It This device contains five full-duplex 10BASE-T/100BASE-TX Fast combines all of the functions of a high-speed switch system Ethernet transceivers, each of which performs all of the physical including packet buffer, PHY transceivers, media access layer interface functions for 10BASE-T Ethernet on Category 3, 4, controllers, address management, and a nonblocking switch or 5 Unshielded Twisted-Pair (UTP) cable and 100BASE-TX Fast fabricinto a single 0.18 CMOS device. It complies with the Ethernet on Category 5 UTP cable. IEEE 802.3, 802.3u, and 802.3x specifications, including the MAC E2PROM interfaces provide easy programming of the 802.1p control PAUSE frame and auto-negotiation subsections, providing QoS queues. This allows switch traffic to be given different compatibility with all industry-standard Ethernet and Fast Ethernet classes of priority or service, for example, voice traffic for IP phone devices. applications, video traffic for multimedia applications, or data traffic for e-mail applications.
