It is possible, however, to calculate the exact number of Call
Forwarding Devices (without power supply) that can be arranged
within the system, knowing the type and the number of indoor stations
that you wish to use:
1. In the case of a system with 2Voice cable or HVV05-F cable 1
mm
2
(AWG17) or single wire, 1 mm
2
(AWG17)
CFSAmax = [127 – PI1 – (2*PI2) – CF] / 8
2. In the case of a system with Cat5 cable or telephone wire pair
with Ø 0.6 mm (AWG22)
CFSAmax = [127 – PI1 – (2*PI2) – CF] / 30
Where:
CFSA
: is the result that expresses the maximum number (rounded
down) of Call Forwarding Devices without power supply
that can be powered off the system BUS.
PI1
: number of indoor stations (video door phones/door
phones) mod. Miro or video door phones mod. Aiko/Folio
present in the system.
PI2
:
number of indoor stations (video door phones mod. Modo
or PABX interfaces) present in the system.
CF
: Number of Call Forwarding Devices present in the
system.
