  • Automatic communication protocol detection system and method for network systems
    Patent number: 6072803
    Abstract: A communication protocol detection system for enabling a network system to detect and interface one or more network devices each operating according to at least one of a plurality of different communication protocols. In one embodiment, a network interface card (NIC) is capable of operating according to one of two different communication protocols, such as the 10Base-T and 100Base-TX Ethernet Standards. The NIC includes two corresponding transceivers, where the transceivers are interfaced to a network connector for interfacing an external network device. Control logic initially enables the 10Base-T transceiver to determine if link pulses are detected. If link pulses are detected, the 100Base-T transceiver is enabled to determine if it detects the link pulses. If so, the 100Base-T transceiver is used to establish communications, and if not, the 10Base-T transceiver is used.
    Type: Grant
