Abstract
A method and system which provide for repertory dialing of a telephone. The repertory dialing system includes a repertory key, means for detecting when the repertory key is pressed and released, a memory having a first memory location and a second memory location, means for accessing or programming a first repertory number at the first memory location when the repertory key is pressed and released one time and means for accessing or programming a second repertory number at the second memory location when the repertory key is pressed and released twice. The system determines whether the memory locations are being programmed or accessed based on the timing of the presses and releases. The method includes the steps of pressing and releasing the repertory key one time to access or program a first repertory number, and pressing and releasing the repertory key two times to access or program a second repertory number. Whether the repertory numbers are accessed or programmed depends upon the timing of the pressing and releasing.
