Configuring EAS Messages
The FCC has defined 54 EAM message types, which are listed on the FCC web site.

The configuration of an EAM specifies how the set-top presents the alert. By default,
all EAMs use the same configuration, which means that they are presented by the
set-top in the same way. On a set-top, the default configuration displays a red
banner at the top of the screen and the text for the message is shown in white. If the
message is sent with audio content, it is played instead of the normal program audio
while the message is active.

The ISDS lets you configure an alternate behavior for each EAM by modifying one of
the existing MMM configurations and by associating an EAM configuration with the
new configuration. For example, if you want a Child Abduction Warning (e.g., an
Amber Alert) to force tune the set-tops to a local news service, you would use the
force tune configuration for that EAM.

Although the ISDS provides the capability to have a unique configuration for each
type of EAM, most operators only use a few configurations (one for messages that
will use the banner, a second for force tuning, one for required weekly tests and
finally one for required monthly tests). You should check current FCC and local
requirements to determine what setting are most appropriate for your operating
environment.
