    • In order to improve the link adjacency discovery in an Optical Transport Network, a method and related network nodes are provided. A first network node (21) has a first discovery agent (216) and a second network node (22) has a second discovery agent (226). A discovery message (210) is transmitted from a first interface of the first network node (21) over one or more subsequent network links (25, 26, 27) to a second interface of the second network node (22). The discovery message (210) contains information indicative of an discovery agent identifier associated with the first discovery agent (216) and of a termination connection point identifier associated with the first interface. In order to transmit the discovery message (210), the first interface is configured to perform a tandem connection source function (217) using a reserved field in an overhead portion of signal frames to be transmitted. The second interface is configured to perform a Tandem Connection Monitoring function (227) on the same reserved field of received signal frames. The discovery message is sent using a Trail Trace Identifier (TT!) byte available in the reserved field.

    • Proposed is a method of deriving differentially decoded data values from a received differentially encoded phase modulated optical signal. The method uses an estimation algorithm in order to find derive a sequence of differentially decoded data values. The algorithm stipulates transition probabilities between hypothetical first states, representing differentially encoded data symbols assuming that no phase slip has occurred, and transition probabilities towards hypothetical second states, which represent differentially encoded data symbols assuming that a phase slip has occurred. The transition probabilities between the first and second states are weighted on the basis of a predetermined phase slip probability value.
