Embodiment 1

[0045] Such as image 3 As shown, it is the test flow chart in the factory test, which specifically includes the following test steps:

[0046] a) Obtain the device under test equipped with the built-in storage device 2, and write complete test data or test software and expected performance data into the storage test unit 204 of the built-in storage device 2;

[0047] Specifically: the expected performance data is a mixture of basic expected data and customer-specified expected data;

[0048] Preferable: The basic expected data is based on the relevant recommendations and requirements of CCITT.

[0049] b) Start the external test device 1 and send simplified instructions to the built-in storage device 2;

[0050] Specifically: after the external test device 1 is started, the first control unit 101 controls the command generation unit 102 to generate a simplified command, which is then sent by the first sending unit 103 and received by the second receiving unit 202;

[0051]...

Embodiment 2

[0072] Such as Figure 4 As shown, it is the test flow chart in the maintenance test, which specifically includes the following test steps:

[0073] a) Start the external test device 1 to shield non-test commands;

[0074] Specifically: the masking unit 106 completes the masking operation, for example, cancels the detection of one or more items.

[0075] b) send the remaining simplified instructions;

[0076] c) The built-in storage device 2 receives simplified instructions and performs instruction matching;

[0077] d) Carry out directional test according to the instruction data matched in step c);

[0078] e) generate test data and simplify calculations;

[0079] f) return the simplified result;

[0080] g) End detection.

Abstract

The invention belongs to the technical field of data communication testing, and discloses a data communication tester, which comprises an external testing device and a built-in storage device arrangedin equipment to be tested, the external test device comprises a first control unit, an instruction generation unit, a first sending unit, a first receiving unit, a display unit and a shielding unit.The built-in storage device comprises a second control unit, a second receiving unit, a matching unit, a storage test unit, a comparison statistics unit, a simplified calculation unit and a second sending unit; the tester provided by the invention adopts a split structure form, and a simplified instruction can be adopted between the two split structures to transmit test data, so that the test datacirculation speed is effectively improved, and the purpose of improving the test efficiency of the tester is achieved; besides, the built-in storage device in the split structure can be set in a user-defined manner, so that the requirement of a specified test can be met, and the universality of the external test device is not influenced.

Description

technical field [0001] The invention belongs to the technical field of data communication testing, and in particular relates to a data communication testing instrument. Background technique [0002] Data communication test refers to testing whether the technical performance indicators of data circuits, data terminals and switches meet the relevant recommendations of CCITT; [0003] With the development of modern data communication technology, various devices with data communication functions are becoming more and more complex, and the test data flow in the corresponding equipment data communication test is also becoming more and more complex, which leads to the transmission speed of the test data flow being restricted. Greatly reduced, affecting the overall test efficiency; [0004] In addition, the specific performance requirements of communication equipment are different for different places of use or different receiving customers. For example, some customers require fast...
