The technology of the tone circuit and the decode of Diplex-Tone Multi-Frequence to realize some functions of the 121 segregate mailbox is described. The system possesses a simple realizable circuit with low cost and high reliability. It can function such as the 121 tone manufacture and auto-response when working with the relative software or alone. It can also work normally with the batteries as the power. Hence it is suitable for the primary meteorological observatory as the 121 backup system.
