Abstract
A programmable dialler for a cellular telephone instrument allows telephone calls to be made only to specific, preprogrammed telephone numbers by operation of one or a sequence of keys on the instrument. The telephone numbers are deep embedded in the telephone instrument and cannot be changed by the user. The preprogramming may either be carried out by the instrument manufacturer, or may be carried out by a licensed programmer with the aid of a dedicated programming interface.
