Abstract
A communications system comprising a plurality of islands, a media path comprising resources for carrying data in a plurality of calls between first and second ones of the islands in which each of the first and second islands comprises control means for managing allocation of the resources of the media path between the plurality of calls; in which the system also comprises means for detecting a faulty control means and either replacing the faulty control means with a working replacement control means or recovering the faulty control means to working order; in which the system also comprises means for providing from a further control means to the replacement or recovered control means on replacement or recovery information on the allocation of the resources of the media path.
Claims28
A communications system comprising a plurality of islands, a media path comprising resources for carrying data in a plurality of calls between first and a second ones of the islands in which each of the first and second islands comprises control means for managing allocation of the resources of the media path between the plurality of calls;
- in which the system also comprises means for detecting a faulty control means and either replacing the faulty control means with a working replacement control means or recovering the faulty control means to working order;
- in which the system also comprises means for providing to the replacement or recovered control means on replacement or recovery information on the allocation of the resources of the media path.
The system of any above claim in which the source of the information to be provided is located in the other one of the first and second islands from the replacement or recovered control means.
The system of any above claim in which the system also comprises means for co-ordination of the operation of the control means by communication between islands.
The system of any above claim in which the plurality of islands are interconnected via a backbone network in which the replacement or recovered control means is in a different island from source of the information to be provided.
The system of any above claim in which the media path comprises at least in part a blocking section and in which the replacement or recovered control means is separated by the blocking section from the source of the information to be provided.
The system of any above claim in which the replacement or recovered control means is connected via a router to the source of the information to be provided.
The system of any above claim in which the source of the information to be provided comprises a further control means.
The system of any above claim for carrying voice traffic as voice over internet protocol (VoIP).
A method of managing communications in a communications system comprising a plurality of islands and a media path comprising resources for carrying data in a plurality of calls between first and second ones of the islands in which each of the first and second islands comprises control means for managing allocation of the resources of the media path between the plurality of calls;
- the method comprising the steps of detecting a faulty control means and either replacing the faulty control means with a working replacement control means or recovering the faulty control means to working order;
- providing to the replacement or recovered control means on replacement or recovery information on the allocation of the resources of the media path.
