W89C982AF General Description
The Integrated Multiple Port Repeater II (IMPR II) implements the repeater functions specified by section 9 of the IEEE 802.3 standard and twisted pair line transceiver functions conforming to the 10BASE-T standard. The IMPR II provides eight Twisted Pair (TP) Line Transceiver Ports and an Attachment Unit Interface (AUI) port. Each Twisted Pair (TP) Line Transceiver Port can connect to an Ethernet segment through a twisted pair line. The AUI port can connect to a thick Ethernet segment by means of a 50-meter AUI cable. The IMPR II provides an AUI/TP port status direct report function, which uses the ten port status pins and two select pins to indicate collisions, port link/activity, partition, polarity, and network utilization. The inter-IMPR II interface includes signals for connecting more than one IMPR II to increase the total number of hub ports. The manageable functions of the repeater and twisted pair line transceiver in the IMPR II can be accessed through a serial interface.
