I'm new Alcatel-Lucent Pre-sale using Actis I want to order crystal OXE without Alcatel Power supply option ( rectifier and batteries). my question how to calculate Power needed for this equipment.
I talked about - Display/ Technical config - Power supply.
You can see - consumption, heat dissipation for your system. And calculation for rectifier/battery (for central area, for peripheral areas).
Nor clear what you want.
Tools/Power supply calculation - for Consumption and autonomy what you want - tool will calculate battery and rectifier.
If you want to know consumption for your PBX - calculate PBX in Actis. Calculated consumption you can see in Display/Technical config - Power supply.
