ABSTRACT:
A call processing method and apparatus for erasing a digit stored in memory in response to a "delete" signal generated by a caller station is disclosed. A protocol is provided for a switching system to recognize the "delete" signal as a command to erase a last stored input digit. In a telephone system, a subscriber's telephone is equipped with a "DEL" key to facilitate the generation of the "delete" signal to erase the last digit (e.g., a misdialed digit) that the switching system received during the process of dialing a telephone number from the caller station.
