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

Embodiment Construction

[0049] In the following, the present invention will be described by taking a telecommunication environment using the Synchronous Digital Hierarchy (SDH) standard as an example. Since SDH is well known in the technical field, the detailed description related to SDH is omitted.

[0050] see figure 1 , a telecommunications environment includes a network for data communication with other networks (eg, mobile and fixed telephone networks), end-user equipment (eg, telephones, computer systems), communication systems (eg, Internet servers), and the like. For data communications, the different parts of this telecommunications environment are linked by hardware interfaces. In the case of SDH, such an interface is formed by the device providing the SDH interface.

[0051] figure 2 Such an interface means linking a mobile telephone environment and associated terminals to a wired telephone environment is shown as an example. The mobile telephone environment is connected to the interf...

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...
