Extension cables

Adding an extension cable longer than 20 m (66.0 ft) to a trunk/tap-off has a direct effect on
the available power for the components connected in the daisy chain. A component can be a
Discussion Device or an Extension Unit.
Use the following table to determine the total number of components that can be connected
to a trunk/tap-off when one or more extension cables are connected to that trunk/tap-off.
