Abstract: A circuit and method for synchronizing a service clock at a destination node with a service clock at a source node for circuit emulation service over a packet network. The method includes receiving data packets from a source node at at least one port of the destination node. At the destination node, the method removes from the data packets residual time stamp (RTS) values that were created at the source node based on at least the service clock at the source node. RTS values are stored in memory at the destination node. The method determines a majority count and a minority count of RTS values over a period of time from the RTS values stored in memory. The method further uses the majority and minority counts to set the frequency of a service clock at the destination node for use in receiving data packets.
