• The blue and lilac sections are those parts of the installation that use normal telephone cabling
• The green sectors are the Ethernet UTP cabling (Cat 5 and Cat 6) and RJ45 connectors

Electrical Supply Protection

If you also want to include surge, spike, and lightning strike protection then you are best advised to insert them in the following places:

• If you are going to use only 1 such device then it is advisable to insert the Surge Protector between the Telephone Wall Fixture and the Telephone Line Splitter (Double Adapter)
• As this is not always possible you could use 2 of these devices:
  • One between the Telephone Line Splitter and the Micro-Filter
  • The other between the Telephone Line Splitter (Double Adapter) and the Router/ADSL Modem/Bridge/Switch
• Please note that these surge protectors are in addition to those that you have already installed and not to replace them

Note: If you are going to be using USB, IEEE1394 (FireWire), etc. other specialty adapters may be required but the same basic configuration is still applicable. Basically the only section which will change is the Ethernet cabling and RJ45 connectors.

This setup will allow you to share your Internet connection while retaining a fully functional landline telephone service. Multiple computers can be connected to the Internet in this way which will certainly save you considerably on ISP charges for your connection particularly in comparison with a dial-up Internet connection service.

Another benefit is that because you will be using Network Address Translation (NAT) you will have the added bonus of a hardware firewall to add protection against hackers.
