clock synchronization system and method for advanced telecommunications computing architecture

摘要

clock synchronization system and method for advanced telecommunications computing architecture the present invention provides a clock synchronization system and a method for an advanced telecommunications computing facility. the system is located in a mainframe register that includes a node plate (5) and a backboard, and the system comprises a clock subcard (1}, a rear clock insert module (14), and one for receiving and process the external clock reference, select a reference clock, and then process it in three types of clocks, distribute them respectively to three clock buses on the backboard, produce a synchronous cascade clock and send it to the rear clock slot (14) via the small backboard module in the middle layer; the small backboard module in the middle layer is used to interconnect access interfaces for clock reference of each clock subcard and interconnect output interfaces from cascade clocks.The present invention saves clock resources and reduces costs, while at the same time reducing complexity and increasing system reliability, as the system only r it includes a rear clock insert card and a cable to produce synchronous cascade clocks.
