1 ON/OFF SWITCH (Provided only on products that carry the CE mark)—
Allows you to turn off of the cable modem without removing the power cord.
Turning the cable modem off using this switch ensures that the unit is
consuming no energy.

to conventional telephones or fax machines. (Products shipping in North
America support lines 1 and 2 on port 1 when used with a two-line phone.)

or your home network

instructed to do so by your service provider. Doing so may cause you to lose
any settings you have selected.
