发明名称 METHOD AND APPARATUS OF PROVIDING AUDIO FEEDBACK OVER A DIGITAL CHANNEL
摘要 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 (80) and received from a telephone network (30) are encoded within the base station (80) and transmitted over the digital wireless link (160) to a mobile unit (60). The mobile unit (60) decodes the signal received from the base station (80) and provides the audible tones to a user. The user can thus monitor the success or failure of the data connection.
