A system for distributing a synchronization signal in a telecommunications network is provided that includes a timing generator, a lower level distribution module, a bus control module and a plurality of cards. The timing generator is operable to provide a synchronization signal comprising timing and control signals. The lower level distribution module is coupled to the timing generator. The lower level distribution module is operable to receive and distribute the synchronization signal. The bus control module is coupled to the lower level distribution module. The bus control module is operable to receive and distribute the synchronization signal. The plurality of cards are coupled to the bus control module. Each card is operable to receive the synchronization signal and to synchronize based on the timing signals. <IMAGE> |
