FIG. 7a represents the signal S1 delivered by the detection means 120 of the control contactor means 10 of the telephone device 2. The signal S1 goes from the low state to the high state when the detection means detect an electrical conduction between the mobile means and the thimble
crits with reference to Figure 2. This transition from the low state
in the high state corresponds to the actuation of the contactor means
10. The first actuation 11 triggers the execution

200 kilo-ohms, which gives a pulse duration
about 6.6 seconds.

FIG. 7c represents the signal S3 collected at the output
508. Signal 53 is the reverse of signal S2.

FIG. 7a represents the signal S4 collected by the output
608 ae la, flip-flop D. At output 608, signal S4 goes from
the low state to the high state in the presence of the rising edge of the
signal S2 applied to the clock input 606 of the flip-flop 600.

Thus, the relays R1 and R2 are active and switch the
hooks on the telephone set to put it into service.

The signal collected at output 610, signal reverse of the signal
S4, is applied to data entry 604, which
result of passing the signal S4 from the high state to the state
low at the next rising edge of S2.

Figure 7e shows the signal 55 collected at the output
526 of the monostable 520. In the presence of the signal S1, the signal
Sg goes from the low state to the high state. Pulse duration
collected in 526 is determined by the RT3-C3 network. By
example C3 has a capacity of 4.7 microfarads and RT3 has a
resistance of 30 kilo-ohms, which allows to obtain a
0.14 second pulse duration.

FIG. 7f represents the signal S6 collected at the output 566 of the monostable 560. The signal 56 passes from the low state to the high state in the presence of the rising edge of S3 collected at the input 562 of the monostable 560. The duration of the signal pulse S6 is of the order of 1 second when RTlo has a value of 105 ohms and C5 a capacity of 10 microfarads.

The signal S6 triggers the relay R3 controlling the amplification of the voice-activated telephone set.

FIG. 8a represents the ringing signal S7 12 coming from the ringing means 406 of the telephone set 400 and consisting of a train of pulses of duration 1.7 seconds spaced by 3.3 seconds. The signal S7 acts on the trigger input 544 of the monostable 540.

FIG. 8b represents the signal Sg collected at the output 546 of the monostable 540. In the presence of the rising edge of the signal
S7 at trigger input 544, the signal Sg goes from the low state to the high state. The duration of the signal Sg is determined by the value of RTg and C4. For example, C4 has a capacity of 68 microfarads and RTg has a value of 91 kilo-ohms, which makes it possible to obtain a pulse duration of the order of 6 seconds.

FIG. 8c represents the signal-S1 delivered by the detection means 120 of the control contactor means 10 of the telephone device 2.

The signal S1 passes from the low state to the high state when the user actuates the control contactor means 10. The first actuation triggers off-hook in the presence of a ring and allows the establishment of telephone communication 20. The second actuation initiates hang up when the telephone call is completed.

FIG. 8d represents the signal S2 collected at the output 506 of the monostable 500. The duration of the signal S2 is determined by the values RT1 C1 and RT8.

FIG. 8e represents the signal S3 collected at the output 508 of the monostable 500. S3 is the inverse of S2.

FIG. 8f represents the signal S4 collected at the output 608 of the flip-flop D 600. At output 608, the signal S4 goes from the low state to the high state in the presence of the rising edge of the signal S2 applied to the clock input 606 of flip-flop 600. Thus, the relays R1 and R2 are active and switch the hooks of the telephone set to put it into service.

The signal collected at the output 610, inverse signal of S4, is applied to the data input 604 which results in passing the signal S4 to the next rising edge of
S2 from high to low.

FIG. 8g represents the signal Ss collected at the output 526 of the monostable 520. This signal S5 controls the adjustment of the amplification control of the telephone set via the relay R4 and the switch I2.

FIG. 8h represents the signal S6 collected at the output 566 of the monostable 560. The signal S6 switches the amplified listening of the telephone line via the relay R3 of the switch I2.

It will be understood that the invention is not limited to the embodiments which have just been described by way of examples, but incorporates all the variants thereof.

Thus, the telephone device 2 can be provided with an automatic on-hook function in the presence of the busy tone signal of the called telephone set.

The presence of the busy signal of the called telephone set will be detected by analyzing the frequency and cadence of the line seizure signal.

Finally, the adapter means 300 can be incorporated into the voice-controlled telephone set 400.
