Abstract
In an audio-digital telephone interface system, a control selectively prompts a caller with oral instructions to selectively provide; control signals, digital data means (numeric) or audio signals. A data cell is loaded in accordance with an operating program of the control and the resulting data packet is classified, as depending on the presence of audio signals. Data packets are returned to storage, as for subsequent off-line processing. The illustrative format receives and organizes mail order data from callers.
