About This Guide 
Introduction 
The Federal Communications Commission (FCC), the National Weather Service, and 
local authorities send emergency alert messages (EAMs) to service providers who 
broadcast these messages to television subscribers. These messages include regular 
tests of the Emergency Alert System (EAS), as well as messages that warn of 
dangerous conditions such as thunderstorms, floods, tornadoes, hurricanes, and 
earthquakes. 
The FCC requires that service providers receive and send Emergency Alert Messages 
(EAMs). In addition, the FCC requires that service providers conduct weekly and 
monthly tests of the Emergency Alert System (EAS). By conducting weekly and 
monthly tests of the EAS, service providers ensure the reliability of their EAS 
equipment so that subscribers can receive national, state, and local warning 
messages about emergency situations. 
This guide describes the digital EAS and the various EAS vendor components that 
interface with our IP Service Delivery System (ISDS) and the IPTV Services Delivery 
Platform (ISDP). 
 
Purpose 
After reading this guide, you will be able to configure, operate, maintain, and test 
EAS components on the ISDS and the RNCS. Properly configuring, maintaining, and 
testing your system lets you follow FCC regulations by receiving and then sending 
EAMs to subscribers through a correctly configured and fully automatic EAS 
process. If your system does not perform as expected, this guide also includes a 
troubleshooting section so you can quickly restore your system to full operation.  
 
 
Scope 
You have the option of configuring your EAS as one of the following: 
 
A centralized configuration, where the central ISDS sends the EAMs to all the 
subscribers' set-tops. 
 
A distributed configuration, where the central ISDS and each Regional Network 
Control Server (RNCS) delivers the EAMs to the subscribers' set-tops. 
 
 
Software Requirements 
This document is valid for the ISDS 2.3 and later software releases.
