Abstract: A frame alignment method and system for communicating frames of information between at least two devices. A `start of alignment sequence` is used to cause a device that is in the misaligned state to inform the other device of this state condition in such a way that the other device itself is caused to transition to the misaligned state. The `start of alignment sequence` is therefore a frame alignment error when a device is in the aligned state. Each device in the misaligned state repetitively transmits the `start of alignment sequence`. Each device in the misaligned state transitions to the realignment state upon detection of the `start of alignment sequence`. When in the realignment state the device transmits the `end of alignment sequence` to cause the other device to transition to the aligned state if the other device is in the realignment state.
