DCC Alert

N54 — Dual Band CH Alert

SMETS applicability: SMETS2 or later

Trigger & context

When and why this alert fires

Event
A Dual Band CH Device generates a Device Alert as defined by GBCS
Trigger
Dual Band CH Device Alert received by the DSP Access Control Broker as defined by GBCS section 16.1, being one of: Alert Type 1: 0x8F21 (Duty Cycle fallen below Normal-Limited Duty Cycle Threshold), 0x8F22 (Critical Duty Cycle Action Taken), 0x8F23 (Duty Cycle fallen below Limited-Critical Duty Cycle Threshold), 0x8F24 (Regulated Duty Cycle Action Taken), 0x8F25 (Duty Cycle fallen below Critical-Regulated Duty Cycle Threshold), 0x8F27 (Sub GHz Channel Scan initiated), 0x8F29 (Three Lost GSME Searches Failed), 0x8F2B (Sub GHz Channel not changed due to Frequency Agility Parameters). Alert Type 2: 0x8F20 (Limited Duty Cycle Action Taken), 0x8F26 (Sub GHz Channel Changed), 0x8F28 (Sub GHz Channel Scan Request Assessment Outcome), 0x8F2A (Sub GHz Configuration Changed), 0x8F2C (Message Discarded Due to Duty Cycle Management), 0x8F2D (No More Sub GHz Device Capacity).
