Abstract
A network interface for recovering timing information over packet networks has line card at the edge of a local network and a timing card separate from the line card. A physical interface time-stamps incoming timing packets based on smoothed recovered clock signals. A clock recovery module on the line card generates timing signals from the time-stamped incoming timing packets. A first phase locked generates raw clock signals from the timing signals. A second phase locked loop on the timing card generates the smoothed clock signals from said raw clock signals and applies them to the clock recovery module on the line card.
