Chapter 12: Configuring the ISDN and analog interfaces in detail
With the internal power supply, the models LANCOM 1723 VoIP and
LANCOM 1823 VoIP support a maximum of two telephones without their
own supply; power is fed from the ISDN2 interface º.
To activate the internal power supply, the corresponding DIP switches (1
and 2) must be up; to deactivate, the DIP switches must be down.
The power supply switches off automatically in case of overload, and
switches on again once the load drops.
Before altering the DIP switch settings, remove all cables from their sock-
ets.
Remove the see-through cover of the DIP switch.
We suggest that you use a screwdriver to set the DIP switch to the desired
position.
