Effect of reversing bt line connections on ADSL snr

My BT line was adsl enabled 18 months ago and I have had ongoing
problems with connecting to the service - typically when the SNR drops
<3db as reported by either my adsl router or voyager modem, depending
on which is connected. I gave up with the AOL / BT / Indian call centre
run-around a while back but that is another story.

In the course of experimenting with the connections at the BT socket I
have found that when the modem "drops out" I can restore the connection
by reversing the twin incoming bt wires. At the moment these are
connected directly to an in-line adsl filter, but I am considering
fitting a dpdt switch when I reassemble everything with a new master
socket.
I wonder if anyone can explain this?

can you do the same by just rebooting the modem ? I am wondering if
the disconenction part of the reversal is the key.

I have tried both rebooting the modem and disconnecting/reconnecting
the bt wires from the filter and this very rarely makes a difference.
