Provides status information concerning the Link Integrity status of 10BASE-T segments This signal should be
connected to the data inputs of the chosen pair of 74LS259 latches
Provides status information indicating if there is a collision occurring on one of the segments attached to this LERIC
This signal should be connected to the data inputs of the chosen pair of 74LS259 latches
Provides status information indicating if one of this LERIC’s ports is receiving data or a collision packet from its
segment This signal should be connected to the data inputs of the chosen pair of 74LS259 latches
Provides status information indicating that the LERIC has experienced a jabber protect condition Additionally it
denotes which of its ports are partitioned This signal should be connected to the data inputs of the chosen pair of
74LS259 latches
Provides status information indicating if one of this LERIC’s ports is receiving data of inverse polarity This status
output is only valid if the port is configured to use its internal 10BASE-T transceiver The signal should be connected to
the data inputs of the chosen pair of 74LS259 latches
These signals provide the repeater port address corresponding to the data available on D(4 0)
This signal is the latch enable for the 74LS259 latches
