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

You can connect your FRITZ!Box with a DSL line and an additional phone line (analog or ISDN). If you have a DSL line without an additional phone line, proceed as described in the guide Connecting the FRITZ!Box with the DSL line.

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, which are delivered with suitable 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 phones and telephony devices to the FRITZ!Box

  2. Connect only the DSL splitter to the first phone 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 phone jack.
