Abstract: A voice server module for an ATM switch is provided and generally includes an interface block which receives and multiplexes high speed preprocessed data, a voice processing block which compresses voice data and which is coupled to the interface, an ATM adaptation layer (AAL) processor which receives data from the voice processing block and which formats the data into ATM AAL2 format, and a management processor which configures the interface block, the voice processing block, and the AAL processor. The voice processing block includes an array of digital signal processors (DSPs), including at least two and preferably eight rows and at least two and preferably eight columns. Each row is also provided with a field programmable gate array (FPGA). Data transmission between (to and from) the FPGAs and DSPs is according to a frame. The FPGAs are utilized to direct data received from the interface block and from the AAL processor to appropriate DSPs for processing.
