13.8. Model 1 Configuration Guidelines for Gigabit Ethernet

Transmission System Model 1 of the Gigabit Ethernet standard provides simplified configuration guidelines. The goal of the configuration guidelines is to ensure that the timing requirements for Gigabit Ethernet are met so that the medium access control (MAC) protocol will function correctly. The rules for half-duplex Gigabit Ethernet configuration are:

• The system is limited to a single repeater.

• Segment lengths are limited to the lesser of 316 meters (1,036.7 feet) or the maximum transmission distance of the segment media type.
