You guys rock! I just discovered almost the exact same problem. (I also suspect mice or rain). None of my phones at home are working (no dial tone), and I'm getting a busy signal when I call from my cell phone to my home. My computer DSL is still working GREAT, no problem. So I unplug every phone, and use one phone in one wall jack... not working. hmmm.
- With a splitter I plug my phone into the same jack as the dsl line and get nothing, but the DSL is still working great.
- Ok... I unplug everything out of every jack.
- I go out to the test jack ouside the house and plug in a handset and I get dial tone.
- I Plug a handset into the test jack and call my cell phone and my cell phone rings with my home number. Telco is working.
- I unplug the house from the test jack and call home from my cell phone and I get ringing in my cell phone.
- I Plug back in the house to the test jack and call home from my cell phone again but now I get a busy signal.
. . . .Hmmm. My thinking here is that I must have a short in the residence wiring. If it were an open wire then presumably I would have gotten ringing on both tries rather than a busy signal.
So the DSL must be working with just one wire.
Thanks for the info above. Now all I have to do is locate the shorted wiring. Since it just rained today, might be some bad insulation . ??
