How come we use cat 5, 6 wire for telephone service and use the standard 22/2 telephone wire as an extension for land lines.


The end of the telephone wire hooks into the router in a standard telephone outlet.


We also hook up the router to the dvr and the blu ray player using an ethernet cable which is cat5,6 as well.


So if we are still transmitting the same signal why do we use an ethernet for the dvr and blu ray and can't hook it up to the outlet for the land line ?


Why are they incompatible? Why not use the same wire and the same endings ?


Is there a good reason for this or is it a conspiracy to keep us confused and make things difficult ?

The telephone service uses a different communication protocol than the protocol used in networking computers on say a home network. Your home network uses the TCP/IP protocol over the Ethernet medium (CAT5e, 6), which allows much faster speeds among other things. These protocol/speed differences require different wiring.


Remember, the telephone service and wiring existed long before we had PCs and networks, etc. The phone company had to find a way to transmit high speed signals over existing voice phone wires. The signal from your dvr to your router is not the same as the signal between the phone company and your router. Also, what you are calling a router is also a modem that is compatible with the phone network. It essentially translates the signal between your home network (dvr, PC, etc.) and the phone network.


In short, the telephone network has different requirements and therefore different equipment/wiring than a computer network.


I know I am over simplifying this but I am trying not to go into the gory details. Maybe someone else has a better explanation.

Yes, that is a better description.

You did fine. I understand now. At least as far as I am able to understand it. I am a rookie , an AV professional . If it was any more technical it would go over my head....



Many thanks.
