Abstract
Apparatus for making legacy network elements transparent to IEEE 1588 Precision Time Protocol operation. Network elements are wrapped by device(s) capable of providing either transparent clock or boundary clock operation. In one embodiment, smart interface converters are used to provide transparent clock or boundary clock operation. The smart interface converters work cooperatively.

Apparatus for establishing IEEE 1588 clock synchronization across a network element between an IEEE 1588 master clock and an IEEE 1588 slave clock, said apparatus comprising first and second cooperating smart interface converters wrapping the network element,
- wherein the first smart interface converter is in communication with the IEEE 1588 master clock, the second smart interface converter is in communication with the IEEE 1588 slave clock, said first and second smart interface converters providing data that allow the slave clock to compensate for delays in the network element.
An apparatus for establishing IEEE 1588 clock synchronization across a network element between an IEEE 1588 master clock and an IEEE 1588 slave clock, said apparatus comprising first and second cooperating smart interface converters wrapping the network element, the first smart interface converter in communication with the IEEE 1588 master clock, the second smart interface converter in communication with the IEEE 1588 slave clock;
- where the first and second smart interface converters cooperate to form an IEEE 1588 transparent clock wrapping the network element.
