The Future of Timing: The Transition to Packet Networks
EEPW
While the "all-IP" world will eventually be a reality, for an extended period of time synchronization will need to support a hybrid of both the older circuit-switched and the newer packet-based timing interconnections. This article discusses the transition of timing and line card synchronization to support hybrid circuit and packet networks, focusing on the board and chassis level and demonstrating how synchronization may be received from the network and how clocks can be routed internally to the system
