The Digital Announcement System (DAS) is a functional unit of intelligent networks
(IN) with which announcement services can be played into the voice connection. Digital Announcement Systems use announcement memories in which the announcements are digitally stored and called up as required.
Announcementservices can be used in a variety of ways, such as for weather news, traffic situations, sports results and much more.
If the DAS systems are designed exclusively for voice announcements, they are referred to as Voice Recorded Announcement Service (VARS).
