ABSTRACT:
Providing an audible feedback feature giving the user the ability to audibly monitor the progress of a data connection over a digital wireless channel. Audible tones generated within a base station and received from a telephone network are encoded within the base station and transmitted over the digital wireless link to a mobile unit. The mobile unit decodes the signal received from the base station and provides the audible tones to a user. The user can thus monitor the success or failure of the data connection.
