摘要： A method and circuit are described for improving the pointer processing in the case of synchronous digital hierarchy (SDH) or synchronous optical network (SONET) transmission frames with VC4_4c, VC4_16c and VC4_64c concatenated payloads. The technique proposed by the existing Standards provides for two different state diagrams to be used in the pointer processing algorithm. One state diagram is used in the case of a concatenated payload and the other state diagram is used in the case of a non-concatenated payload. However, no solution is disclosed for automatically going from the states of one diagram to the states of the other diagram. The present invention provides a circuit so constructed that it can be used in an apparatus processing STM-4, STM-16 and STM-64 frames, through which the automatic recognition of the VC4-4c, VC4-16c and VC4-64c payload concatenation can be achieved. Therefore, it is not necessary to configure in advance the concatenation or non-concatenation condition.

摘要： A method for improving management of pointer processing for concatenated and/or not concatenated payload in SDH/SONET frames is described. The method comprises the steps of: receiving separate indications about the status of single tributaries, the indications comprising Normal State (NORM), Concatenated State (CONC), Loss of Pointer (LOP) and Alarm Indication Signal (AIS), processing, according to a pure combinatorial logic, the separate indications; and in case one of preset concatenation statuses is identified, such an identified current status of received flow of SDH/SONET frames is promptly declared or, in case no preset concatenation statuses are identified the tributaries are treated as stand alone. Differently from the prior art, the step of declaring a concatenation state is performed independently from a previously stored concatenation level.

摘要： A method of localizing failures occurring along a transmission path is provided. A data signal is transmitted along the transmission path, which comprises a path segment. A first network node performs a tandem connection monitoring source function of a tandem connection. A second network node monitors the transmission along the path segment, by performing a tandem connection monitoring sink function. When the first network node detects a failure of the data signal, the first network node enters information indicating a data signal failure into the data signal's overhead field. When the second network node detects a failure by the tandem connection monitory sink function, the second network node enters information into the overhead field. When a third network node detects a failure of the data signal, the third network node uses the information in the overhead field to determine whether the failure occurred within or outside of the path segment.
