Abstract: Systems and methods for implementing bi-directional synchronization propagation between first and second communication devices are provided. The devices are arranged in a loop-timing configuration. A method includes detecting, by the second communication device, a switching signal comprising an indication to switch a timing role of the second communication device and engaging, by the second communication device, in a synchronization handshake with the first communication device over a communication link based on the detection of the switching signal. Engaging in the synchronization handshake includes determining whether the first communication device is configured to support bi-directional synchronization propagation. The method includes switching the timing role of the second communication device based on the synchronization handshake.
