Mainly introduced one kind of 200 card generation dials, the realization user picks the machine-hour to dial 200 automatically (turning on number) and 3 (service number), account number, password; The system take the monolithic computer as a core, its main hardware module by microprocessor AT89C2051, EEPROM24C02, double sound multi-frequency transceiver MT8880 and so on is composed. The main function is the generation dials 200 card numbers and prevented the telephone is abused.The user may carry on the establishment through the local telephone to this product.This installment is extremely exquisite, the electric circuit is simple, the cost is inexpensive, the operation is simple, the expansion function is formidable; May the widespread application on the home use telephone or other fixed telephones, enables the people to use the direct dialing to be such convenient likely. Key words：The generation dials, the double sound multi-frequencies, the I2C main line serial port memory, the double sound multi-frequencies arrange the decoding Abstract At present the widespread use IP pre-payment card brings materially beneficial at the same time to the people, also has brought the trouble.
