Selecting an Installation Location
There are a number of factors to consider when choosing a location to install your Telephony
Modem:
Is an AC outlet available nearby? For best results, the outlet should not be switched and
should be close enough to the Telephony Modem that extension cords are not required.
Is a cable jack available? For best performance, keep the number of splitters between the
jack and cable drop to a minimum. Each splitter attenuates (reduces) the signal available
to the Telephony Modem. A large number of splitters can slow down the Internet
connection and even affect your telephone service.
Can you easily run cables between the Telephony Modem’s location and the phones?
