Abstract
A system for adapting a transmission rate of an audio signal transmitted over a TDM communications link from a source to a destination includes a first variable-depth storage component and a first processor at the source, and a second variable-length storage component and a second processor at the destination. The first storage component stores the audio signal, and the first processor selectively withdraws the signal from the first storage component. The first processor encapsulates the signal into packets and transmits the packets via the TDM link. The second processor receives the packets, removes the audio signal, and deposits the signal into the second variable-depth storage component. The first processor selectively withdraws the audio signal as a function of the amount of data in the first storage component, and the second processor selectively withdraws the audio signal as a function of an amount of data in the second storage component.
