Note
You can use 1000BASE-T cables for 10BASE-T/100BASE-TX connections.
BGM/MOH
The PBX provides Background Music and Music on Hold. An external music source (e.g., user-supplied radio)
can be connected to the PBX.
CAUTION
The MOH port is an SELV port and should only be connected to an approved SELV device, or in Australia,
via a Line Isolation Unit with a Telecommunications Compliance Label.
Notice
•
Wiring should be done carefully to prevent undue force being exerted on the plug. Otherwise, sound
may only be heard intermittently.
•
When the PBX and external music source are not connected to the same earth, hum noise may be
induced into Background Music and Music on Hold.
Pager
A paging device (user-supplied) can be connected to the PBX.
CAUTION
The Pager port is an SELV port and should only be connected to an approved SELV device, or in Australia,
via a Line Isolation Unit with a 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 SMDR, diagnostics
and external system database storage (save/load) functions.
CAUTION
To protect the system, keep the following in mind:
