Described is a method for managing multiple failures of different type in telecommunications networks with a ring topology, in particular four-fiber transoceanic MS-SPRING rings. The method is characterized by providing at least one additional event signalling bytes in the transmitted frames, the first pair of bytes being used for signalling events of a first type, whereas the at least one additional pair of bytes being used for signalling events of a second type. Typically, the first pair of bytes is exclusively used to signal ring (or span) events, whereas the additional pair of bytes is exclusively used to signal span (or ring) events.
A method for managing situations of multiple events of different type in a telecommunications network with a ring topology protected by a traffic protection mechanism in which signals arranged as frames of bytes are transmitted and in which the transmitted frames comprise a pair of event signalling bytes, wherein the method further comprises the step of providing at least one additional pair of event signalling bytes in the transmitted frames, the first pair of event signalling bytes being used for signalling events of a first type, whereas the at least one additional pair of event signalling bytes being used for signalling events of a second type.
A method for managing situations of multiple events of different type in a ring topology telecommunications network protected by a traffic protection mechanism, frame arranged signals travelling through said network, said network comprising:
A signal frame structure for telecommunications comprising a first pair of bytes used for signalling events, wherein it further comprises at least one additional pair of bytes used for signalling events, the first pair of bytes being used for signalling events of a first type only whereas the at least one additional pair of bytes being used for signalling events of a second type only.
A network element for a telecommunications network with a ring topology protected by a traffic protection mechanism, signals arranged as frames travelling through said network, said network comprising:
