Abstract (en)
[origin: WO9939469A1] An ATM switch voice server module (18) has an interface (20) for receiving/multiplexing high adaptation layer (AAL) processor (40) which formats uncompressed data into AAL1 format and compressed data into AAL2 format, a management processor (50) which configures the interface (20) and the processors (30, 40), and preferably a data bus for carrying compressed voice data and a flag bus for carrying flags generated by the voice processor (30) relating to the voice data which are both coupled to the AAL processor (40), with the voice processor (30) ignoring all but the voice data portion of the data stream and the AAL processor (40) ignoring the voice data portion of the data stream. The voice processor (30) includes an array of digital signal processors (DSPs), including a plurality of rows and columns, with each row also including a field programmable gate array (FPGA).
