... Cordless telephones Answering machines Fax machines Hands-free car kits. GENERAL DESCRIPTION The TEA1095 is a bipolar circuit, that in conjunction with a member of the TEA106X, TEA111X families of transmission or TEA1096 transmission/listening-in circuits offers a hands-free function. It incorporates a transmit amplifier, a receiver channel amplifier and a duplex controller with signal and noise monitors on both channels. ...

... This would cause the TEA1095 to go into the idle mode and the user of the set would hear the dial tone fade away. To prevent this, a dial tone detector is incorporated which, in standard application, does not consider the input signals at RXIN as noise when they have a level greater than 42 mV (RMS) ...
