Priority Override Busy Signaling

It is visually indicated at your intercom station if you can override a busy connection. Only a subscriber with a higher priority can interrupt an existing connection.

You can override a busy connection when the LED on your intercom station blinks with a frequency of 900:100 (900 ms on / 100 ms off).
