标题: Understanding Relay Functional Testing: Ensuring Reliable Communication Systems In modern communication networks, ensuring the seamless flow of information is critical. One essential component that plays a vital role in maintaining network integrity is the relay device. A relay acts as an intermediary, receiving signals, amplifying or processing them, and then forwarding them to the next node in the network. To guarantee that relays operate effectively and reliably, engineers perform a process known as Relay Functional Testing. This type of testing is fundamental in telecommunications, networking, and other systems where signal transmission integrity is crucial.
