NCB-30N is a dual purpose pear-push nurse call switch serving both the infotainment system ( 2-way full-duplex voice communication/Nurse Calling) and the redundant Nurse call system( Nurse Calling/Cancelling). It connects to the All-in-One via an 8-pin military socket and a medical grade coiled cord. NCB-30N ensures that the patient is always connected to the hospital staff even in case of the LAN failure.
