– If you use W5100S-EVB-Pico, you can skip ‘1. Loopback is a testing procedure in telecommunications in which a test signal is sent from a service provider’s central office (CO) to the customer premises and is returned or echoed by the customer premises equipment (CPE) back to the service provider.
