Coaxial cable (coax): This is a round cable with a connector on each end. It is the same

kind of wire used to connect to your television for cable TV. You can buy coax from any
electronics retailer and many discount stores; make sure it has connectors on both ends.
Be sure that the coax cable you choose has screw-on connectors. The coax should be
long enough to reach from your Telephony Modem to the nearest cable outlet.
Note: For best performance, use high-quality RG-6 type coax cable and minimize or
eliminate splitters between the cable jack and the Telephony Modem.
Phone Cable: This is a standard phone cable with standard phone connectors (RJ11 type)

on both ends. You can buy phone cables from any electronics retailer and many discount
stores.
Splitter (optional): provides an extra cable connection by splitting a single outlet into

two. You may need a splitter if you have a TV already connected to the cable outlet that
you want to use. You can buy a splitter from any electronics retailer and most discount
stores; you may also need a short piece of coax cable (with connectors); use it to connect
the splitter to the cable outlet and then connect the Telephony Modem and TV to the
splitter.
Note: A splitter effectively cuts the signal in half and sends each half to its two outputs.
Using several splitters in a line may deteriorate the quality of your television, telephone,
and/or internet connection.
