At some point during my tests I got a second device (an Arcadyan VGV7510KW22 - which came as "Annex B" device from the factory). Using the very same config made this device sync fine.

Indeed, I have read multiple times that the DSL modem should support all annexes - but as our tests have shown: it doesn't (at least for ADSL). My guess is that the modem physically supports it but there's a bootstrap pin (to which a resistor is soldered... or not) which configures it to be Annex A *or* B only. The interesting part: VDSL is not affected by this (all ISPs in all countries seem to use VDSL over ISDN). I am using an Annex A device on a German VDSL line and this is working fine. bottom line: it seems that the modems are bound to a specific annex for ADSL operation.
