network access products Endstation ServiceSAR Controller RS8235 Endstation ATM xBR Service Segmentation and Reassembly Controller (ServiceSAR) Conexant’s RS8235 offers endstations all of the xBR service categories in a highly integrated 3.3V CMOS package. The RS8235 architecture complements the RS8234 edge SAR feature set, so that software reuse is maximized. The RS8235 directly connects to Conexant’s RS8251 PHY device for a total NIC solution. The RS8235 supports a similar feature set to the RS8234 edge SAR, but in a reduced footprint. System designers can therefore offer a common traffic control and host interface to a new market segment. Integrated Management The RS8235 complies with ATM Forum specifications UNI 3.1, T.M. 4.1 and all other relevent standards. The RS8235 provides integrated traffic management for all service categories, including constant bit rate (CBR), variable bit rate (VBR1, VBR2, and VBR3), real-time VBR, unspecified bit rate (UBR), available bit rate (ABR), guaranteed frame rate (GFR) (guaranteed MCR on UBR VCCs), and generic flow control (GFC). The xBR traffic management block automatically schedules each VCC according to user-assigned parameters to maximize line utilization.
