Media Converter Port in Full-Duplex Network

In a full-duplex network, maximum cable lengths are determined by the cables used. See page 10 for cable specifications.

NOTE: The 512-Bit Rule described below does NOT apply in a full-duplex network.

Media Converter Port in Half-Duplex Network

The 512-Bit Rule applies separately to each collision domain.

USING THE 512-BIT RULE

In a half-duplex network, maximum cable lengths are determined by the round trip delay limitations of each Fast Ethernetcollision domain. (Switches and routers divide the network into separate Ethernet™ collision domains.) The 512-Bit Rule determines maximum distances by calculating the collision domain round-trip delay in bit-times.
