Generation ATM OC-3/DS3 Adapters

The WANic 1000 Line is ATM OC-3 adapters with traffic management for the PCI bus
N/A000 Line is ATM OC-3 adapters with traffic management for the PCI bus. Featuring a 155 Mbps OC-3 interface, N/A000 complies with ATM Forum Specification UNI 3.1 and TM 4.0. Based on an advanced ATM Segmentation and Reassembly Controller (A-SAR) which is designed to optimize PCI bus occupancy and maximize performance under short packet conditions, N/A000 supports AAL0, AAL1, AAL2, AAL3/4, AAL5 and raw cells.

The traffic management co-processor within the A-SAR supports Constant Bit Rate (CBR), Variable Bit Rate (VBR), Unspecified Bit Rate (UBR), Available Bit Rate (ABR), Guaranteed Frame Rate (GFR) and Generic Flow Control (GFC). The xBR traffic management block automatically schedules each VCC according to user assigned parameters.

Supporting 32,000 VCC, N/A000 supports 155 Mbps full duplex operation for packet data unit (PDU) sizes as small as two cells. In the half duplex mode, the product supports burst rates of 200 Mbps. The front-end features support SONET STS-3c or SDH STM-1 with built-in performance and alarm monitoring.
