More on DSL in Luxembourg

In my quest to get reasonable home connectivity in Luxembourg, I played with the idea of re-using the modem/router/wi-fi combo device I had been using in Germany. (A Draytek Vigor 2500We, with "Annex B" printed on the back side in large, friendly letters.)

Not so: Turns out that Deutsche Telekom's UR2 standard for DSL connectivity means ITU-T G.992.1 annex B everywhere (even on analogous lines), while Luxembourg P&T is using G.992.1 annex A for POTS, and annex B for ISDN. The local computer store goes even further and warns to only use Zyxel DSL modems in the Grand-Duchy -- everything else, they say, inevitably comes back because it won't interoperate.

Interesting times ahead before Internet access will actually work here...

I have a D-Link DSL564T running in Lu, in the manual it says it is "ITU G.992.2 (G.lite “Splitterless ADSL”) compliant", but we USE a splitter. It will be replaced by a Draytek 2600 because of the VPN functionality. This is also an Annex B model. It will be used with an ISDN line. Are you sure that this will not work? Thank you Benjamin
According to P&T's spec, DSL over ISDN is Annex B here, so that could work. At home, we're now waiting for DSL over POTS to be activated, and that's where the Vigor 2500 won't be useful.
Benjamin:
Could you please give me the url of the specs? Thank you Benjamin
All I have is a fax P&T sent me when I asked their hotline about compatibility of DSL modems.
