ASIC for signal processing and control for public telephones

A circuit that receives and process analog signals from the telephone line is presented; it generates dialing signals, and controls a number of electrical functions (power supply, ...) and mechanical functions (hanging, money-box, ...). This circuit replaces digital and analog electronic components in an existing printed circuit board. One of its main functions is to reduce phone operating power consumption.
