Abstract
A control circuit automatically presents on a display public telephony system telephone numbers using a presentation format that is standard for the public telephony system and private-exchange telephone numbers using a presentation format that includes a non-numeric private exchange modality indicator. By one approach, the non-numeric private exchange modality indicator consists of a single alphabetic character (such as, for example, the alphabetic character “X”) which may, if desired, by presented contiguously with the remainder of the private-exchange telephone number.
