2. MULTIPLE SPEECH PATHS - OPTION 1 DIGITAL
On multi-entrance systems multiple speech paths can be achieved by fitting extra distribution nodes and
wiring the telephones/video phones to multiple nodes. The example below shows a 2 entrance digital system
with 2 speech paths, i.e. both door panels can be used at the same time to call different flats.
Note: for 3 door panels with 3 speech paths telephones would need to be connected to 3 distribution nodes.
