Problems solved by technology

The disadvantages are: depending on the system environment, inconvenient operation, NT1 needs to be reset before each activation process, resulting in long test time and low test rate
If these dedicated testers are used to build a production test environment for the U port of the user board, of course the U port test can also be completed, but if it is used for production test or maintenance test, there is still a long process of U port activation and a high degree of manual participation. The disadvantage of low efficiency

Embodiment Construction

[0023] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0024] Fig. 1 is a schematic diagram of the system connection of the test method proposed by the present invention. As shown in FIG. 1 , each U port of the board under test (ISDN user board) 101 is connected to the test environment through cables. The test environment 102 realizes the access of each U port. In practical applications, 1 to N U ports are respectively connected to each U port of the board under test through cables. Since the board under test and the test environment are very close, the connecting cables There are no special requirements.

[0025] Figure 2 is a functional block diagram of the test environment. As shown in FIG. 2 , the environment is composed of N U ports 201 , a dedicated U interface chipset 202 , a data analysis and processing module 203 , and a control module 204 . N U ports 201 are physical interfaces of N U...

Abstract

The method for testing U port of ISDN user board includes such steps as initializing testing environment and ISDN user board sending command for testing U port of ISDN user board to be tested from testing environment sending command for activating M and appending 2B+D information from each U port of board to be tested receiving the information and separating information of M, B, D channels of U port by testing environment testing environment parses M signal determining whether M signal is a activated signal determining whether the tested board receives M response signal and B, D signal the advantages are high efficiency, and low cost.

Description

technical field [0001] The invention relates to the testing field, in particular to a method for testing a U port on an ISDN user board. Background technique [0002] ISDN network, that is, integrated services digital network, has been widely used since the 1990s. ISDN can absorb and integrate various existing public network services, and process various communication services in a unified digital form. As long as an ISDN switching module that can be connected to various communication networks is installed and a standard user-network interface is provided, users can communicate with various communication media through one subscriber line. At present, ISDN has become one of the main means of transmitting integrated services such as voice, data and images, and it is also the starting point for developing the information superhighway. [0003] The U interface is an application interface of the ISDN network. The ISDN network is connected to the network type terminal 1 (NT1) th...
