Annex B only !!!

I bought this Modem Router, planning to use it with at ADSL2 + connection in Belgium, whichwill be soon migrated to a VDSL connection, and it did not work. The reason is: it's at annex B modem, Which Means it works with IDSN lines only, and, of course, in Belgium, most lines (and so is mine) are PSTN ... So, if you plan to buy this modem for Another Country than Germany, be careful.
Otherwise, the router functions worked perfectly and Seemed really good (for what I've tested), this is why I give 4 stars.
I sent it back to Amazon and had a complete refund, Which would not havebeen not possible with someother sellers.
