XN120 Expansion Unit Guide 3
What is the XN120 Expansion Unit
The XN120 expansion unit is connected to the
XN120 main unit to increase the capacity of the
system.
The XN120 main unit must have the
Applications Card (EXIFU-A1) installed before
you can connect an expansion unit.
The system will allow up to 2 expansion units to
be connected to the XN120 main unit.
The expansion unit is supplied with three
exchange lines and eight telephone ports.
The quantity of ports can be increased by
adding optional expansion cards.
The expansion unit does not have the external
music input/external page output socket; this is only on the XN120 main unit. Additional external audio devices
are connected via the 2PGDU cards that can be installed into any unit.
It can also accommodate optional parts to connect ISDN BRI lines.
Separate guides are supplied with the optional equipment.
