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…
