SUBSTANCE: invention can detect data signals among many possible data sources in context of network neighborhood provided with devices which use auto-negotiation during period of auto-negotiation. Scheme actuates switching of input port of network device alternatively between various possible data sources. If interval signal is detected indicating that coming period of auto-negotiation wasn't detected, then switching action ceases and input port is kept connected till data transmission channel is detected. After that, device reverts to status of switching. If interval signal is detected indicating that coming period of auto-negotiation was detected, switching action ceases for period equal to or exceeding period of auto-negotiation. After that if interval signal is detected, than input port is kept connected till data transmission channel is detected.
