DSL Noise

OK, I installed DSL recently for a customer, and it is creating some bad noise. When the DSL modem is powered and connects, the line becomes very hard to hear on. Here's what I've tried so far:

• Have tried different DSL filters on the phone.
• Have tried phone on different jack. (There are only 2 total in house).
• The jack the DSL modem is connected to is a new run directly to box on outside of house.
• Immediately upon turning power off to modem, noise disappears.
• DSL service works fine, testing out at over 1.3MB.

Should I call the provider ?

Bad modem I would think...never experienced this myself but looking at what you have tried that is about the only thing I can come up with. Either way it's in the handles of the provider now, either by providing a new modem or maybe checking for faulty wiring or defective equipment outside the house.

Had a similar problem at the ISP I work at... ended up that phone system in the house was run using the bargain basement of cheap cable and a monkey. I don't know how it works in your area but around here you get the phone company (Bell) to check everything up to the demark point in the house. Everything past the demark point of the house is your responsibility and they will charge you to look at it. It's probably a good idea to contact the supplier of the DSL and have them enter a trouble ticket with the phone line owner...

**update**

OK,. so as it turns out, the noise was actually due to some interference with their cordless telephone. I did think of this initially, and tried changing channels on both the phone and router as well as completely disabling the wireless on the router. (Verizon provides a 4-port wireless router/modem). Since none of that eliminated my noise (plus the fact that their phone is an old 900MHz and the router operates at 2.4GHz), I figured it couldn't be the phone; but I decided to try a regular handset style phone last night before calling Verizon today and with a standard phone, there is not any noise at all!!!

Looks like it's time for them to get a new phone !

Glad to see it was something simple, for future reference anyone looking in on this topic might benefit from our procedure.

Whenever I get a call from a DSL customer of ours and they say they can't surf the first thing I ask is if the DSL light is flashing on the modem. If not it usually runs into software issues after that (be it the modem firmware or windows). If it is flashing we get the people to remove all the other equipment from the phone line other than the modem (making sure there is no filter on the modem, which is fairly common). If the modem doesn't get sync at this point we instruct them try another wall jack. If the modem does get sync then we tell them to surf for about 15 minutes then add one piece of equipment back (cordless phones are ALWAYS last) and surf for another 15 minutes and repeat the process until the offending part is located. Bell requires us to attempt these steps before opening a trouble ticket with them. For onsite I try to bringin a phone I know that works.
