摘要： Signal format conversion apparatus and methods involve converting data signals between a first signal format associated with a first reference clock rate and a second signal format that is different from the first signal format and is associated with a second reference clock rate different from the first reference clock rate. A period of the second signal format is changed to match a period of a third signal format by controlling a synchronized second reference clock rate that is applied in converting data signals between the first signal format and the second signal format. The synchronized second reference clock rate is different from the second reference clock rate and is synchronized with a third reference clock rate. The third reference clock rate is associated with the third signal format. Such synchronization simplifies conversion of signals between the second and third signal formats.

摘要： Despite a recent revision, IEEE 1588™-2008 does not provide a complete implementation for PTP (precision time protocol) that accounts for variable delays introduced by network components. According to a broad aspect, the present disclosure provides implementations that account for variable delays introduced by network components. Therefore, the amount of time that a packet spends in transit through a transparent clock can be accounted for. According to another broad aspect, there is provided a master-slave mode that allows a transparent clock to function as a master or a slave to another clock.

摘要： A method of manufacture a transport network system includes: receiving input data having an input encoding; generating encoded data, having a transcode encoding, from the input data; generating an error correction redundancy for the encoded data; and sending an output frame, having the encoded data and the error correction redundancy, for increasing a net coding gain of the output frame based on the transcode encoding and the error correction redundancy.
