VRING  
The TEA7088A is a Telephone Analog Front End  
device, TAFE, which integrates the three basic  
functionsof a standard telephoneset :  
- Speech network,  
- DTMF generator,  
- Ringer generatoron buzzer.  
A complete telephone set can be designed using  
TEA7088A associated with a low cost microcon-  
troller.
