Not exactly. There is one cable that goes from the outside Xfinity (Comcast) box to the panel box in the garage. Then, there are about 6 or 7 cables that run from the panel box to each room outlet throughout the house. When you sign up for Xfinity service, Xfinity will usually only activate the room outlets that you want and connect them to a splitter inside the garage panel box. You can only use the activated outlets with an Xfinity cable box or modem or an approved modem that you own. Xfinity can control your service remotely because the cable boxes and modems can be monitored, activated, or deactivated remotely. Also, the cable boxes are encrypted to prevent you from stealing the service. You can move a cable box or modem from an activated outlet to an unactivated outlet, but you would need to disconnect one cable from the panel box splitter and connect the unactivated cable, so you would still have the same number of activated outlets. You could do this yourself. But, if you want to increase the total number of activated outlets in your house, you would need to rent another cable box from Xfinity, and they may need to come to your house to replace the splitter, and to possibly increase the power of the signal entering your house. That is how I understand the system works in most houses.
