TS4000 Radio Modem User’s Manual AirNet Packet Protocol 52
A chain repeater topology is one where the messages are passed down a chain of
repeaters. This is typical for systems that operate along a road, river or railroad
track.
For the specific configurations defined in this example, the base and each repeater
must hear only the next repeater in the chain. For example: Repeater B hears only
Repeater A and C but not the Base and Repeater D.
