10 0 Switching Characteristics
TRANSMIT TIMING 10BASE-T PORTS
Receive activity propagation start up and end delays for ports in 10BASE-T mode
Note ACKI assumed high
Note 1 Clock not drawn to scale In this measurement falling edge of the clock for even ports and rising edge of the clock for odd ports are considered
COLLISION TIMING AUI PORTS
Collision activity propagation start up and end delays for ports in non 10BASE-T mode
TRANSMIT COLLISION TIMING
Note 1 TX collision extension has already been performed and no other port is driving ANYXN
Note 2 Includes TW2
