Advanced Micro Devices AM79C985

the Am79C987 Hardware Implemented Management Information Base (HIMIB™) device for building a basic managed multiport repeater s Full software backwards compatibility with existing hub designs using Integrated Multiport Repeater Plus (IMR+™)/HIMIB devices s Network management and optional feature accessibility through a dedicated serial management port s Four integral 10BASE-T transceivers with onchip filtering eliminating the need for external filter modules on the 10BASE-T transmit-data (TXD) and receive-data (RXD) lines s One Reversible Attachment Unit Interface (RAUI™) port used either as a... The device integrates the repeater functions specified in Section 9 of the IEEE 802.3 standard and Twisted Pair Transceiver functions complying with the 10BASE-T standard. The eIMR+ device provides four Twisted Pair (TP) ports and one reversible AUI (RAUI) port for direct connection to a MAC.
