Abstract
A device according to the invention is compatible with conventional magnetic tape loggers. Such a device is termed a message repeater, and it records and replays audio signals forming messages on a message channel, such as a telephone line or a radio channel. The message repeater includes circuits for converting the audio signals on a particular channel into corresponding digital signals and circuits for storing the digital signals. The message repeater also includes circuits for selectively recalling the signals that were stored and circuits for converting the signals that were recalled into analog audio signals. Messages on the selected message channel may be recorded and later replayed by the message repeater. Preferably, the message repeater includes a display with indications of the relative locations and lengths of the stored messages as well as a cursor or index. Furthermore, the message repeater preferably permits a selected message to be saved, thereby allowing the selected message to be replayed at the convenience of the operator. Additionally, the message repeater advantageously has fault detection circuits for determining if a fault has occurred in the other circuits.
