the same wall outlet, you must use a cable line splitter (not included).

the eMTA and connect the other end to an Ethernet port on a wireless router (or other
Ethernet-enabled device).
3. Connect an RJ-11 phone cable (not supplied) to Voice 1 through 4 starting with Voice 1

provisioned through the service provider, telephone service is not available.
4. Connect the power adapter (supplied) to the Power port on the modem. Connect the other
