Actually no...

What I did find is that if I stop polling the modem to see what its
external IP was (by telnetting to it with an expect script), then DSL
stays up much much longer than if I poll it every 2 minutes.

Perhaps there's some sort of memory leak ... but I found that it would
reboot (red light flashing etc) quite regularly if I left the script
running. Stopped it, and it was a lot happier.

And since telecom adjusted the error tolerances on everything, I (and
everyone else) get the same IP address 9 times out of 10 when dsl does
drop, and that's not all that often.

3 filters on 2 phones and the decoder, I believe
