Re: Connection drops on Fusion, but is stable with DSL 1

Any suggestions on how to locate a proper splitter after I find that information?

Since there were no POTS splitters that fit my NID I never tried shopping for one of those. My first POTS splitter (I have two lines) was made by Alcatel and came from a professional install back in the early days of DSL. The second POTS splitter I bought myself but it too is a generic model (Siecor, Corning, tii network technologies) with its own outdoor enclosure.

As for the distance to bridge and the difficulty to run new twisted pair cables each home is different. Sometimes a long cable run can turn out to be really easy and another time a short distance can appear insurmountable with difficulties. I was able to drill through the floor boards and run a cable through the crawlspace. Other people find it easier to run a cable through the attic or bring it along the outside of the house to the room of their choice.

If you are lucky you may have twisted pair cable already in your home and can re-purpose one of the pairs (since a phone line and a dsl line only require one pair each). While that may sound much easier then running a new cable, beware that you probably don't know how that existing cable is run throughout the home. Existing phone cables are often installed in the same daisy-chain fashion as electrical outlets. While that is fine for electricity, each splicing/termination at the outlets causes losses in the DSL signal. Also bad are dead ends of twisted pair cable runs (a portion of the DSL signal gets reflected back and interferes with itself). It can be far more work fixing up existing home wiring then installing a new twisted pair cable (it all depends on your specific situation).

I just took another look at your diagram, and I realized that no matter where I plug the splitter in, I will still have to run a wire to my modem, which, given the way my place is built, is quite a bit of trouble.

I'm willing to accept a less than ideal solution. If I can install a filter for the alarm system, I should at least prevent the connection from dropping at ADSL2 speeds, even if I won't be maxing the potential of my line because the DSL signal will be spread around.

How does an ADSL2 filter for an alarm system that has no jacks of any kind look like? Can I buy one on the market?
