13.2.2 AALx Voice Centric Operation—(EXTERNAL_SCH = 1)
28236-DSH-001-B
No scheduling is performed by the Scheduler block in this mode. For each
processing loop through its state machine, the Segmentation block monitors the
cell-available counters (priority is round-robin) to determine if any have data
available for transmission. If so, the PCI address for the corresponding AALx is
looked up from internal memory, and the entire cell (52 bytes) with modified
ATM Header word is read across the PCI bus.
No connection setup is required in this mode; the user must do the following:
• Write the AALx’s FIFO buffer PCI address to internal memory.
• Write ATM header into VCC entry.
The AALx traffic stream is enabled as the AALx strobes HFIFOWRx.
