The present invention provides a method and system in a Telecommunications Network for restoring Network Element failures or Network Link failures in case not all Network Elements possess distributed restoration capabilities, for examp le during an introduction-phase of the distributed restoration system, or in case a network consists of different kinds of Network Elements provided by different providers (multivendor network). The distributed restoration of Network Elements which do not possess these capabilities is taken over by the distributed restoration module of network management. This module then takes care of the part of the path set-up which would have been covered by the Network Elements restoration module The invention also includes a framework which facilitates provisioning of the restoration system in the modular way, which means that the operator can choose which kind of algorithm is the most suitable one in his situation. The interface which is used for communication between a Network Element and the Network Management, is implemented according to the q3 standard. The distributed restoration module within the Network Management can be replaced by a central restoration module which has the advantage over the distributed module that a better solution will be found.
