The PSTN line voltage is usually about 50V (can obviously vary a bit)
but, from my experience, can vary quite a lot on a cable line.
On the 'INFO' tab, under PSTN, it shows the line voltage. I assume
that is where you are checking. The voltage shown shouldn't fluctuate
as you refresh the page.
Just yesterday I was setting up a 3102 for a friend on a Telewest area
line. Amongst other problems I found that the line voltage, indicated
by the web interface, was showing low and was fluctuating on page
refresh. I replaced the lead and there were no further problems. A
connecting lead, normally attached to a phone, is not suitable for
conecting the PSTN line to the ATA. We did find, however, that a modem
lead worked well. All I am suggesting here is that you change the lead
from the PSTN to the ATA, it could be something as simple as that
which is causing the problem for you.

Thanks for your comments. I'm pleased to have been of help.
