When the telephone cable is used outdoors, it is recommended that users install a
special lightning arrester on the input end of the cable in order to avoid the lightning
effects more efficiently.

Step 1: Connect the end with the ferrite core to a RJ11 port of SIC-FXS/SIC-FXO;
Step 2: Insert the other end to
