The IDT77252 NICStAR
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 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
