Terayon TJ 700x Series DOCSIS Cable Modem Installation Guide

Connecting the Modem

To install your new cable modem, you will need the following items:

Two coaxial cables of a length appropriate to your installation

One cable line splitter

A 7/16 inch (11.1 mm) wrench (spanner).

When installing your new cable modem a cable splitter and two new cables are required. 
The cable splitter divides the incoming signal from the cable company into two signals, 
one for the household TVs, and one for the cable modem. No TV sets are allowed on the 
cable that connects to the cable modem. Figure 2 illustrates a typical cable modem 
installation.
