A general purpose, remote access, computing system is described, that employs twelve-key keyboard telephones as terminals.Audio output is provided directly to the telephone terminah, but the system will normally be used in conjunction with remotely located high speed printing devices.The system is a compatible extension of an existing batch processing system.A significant element of Ihe system is a scheme for transmitting alphanumeric information by single strokes on a numeric keyboard.The programmed scanner uses context to eliminate the ambiguity in transmission.
