mounted on the teleCARE IP Room Controller 3 (NIRC3).

The NIVP has four half duplex speech channels allowing four speech sessions at the same time, one
speech session for each room bus. Each speech channel has an LED to indicate that the speech
direction is switched towards the speech module on the room bus. The NIVP allows existing non
speech teleCARE IP installations using the NIRC3 to be upgraded to teleCARE IP with speech.
The following illustration shows the NIVP voice piggyback module mounted on the NIRC3:
