An apparatus comprising a device at an access node (AN) comprising an interface, a Precision Time Protocol (PTP) engine, and a timestamp module, and a second device at a customer premise node coupled to the AN and comprising a second interface, a second PTP engine, and a second timestamp module, wherein the device at the AN is configured to send a PTP event message to the device at the customer premise node to implement a transparent clock (TC) scheme, wherein the PTP engine is configured to trigger the timestamp module to send a timestamp to the customer premise node when the PTP event message transverses the interface, and wherein the second PTP engine is configured to trigger the second timestamp module to create a second timestamp when the PTP event message transverses the second interface.
