You might find configuring the ADSL2 modem to use ADSL1 only improves
reliability and/or performance to the same degree: sometimes the ADSL2 signal
negotiates faster, but has more errors, so a slower connection is, well,
faster in practice.

.....and that probably points to the source of your problems: something is
really messed up in your cabling.  Check your line filters and, failing that,
start to prod your ISP to get the line checked.

You should have no (zero, nil, nada) interference between the voice and data
parts of the ADSL service.  If you do there is something terribly wrong.

(Also, it is not even remotely technically possible to "resync fast enough to
 keep the PPP session up", since the PPP session runs over the emulated
 Ethernet over the ATM connection - and when the ATM connection goes down so do
 all those higher layers.)
