Connecting RAN equipment to the NT8D14 Universal Trunk Card (typical)
Recorded announcement machines store prerecorded voice messages
that are played back to the trunk units to which they are connected. Most
commercially available announcement machines store recordings digitally,
although some drum and tape units are still in service.
An announcement machine can provide one or more channels and
each channel can be prerecorded with a different message. Some
announcement machines also provide a Special Information Tone
(SIT) capability. These tones are inserted at the beginning of intercept
messages (such as "Your call cannot be completed as dialed. Please
check the number and try again.").
