Dear Authors, et al., 1. The proposed solution recommends the usage of section layer OAM to find signal failures on a link. Since the two nodes will be able to detect failures at either end of a link using the link OAM, why would it be a necessity to send the APS payload to the adjacent node in the direction opposite to the failure? 2. If the switching commands Lockout, Manual Switch and Forced Switch are taken out of the equation, and assuming that a signal failure will be the only reason considered for a switch-over, will it still be necessary to use the APS protocol at all? Thanks and Regards, Naveen T
