Bizarre Connecting Problem

[dale001]

Using a Verizon 7500 modem with a direct line coming in (“dedicated line”) to my  system (with homerun filter).

I keep getting disconnected from the Internet and here’s what’s happening:

The Internet light will turn red OR my DSL light will blink (either way, I’m disconnected).

Then I will use a phone in the other room (a phone that is NOT on the same line) and often, before I finish dialing ANY number, my modem will correct itself and I’m back online. It doesn’t matter whether I dial Verizon tech support or any phone number, and my service returns; often, all I have to do is begin dialing, and before I can finish dialing, the modem re-connects. Bizarre.

Keep in mind, my phone uses a separate line into the house.

Clearly there is some kind of interference, but Verizon told me I wouldn’t need a line filter for my dedicated/direct line. And why it loses signal in the first place is also a mystery.

Any ideas--and YES--this has happened frequently enough for me to say that it is NOT a coincidence that the connection becomes restored by such actions (as simply dialing on a nearby phone).

Bizarre . . .

P.S. I should also add that this is a relatively new issue: began a few weeks ago--and nothing "new" has been added to the home during that period that would affect this unsual happening.

Why do you have a dedicated line?  Did VZ recommend this?  The whole idea behind DSL is that the home network can share a phone line with plain old telephone service. 

What is a homerun filter?  The only filter I'm aware of is the set of 4 filters that come with the set up kit that  VZ sends out for new DSL customers.  You should NOT have one of those filters in the line ahead of your DSL modem.  Have you tried the whole setup without the homerun filter? 

Does VZ know about your bizarre symptoms?  This kind of cross interference between phone lines ought to be extremely rare, and is almost certainly a phone company problem.
