DSL Splitter at the Network Interface Box?

[Preston]

Here's my situation.

DSL should arrive here in about a week. I have been doing some reading on DSL and phone lines and what I am thinking about doing is installing a DSL splitter in my network interface box on the side of the house. Then connect the red and green wires to the voice lugs and the unused black and yellow wires to the DSL lugs...then at each phone jack location, install a plate with 2 phone jacks, and wire the red/green to one for voice and the black/yellow to the other for DSL. If I understand it all correctly this would avoid the need for filters on each phone.

The main reason I want to do it this way is that I figure the two black and yellow wires are not being used anyway so why not split it at the box and not filter each phone extention.

Two questions I have are:

1) Does this sound like a good setup?
2) Would this improve the DSL connection by dedicating the two black/yellow wires for the DSL connection?

If you use a splitter, there still has to be a filter on the voice leg.

Perhaps I have a misunderstanding of the splitters...I thought that the splitter acted like a filter (in a way), by allowing the voice freqs to go to the voice lugs, and the dsl freqs to only go to the dsl lugs....

If the splitter is also a filter, yes.

Hi There Again Preston;
You might remember my longwinded post previously but I tried to just have 1 filter at the demark and it worked good for a while, but eventually voice calls became quite staticy and I noticed if I shut down the DSL modem the static went away, so now I have 2 filters stacked at the demark and 1 at each device, so I guess you can not have too many, but try it out as you suggest and see how it works. I think you only really want that dsl line on the black yellow pair directly to just the dsl modem though, there is no good reason to multiple it anywhere else as the only place it is of any good to you is right into the DSL modem. You can not multiplex it or anything like that, you'll need a cable/dsl sharing router to share the connection.

Good point ktkendall, I think I will give it a shot (sending the dsl through the black/yellow to the dsl location)...I'm going to wait and see what SBC sends me though....as you might remember from another thread of mine, my alarm is wired directly to my box on the outside fo the house. SBC said that they have a filter for my alarm that will work in that situation, so we'll see what they send me. Can't wait!
