Pin assignment of ports for telephony devices

The FRITZ!Box has various ports for connecting telephony devices. Here you will find the pin assignment of the FRITZ!Box ports so you can use your own cables, for example.

1 RJ11 sockets of extensions "FON 1" and "FON 2"

The RJ11 sockets "FON 1" and "FON 2" only use the two middle pins.

2 TAE sockets of extensions "FON 1" and "FON 2"

The TAE sockets "FON 1" and "FON 2" are assigned so that contacts 1 and 2 of TAE plugs from telephony devices must be assigned (see fig.).
