Abstract

Many modem telephone and key systems are now equipped with a numeric display, The numeric display is used for displaying the telephone numbers which are stored in the telephone unit's memory or for displaying the number that is being dialed by the user. Currently fixed and cellular telephones offer facilities such as 'secrecy: 'last number m-dial (LNR): 'notepad' and 'mem- ory: The LNR and Memory facilities also require a stor- age operation for telephone numbers. The numeric dis- play showing these dialed numbers though, could also offer further uses for the telephone user, as proposed in this invention.

FACILITY TO AMEND TELEPHONE NUMBERS PRIOR TO DIALING

by Antony John Wray and Steve Valentine

INTRODUCTION:

  Many modem telephone and key systems are now equipped with a numeric display, The numeric display is used for displaying the telephone numbers which are stored in the telephone unit's memory or for displaying the number that is being dialed by the user. Currently fixed and cellular telephones offer facilities such as 'secrecy: 'last number m-dial (LNR): 'notepad' and 'mem- ory: The LNR and Memory facilities also require a stor- age operation for telephone numbers. The numeric dis- play showing these dialed numbers though, could also offer further uses for the telephone user, as proposed in this invention.

  Currently most telephone calls are business calls, where a significant amount of time is spent accessing outside limes, dialing International and / or STD codes followed by say the company's prefix and then the exten- sion number of the person being called. Generally, should this line be engaged or there be no answer and an alter- native extension number be adequate, then the whole dialing code and number has to be re-entered. This is also the case should a wrong digit be entered in the dialing stage; assuming that the number being dialed is not one called up from its memory,

  An improvement to this existing technology is a facil- ity incorporated on the Motorola Microtac cellular tele- phone, which has the option of deleting / adding digits to those displayed Although this is an improvement over having 'No' digit amendment facility it does not provide the flexibility of amending specitic digits which have been entered into the telephone's display.

  The invention detailed below proposes a simple method to amend specific digits of the number to be dialed. This amendment can be made:
i) during the number entry, where a digit input was in error,
ii) atler the whole number has been input and it is then realized by the user that a previous digit entered was in error,

iii) the number has been dialed, the call connected and an alternative number (say a different extension) was suggested(r) or if the line was engaged and again a diierent extension would suffice or
iv) after the whole number has been input and then the user realizes that a digit has been 'omitted' after entering the number.

InFrequently when telephone numbers within an existing

STD code are to be expanded to allow for the increased demand for telephones within that area, an extra digit is placed prior to the existing telephone number. The user is only informed of this change once the number has been dialed. The user therefore has to re-dial the whole number; whereas with this invention the user can just enter the additional digit wherever required.
