control pulses every 7 or 14 seconds (at the start of the announcement
period). A number of trunks can be connected to one announcement
machine.
The Universal Trunk Card does not support the Code-A-Phone 210DC
announcement recorder.
Recorded announcement machines
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 may 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."
Figure 194 "Connecting RAN equipment to the NT8D14 Universal Trunk
Card (typical)" (page 580)
shows a typical connection from a single
announcement machine channel to unit 0 on a universal trunk card.
