xDSL

Add circuit protection in the circuit to help xDSL devices avoid damage from transient surge voltages

Summary Circuit Diagram Documents Others

Summary

Since xDSL equipment is connected to the PSTN infrastructure, it may be exposed to overcurrent and overvoltage hazards caused by AC power crosses, power line induction, and lightning surges. Therefore, effective circuit protection solutions are needed to protect xDSL telecommunication equipment from transient surge voltages resulting from lightning strikes and switching operations.
