Abstract:
A startup protocol for use in a communications system having a plurality of transceivers, one transceiver acting as a master and another transceiver acting as a slave, each transceiver having a noise reduction system, a timing recovery system and at least one equalizer, said protocol comprising the steps of:executing a first stage during which the timing recovery system and the equalizer of the slave are trained and the noise reduction system of the master is trained;executing a second stage during which the timing recovery system of the master is trained in both frequency and phase, the equalizer of the master is trained and the noise reduction system of the slave is trained; andexecuting a third stage during which the noise reduction system of the master is retrained, the timing recovery system of the master is retrained in phase and the timing recovery system of the slave is retrained in both frequency and phase.
