Connecting the FRITZ!Box with the DSL and telephone line (analog / ISDN)

You can connect your FRITZ!Box with a DSL line and a telephone line (analog or ISDN).

In this guide we show you how to connect the FRITZ!Box in Germany, Austria or Switzerland, and how to set the country of use and DSL standard in the FRITZ!Box.

Not all of the cables and adapters mentioned in this guide are included with every FRITZ!Box. If you are missing cables or adapters, you can either purchase them from an electronics retailer, or you can make your own using the guide Assignment of cables, adapters, and sockets.

Note:Our sales team can provide you with information on country-specific FRITZ!Box models that are delivered with the necessary cables and adapters.

Prerequisites

  • The DSL line must comply with a DSL standard supported by the FRITZ!Box.

Note:All instructions on configuration and settings given in this guide refer to the latest FRITZ!OS for the FRITZ!Box.

1 Connecting the FRITZ!Box to the DSL line in Germany

Connecting all telephones and telephony devices to the FRITZ!Box

  1. Remove all telephony devices, cables, and additional telephone jacks from the first (main) telephone jack in your home.

    Important:Disruptions on the DSL and telephone connection can occur if cables or devices other than the DSL splitter are connected to the first telephone jack.

  2. Connect only the DSL splitter to the first telephone jack that you received from your DSL provider: Insert the cable into the "Amt" socket on the DSL splitter and the other end in the "F" socket on the telephone jack.
