FUNCTIONAL DESCRIPTION
The Integrated Multiple Port Repeater II implements the functions stipulated in the IEEE repeater
specifications, the functions specified by 10BASE-T standards, and functions for network
management. It provides an Inter-IMPR II interface to allow implementation of a repeater set with
more network ports. The block functions of the IMPR II are described below.
AUI Interface and Twisted Pair Line Transceiver
The AUI provides an interface for an external Medium Attached Unit (MAU) connected to the IMPR II.
The IMPR II can be used to connect a 10BASE2 or 10BASE5 Ethernet to a 10BASE-T Ethernet via a
coaxial transceiver. The Twisted Pair Line Transceiver provides the interface used to connect IEEE
802.3 LAN stations (Data Terminal Equipment, or DTEs) into Ethernet networks constructed from
twisted pair media. The Twisted Pair Line Transceiver also contains a link test function and
autopolarity reversal function for wiring detection.
Link Test Function
The link test function of the TP port is used to check whether the TP port is linked to an active TP
port. The TP port will enter link fail state if it does not receive any packets or link test pulses for more
than 60 mS, until it receives either six consecutive link pulses or a packet. When the TP port is in link
