BGM/MOH
The PBX provides Background Music and Music on Hold. Up to 2 external music sources (e.g., user-
supplied radios) can be connected to the PBX.
CAUTION
• Wiring should be done carefully to prevent undue force being exerted on the plug. Otherwise,
sound may only be heard intermittently.
• External Music Jacks are SELV ports and should only be connected to approved SELV devices, or
in Australia, via the Line Isolation Unit with the Telecommunications Compliance Label.
Note
When the PBX and external music sources are not connected to the same earth, hum noise may be
induced into Background Music and Music on Hold.
Pager
Up to 2 paging devices (user-supplied) can be connected to the PBX.
CAUTION
External Paging Jacks are SELV ports and should only be connected to approved SELV devices, or in
Australia, via the Line Isolation Unit with the Telecommunications Compliance Label.
PC/Printer (via RS-232C)
The PBX is equipped with an RS-232C interface. This interface provides communication between the PBX
and the user-supplied devices such as PC or line printers. The RS-232C port is used for system
programming, SMDR, diagnostics and external system database storage (save/load) functions.
CAUTION
Use an RS-232C cross cable (shielded cable) for connection between the PBX and PC.
Make sure to connect both the PBX and the PC to earth.
