Two other options unique to the DVS168 protocol are also provided.
1. To send just the EAS alert audio message, instead of the EAS FSK header and EOM
audio and attention audio, use the provided checkbox. Before using this option, it is
important to make sure your local EAS plan allows the FSK audio to be discarded.
2. Alert duration data format: typically in minutes, some DVS-168 interpreters have
coded this differently. The selector provides two other interpretations.
The DVS168 protocol does not provide a programmable schema. For DVS168, the data
schema is predefined and the schema selection is not displayed. As with the other EAS
NET protocols, the Video Start Delay time, the Duration Extension time, and FIPS based
net alert triggering are all configurable.

DVS168/EARS operation
- When a forwarded/originated EAS alert is to be sent using a
DVS-168 EAS NET client, a TCP socket is temporarily opened from the EAS device to the
DVS-168 remote host. If this succeeds, and the alert is a non-national alert (and FTP is
enabled), a WAV file of the EAS audio and a text file of the alert details are FTP’d to the
DVS-168 remote server host. Then a control message is sent over the TCP socket that
describes the alert and provides names for the data files. For non-national alerts, this
is the only notification by TCP needed. For EAN and NPT national alerts, the audio is
not generated or sent, since EAN/NPT alert audio is live and of undetermined duration.
When the alert ends, a second control message is sent over the TCP socket to signal the
end of the national alert. After this, the socket connection is “torn-down.” The Opera
-
tion Log will log each of these actions and their success or failure.
