Cisco DNCS System Release 2.8.1 3.8.1 4.3.1 User Guide

Important: This process describes how the digital EAS works in a system that uses a Regional Control System
(RCS). The topic 

In an RCS, processes that manage EAMs reside both on the DNCS and on each remote RNCS/LIONN. Where
the EAM originates determines how the EAM is processed. When the EAM originates from an Emergency Alert
Controller (EAC) in the central site, the EARS process on the DNCS sends the MMMServer process an Event
EAM.

For more information on how an EAM is processed at the central site, see the following illustration. When
reviewing this illustration, keep in mind that the equipment that receives the EAM  the RF receiver and the
Emergency Alert Controller (EAC)  is provided by a vendor other than us.
