Trouble shooting method and equipment for link plugboard with SDH interface

Abstract

The present invention provided a trouble shooting method and equipment for link plugboard with SDH interface. The basic idea is provide several spare boards at least on thereof being associated to a different chain of boards. By connecting the spare boards of the different board chains, a pool of spare boards is obtained. Thus, the associations of the spare boards to respective chains are, at least virtually, resolved allowing to employ the spare boards for healing of failures for any of the boards in the different chains. In particular, the present inventions allows a healing of several failures independently of the location of a failure in the chains. The number of spare boards in the different chains determines the number of pool spare boards and, thus, the minimum number of failures which can be healed. In order to increase the number healable failures, the number of spare boards in the different chains can be increased. Further, it contemplated to operate and to re-configure at least one of the board(s) originally forming one of the different chains, spare board(s) already used for failure healing and chain(s) such that an increased number failures are compensated without the need for an increased number of spare boards.

Description

[0001] The present invention is based on the prior application EP02 360 031.5, which is hereby incorporated by reference. technical field [0002] The present invention relates to methods and devices for enabling data service components to operate in a communication environment. In particular, the present invention relates to repairing and compensating for failures of data service components operating in a chain connection in a communication environment. Background technique [0003] The expansion of the scope of telecommunications, especially the increase in the volume of data traffic and the increase in the number of participating systems and devices requires higher performance of hardware for transmitting data traffic. Especially in the field of 2G and 3G, as the traffic volume is expected to increase significantly, operators of the telecommunications environment need efficient, high-performance equipment that is not sensitive to failures and errors. [0004] In order to...

AI Technical Summary

Problems solved by technology

[0008] However, due to the increased complexity of such an enhanced communication environment, some parts and especially some of its components are prone to failure and errors

Therefore, such an enhanced communication environment may be less reliable and stable than previous solutions, while failures and errors may have a greater impact, for example, on components with high data traffic rates

A particular problem with boards operating in a chain connection is the failure of a series of subsequent boards

Moreover, multiple successive alarms, especially from several boards, due to a single fault can overwhelm the human and technical staff

Therefore, the traditional fault detection, which can also be performed by timers, is too long for SDH, and for high data traffic rates, it takes up extra technical and human resources
