Embodiment Construction

[0024] The present invention will be described in further detail below in conjunction with the accompanying drawings (embodiments):

[0025] refer to Figure 1A~Figure 7 , the present invention consists of 1~32 wire selection frames LAMS, each wire selection frame LAMS is equipped with a motherboard LAMM; a communication control, self-test and power supply board CTP is installed; 18~19 16-wire wire selection boards L16; 32-way line selection matrix board M32; two sets of terminal emulation point boards TE2; short-circuit connector SHC and passive self-test connection board STC are inserted into the socket on the back of L16.

[0026] figure 1 Among them, 16~304 lines use one test head.

[0027] In Figure 2, 305~9216 lines, 1~32 test heads (usually only 1~several) are used, and the test heads can be flexibly allocated to test 32 frames.

[0028] image 3 Among them, more than 9216 lines, use multiple sets of the above-mentioned systems in Figure 2 to connect with M32 casca...

Abstract

A matrix for selecting lines of 112 testing platform is characterized in that it is constituted by 1-32 frames LAMS for selecting lines, on which each are mounted a master board LAMM for selecting lines, a board CTP for communication controlling, self-testing and power source, 18-19 boards L16 for selecting 16 lines and a matrix board M32 for selecting 32 lines. The connectors for shorting SHC and passive connecting board STC for self-testing are inserted in the shocket positioned in the back of the board L16 for selecting 16 lines. This invention can ensure that the switching-in does not affect the current operation, and any circuit board can be inserted in and pulled out in hot-line without impairment to normal operation.

Description

Technical field [0001] The present invention relates to a matrix, in particular to a 112 test table line selection matrix. Background technique [0002] The Telecom 112 test bench needs to test the central office and customer end equipment and subscriber lines to determine the fault. In recent years, with the development of broadband network, there are more and more ADSL users. The original 112 test station cannot test ADSL, so it needs to be equipped with a dedicated ADSL test head. In order to test a large number of users with a small number of test heads, it is necessary to use a front end The line selection relay matrix. However, imported equipment is expensive, and the circuit board cannot be plugged or unplugged. [0003] Purpose of invention [0004] The purpose of the present invention is to provide a circuit board that can be plugged and unplugged under power without affecting the normal use of users. The minimum capacity is that one test head serves 304 users, a...
