1.DESCRIPTION

This Engineering Technical Information (ETI) Bulletin describes the steps necessary for the installation of an AEC Messenger, Model 212 Plus, dual line announcer for operation with an ECR-E ETU. The delayed announcement feature may be desirable when using a Hunt Group in conjunction with DIT or ANA to provide UCD. Any time all stations in the Hunt Group are busy or unable to answer, the Delay Announcer can be used to provide one (1) or two (2) delay announcements instructing callers to wait or call back later.
