secure_area_audio_status

This data flow contains operational status (state of the device, configuration, and fault data) information from audio systems located in secure areas frequented by travelers, such as transit stops, rest areas, park and ride lots, modal interchange facilities, on-board a transit vehicle, etc. as well as areas typically away from travelers such as tunnels, bridges, and roadway infrastructure. This data flow contains an indication that a fault has been found with the collection of audio data by the device and is used by the receiving process to monitor the health and current status of field equipment. The data flow consists of the following data items each of which is defined in its own DDE:

list_size + list_size{station_id
+ device_identity
