Method for realizing long distance controlled loopback of communication equipment

Abstract

This invention discloses a realization method for a communication equipment remote control loop which is to connect is series between it outside port and a user junction port, the said loop device controlled by the communication equipment has two states of loop back and through, when at the through state, output of the communication equipment port is connected with the input of the user junction port and output of which is linked to the input of the communication equipment port. When at the loop back state, output of the communication equipment port is connected with the said port input, realized by a relay, electronic switch or logic devices.

Description

Technical field [0001] The invention relates to a method for implementing loopback of communication equipment in a communication system. Background technique [0002] With the development of communication technology, more and more communication devices are used in communication networks. For example, Ethernet switches are increasingly used as users' access devices in broadband communities, which requires communication devices such as Ethernet switches. Can be installed and work normally in their respective environments. With the use of outdoor communication equipment, it becomes more and more important to conduct remote detection and monitoring of communication equipment to help locate equipment faults. [0003] In the maintenance process of the existing communication equipment, it is often necessary to loop back between different ports of the equipment to locate the fault or to judge the working status of the equipment. Most of the existing loopback methods are implemented by so...

Problems solved by technology

From the above process, it can be seen that the loopback method of the existing communication equipment loopback method is the internal self-loop of the chip, and the disadvantage is that the loopback coverage is small

by figure 1 For example, the range of remote control loopback that can be controlled by the control and switching circuits can only reach the physical chip level with loopback capability, and devices such as network port transformers that are further down do not have self-loop capability. The physical chip goes through the transformer to a section of blank area to the user port. The remote control loopback test of the above blank area cannot be realized by using the existing method. The remote control loopback test in the blank area is not only time-consuming and laborious, the real-time performance of the work is poor, and the efficiency of the loopback test is low
