Caution:
z You should connect a cable to the port with the correct mark. Misplugging is prone to impair the
SIC/MIM and even damage the router.
z 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.
z One end of the telephone cable has a ferrite core. To ensure the compatibility of the Router, users
should connect the end with the ferrite core to the Router.
If the SIC is properly installed, follow these steps to connect the cable:
Step 1: Connect the end with the ferrite core to a RJ11 port of FXS/FXO SIC ;
Step 2: Insert the other end to
z a telephone or fax or the AT0 loop trunk if a Router 1 or 2-Port FXS SIC is
installed;
z a subscriber line of exchange if a Router 1 or 2-Port FXO SIC is installed;
Step 3: Power on the Router, and check the LEDs of the corresponding slot on the
front panel: ON means that the SIC is operating normally and OFF means that the
POST of the SIC has failed. In the latter case, please contact your agent.
