Embodiment 1

The described telephone set of present embodiment is seen shown in Figure 1 with the circuit theory diagrams of the transponder (abbreviation transponder) of meeting sb. at the airport.

Telephone set is made up of triode T1, voltage-stabiliser tube Z1, LED, control switch K, resistance R a, Rb, R1, R2, capacitor C 1 and microphone device U1 with the transponder circuit of meeting sb. at the airport.Triode T1 and resistance constitute switching circuit, resistance R a, Rb constitute the base loop of triode T1, K switch is connected in the base loop, in the output loop of triode T1, be in series with voltage-stabiliser tube Z1 and resistance R 2, in the output loop of triode T1, also be in series with LED and resistance R 1; Microphone device U1 is connected in parallel on the series resistance R2 of voltage-stabiliser tube Z1, and capacitor C 1 is connected on the output of microphone device U1.

The A1 of circuit, B1 end is the end of incoming cables of telephone wire, and when ringing telephone stations, the callee clicks " reservation " key, at this moment, the control switch K closure in the telephone set, triode T conducting, the LED conducting is luminous, and the indication circuit is connected; Because " reservation " state is disconnected the words load, then telephone wire power supply (48V) makes voltage-stabiliser tube Z1 conducting by triode T1, give microphone device U1 power supply, make its work, the voice of microphone device U1 output are or/and music signal, output on the telephone line by capacitor C 1, make the calling subscriber know that the callee is just busy, please its wait.

After the callee normally received calls, telephone line voltage reduced, and this moment, voltage-stabiliser tube Z1 ended, and microphone device U1 does not work, thereby telephone set can carry out normal talking.

When triode T1 conducting, LED also conducting is luminous, and the expression telephone set is in the user mode of meeting sb. at the airport, or the expression telephone set is in the wait reserved state.
