3.7 Connecting to the ISDN Line
Your telephone line is either an analog line or an ISDN
line.
If you have an ISDN line, read here how to connect the
FRITZ!Box with the ISDN line.
Connecting to the ISDN NT
Connecting Set aside the Y-shaped cable (gray-black) delivered in the
package. This cable is a combined DSL/telephone cable.
1. Connect the longer gray end of the cable to the sock-
et on the FRITZ!Box labeled “DSL/TEL”.
2. Insert the black branch of the Y-shaped cable into the
socket of your ISDN NT.
If the plug does not fit into this socket, insert the
plug into the black adapter included in the package.
Then insert the adapter into the appropriate socket
on the ISDN NT.
Now the FRITZ!Box and the ISDN line are connected.
