1 INTRODUCTION The 3Com® TokenLink® Velocity™ ISA network interface card (NIC) is a high-performance card for PCs with an Industry Standard Architecture (ISA) bus or Extended Industry Standard Architecture (EISA) bus. This NIC is referred to as the 3C319 NIC in this guide. High-Performance Features The 3C319 NIC is designed for high network performance and trouble-free operation. This section describes the performance features of the 3C319 NIC.
1-2 CHAPTER 1: INTRODUCTION For example, the 3C319 NIC begins writing the first portion of a data frame to the network before it has completed reading it from PC memory. Full-Duplex/Dedicated Token Ring Support Full-duplex/Dedicated Token Ring (DTR) is an enhancement to the IEEE 802.5 standard that allows a 16 Mbps switch port to be dedicated to a station. In full-duplex mode, a station can simultaneously transmit and receive independent data streams for potential data throughput of 32 Mbps.
Other Features 1-3 ■ Promiscuous mode support for the Windows 95 and Windows NT NDIS miniport drivers. In promiscuous mode, the NIC receives and forwards all network packets that arrive, regardless of the node to which they are addressed. Applications such as Microsoft Systems Management Server require the driver to be in promiscuous mode while they run. Promiscuous mode is automatically enabled and controlled by applications that require this feature. No user control is necessary.
