3.7.1

EXM/MPPI

The system features a slot for the external music module EXM or the stored music-on-hold
module MPPI. The EXM module is always used in the first option expansion. It is inserted in
the housing cover with the component side facing the cover. The MPPI module is located in a
separate housing with fixed wiring and is positioned in the cable channel of the main distribution
frame.
For the system settings (menu 211), it is possible to choose between music on/off, ring tone or
music when a ringing call is transferred to another user. "Music on" must be programmed when
these modules are connected. Ensure that the orientation of the ribbon cable is correct.
