摘要： A method and apparatus for automatically establishing a data connection includes a telephone line interface circuit coupled to a subscriber telephone line, and a modulator and demodulator circuit coupled to the telephone line interface circuit. A control circuit is coupled to the modulator and demodulator circuit and conditions the modulator and demodulator circuit to establish a connection to the subscriber telephone line and comprises circuitry to determine whether a central office to which the subscriber telephone line is connected is a tone-dial central office or a pulse-dial-only central office, whether a dialing prefix is necessary to access the subscriber telephone line, and whether the call waiting feature is activated on the subscriber telephone line.

摘要： A telephone system for transmitting either a dial pulse signal or a dual-tone multifrequency signal along a telephone line. This telephone system includes a switching means for changing between a KEY signal from a key board and a control signal from a CPU. When a power interruption sensing means senses that the external power voltage is below a predetermined voltage, the switching means shunts from the control signal to the KEY signal and transmits either the DTMF signal or the DP signal along the telephone line.
