Abstract:
A network device for establishing communication between a first communication unit and a second communication unit through a packet switching network comprising:a DSP array responsive to signals having coupled thereon voice, fax or data information for digitizing the information and converting the same to packets to form digitized packets of information; a routing engine for transmitting the digitized packets through the packet switching network; a DSP memory coupled to the DSP array for storing said digitized packets; a packets memory coupled to the routing engine for storing a plurality of said digitized packets for transfer thereof to the routing engine; and a memory interface unit coupled between the DSP memory and the packets memory for consummating the transfer of the digitized voice packets from the DSP memory to the packets memory for transfer thereof to the routing engine and accumulating a predetermined number of the digitized packets in the packets memory prior to effectuating the transfer to the routing engine, wherein minimal intervention for transmitting the digitized packet is required by the routing engine thereby allowing the routing engine to tend to higher level tasks resulting in a reduction in system latency.
