Description

TELEPHONE HEADSET WITHOUT OFF-HOOK HANDSET REQUIREMENT}

In an environment that requires heavy use of the hand, the handset can often be an obstacle.

For example, secretaries, travel agents, and people who sell on the phone often have to take notes or perform other tasks while answering the phone.

As you can see, the people in these occupations are much less efficient while holding the phone.

To overcome this drawback, a speakerphone has been developed so that the user does not have to pick up the handset during a call.

However, although the speakerphone frees the user's hands, the user may have experienced that private freedom is not guaranteed when using the speakerphone.

For example, when a user receives a call on a speakerphone in an office, anyone in the vicinity can hear all the conversations between the user and the call party.

To overcome these shortcomings, a headset for a telephone has been developed in which a user can freely use his or her hand while making a call without picking up the handset, and at the same time, a user's conversation is not exposed to others.

1, an arrangement of a conventional telephone handset and a headset is shown.

The telephone (such as the desktop type) 10 is connected to the communication line 12 through the telephone line 14 and the telephone jack 16.

The earpiece 18 is supported by the telephone 10 by hanging on the hanging portion 20 of the telephone body.

The handset 18 is connected to the telephone 10 via the handset line 22, the connection device 24, and the connection line 26.

The headset 28 is operatively connected to the telephone 10 via the headset wire 30, the interface device 24 and the interface wire 26.

This arrangement allows the user to answer the call via the handset 18 or the headset 28.

However, a significant disadvantage of this arrangement is that in order to answer the call with the headset 28, the handset 18 needs to be detached from the cradle portion 20 (the part where the handset is placed in the telephone) (ie, the handset). For example).

Another significant drawback is that when making a call with headset 28, the handset 18 must be operated directly by releasing the handset 18 from the portion 20 where the handset is raised.

A further disadvantage of the above arrangement is that there is a telephone in the aisle extended to hear between the communication line 12 and the headset 28.

As is well known in the art, the voice signal degrades as the voice signal passes through various communication elements.

This degraded signal results in poor sound quality.

Accordingly, there is a continuing need for a telephone headset connection unit that enables connection between a regular telephone and a telephone headset without lifting a handset or using a telephone keypad.

However, the Applicant knows that there are currently no known techniques to supplement the aforementioned disadvantages.

More specifically, the following description is the known art with the largest relationship to the present application.

In addition, the connection device is located in the audible passage between the voice recognition device and the telephone communication line, and the connection device switches between the contact state and the non-contact state in response to the user's manual operation of the connection device.

The connecting device enables communication between the headphone and the telephone line when the connecting device is in the contact state, and inhibits the communication when the contact device is not in contact.

The above and other advantages of the present invention described above will be more clearly understood with reference to the following description of the drawings.

2, the headset 40 and headphone interface unit 42 of the present invention can be seen.

The headset 40 includes an on / off button 41, a microphone 44, and a speaker 46.

The headset 40 is operatively connected to the headphone interface 42 via a cord 48, which has a connector mated with the stereo jack 50 of the interface unit 42.

The stereo jack 50 is connected to three conductors connected to the voice network circuit 52.

The first conductor 54 is connected to the ground of the headset interface unit 42.

The second conductor 56 connects the microphone 44 in the headset 40 with the voice network circuit 52.

The third conductor 58 connects the speaker 46 in the headset 40 to the voice network circuit 52.

The volume control circuit 60 is connected to the voice network circuit 52 to allow the user to adjust the volume of sound heard through the speaker 46.

The mute switch 62 is also connected to the voice network circuit 52 so that the user can temporarily stop the signal from the microphone 44 so that the caller can not hear the user and the third party.

As is well known in the art, the voice network circuit 52 is also equipped with a microprocessor, amplifier, and other types of telephone processing elements.

The mute and volume control circuit locations in the headset interface unit 42 are within the scope of the present invention.

In addition, the position of the on-off button in the headset 40 is included in the scope of the present invention.

The off-hook element 64 is connected to the I / O device 66 via an internal line 68.

I / O device 66 is a telephone jack for conversation.

First line 70 connects I / O device 66 with three-way coupler 72.

The second line 74 connects the three-way coupler 72 to the conversational phone 76 with the handset 78 located in the cradle area 79.

By this arrangement, the three-way coupler 72 connects the telephone connected to the telephone line 82 with the telephone jack 80 and the headset interface unit 42 and the telephone 76.

During normal use, the user communicates an incoming call through the handset 78 by picking up the handset 78 from the cradle portion 79 on the telephone 76.

During hand-free use, the user puts the headset 40 on his head and closes the switch 65 to the off-hook position by pressing the button 41 on the headphone 40 with the off-hook element 64.

In this way, an audible pathway is established between the speaker 46 of the headset 40 and the microphone 44 and the communication line 82.

The user can then communicate with the caller through the headphones 40 while doing other work with the hand.

At the end of the call, the user operates the button 41 to press the switch 65 to cause the off-hook element to go on-hook, thereby removing the audible path between the headset 40 and the communication line 82.

The role of the switch 65 in the headset 40 area has been considered within the scope of the present invention, showing that the switch 65 is set in the headset interface unit 42.

A keypad (not shown) is provided to the headset interface unit 42 to allow the user to make a call through the headset 40.

The user presses the button 41 to bring the off-hook element 64 off-hook to make a call through the audible passage between the headset 40 and the communication line 82.

The user then calls the calling number with the keypad (not shown).

If there is no keypad, lift the handset 78 from the cradle 79 and press button 41 to activate it.

Then, the number to be dialed on the telephone keypad 78a is called.

When the telephone is connected, the handset 78 is put back on the cradle 79 and the call continues through the headset 40.

Separately, the user operates both the button 41 and the speaker button 79a and enters a number to be dialed through the telephone keypad 78a.

When the phone is connected, the user operates the speaker button 79a again to continue the call through the headset 40.

3, there is shown a wireless headset 100 and a wireless headset interface unit 102 of the present invention.

The wireless headset 100 includes an on / off button 104, a microphone 105, a speaker 108, and a transceiver 110.

The wireless headset 100 is in remote communication with the wireless headset interface unit 102 via a radio wave signal.

In particular, the radio wave signal 112 transmitted by the transceiver 110 is received by the transmit / receive antenna 114 of the wireless headset interface unit 102 and by the transmit / receive antenna 114 of the wireless headset interface unit 102. The received radio wave signal 112 is received by the transceiver 110 of the wireless headset 100.

Apart from this, an on-off button 104 may be located on the wireless headset interface unit 102.

A power source 122, such as a dry cell, is located in the wireless headset interface unit 102 to provide power to the unit 102.

The transmit / receive antenna 114 is connected to the electrical transmitter circuit 118 and the receiver circuit 120.

The transmitter circuit 118 is electrically connected to the voice network circuit 124 through the audio output line 126.

The receiver circuit 120 is electrically connected to the voice network circuit 124 through the audio input line 128.

The receiver circuit 120 is also electrically connected through the data detector 130 and the data line 132.

The off-hook element 134 is connected to the data detector 130 through the control line 136.

The off-hook element 134 is also connected to the voice network circuit 124 via the internal line 138.

The I / O device 140, such as a general telephone jack, is connected through the off-hook element 134 and the inner line 142.

The first wire 70 connects the I / O device 140 with the three-way coupler 72, like the wired headset and headset interface unit of FIG. 1.

The second line 74 connects the three-way coupler 72 with a conventional telephone 76 where the handset 78 is placed in the cradle portion 79.

In this arrangement, the three-way coupler 72 connects the telephone 76 and the wireless headset interface unit 102 to the telephone jack 82 and then to the communication line 82.

During normal use, a user picks up an incoming call from the cradle portion 79 on the telephone 76 and communicates through the telephone 78.

During hand-free use, the user wears the wireless headset 100 on his head and activates the on / off button 104 to answer the call.

When operated, wireless headset 100 transmits a call " enable " signal through transceiver 110.

The call "enabled" signal is received by the receiver circuit 120 via the antenna 114.

The receiver circuit 120 generates a data signal via the data line 132 in response to a call "enabled" signal response.

When the data detector 130 detects a data signal at the data line 132, the data detector 130 transmits a control signal through the control line 136.

This control signal causes the off-hook element 134 to go off-hook, thereby providing an audio signal path between the communication line 82 and the voice network circuit 124.

After the audio signal path is established, the user may receive an audio signal coming through the wireless headset 100 and transmit the audio signal to the outside.

When receiving an audio signal coming in through the wireless headset 100, the input audio signal is transmitted from the communication line 82 to the voice network circuit 124 via the off-hook element 134.

As can be seen from this technique, the voice network circuit 124 can modulate the required input audio signal through an amplifying and filtering device.

The modulated input audio signal is transmitted to the transmitter 118 via the audio output line 126.

The transmitter 118 converts the audio signal into an audio wave signal and transmits the signal through the antenna 114.

The transceiver 110 receives the radio wave signal, converts the radio wave signal into an audio signal, and sends it to the speaker 108.

When transmitting an output audio signal through the wireless headset 100, the microphone 106 generates audio signals that are converted by the transceiver 110 into radio wave signals.

The radio wave signal from the transceiver 110 is received by the receiver 120 via the antenna 114.

The receiver 120 converts a radio signal into an audio signal, and the audio signal is transmitted to the voice network circuit 124 through the audio input line 128.

As can be seen from this technique, the voice network circuit 124 can modulate the required audio input signal through the amplifying and filtering devices.

The modulated audio signal is transmitted to the communication line 82 through the off-hook element 134, the input / output terminal 140, the three-way coupler 72, and the telephone jack 80.

When the call is complete, the user must turn off the wireless headset by pressing the on / off button.

In response to the off state, the wireless headset 100 is communicated as a "disabled" signal through the transceiver 110.

This " disabled " signal is received by the receiving device 120 via the antenna 114.

In response to the reception of the " disabled " signal, the reception device 120 generates a data signal by the data line 132.

When the data signal is detected at the data line 132, the data detector 130 transmits a control signal to the control line 136.

The control signal causes the off-hook device 134 to be on hook.

For this reason, the audio signal path between the communication line 82 and the voice network circuit 124 is disconnected.

When the keypad is connected to the headset connector 102, the user can make a call through the wireless headset 100.

To make a call, the user presses the on-off button 104 to make it off-hook.

This creates an audible path between the wireless headset 100 and the communication line 82.

The user then dials through the keypad.

If the keypad is not ready, the user must press the on / off button 104 and remove the handset 78 from the cradle portion 79.

After the call is connected, the user can return the handset 78 to the cradle 79 and continue the call through the wireless headset 100.

Alternatively, the user may press both on and off button 104 and speaker button 79a and place a call through telephone keypad 78a.

After the phone is connected, the user can continue to talk through the wireless headset 100 by pressing the speaker button 79a.

4 shows a voice recognition headset 150 and a voice recognition headset connection device 152 that are currently designed.

The voice recognition headset 150 includes a microphone 154, an on / off button 155, and a speaker 156.

The on-off button 155 should be placed on the voice recognition connection terminal 152.

The voice recognition headset 150 is effectively connected to the voice recognition headset connector 152 through a cord having a connector coupled to the stereo jack 16 in the voice recognition headset connector 152.

The stereo jack has a structure in which three conductors are connected to three voice network circuits 162.

The first conductor 164 is connected to the ground of the voice recognition headset connector 152.

The second conductor 166 is connected to the microphone 154 and the voice network circuit 162 in the voice recognition headset 150, and the third conductor 168 is connected to the speaker 156 and the voice network in the voice recognition headset 150. Is connected to the circuit 162.

One language recognition and integration module 170 is connected to an audio input line 172 and a dual tone-multi-frequency line 174.

The language recognition and integration module 170 detects simple voice commands from the voice recognition headset connection terminal 152 and the user.

Simple commands include the numbers "0" to "9", and the commands "to" and "end".

The language recognition and integration module 170 must recognize the "enabled" and "disabled" instructions.

It should be appreciated that the language recognition and integration module 170 also communicates to store the stored numbers and numbers in the memory.

Due to such equipment, the user can quickly call a phone number to the language recognition and integration module 170 by calling out the name stored in the memory.

The speech recognition capacity allowed by the language recognition and integration module 170 receives the voice telephone number, and a signal is transmitted to the DTMF to reproduce the voice telephone number.

One off-hook device 176 is electrically connected to the language recognition and integration module 170 through the control line 178.

The off-hook device is also electrically connected to the voice network circuit 162 through the internal line 180 therein.

The I / O terminal is also connected to the off-hook terminal 176 through the inner wire 184 like a normal jack.

1 shows a wired headset and a connector.

The first cord 70 is connected to the three-way coupler structure 72 at the I / O terminal 182.

The connection of the second cord 74 places the handset 78 of the telephone 76 in the cradle portion 79 at the three-way coupler 72.

By this equipment, the three-way coupler 72 is connected to the telephone 76 and the voice recognition headset terminal 152 is connected to the telephone jack 80 to connect the telephone to the communication line 82.

During normal operation, the user can receive and communicate with the handset 78 by removing the handset 78 from the cradle portion 79 on the phone 76.

The user sends a call by removing the handset 78 from the cradle portion 79 of the telephone 76 and pressing the keypad 78a number.

On the other hand, the transmission connection may be a user communicates through the handset 78.

During the hands-free operation, the user can receive an incoming call by placing the headset on the head in the voice recognition position and pressing the on / off button as shown in FIG. 2.

If the language recognition and integration module 170 recognizes the "enabled" command, the user must adjust the speech recognition headset 150 by storing the word "enabled".

The word " enabled " represented by the audio signal is generated by the microphone 154, which is transmitted via the code 158 to the voice network circuit 162.

As can be seen from this technique, the voice network circuit 62 can modulate the required audio input signal through the amplifying and filtering devices.

The word " enabled " represented by the modulated audio signal is transmitted from the voice network circuit 162 to the language recognition and integration module 170 via the audio input line 172.

For the reception of the modulated audio signal, the language recognition and integration module 170 transmits, by the control line 178, the control signal to be located at the off-hook terminal 176 in the off-hook position.

When the audio signal path of the off-hook terminal 176 in the off-hook position is set between the communication line 82 and the voice recognition headset 150, the audio signal path is the telephone jack 80, the three-way coupler 72, i / o terminal 182, off-hook terminal 176, voice network circuit 162, and voice recognition headset 150 is extended to adjust.

By such equipment, it is possible to receive an incoming call by the voice recognition headset 150 through the voice recognition headset connector 152.

During the " handfree " operation, the user may set the voice recognition headset 150, press the on / off button 155 to place it in a call position, and call the number to be transmitted to make a call.

The user may end the call by saying the word "end", and if the language recognition and integration module 170 recognizes "enable", the user must adjust the voice recognition headset 150 to place it in the call position. .

The words "available" and "dial" are used to make a call to the telephone number.

As previously mentioned, the word "enabled" is set up as an audio path between voice-activated headset 150 and communication line 82.

The word " dial ", which is a word represented by an audio signal, is generated by the microphone 154, which is transmitted to the voice network circuit 162 via the code 158.

As can be seen from this technique, the voice network circuit 162 can modulate the required audio input signal through the amplifying and filtering devices.

The modulated "dial" signal is transmitted from the voice network circuit 162 to the language recognition and integration module 170 via the audio input line 172.

In response to receiving a modulated " dial " signal, the language recognition and integration module 170 enables DTMF line 174.

As can be seen from this technique, the language recognition and integration module 170 also needs to set the state of the internal bus and registers to "and / or".

The number of voice strings represented by the audio signal is generated by the microphone 154, which is transmitted to the voice network circuit 162 via the code 158.

The voice network circuit modulates an input audio signal, and the modulated audio signal is transmitted to the language recognition and integration module 170 through the audio input line 172.

In response to receiving the modulated " number " signal, the language recognition and integration module 170 transmits the number of DTMF signal strings and the number of indications to the voice network circuit 162 via the DTMF line.

Voice network circuit 162 then transmits the DTMF signal to communication line 82 through off-hook terminal 176, I / O element 182, three-way coupler, telephone jack 80.

The audio signal representation word "termination" is made by microphone 154, which is transmitted to voice network circuitry 162 via code 158.

This voice network circuit 162 modulates the end " signal ", and the modulated " end " signal is transmitted to the language recognition and integration module via the audio input line 172.

In response to receiving a modulated " terminated " signal, the language recognition and integration module disables DTMF until the response of the next " dial " signal.

When the transmit / receive call is completed, the user must press the on-off button 155 to disconnect the voice recognition headset 150 from the communication line 150.

If the language recognition and integration module 170 recognizes the "impossible" command, the user should say the word "disabled" to disconnect the voice recognition headset 150.

The "disabled" represented by the audio signal is generated by the microphone 154, which is transmitted to the voice network circuit 162 via the code 158.

This voice network circuit 162 modulates the received " disabled " signal and the modulated " disabled " signal is transmitted via the audio input line 172 to the language recognition and integration module.

In response to receiving a modulated " disabled " signal, the language recognition and integration module 170 is sent to set the off-on-hook terminal 176 to a control signal by the control line 78 in the off-on-hook position.

When the off-on-hook terminal 176 is in the on-hook position, the audio signal path between the communication line 82 and the voice recognition headset 150 is broken.

5 shows a voice recognition wireless headset 200 and a voice recognition wireless headset interface unit 202 that are currently in design.

The headset 200 includes an on / off button 504, a microphone 206, a speaker 208, and a transceiver 210.

The on-off button 204 should be connected to the wireless headset interface unit 202.

The headset 20 is communicated away from the wireless headset interface unit 202 via a radio wave signal.

In particular, the radio wave signal 212 is received at the transmit / receive antenna 214 in the wireless headset interface unit 202 and transmitted to the transceiver 210 and the radio signal 216 is transmitted to the transceiver 210 in the wireless headset 200. And is transmitted to the received transceiver antenna 214.

A power source 222, such as a bat, is located in the wireless headset interface unit 202 to supply power to the wireless headset interface unit 202.

The transceiver antenna 214 is electrically connected to the transmitter 218 and the receiver 220.

The transmitter 218 is electrically connected to the voice network circuit 224 through the audio output line 223.

The receiver 220 is electrically connected to the language recognition and integration module 228 through the audio input line 230.

The language recognition and integration module 228 of the wireless headset interface unit 202 detects a simple voice command spoken by the user.

This simple command includes the numbers "0" to "9" and the commands "dial" and "end".

The language recognition and integration module 228 should also be aware of "possible" and "impossible".

The language recognition and integration module 228 must also allow the user to communicate with numbers stored in memory.

Such equipment allows the user to quickly dial frequently used phone numbers stored in memory with the language recognition and integration module 228.

The speech recognition capabilities allowed in the language recognition and integration modules should be allowed to receive speakerphone numbers and transmit DTMF signals to reproduce the speakerphone numbers.

The language recognition and integration module 228 is connected to the voice network circuit 224 through the DTMF line 238 and the bypass line 240.

The off-hook terminal 232 is electrically connected to the language recognition and integration module 228 via the control line 234.

The on-hook terminal 232 is also electrically connected to the voice network circuit 224 via the inner wire 236.

I / O element 242 is also electrically connected to voice network circuitry 224 via an internal line 236 as a normal jack.

5 shows a wired headset and a headset interface unit.

In the normal operation period, the user can remove the handset 78 from the cradle portion 79 of the telephone 76 to receive an incoming call and make a call through the handset 78.

The user removes the handset 78 from the cradle portion 79 of the telephone 76 and transmits a transmission call by turning a number to be transmitted by the keypad (not shown).

At this time, the transmission connection can be communicated by the user through the handset 78.

In the hand-free operation period, as shown in FIG. 3, the user may adjust the headset 200 mounted on the head, and receive an incoming call by pressing the on / off button as shown in FIG. 3.

If the language recognition and integration module 228 recognizes the "enabled" command, the user must adjust the headset 200 and speak the word "enabled" to activate the speech recognition wireless headset 200.

Reproduction of the word "possible" as an audio signal is produced via the microphone 206.

After the audio signal is changed to a radio wave signal by the transceiver 210, the transceiver 210 transmits radio wave “enabled” from the headset 200 to the antenna 214 of the headset interface unit 202.

A radio wave “enabled” signal is received from the antenna 214 by the receiver 220.

The receiving device 220 converts a radio wave signal into an audio signal, and the audio "enabled" signal is transmitted to the language recognition and integration module 228 through the audio input line 230.

In response to receiving the audio "enabled" signal, the language recognition and integration module 228 transmits a control signal to the off-hook terminal 232 via the control line 234.

In response to the control signal, the off-hook terminal 234 goes off-hook.

When the off-hook element is in the off-hook position, two audible passages are established between the headset 200 and the communication line 82.

The first audible path is a telephone jack 80, three-way coupler 72, I / O element 242, off-hook terminal 232, voice network circuit 224, transmission device 218 from the communication line 82. The antenna 214 and the transceiver 210 are transmitted to the headset 200 and the speaker 208.

The second audible path from the microphone 206 of the headset 200 to the transceiver 210, antenna 214, receiver 220, language recognition and integration module 228, voice network circuit 224, off-hook terminals ( 232, the I / O element 242, the three-way coupler 72, and the telephone jack 80 to the communication line 82.

With this equipment the user can receive incoming calls and talk to the caller through the headset 200 and the headset interface unit 202.

During the hands-free operation, the user presses the on / off button 204 of the headset 200, puts the headset 200 mounted on the head at the call position, speaks the telephone numbers of the place to be called, and then commands "dial." .

Say "end" after the numbers are over.

Separately, if the language recognition and integration module 228 recognizes the "enable" command, the user wears the headset 200 on his head, speaks a telephone number, commands "end", and "enables" and "dials". You can call out by ordering.

As mentioned earlier, the word "enabled" creates a pair of audio signal paths between the headphone 200 and the communication line 82.

The word "dial", which reproduces the audio signal, is generated by the microphone 206.

After the audio signal is changed to a radio wave signal by the transceiver 210, the transceiver 210 transmits a "dial" radio wave from the headset 200 to the antenna 214 of the headset interface unit 202.

A "dial" radio wave signal is received by the receiver 220 from the antenna 214.

The receiver 220 converts a radio wave signal into an audio signal and transmits an audio "dial" signal to the language recognition and integration module 228 through the audio input line 230.

In response to receiving the " dial " audio signal, the language recognition and integration module 228 must activate the DTMF line 238.

As is known, the language recognition and integration module 228 should also check the internal bus and register settings with "and / or" after receiving a "dial" signal.

An audio signal that reproduces the number of speech strings is generated by the microphone 206.

After the audio signal is converted by the transceiver 210 into a radio wave signal, the transceiver 210 transmits the radio wave signal "telephone number" from the headset 200 to the antenna 214 of the headset interface unit 202.

A "telephone number", which is a radio wave signal, is received from the antenna 214 by the receiving device 220.

The receiver 220 converts a radio wave signal into an audio signal, and the audio signal "telephone number" is transmitted to the language recognition and integration module 228 through the audio input line 230.

In response to receiving the "telephone number" which is an audio signal, the language recognition and integration module 228 transmits the DTMF string and the number of voice strings to the voice network circuit 224 that will operate the DTMF line 238.

The voice network circuit 224 then transmits the DTMF signal to the communication line 82 through the off-hook terminal 232, the I / O terminal 242, the three-way coupler 72, and the telephone jack 82.

An audio signal that reproduces the word "end" is generated by the microphone 206.

The audio signal is converted into a radio wave by the transceiver 210, and the transceiver 210 transmits a radio wave signal "end" from the headset 200 to the antenna 144 which is a headset interface unit.

The radio signal "end" is received by the receiving device 220 from the antenna 214.

The receiver 220 converts the radio wave signal into an audio signal and transmits the audio signal "end" to the language recognition and integration module 228 through the audio input line 230.

In response to receiving the audio signal "end", the language recognition and integration module 228 must activate the DTMF line until the next "dial" signal.

All the signals reproduce part of the user conversation.

The audio recognition line 230 enters the language recognition and integration module 228 and the bypass line 240 exits the language recognition and integration module 228.

The bypass line 240 signal allows the language recognition and integration module 228 to bypass DTMF lines 238 and DTMF devices in the language recognition module (unlike "able", "disable" and "phone number" signals). It has no special meaning.

When the transceiver call is complete, the user must press the on-off button 204 to disconnect the headset 200 from the communication line 82.

If the language recognition and integration module 228 recognizes a "disabled" command, the user must say "disabled" to disconnect the voice recognition headset.

An audio signal that is reproduced as "disabled" is generated by the microphone 206.

After the audio signal is changed by the transceiver 210 to a radio wave signal, the transceiver 210 transmits a radio wave signal "disabled" from the headset 200 to the antenna 214 of the headset interface unit 202.

The radio signal "disabled" is received by the receiver 220 from the antenna 214.

The receiver 220 converts a radio wave signal into an audio signal, and transmits the audio signal "not possible" to the language recognition and integration module 228 through the audio input line.

In response to receiving the " disabled " audio signal, the voice recognition and integration module 228 sends a control signal to the off-hook element 234 via the control line 234.

The off-hook element 234 goes on-hook in response to the control signal.

The open hook element 232 is opened between the communication line 82 and the headset 200 when the off-hook element 232 is in the on-hook position of the two voice signal passages.
