A network device may include a timing module and at least one interface. The timing module determines a local time of the network device indicating when the network device sends a synchronization start message. The at least one interface sends the synchronization start message to a time client device to set the current time of day on the time client device, receives a synchronization response message from the time client device indicating that the current time of day of the time client device was set, and sends a synchronization success message to the time client device indicating that the time client device has correctly set its current time of day.

Enhanced pulse assisted time synchronization protocol

A network device may receive first qualification indicators, for a first signal, from all line cards of the network device. The network device may, in response to the first qualification indicators, transmit instructions to all of the line cards to use the first signal. The network device may further receive second qualification indicators, for a second signal, from all of the line cards. In response to the second qualification indicators, the network device may store information for the second signal in order to use the second signal as a backup signal.
