The 3X-DEFPA family of FDDI NICs uniquely provide the ability to auto-negotiate to operate in full-duplex mode when connected point-to-point with another DEFPA, or cooperating FDDI switch. Full-Duplex mode eliminates the token, and allows the DEFPA to simultaneously transmit and receive packets without the latency associated with token rotation. Full-Duplex mode allows the DEFPA to sustain aggregate data rates in excess of 100Mbps. The 3X-DEFPA uses linked-list, scatter/gather, bus-mastering technology to maximize throughput and optimize host system utilization.
The 3X-DEFPA features a robust PCI Plug-and-Play capability and PCI 2.2 support for conflict-free auto configuration. The 3X-DEFPA will automatically negotiate to operate in either half (normal token rotation mode) or full-duplex (no token) mode, and to configure itself for SAS, DAS, or dual-homed (auto port fail-over) operation. LEDs indicate link status, configuration, and network activity for "at-a-glance" troubleshooting. Designed with quality and investment protection in mind, the 3X-DEFPA family of FDDI NICs meet all of Compaq's demanding design and manufacturing standards. Surface-mount technology, ASIC-based hardware, state-of-the-art manufacturing facilities, a top-notch quality inspection, and testing provide the reliability and quality you expect from a Compaq product.
