Need DSL Help

[Wormo]

I currently have Directv DSL as my provider. They want to charge me $150 to run a dedicated line to my NID outside, I told them forget it. What I did was ran a 50ft phone cord from my DSL modem to the NID. The first thing I did was disconnect the inside phone system from the NID and use that jack to go straight to my modem. I tested my speeds on dslreports.com and they doubled. I reconnected the inside phones back to the NID and use the extra terminals for my new line. Since I did this with regular phone cord and not Cat-5 I decided to use that cord for the line. So next I cut off one of the jacks and connected the red and green wire to the proper NID terminals. I ran a final test only to discover that my speeds decrease back to the original rate when I used the inside wiring for my connection. How is this possible?

Phone cords are not twisted pair and most of them are braided wore not solid copper. You could do the same thing (if you mind the slopiness) with reg CAT 3 wire just use the Blue/White w/ Blue Pair (Blue goes to Red, and White w/ Blue to Green. and attach the one end to the NID and the other to a jack.

Instead of useing the Phone Co., you can hire a vendor, any compentant electrician can do it. Also you dont need CAT 5 as CAT 3 is more than enough for DSL.

The bottom line is that DSL uses High frequencys above that which are friendly to standard house telephone wiring. You will want to split the signal at some point, usually done at the NID, and feed the house phones their proper signal having the DSL filtered out.

Having the high frequency signal that DSL uses on the house phone wiring is bad for two reasons. It degrades the DSL signal, and it makes static on the phones.

If you have a splitterless install and want to convert it, the SPSH70SR1 ADSL POTS Splitter w/Enclosure found at this website will do what you want:

I have one of these installed at work, and it solved the problem. It's a pitty the phone company is too cheap to install these, as this is the best way to have DSL installed. They save themselves from buying, and installing the box by having you buy and install filters on all the phones. But filters are not the best solution, a splitter is.

Pinkey is correct a splitter is the best way. A filter adds about 900' of resistence to the circuit. While 900 might seem alot for some people at the end of the loop this can cause problems. But there are ways to use just 1 filter in the Network Interface (NID, SNI, CAC) but this is usually done by the phone Co since they have the extra parts for the NI.
