Connecting the Telephony Modem
WARNING
Risk of injury or equipment damage
Connecting the Telephony Modem to the home’s existing telephone
wiring should only be performed by a professional installer. Physical con-
nections to the previous telephone provider must be removed and the
wiring must be checked; there must not be any voltage. Cancellation of
telephone service is not adequate. Failure to do so may result in loss of
service and/or permanent damage to the Telephony Modem.

Connect one end of the coax cable to the cable outlet or splitter, and the
other end to the Telephony Modem’s Cable connector (

nections by hand, then tighten an additional 1/8 turn with a wrench.
Note
: For best performance, use high-quality RG-6 type coax cable and mini-
mize or eliminate splitters between the cable jack and the Telephony Modem.

Insert the plug from the power cord into the Power connector on the Tele-
phony Modem (
