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 pro-
grammed 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 combination 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.
