Abstract
A physical layer communication device (PHY) transmits and receives signal to and from a communication link using a synchronous protocol. The PHY communicates with a higher-layer device using a packet protocol. Timestamp values contained in timing-related messages in some packets are written or modified by the PHY. Delays incurred in transmitting and receiving the packets are predicted and used in setting the timestamp values.
