Abstract: Bi-directional streaming of telephony data such as Pulse Code Modulation (“PCM”) and Time Division Multiplexing (“TDM”) data to a host processor via a standard personal computer interface is disclosed. PCM/TDM data is moved via a hard disk drive Intelligent Drive Electronics (“IDE”) interface, a hard disk drive Small Computer System Interface (“SCSI”) interface, a Dual In-line Memory Module (“DIMM”) interface, or a Single In-line Memory Module (“SIMM”) interface. A small board is installed on the computer motherboard that has an SCbus/CTbus/MVIP bus connector, an SCbus/CTbus/MVIP bus switching ASIC, a control processor, memory, and associated logic, and at least one of an IDE, SCSI, DIMM, or SIMM interface. The control processor receives the PCM/TDM data from the bus, formats it to resemble a memory device, and then initiates a direct memory access (“DMA”) to transfer the PCM/TDM information to the host processor.
