ACTivity on Port N This is a bidirectional signal The LERIC asserts this signal when data or
collision information is received from one of its network segments
The LERIC senses this signal when this LERIC or another LERIC in a multi-LERIC system is
receiving data or collision information
Activity on ANY Port EXcluding Port N This is a bidirectional signal The LERIC asserts this signal
when a transmit collision is experienced or multiple ports have active collisions on their network
segments
The LERIC senses this signal when this LERIC or other LERICs in a multi-LERIC system are
experiencing transmit collisions or multiple ports have active collisions on their network segments

ACTivity on Port N Drive The LERIC asserts this signal when data or collision information is
received from one of its network segments
ACTivity on Port N Sense The LERIC senses this signal when this LERIC or another LERIC in a
multi-LERIC system is receiving data or collision information
Activity on ANY Port EXcluding Port N Drive The LERIC asserts this signal when a transmit
collision is experienced or multiple ports have active collisions on their network segments
Activity on ANY Port EXcluding Port N Sense The LERIC senses this signal when this LERIC or
other LERICs in a multi-LERIC system are experiencing transmit collisions or multiple ports have
active collisions on their network segments
PacKet ENable This signal acts as an active high enable for an external bus transceiver (if
required) for the IRE IRC IRD and COLN signals When high the bus transceiver should be
transmitting on to the bus i e this LERIC is driving the IRD IRE IRC and COLN bus lines
When low the bus transceiver should receive from the bus
