Connecting the Xn120 System Phones
The Xn120 system phones can be connected to any of the eight RJ11 telephone
sockets labelled ST1 to ST8 in the Xn120 unit.
The Xn120 is supplied with RJ11 to bare wire cables for connection to optional
distribution frames.

Check Power Fail Operation later in this guide, ST8 can be used to provide a
working telephone should the power be disconnected from the Xn120.
Use the line cord supplied with
the system telephone.
The line cord supplied with the Xn120 system telephones can be
plugged directly into the RJ11 sockets labelled ST1 to ST8 in the
Xn120 unit.

telephone cable back to the distribution frame. Connect to one of the
sockets labelled ST1 to ST8 using one of the RJ11 to bared wire
cables supplied.
