Abstract (en)
[origin: WO0004696A1] A message retrieval system is arranged to allow control functions to be carried in out-of-band signalling channels, thereby allowing a reduced bandwidth to be required for message storage and retrieval. In particular, storage or retrieval can be carried over a simplex broad bandwidth link, as no broad bandwidth signal is transmitted in the reverse direction. When a user (3) accesses the message facility (1), a signalling connection (7) is first set up. The message facility (1) may use calling line identity to identify which messaging address is required, and whether the calling terminal has the out-of-band signalling capacity. A simplex voiceband connection (6) is then set up from the message banck (1) to the terminal (3), and prompts are transmitted over this connection to the user. The user, on receiving such prompts responds with signals entered on the keypad or other data entry device of his terminal (3), and these are transmitted over the signalling connection (7) to control the further operation of the message bank, and in particular to cause it to transmit selected messages (step 78) over the wide bandwidth link (6) to be received by the user (3).
