Connection factor (AK, RK, MK)
The number of connectable C-NET devices and the max. line length depend on the
connection factor of the terminated line devices. The maximum number of 126 C-
NET devices per loop and the max. length of line of 3300 m can be greatly reduced
depending on the type and volume of line devices used.
