Device for synchronization of multiple telephone circuits

摘要

This invention pertains to a method and system for transmitting high speed data from a transmitter to a receiver over several low speed data channels. At the receiver end the differences in the transmission times between data channels are detected and the signals from the faster data channels are delayed to insure that the output high speed data stream is correctly assembled. The differences in the transmission times are monitored during data transmission and if a change is detected the transmission is interrupted and retraining is requested.
