  • Page 17: Theory Of Operation

    Appendix B. Theory of Operation B.1 Theory of Operation The COM300 modem is used to transmit data over bandwidth-limited channels such as telephone lines by modulating audio tones, using Phase Shift Keying (PSK) at 9600 or 1200 baud and Frequency Shift Keying (FSK) at 300 baud. The telephone company gives a 40 to 150 VRMS, 20 Hz signal on the telephone lines to signify a ring, which is typically on for 2 seconds and off for 4 seconds.
