IEEE 802.3 Four
Repeater Rule
No more than four repeaters may be linked to connect five segments and no other
attachments may be on the linking segments. If attachments are present on the
repeater coax link segments, then no more than two repeaters linking three
segments may be configured. These limitations are set to keep propagation delay
packet jitter, and signal attenuation to within acceptable standards.
