Default line gain up or down



From what I understand line gain too high can effect a negative adsl line
test. I have been on to BT who have said my line gain is set to the default
of 4. They are willing to set the line gain to zero, but I wanted to check
first whether this is the best course of action to reduce the line gain, or
to leave it at its default setting?
thankyou

sounds like an urban myth. The gain will be on the input stage of an
exchange line card for audio frequencies, whereas the line test will
be on the line at 300 kHz ie way above audio frequencies.

The information I received about the line gain is from www.btofaq.net who
are quite up to date with their information. Maybe its not true, but if it
is its worth a try?

The only thing it may (repeat may) affect is your Signal to Noise Ratio.
Personally I wouldn't bother, but each to their own....

Is this signal to noise ratio an integral part of the adsl line test?

Then it might be worth getting it lowered for a week while they do the
tests. I have nowt to lose :-)

Too late...
Our last communication about your broadband order let you know that we were
remote-testing your phone line to check that you could receive broadband.

We're really sorry to have to tell you that the tests we've carried out show
that your telephone line is currently unable to support broadband.

We understand how disappointed you must feel. In this email we suggest
possible alternatives - please call us if you'd like to discuss these
further.
