PROGRAMMABLE DELAY, TRANSPARENT SWITCHING MULTI-PORT INTERFACE LINE CARD

摘要

A network interface card and system incorporating the interface card with hardware link failure detect circuitry and operating system compliant driver and GUI management software and system operator selectable delay, to provide soft fail-over transfer from the primary to a secondary network link port without data loss. The systems comprising the multi-port interface card according to the present invention provide a single network and redundant paths with optional conversion to different data medium, e.g. between fiber optic and twisted pair, and also comprises multi-network configurations connecting common equipment having the multi-port interface card according to the present invention therein.
