Multifunctional circuit test board of voice terminal equipment

Abstract

The invention discloses a multifunctional circuit test board of voice terminal equipment, relating to the field of circuit test in optical fiber communication. The multifunctional circuit test board comprises a first Tip wire, a first Ring wire, a second Tip wire, a second Ring wire, a fire wire, a ground wire, a zero wire, a Tip power switch, a Ring power switch, a Tip hybrid wire switch and a Ring hybrid wire switch, wherein the power switches are arranged on the fire wire, and the first Tip wire and the fire wire are connected with the Tip power switch; the Ring power switch is connected with the first Ring wire and the fire wire; the Tip hybrid wire switch is connected with the first Tip wire and the second Tip wire; and the Ring hybrid wire switch is connected with the first Ring wire and the second Ring wire. The multifunctional circuit test board can be used for testing the extended items, such as the electric wires, hybrid wires, earth atmosphere, electricity leakage and REN and judging the state of a tested voice port, thereby remarkably shortening the testing time of a circuit in a laboratory, improving the testing efficiency and accuracy and being safe in test process; and the multifunctional circuit test board is convenient for storage and batch production.

Description

technical field [0001] The invention relates to the field of line testing in optical fiber communication, in particular to a multifunctional line testing board for voice terminal equipment. Background technique [0002] Operators in the field of optical fiber communication gradually require the voice terminal equipment provided by the manufacturer to have the function of line test. When the user's telephone service fails, the fault can be quickly and remotely located, which is not only conducive to the rapid resolution of the fault, but also saves labor costs. Before a voice terminal device is applied, it needs to conduct self-test in the laboratory, including self-test by R&D personnel and pilot test. [0003] Voice telephone lines are divided into Tip line (positive line) and Ring line (negative line). For various situations that may be encountered in practical applications, the line test items should not only include basic off-hook, on-hook, and circuit breaks, but also ...

AI Technical Summary

Problems solved by technology

[0005] (1) The current manual temporary wiring method only supports some simple and basic line function test items, and cannot simulate some special situations that may be encountered in actual applications, resulting in the inability to accurately determine the root cause of voice line failures in actual applications, delaying Troubleshooting

[0006] (2) Various tests are carried out through manual temporary wiring. Not only is the workload heavy, the test time is long, the speed is slow, and the efficiency is low. It is also easy to cause poor line contact due to manual wiring errors, which will affect the accuracy of the test results.

[0007] (3) There is no safety guarantee during the test. For example, in the test of touching the power line, the tester is likely to cause personal danger due to touching the high-voltage power line

[0008] (4) The current test tools are relatively scattered, inconvenient for storage, and cannot be mass-produced, and the economic benefits are not high
