With your own router and a properly adjusted timeout it will survive both a full modem reboot just fine. Never seen the DSLAM reboot so can't comment there...
Whether they are designed to or not, they do hang on, others have witnessed the same. SRA is used and is what makes the on the fly resyncs so fast meaning the router can hang on. You can always tell a SRA event from a full reboot because the stats aren't reset and more often than not the PPPoE session is maintained, as a result the IPProfile doesn't update.

In the early days BT Retail used to force a resync in the early hours every day. All CPs can automate this, it's detailed in the SIN's, they stopped doing that though, I suppose too many people were complaining it didn't stay connected for more than a day.

I agree a long enough timout will survive a full modem reboot.
