Abstract
A system matches frame counter values between a timing master and one or more slave devices in a synchronous network. To detect synchronization losses, a timing master counts transmitted frames of a continuous data stream. When a synchronization loss occurs, the timing master transmits a message to the slave devices that includes a synchronization frame counter value. The message synchronizes the frame counter value of the timing master to the frame counter value of the slave devices.
