Abstract:
1. A Voice over ATM apparatus for transmitting packetized data received from a digital signal processor (DSP) sub-system and a host processor in an asynchronous transfer mode (ATM) system, said apparatus comprising: a codec; a Voice over ATM (VoA) phone having a physical phone line identifier, said Voice over ATM (VoA) phone coupled to said DSP subsystem and said codec; a first Direct Memory Access (DMA) unit dedicated to said DSP sub-system and configured to fetch a voice packet from said DSP sub-system, wherein said voice packet includes said physical phone line identifier; and a second Direct Memory Access (DMA) unit dedicated to said host processor and configured to fetch a signaling and management packet from said host processor, wherein said signaling and management packet includes a transmit channel identifier a router identifier table having a memory for storing channel pointers, wherein said physical phone line identifier indexes to a particular channel pointer which identifies a transmit channel in a channel state table; and wherein said channel state table having a memory for storing channel information for a plurality of transmit channels, said channel information including a pointer to a transmit buffer, wherein said voice and signaling and management packets identified to a particular transmit buffer are forwarded to said particular transmit buffer for further processing and transmission to a destination port.
