The ABR SAR performs both the ATM Adaptation Layer (AAL) Segmentation and Reassembly (SAR) function and the ATM layer protocol functions. A Network Interface Card (NIC) or internetworking product based on the ABR SAR uses host memory, rather than local memory, to reas- semble Convergence Sublayer Protocol Data Units (CS-PDUs) from ATM cell payloads received from the network. When transmitting, as CS- PDUs become ready, they are queued in host memory and segmented 32 33MHZ IDT77252 155Mbps PCI ATM ABR SAR PHY Rx UTOPIA Bus Tx UTOPIA Bus Utility Bus 8 8 82 2 155Mbps 16K x 32 to 512K x 32 SRAM EEPROM 32 80.0MHZ OSC.
