The integrated phone system can be used via an analogue fixed-line network connection, via an ISDN connection or via Internet telephony from VoIP. Besides, the internal ISDN S 0 connection allows you further to use the existing ISDN systems and wirings. Via two USB 2.0 ports the HorstBox can be connected to devices like printers and external hard disks. Then the USB devices that are connected on the HorstBox can be used by all computers from the network.
