Detailed Description

Multicast module with multi-instance support and active trigger mechanism.

This module handles multicast alarm distribution. It manages the correlation between tone-RICs (recipients) and text-RICs (message content), ensuring reliable alarm delivery even in complex multi-frequency scenarios.
