The No Wire Home Run

Many people have heard of the term "Home Run" for a DSL connection. It is a wire that is run from the point where the phone wire comes to the building and a new wire run directly to the DSL Modem. This is done to not send the High Frequency DSL signal all over the building and through series of DSL Microfilters that have to be on each phone for Voice. The Filter essentially splits the phone line into 2 lines in one wire, the High Frequency, High Speed DSL Data Line and the Low Frequency for Voice. Typically a DSL Kit sent by an ISP will come with 5 DSL Microfilters.

Many times the adding of all these DSL Microfilters and sending the DSL signal through all these Filters makes the DSL signal weaker or even unstable resulting in unexplained drop offs and service calls. In fact my neighbor next door had this very problem. She asked if I ever lose my Internet DSL connection in June of 2003 and I told her it never drops. She is using the DSL Modem that came with her Phone Company ISP kit but I won't comment if it had a weakness or anything like that. Anyway although her DSL Modem does not have a built-in DSL Microfilter I did the "No Wire Home Run" for her eliminating the 5 Filters all over the House into just 1 Filter where the DSL/Phone wire comes to the house box and her DSL connection is solid like mine now.

I am running right now with no extra DSL Filters anywhere in the house other than the DSL Filter that is built in to the Zoom X4 DSL Modem. This is a first to provide a solution for the entire house with no additional filters or wires needed. Of course the Filter Manufacturers won't be too thrilled. It is not good to have a ton of filters anyway, each one adds the equivalent of 700 feet to a line. The High Frequency DSL signal is only good for approximatey 18,000 feet from the ISP origination equipment so if you are say 15,000 feet away and you add 5 DSL Filters around your home (adding the equivalent of 3,500 feet of wire) you just made your signal just about useless.

 

The Zoom X3 and X4 series DSL Modems have a built in DSL Microfilter. You can run a Home run based on the filter, no additional wiring or filters needed. It's super easy.

Here is just the few easy steps to accomplish this:

99% of all homes have a phone cable with at least 4 wires (Most have 6 pairs now) in the cable. The inside pair (green and red, colors may vary) is normally the pair going to all of your inside wiring and jacks.

Go to the box where the Phone/DSL wire comes into your home. If you only have one main phone number to your home then there is only the inside pair of wires to the jacks live. (This is also where you can visually see what color pair is used for your inside phone wires) Simply undo the inside pair and leave that pair un-connected, now simply connect the outside pair and your done with the outside box..

 

At this outside phone box the blue pair goes directly to the DSL Modem in the house. The pair that was feeding the inside phones (in this case orange) is now disconnected. The colors at your house may vary.

 

At the jack where you will have the DSL Modem plugged in you simply either add a double RJ-11 jack if a wall plate or another RJ-11 box type jack. Then you hook the outside pair (This is the pair you made live from the outside box) to the added RJ-11 Jack and label it DSL. Then plug a phone cable to the ADSL Jack on the Modem. Plug a phone cable from the Modem phone jack to the original phone jack on the wall. Almost done. No wires to run, no filters to connect.



Jack labeled DSL is the pair of wires that was connected at the Phone box outside.

That is the "Home Run" that has been created without having to actually run any wire.

The other jack is the original wires running to the phones in the house.

To give voice signal back to all of the phones in the house simply connect the phone wire from the back of the Zoom X4 DSL Modem labeled phone to this plug.

 

To put it in simple terms you are simply moving the point of entry or origination point of the Voice phone signal from the outside phone box to the DSL Modem with the internal built in DSL Filter point. This method can also be done with existing DSL Modems. You would only need one external DSL filter where you have your DSL Modem or you can put the external Filter in the outside phone box to feed the inside phone jacks from there but still having the outside phone pair as a "Home Run" DSL signal to your DSL Modem.
