<p>A method for data transferring between exchanger and terminal transferring data between exchanger and terminal using bi-directional FSK mode. The FSK signal modulation mode is consecutive phase binary Frequency Shift Keying(FSK), data transferring mode is binary asynchronous serial mode, and sequentially FSK data is transferred according to byte. Also, present invention provides a FSK process module, a terminal and a exchanger. The invention hugely improves the information transferring rate between exchanger and terminal by transferring data between exchanger and terminal using bi-directional FSK mode, and it provides the support on communication layer for developing large mass of data interactive service between exchanger and terminal.</p> |
