Title: method for controlling a handshaking of xDSL system
Inventor: KIM SANG UK
IPC: H04L12/28
Filed: 2001-12-27
Abstract: PURPOSE: A method for controlling handshaking of an xDSL system is provided to variably transmit an echo signal transceived through an EOC(Embedded Operation Channel) of a frame, thereby considerably reducing load of the xDSL system. CONSTITUTION: An xDSL system is drive by a default setting value(S2) in an initial state(S1). The system transmits a testing signal of checking whether a current transmission path state is good(S3), and decides whether the transmission path state is good(S4). If so, the system transmits a message signal for handshaking with variable transmission frequency(S6), and sets an optimal transmission speed and continuously checks the transmission path state(S7). The system decides whether characteristics of a current transmission path are frequently changed(S8). If not, the system makes a transmission period of an information collecting message signal shorter than a preset general period, and collects transmission path environmental information(S10). The system determines an optimal transmission method(S11).
