Pager
Up to 2 paging devices (user-supplied) can be connected to the Hybrid IP-PBX.
CAUTION
External Paging Jacks are SELV ports and should only be connected to approved SELV devices.
PC/Printer (via RS-232C)
The Hybrid IP-PBX is equipped with an RS-232C interface. This interface provides communication between
the Hybrid IP-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.
When using special accessories such as cable, the user should use those specified in this installation
