relay systems
Sequential transmission networks
Relay systems are arrangements where something is passed along a chain of stations, people, or devices.
The term applies to communication networks where signals are received and retransmitted, to postal routes using fresh horses at intervals, or to electrical circuits where one switch activates another.
The emergency relay system ensured messages reached remote outposts within hours.
