Abstract
Abstract An advanced telephone dialler has been described, incorporating a fast retrieval and dial telephone directory. The system simplifies the use of the telephone directory by using a single sliding or rotary key for scanning and selection of the name and number to be dialled and one button for speed dialling of the selected number. The name and telephone number of the selected person are simultaneously displayed on a character display and a normal telephone keypad has been used for entering both letters for the name and digits for the number into telephone directory's memory. A short cut dialling has been also provided by simply using the sequential order number of the person to be dialled from the telephone directory's memory. An option has been provided for checking the incoming calls numbers with the telephone directory of the system and not only displaying the name of the calling person and its number if they have been found in directory. In addition the telephone directory memory is divided into pages each page having its own access code and the option to be locked or unlocked. If a selected page has been locked the access is denied unless a proper access code for this page has been entered. In the case of the calling number identification feature, in addition to the name of the calling person if it is in the memory, the system displays the name of the person to whom the page, where this number resides, has been assigned. The application is targeted for heavy traffic business or personal phones, family telephones, cellular phones and as a part of an office or home automation system.
