ADDITIONAL NOTES: By cascading Repeaters and/or Multiport-Repeaters very large and "robust" networks can be formed (several thousand nodes) with proper bias/termination. Isolation helps prevents large network "melt-down." Networks with "Home Runs" and "Daisy-Chains" can be mixed for maximum flexibility. Extended distance and flexible control.
