This shows the LED Output Functions for the LED Drivers when 74LS259s are used. The top table refers to the bank of 4 74LS259s latched with
and the lower table refers to the bank of 4 74LS259s latched with
74LS259s then drive the LINK LEDs.

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 at-
tached to this RIC2A. This signal should be connected to the data inputs of the chosen pair of
74LS259 latches.
Provides status information indicating if one of this RIC2A's ports is receiving a 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 RIC2A 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 RIC2A's ports is receiving data of inverse polar-
ity. 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 lower byte latches, that is the 74LS259s which display infor-
mation concerning ports 1 to 7.
This signal is the latch enable for the upper byte latches, that is the 74LS259s which display infor-
mation concerning ports 8 to 13.
