telephone line to ethernet adapter?

Question

I am looking fo device which will convert signal from telephone line to ethernet signals which could be handled by networking switch. Also looking for device which will do vice versa.

What am i trying to accomplish:

I have two switches one in my room 2nd in living room, as you expect they are connected with ethernet cable .

phone line is located in my room however i need that phone line in living room for fax.

I am planing to do this

[phone line]<--RJ11-->[phone line to ethernet, device]<--RJ45-->[switch]<--RJ45-->[switch]<--RJ45-->[ethernet to phone line device]<--RJ11-->[FAX}

good luck; run a CAT6 cable and properly terminate both ends w RJ 45 ports and all will work

You do understand that "Telephone lines" have VOLTAGE on them (45 v for ringers) that voltage will be on a telephone line regardless of your "adapters" - if you connect ethernet you will ruin the ethernet adapters in the switches.

You would need to re-wire the telephone jacks to ethernet and be sure they DO NOT connect to ANY telephone line input!

If you want to use the network to carry the telephony traffic you need to convert the telephone part over to what is known as voice over IP (VoIP). It's rather complicated thing to explain in this forum, but you need something called a VoIP gateway (a.k.a. SIP gateway) that will convert the incoming analog voice to VoIP, then you can transport it over Ethernet.

You have an existing just fine Ethernet cable.  Why the Hell do you want to debase your connection by using some "adapter?"   Your "Ethernet cable" is a 4-pair Cat-5 cable.  You can connect two pairs for Ethernet, and use another pair for your telephone service.

Will not work.  First, the switch does data only, it does not replicate the phone signal.
Second, this is pretty dangerous.  I don't see where you are getting your phone input, but a standard analog
phone puts out more voltage than a ethernet network.

In the old days, one could take a pair and punch it down differently (running phone and ethernet on the same cable).  But you would never plug that thing into a ethernet jack without undoing how the pins are assigned.
