<p>Apparatus is shown which eliminates 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 (21). Upon detection of the start of a call, the system automatically displays the last area code dialed (16). The subscriber if desiring the last area code merely dials 7 digits. The system 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 7 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 10 digits and the proper digits are transmitted with the area code digits being replaced in the area code storage memory (15). The system is particularly adaptable for use by cellular subscribers due to the fact that it reduces the number of digits dialed, and saves dialing time.</p> |
