Operational Levels are designed to improve the responsiveness of the SCN during emergencies. SCN Operational Levels are defined as follows:
- Operational Level 3 - Conditions normal. No emergency exists. The ten-channel SCN may be used by SHARES station personnel for training and non-emergency operations.
- Operational Level 2 - Emergency potential exists. Non-emergency operations on the SCN suspended. SCN monitoring increased. Communications operations established on the National and Regional nets to receive Stations Availability Reports.
- Operational Level 1 - Emergency exists. SHARES message support required. National and regional nets maintain full-period operations to receive Station Availability Reports, to list SHARES message traffic, and to coordinate the processing of SHARES messages.
