The number of key extensions connected to a system telephone (up to three) can
be set in the Configurator of the OpenCom 100's Web Console (in the menu
Telephony: Ports: Upn or Telephony: Devices: VoIP Phones). Here the keys can
also be programmed as call keys or assigned functions or destination call
numbers. Users can change this programming as required. The maximum distance
between the connecting socket that the telephone/key extension device combi-
nation is operating through and the OpenCom 100 must be less than 1000
metres. You will need a plug-in power supply unit no. 4516000 (in Britain operate
only the AC adapter with the part no. 4516001) to provide power. The power
supply unit is plugged into the last in the series of key extensions.
