Power can be supplied either locally or via Power over Ethernet (PoE) in accordance with the IEEE 802.3af standard. Open hardware and software platforms enable future capabilities and features such as the SIP VoIP protocol.

In addition, this model enables the connection of other IP devices, like PC, printer and phones via the integrated 10/100 Base-T mini-switch. With only one LAN cable you can save network resources (one wire to the desk). A connection for earpieces and headsets is also provided, making this the ideal product for workstations subject to a high volume of telephone.
