Description / Abstract:

Increasingly, telecommunications services are making use of letters, as well as numbers, on numeric keypads for tasks such as directory, dial-by-name, entry of alphabetic numbers, and the like. In addition, it is recognized that many users of telecommunication services prefer to use letters instead of digits to code and remember numbers. Hence, there is a need for a standard allocation of letters to the keys of numeric keypads used for telecommunications.
