Program 5485 IP Paging Unit
To program a 5485 IP Paging Unit (this programming procedure provides
a burst of ringing prior to the speech broadcast):
1. Launch the System Administration Tool.
2. In the Multiline IP Sets form
- Program the IP Paging Unit as "5010 IP".
Tip:To reduce the risk of hum or other interference, 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).
Tip:Refer to the 3300 ICP Hardware Technical Reference Manual for
connector pinouts.
Note: See Table 46 for the paging unit pinout and Figure 119 on page
266 for the cross connection wiring.
