I have a Billion 8800NL R2 which worked fine but does clock up quite a lot of FECs, (non-critical on my line), and the SNRM varied noticeably but not dramatically.
It sync'ed at roughly the same speed as my AAISP-supplied VMG1312-B10A, which was a bit buggy as WG says. I flashed with the latest firmware from ZyXel, not from AAISP, and ran it in bridge mode into my ASUS RT-N66U. for many months, maybe a year. I didn't encounter any bugs.
FECs were hugely lowered compared to the Billion, down from 10s of thousands per 5 seconds on MyDSLStats normally below a hundred, and SNRM varying by steps of 0.5dB over a range of 1,5-2.0dB over 24 hours.
I've only stopped using it in that configuration because I have now ditched FTTC completely and am now tethering my mobile to my system
either via the ASUS powered USB or as a wifi hotspot or USB into my laptop. Depending on needs.
The only real difficulty with setting up the ZyXel is that the instructions for bridging are very garbled. In fact IIRC written for it to be bridged into, not being the bridging unit. Even the DSL setup, which is closely connected, is a nightmare at first.
If you happen to go that way I can soon power it up and try to send some screen shots of it as when I was using it.
Banger also uses the same ZyXel with the same firmware as myself, bridging to whatever his router is.
Edit: I was able to turn off TR-069, but whether or not you can on the other (later) models, which others say you can't, I don't know.

If you never think of anything off the wall, you'll never think of anything original.
