the FXS interface is automatically completed according to the software preset process.

[0048] In this embodiment, the passive FXS test auxiliary device 10 includes a telephone interface 1 and a telephone interface...

Abstract

The invention provides a system and a method for testing an FXS interface. In the system and the method, passive FXS test auxiliary equipment is provided to connect two interfaces, such as FXS1 and FXS2, in the FXS interface, so that FXS2 is used as test equipment when the FXS1 is tested and the FXS1 is used as test equipment when the FXS2 is tested. Thus, the use of expensive test equipment withan FXO interface is avoided. Then, the test of the FXS interface is automatically completed according to a preset process in software, and each tested FXS interface can realize ringing, off-hook, DTMF signal transmission and DTMF signal reception and other processes. The system and the method have the advantages of reducing signal FXS interface test cost due to the synchronous test of two FXS interfaces by using the FXS interface of the product, improving automatic test degree, avoiding the use of a large amount of human interference, along with simple structure, low cost and suitability for batch production.

Description

【Technical field】 [0001] The invention relates to an integrated access device with a simulated user interface, in particular to a FXS (Foreign Exchange Station, foreign exchange station) interface test system and test method. 【Background technique】 [0002] FXS (Foreign Exchange Station) is a voice interface, a line-side connection between a digital telephone switching system and a POTS telephone. It is widely used in digital program-controlled switches or other integrated access equipment. How to realize the automatic test of FXS interface has become an urgent problem to be solved in production. With the increase of the number of interfaces, a large number of test instruments are needed for the factory inspection of products. [0003] In the current test environment of the application, the test can be carried out manually, that is, no additional equipment is required, and only manpower is required to test each FXS interface for ringing, off-hook, and conversation, but many...
