Abstract:
1. An apparatus for receiving a common-part sublayer packet (CPS-packet) on an ATM adaptation layer (AAL) configured connection within an asynchronous transfer mode (ATM) system comprising a digital signal processor (DSP) sub-system and a host processor, said apparatus comprising: a first direct memory access unit having an output coupled to said DSP sub-system and operably configured to forward data stored in a phone line memory unit to said DSP sub-system, said phone line memory unit corresponding to a channel identification (CID); and a second direct memory access unit having an output coupled to said host processor and operably configured to forward data stored in a host memory unit to said host processor, wherein data is forwarded to said host memory unit in response to CID and user-to-user indication (UUI) filtering.
