Abstract
A method and apparatus is described that provides for switching active data connections from one processor to another processor without significantly interfering with the transmission of the data. The data may be voice calls and the processors may be DSPs residing on a voice processing module. A DSP resource allocation algorithm may be used to load share the data by selectively moving an active voice call currently being processed on one DSP to another DSP having sufficiently available processing power, without interrupting the prevailing service. The liberated DSP may then be used to process a new active voice call. By using the DSPs to load share, the number of simultaneous active voice calls supported by a voice processing module may be increased.
