摘要： A method and circuit for mismatch detection in SDH-coded frame trace identifiers within a telecommunication network, wherein received trace identifiers are compared with expected trace identifiers in determined locations of the communication network, to detect if a misconnection event has occurred and generate a corresponding alarm signal. The method comprises the steps of: a) validating the received trace identifier (TI) and issuing a corresponding validation signal (CRC7, CNST); b) comparing the received trace identifier (TI) with an expected trace identifier (ETI) and issuing a corresponding validation signal (MTC1, MTC16); c) evaluating the validation signal (CRC7, CNST) and the match signal (MTC1, MTC16); and d) generating a matching state signal (SVAL1, SVAL16) according to the result of the evaluation as per step c), wherein steps a) and b) are executed in parallel.

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.
摘要翻译：描述了在具有VC4_4c，VC4_16c和VC4_64c级联有效载荷的同步数字层级（SDH）或同步光网络（SONET）传输帧的情况下改进指针处理的方法和电路。现有标准提出的技术提供了在指针处理算法中使用的两种不同状态图。在连接的有效载荷的情况下使用一个状态图，而在非并置有效载荷的情况下使用另一个状态图。然而，没有公开用于自动从一个图的状态到另一个图的状态的解决方案。本发明提供了一种如此构造的电路，其可用于STM-4，STM-16和STM-64帧的装置处理，通过该电路自动识别VC4-4c，VC4-16c和VC4-64c有效负载级联可以实现。因此，不需要预先配置级联或非级联条件。

摘要： Proposed is a method of decoding a differentially encoded PSK modulated optical data signal carrying FEC encoded data values. The optical signal is corrected by an estimated phase offset. From the corrected signal, respective likelihood values for the FEC encoded data values are derived, using an estimation algorithm which accounts for a differential encoding rule used for differentially encoding the optical signal. The derived likelihood values are limited to a predetermined range of values. From the limited likelihood values, FEC decoded data values are derived, using an algorithm which accounts for a FEC encoding rule used for FEC encoding the FEC encoded data values.
