Abstract
A startup protocol for use in a communication system having a master transceiver at one end of a twisted wire pair and a slave transceiver at the opposite end of the twisted wire pair. Each transceiver has a near-end noise reduction system, far-end noise reduction system, a timing recovery system and at least one equalizer. The protocol includes the step of, during a first phase, maintaining the master in a half-duplex mode during which it transmits a signal but does not receive any signals, maintaining the slave in a half-duplex mode during which it receives the signal from the master but does not transmit any signals, converging The master near-end noise reduction system, adjusting the frequency and phase of the signal received by the slave such that the frequency and phase are synchronized with the frequency and phase of the signal transmitted by the master, and converging the equalizer of the slave. Also included is the step of, during a second phase, maintaining the slave in a half duplex mode during which it transmits a signal but does not receive any signals, maintaining the master in a half duplex mode during which it receives the signal from the slave but does not transmit any signals, freezing the frequency and phase of the slave, converging the slave near-end noise reduction system, adjusting the phase of the signal received by the master such that the phase is synchronized with the phase of the signal transmitted by the slave, and converging the equalizer of the master. Also included is the step of, during a third phase, maintaining the slave in a full-duplex mode such that the slave transmits and receive signals, maintaining the master in a full-duplex mode such that the master transmits and receive signals, and reconverging the master near-end noise reduction system.
