Assignment of the cables and sockets
The FRITZ!Box has various sockets for connecting it to your DSL line and connecting your telephony devices to it. Here you will find the assignment of the cables included with delivery as well as of the FRITZ!Box's sockets so you can use your own cables, for example.
Note:The FRITZ!Box is available in several different product variants, each of which is delivered with different components. For the exact contents of the package, see the information printed on the FRITZ!Box package.
