Hack your House: Run both ethernet and phone over existing Cat-5 cable

Step 11 Test

Plug the RJ-45 plug into a router or switch, and your computer into the RJ-45 jack. Test this connection.

Plug the RJ-11 plug (the one on ex-telephone cord) into the phone junction panel.

Plug a phone into the RJ-11 jack. Listen for a dial tone.

You might not know that you can plug RJ11 plugs into RJ45 sockets, it's specifically designed like this. So your 2nd socket could be an RJ45, this could be a bonus depending on how easy it is for you to find RJ11 sockets.

Only downside to this is someone trying to plug a computer etc into it.

Ideally should have double cable runs to every panel in a house anyway, and then patch as you need. It's nice to see some places are being cabled like this now - but then seeing single runs makes me die inside ;)
