The IDT77252 NICStARTM is a member of IDT's family of products for Asynchronous Transfer Mode (ATM) networks. 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 reassemble Convergence Sublayer Protocol Data Units (CS-PDUs) from ATM cell payloads received from the network. When transmitting, as CSPDUs become ready, they are queued in host memory and segmented |
