DCN limit 1; maximum control capacity is not exceeded; this example contains only 78
active devices where 245 is the maximum.
DCN limit 2; maximum power capacity is not exceeded. The corrected power does not
exceed the maximum power of 85 W. The corrected power is however close to the
maximum, using longer extension cables or adding more discussion devices, or trunk
splitters, will exceed the maximum a DCN socket can deliver.
DCN limit 3; maximum Loop-throughs of active or passive devices is not exceeded. The
limit is 25, the highest number of loop-throughs in this example is 7.
DCN limit 4; maximum tap-off connections is not exceeded. The limit is 4, the highest
number of loop-through connections in the example is 1.
DCN limit 5; maximum cable length is not exceeded. The limit is 250 m, the longest
distance from the central control unit to the furthest device in this example is only 51 m.
