All,
Setup: Single phone outlet in the house with a single filter. Cordless phone and Netgear DGN2200 connected.
I have had an unusual experience over the last couple of weeks. On two seperate occasions I have had no dial tone on my exetel phone line (ADSL2 was working on the first of these occurences, it wasn't working on the second). I conducted my own isolation tests and eqipment cycling but no change. I then called Exetel support (on my mobile) who conducted line tests both with and without my equipment connected and they said that the line was "out of specification". On both occasions I arranged for a tech to be sent to investigate. On both occasions I checked the phone immediatly after calling and the dialtone had returned and my modem was able to sync. I then obviously cancelled the tech call out.
The first time I thought it a coincidence, the second I thought "what the ?".
Currently have fully functioning phone and internet so no complaints about the service. Just have no idea why "line testing" (what ever it is that they do) would correct some existing fault on my line. Anyone have any ideas.

Re: Lost dial tone corrected after line testing - Twice
I had a similar experience years ago, when I was with Telstra. Eventually they tracked it down to an issue at the exchange. Apparently a small bit of wire has fallen down on the contacts in the MDF and was intermittently shorting my line. This caused the line to be disconnected by a current limiting protection mechanism. The testing of the line reset this protection and at some time later, it would be triggered again.
