Abstract

See full text

Apparatus for eliminating the need to repeat dial the same area code on a given long distance call. The apparatus detects when a subscriber wishes to implement a long distance call. Upon detection of the start of a call, the apparatus automatically displays the last area code dialed. The subscriber if desiring the last area code merely dials seven digits. The apparatus recognizes that the subscriber has selected the last area code to cause the last area code dialed to be transmitted prior to the transmission of the seven digits thereby completing a telephone number. If the subscriber does not wish to utilize the last area code dialed he first dials a '1' and then dials in ten digits and the proper digits are transmitted with the area code digits being replaced in the area code storage memory. The apparatus is particularly adaptable for use by cellular subscribers due to the fact that it reduces the number of digits dialed, saves dialing time and is therefore inherently safer to utilize while operating a vehicle.
