The number of permissible terminals per system depends on the power require-
ments of the individual terminals. To check the power requirements refer to Tab. 33
for details of the average power requirements of the terminals.
The total power requirements of all connected terminals must not exceed the avail-
able power output of the power supply.
Note
The actually required power supply depends strongly on the call traffic,
the wire diameter and the line length to the connected terminals. The val-
ues in the following table are average values under the following
assumption:
– Phones traffic volume: Call Connection 38%, Ringing 2%
– SB-4+ radio unit: Active call connection on 2 channels
– SB-8 radio unit: Active call connection on 4 channels
– Background lighting Aastra 5380: 30% active
– LEDs on terminals and expansion key modules: 20% active.
– Wire diameter: 0.5 mm
– Line length: 200 m
The table below shows the average power requirements of the terminals for a line
length of approx. 200 m and a wire diameter of 0.5 mm.
