Question: In a non-virtualized RAN scenario, where all Managed Elements (ME) are deployed on Physical Network Functions (PNF) within the operator's premises, how does the operator typically collect Power, Energy, and Environmental (PEE) parameters from Network Elements (NE) equipped with external sensors?
Option 1: Through an Operations, Administration, and Maintenance (OA&M) channel.
Option 2: Using a dedicated channel specifically for external sensor data transmission.
Option 3: By manually retrieving logs from each Physical Network Function (PNF).
Option 4: Via a shared network interface used for general operational traffic.
Explanation: In the context of non-virtualized RAN and the collection of PEE parameters, a dedicated channel is utilized for collecting PEE parameters from Network Elements with external sensors. This approach ensures segregated and possibly more secure or reliable transmission of sensitive environmental and energy consumption data.
