Warning - this model AVM is partion for standard Annex B - which is used only in Germany (because of numeris network). This model will therefore not work in the rest of Europe - or Annex A standard is used (France, Switzerland, Austria, Spain, etc). Also be sure that apart from the Annex A to that standard (encapsulation) DSL-ATM used by your ISP is compatible with the Fritzbox. (Fritzbox done for now PPPoE PPPoA / VCMUX and PPPoA / LLC, for against PPPoE / VCMUX is not mastered - eg required in non-unbundled areas for Free.
Otherwise - a very successful solution because of these functions we do not discover in the box of french ISP.
