| This book describes how you can configure &TCD; to use the |
| telephone network as physical medium for data transmission |
| using computers, so you can create your own collaborative |
| networks to share information with your friends in freedom. |

| To implement the configuration described in this book, you |
| need two or more computers connected to the telephone network |
| of your country by mean of modem devices. Optionally, you |
| could use Ethernet devices (e.g., switches) to create local |
| area networks (LANs) on both ends of each connection |
| established over the telephone network for sharing information |
| between them. For example, consider an infrastructure where |
| you have one LAN for each province in your country and then, |
| each of these LANs is connected one another to share |
| information between them using the country's telephone |
| network. This infrastructure would be as expensive as |
| telephone calls and consume of electrical power required by |
| computers and communication devices would be. |
