The basic Integrated Multiport Repeater (bIMRTM) chip is a VLSI circuit that provides a system-level solution to designing a compliant 802.3 repeater incorporating 10BASE-T transceivers. The device integrates the Repeater functions specified by Section 9 of the IEEE 802.3 standard and twisted-pair Transceiver functions complying to the 10BASE-T standard. The Am79C982-4 provides four and the Am79C982-8 provides eight integral twisted-pair medium attachment units (MAUs), and an attachment unit interface (AUI) port in an 84-pin plastic leaded chip carrier (PLCC). A network based on the 10BASE-T standard uses unshielded twisted-pair cables, therefore providing an economical solution to networking by allowing the use
