I just wanted to share my home network. It is not a state of technologies with the latest & greatest wireless or wired network with complex router and switches. I did it in old school way with a single long CAT5 Ethernet Cable. I have a FreeBox which is an ADSL2 router connecting to the main phone jack. The output from the FreeBox connects my PC, Television and Phone. Now all these components are connected with the single wire as I mentioned before. It takes benefit of the fact out of 8 wires in an Ethernet cable only 4 are used for network; the pins 1-2 and 3-6 of RJ45 are used. The connection is simple, wire from pin 1 to pin 1 of the other side and like wise.Similarly, I use the other two pairs for telephone and ADSL.
The input of ADSL router is a simple RJ11 connecting with 2 wires.The connection between PC and router is 4 wires with RJ45 (2 pairs, one pair for transmit and other for receive). The phone needs only one pair RJ11.
These pictures show RJ45 connections in detail and also a picture of backside of freebox.
The success of doing this by oneself depends on one's skill of how good one is with crimp tool as the connections sometimes are not proper and one has to repeat the whole process right from the start. Doing a search for making rj45 cable connections on web will lead to more details. Need any more tips on the same please drop me a line.
