The NTE789, a monolithic silicon integrated circuit, is a stereo multiplex decoder intended for FM multiplex systems. This stereo multiplex decoder requires only one low–inductance tuning coil (requires only one adjustment for complete alignment), provides automatic stereo switching, energizes a stereo indicator lamp, and operates from a wide range of voltage supplies........

This project describes an Arduino/MCU interface to a telephone land-line. It's only been tested on a US version of the telephone system, but hopefully it will apply to the phone system in other countries. The basic idea was to allow the MCU to make calls by transmitting DTMF tones, and to receive and decode DTMF tones (keystrokes) made on the phone that was called.There are other possibilities however. Using the complete interface, it should be possible for the MCU to answer calls, and to transm.......
