1. Install a DNI line card in a peripheral card slot.
2. Attach the circuit tip and ring leads to the 25th pair of the DMP.
3. Attach the balanced music source to the 7th pair of the DMP via the
MDF.
To install a DMP for Paging (not supported on the CX/CXi):
1. Install a DNI line card.
2. Attach the circuit tip and ring leads to the 25th pair of the DMP.
3. Attach the paging adapter interface to the 9th pair of the DMP.
4. If required, attach the page control inputs of the paging adapter via the
MDF to the 11th and 12th pair of the DMP.
5. Connect the paging adapter to an appropriate power source
(according to the manufacturer’s instructions).
6. Connect the external speakers as required to the paging adapter via

Tip: To reduce the risk of hum or other interference, you should install the
DMP close to the music source or paging amplifier and keep the cables to
and from the unit as short as possible. If "none" balanced input or output
equipment is used, you may need a balancing transformer (not supplied by
Mitel).
