If you have problems with your digital EAS equipment, please refer to the 

appropriate documentation provided with your equipment, or contact the 

manufacturer. 

 

This document refers to the manufacturers and distributors of digital EAS 

equipment used by our customers. The Emergency Alert Controller (EAC) resides at 

your site and serves as an interface between your EAS receiver and the ISDS. The 

following companies manufacture EAC solutions that are known to work with the 

ISDS: 

 

Sage Alerting Systems, Inc. (MegaHertz) 

 

Trilithic, Inc. (Trilithic) 

 

Frontline Communications (Frontline) 

 

Monroe Electronics (Digital Envoy) 
Note: The Monroe Electronics EAS uses an encoder/decoder manufactured by 

the HollyAnne Corporation.  

 

This section provides information to help you troubleshoot your Emergency Alert 

Controller (EAC) configuration. 
Important: Some configuration and troubleshooting information is provided for 

third-party equipment (such as MegaHertz, Trilithic, Monroe, and Frontline). 

However, you should always refer to the documentation that comes with that 

equipment when you configure or troubleshoot that equipment. The scope of this 

information is to make sure that equipment can communicate with our equipment, 

not to be a comprehensive configuration and troubleshooting guide for third-party 

equipment. 

 

Troubleshoot the EAC PC 
Important: When troubleshooting your EAC, if any of the settings are incorrect, go 

to the section pertaining to your system in Verify Your EAS Equipment 

Configuration (on page 5), and follow the verification procedures listed there. If you 

need additional assistance, call Cisco Services. 
Use the following information to troubleshoot your EAC configuration.
