following the guidelines listed for each to form a link. For mixed topologies
(series and parallel) the maximum number of repeaters in series between any
two nodes is twenty.
Figure C.7 Repeaters In A Combination Of Series And Parallel

For example: if a message travels from device 1 or 2 to device 4, it travels
through 5 repeaters.
