Making telephone calls with FRITZ!Box through a cable modem

With an additional cable modem, you can also use the FRITZ!Box on a cable connection. If you connect your telephones to the FRITZ!Box, you can use any internet telephony provider that gave you login data for internet telephone numbers. In this case, you can either use internet numbers from your cable provider or from other internet telephony providers. You can also connect the FRITZ!Box to the cable modem if your cable provider allows you use it for telephony.

Note:The configuration procedure and notes on functions given in this guide refer to the latest FRITZ!OS for the FRITZ!Box.

Connecting the FRITZ!Box

  1. Plug the longer end of the DSL/telephone cable ("Y cable") included with delivery into the socket on the FRITZ!Box labeled "DSL".
  2. Plug the black plug on the split end of the cable into a telephone jack on the cable modem.

    Important:When using your FRITZ!Box with a cable modem, you can only use one of the telephone jacks. You can connect a further telephony device, for example a telephone, to the second telephone jack on the cable modem. If the plug on the DSL/telephone cable does not fit into the jack on the cable modem, refer to your cable provider for a suitable adapter.
