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 packaging.

The cable wires for DSL lead from the middle pins 4 and 5 of the plug on the single cable end to the middle pins 4 and 5 of the (gray) DSL plug at the split end of the cable (see fig.).

Note:If you hold an RJ45 plug so that the cable is hanging down and the golden pins are showing upwards and towards you, pin 1 is on the right-hand side, and pin 8 on the left-hand side.

The cable wires for landline telephony (ISDN/analog) lead from pins 1, 2, 3, 6, 7 and 8 of the plug on the single cable end to pins 4, 5, 1, 8, 3 and 6 of the black telephone plug at the split end of the cable (see fig.).
