Yes you can but depending on the length of the cable, you may not be able to have a connection speed of more than 100 mbps because of the 48V phone line running along the Ethernet link. You have to understand that this is completely outside the structured networks guidelines... but it may be quite useful if you have a lack of cables. So, do that only if you really cannot add another wire without having to destroy you walls or ceilings.

Use the blue and brown pairs for the phone and green and orange pairs for the Internet. Be sure to untwist the pairs as close as possible to the connect point. For that kind of setup, I recommend you to use a BIXed wall plate such as the Belden AX100344 (2 ports) or AX100352 (4 ports).

For the Ethernet outlet, the orange and green wires would go exactly where they should: 3,4,5 and 6.

If you are using a 2 ports plate (AX100344), the blue wires will go into 1,2 and the brown will go into 3,4 of the second outlet. This will make your phone outlet carry the 2 phones lines. Some business phones actually support receiving the two phone lines like this.

If you are using a 4 ports plate (AX100352), exactly as with the 2-port plate, the blue wires will go into 1,2 of the second outlet. Then, the brown wires will go into 3,4 of the third outlet. This way, the second and third outlets will have regular phone lines in which you will be able to plug any kind of domestic phone. Unfortunately, the forth port will remain unused.

This being said, I have explained only how to connect the wall side since I don't know anything about where and how the other end is terminated.

You need the blue with the white stripe and the white wire with the blue stripe.This would be line one for a phone. but if the RJ45 is in use for an Ethernet connection I would not do it, I would just run a new cat 3 wire for the RJ11.

you plug one end in "tester" and other end in "remote" and if it's all good and you are testing straight-through cable it should go from 1 to 8 in sequence. short cable is test (good cable) to show you if there is a problem with your unit. Whatever you see with short cable you should see with your cable.

I have a (like) phone chord and can't find where to put the other end. We have it plugged into the back of the router, need to know where to plug the other end.


Hi

It depends on which country you are in.

It depends what Broadband wiring setup you have.

It depends which type of cable you are talking about (see images 1 and 2 below)

In some countries, the RJ11 to RJ11 cable goes from this device into the phone Socket of an ADSL filter. One RJ45 to RJ45 cable goes from the Router into the Ethernet Socket of the ADSL Filter. Another RJ45 to RJ45 cable goes from the Router to the Computer. The ADSL Filter then goes into the Phone socket in the wall.

You need an ADSL Filter in every Phone Socket that has a telecommunications device attached to it (Fax Machines, Answering Machines, TV Set Top Boxes, games Consoles etc.). The ADSL filter separates Telehone, Voice & Fax Data traffic from Broadband traffic and allows all to share the same phone line with out conflict.

See Network Diagram below.

In some countiries or wiring setups, the RJ45 to RJ45 cable form the Router to the Wall does not need to go via the Phone Socket and can go directly into its own dedicated Ethernet Wall Socket.

How do you wire a RJ11 phone jack with cat6 wire??


I assume you are using this configuration to connect a phone and not data outlet.
The RJ11 connector is used for phones and the RJ45 is used for data.
The CAT6 cable has 8 wires and to wire this cable to a RJ45 connector 2 wires on the CAT6 cable are not connected.

Go to this site for a wiring diagram for RJ11 to RJ45.

I want to connect a CAT5e Ethernet cable (with or without a RJ45 connector) from a DSL router to an older computer that only has a RJ11 input. This will be used for DSL internet service only -- no...


The only "outputs" from a DSL-router are:
* RJ-11 telephone-jack, only if the router also supports voice-over-IP,
* RJ-45 Ethernet port (always present)

You need to purchase an internal network-card, to create an RJ-45 port on the computer, and then use the CAT-5e cable to make the connection.

http://www.ertyu.org/steven_nikkel/ethernetcables.html

this link covers proper pinout for cat 5 cabling. (RJ45). A phone line is RJ11. You can run ethernet cable through a wall and terminate it at a wall plate designed for ethernet (not a standard phone wall plate). You can't use the RJ11 cable currently in the walls for ethernet.
