A timing generator (86, 100) for use in a data communications system is provided. The timing generator (86, 100) includes clock circuitry (106) for generating a local timing signal. Network timing interface circuitry (104) is connected to the clock circuitry (106) and receives a network timing signal. The network timing signal is transmitted to the clock circuitry (106), which outputs the local timing signal. Switch timing output circuitry (114, 132) coupled to the clock circuitry (106) receives the local timing signal and generates a switch timing output signal. |
