"In the cabin" means passenger cabin, where ANP/RNP isn't displayed. "In the cockpit" is more accurate.

How RNP's onboard performance monitoring and alerting system is represented in the cabin

I'm trying to understand what is exactly onboard performance monitoring and alerting system related to RNP. Does it display some extent of deviation or just beeps as alarm? And if that system exists only in RNP, so how can pilot be sure that he performs RNAV1 (for example) correctly?
