Connecting to the ISDN Line
1. Connect the longer of the two gray branches of the ca-
ble to the port labeled “DSL/TEL”.
2. Then connect the other end of the cable to the corre-
sponding socket on the DSL/VDSL splitter. If the end
of the cable does not fit into the socket on the splitter,
insert the end of the cable into the gray RJ45/RJ11
adapter included in the package and then insert the
adapter into the socket on the DSL/VDSL splitter.
The green “Power” LED stops flashing after a short
time and remains lit to signalize that FRITZ!Box is
ready for Internet connections over DSL or VDSL.
