Just one connector, but need to connect ethernet and phone?

Question

I have just one RJ45 jack. I need to run an Ethernet and Phone connection thru this. Is there a multiplexer or other device that can let these coexist in 1 channel and then split it on the outside ?

Its not a DSL modem. I have Cable TV/Internet....

Answer 1

It's called a filter. It plugs into the phone jack and splits the phone and DSL lines (frequencies).

Answer 2

With DSL you will be given filters that are to be put on each telephone line. At least one of those filters will have both a connection for the DSL connection and one for your phone.

The DSL modem changes your Ethernet into signals that use the frequencies of 20,000 Hertz and above.

DSL works because the human can only hear up to about 20,000 Hertz. So what they do is put filters on your normal phone line that block anything above 20,000 Hertz. Then on the line that is connected to the DSL modem they do the opposite and block from 0 - 20,000 Hertz, leaving all the frequencies above available to the DSL signal.

P.S. there is no way to directly connect an Ethernet (RJ45) line to your telephone. They are completely different things (Ethernet and telephone) even though the Ethernet connector looks like just a big telephone connector.

P.S.S. Even if you bought a DSL modem and filters on your own and connected it to your telephone line it would do no good. You need equipment on the telephone company/ISP side to convert the DSL back into Ethernet and out to the Internet, which is what you pay for when you get a DSL connection from your ISP.

Just pick up a cheap modem and install or just ask some friends if they need their old modems... I am sure you will end up with more than one...

But RJ45 and RJ11 adapters... I doubt you will find one... couldn't see any average uses for those... good luck...

Answer 4

No, because each operates on a different voltage. I don't remember which voltage goes to which anymore, but you'd end up frying soemthing.
