... As can be seen in the application circuit in Figure 9 on page 9, CPC1466 designs require few external components. For the CPC1466, all that is needed is a circuit protector, two resistors and a capacitor. To ensure DSL signal integrity over a wide variety of conditions a POTS splitter type filter is recommended to isolate the DSL traffic from the termination ...

... PR+ and PR- pins. 2.6.2 Over-Voltage Conditions Potentials in excess of 100 V applied to the tip and ring interface will cause the CPC1466 to disable the sealing current hold circuit and enter a standby state with very little current draw. Once the over-voltage condition is removed, the CPC1466 automatically resumes normal operation ...
