Abstract: Provided is a method for calculating a timestamp associated with a data packet before transcoding of the data packet. The method may include sampling a time of day (TOD) signal to provide a sampled TOD. A previously sampled TOD estimate may be retrieved. An internal TOD estimate may be determined based on the sampled TOD and the previously sampled TOD estimate. A timestamp may be determined based on the internal TOD estimate. A system and computer program product are also disclosed.

Abstract: A system for detecting a false linkup state in an Ethernet communication link includes at least one processor programmed or configured to determine a block type of a block of bits received from a serializer/deserializer (SerDes), increment a first counter based on determining that the block type of the block of bits corresponds to a data block type or an error block type, determine whether the first counter satisfies a first threshold, enable a flag indicating that there is a false linkup state in an Ethernet communication link, and transmit a message indicating that there is a false linkup state for the Ethernet communication link to an Ethernet network device that is a link partner of the Ethernet communication link. A method and a computer program product are also provided.
