Fig.15 Typical application of the UTC TEA1062A ,shown here with a piezoelectric earpiece and DTMF dialling. The
bridge to the left ,the Zener diode and R10 limit the current into the circuit and the voltage across the circuit during line
transients.Pulse dialling or register recall required a different protection arrangement.
The DC line voltage can be set to a higher value by resistor RVA(REG to SLPE).
