Abstract

PURPOSE:To simultaneously realize a hot line function and a hand-free function by one touch, by executing automatically setting for making a loudspeaker, a microphone, etc. effective, by a private branch exchange, in the case when a multi-function telephone set is used. CONSTITUTION:When a service set button 12 to which a hot-line function has been set, of a multi-function telephone set MFT 10 which is installed in a sickroom 2 is pushed, a call signal is detected by a multi-function telephone set subscriber's circuit MLC 32. When a CPU 36 recognizes it, a B board ATT 40 of a nurse station 4 is called through a B board interface circuit ATI 35 by controlling a speech path circuit SW 3. When the ATT 40 responds to the call and the CPU 36 recognizes it through the ATI 35, the MFT 10 and the ATT 40 are connected in two directions, and simultaneously, a microphone 13 of the MFT 10 is set to an on-state. As a result, the MFT 10 and the ATT 40 go to a call state, and the MFT 10 side goes to a state that a call can be executed by hand-free.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a local telephone calling system, and particularly to a microphone (
The present invention relates to a private telephone calling system in a private branch exchange that connects a multifunctional telephone having a microphone (hereinafter referred to as a microphone) and a speaker, and an intercom having a microphone, a speaker, and a push button switch.

[Conventional technology]

Conventionally, as a service function of this type of local telephone calling system, there has been a so-called hotline function, in which a caller simply picks up the handset and calls a pre-registered party (called party).

[Problem that the invention seeks to solve]

With the hotline function of the conventional in-house telephone calling system described above, the hands-free function cannot be realized if the caller uses a general extension telephone without a speaker or microphone. Even when used, button operations are required to call the called party and to activate the speaker and microphone.
Therefore, it has the disadvantage that it is not possible to realize hands-free function with one touch.

[Means for solving problems]

The private telephone calling system of the present invention is set in advance when the multifunctional telephone is used in a private branch exchange in which a multifunctional telephone having a microphone and a speaker is connected to an intercom having a microphone, a speaker, and a push button switch. a calling means for calling a preset called party by pressing only the push button switch when the intercom is used with only the service set button; and a calling means for calling the called party using the microphone and the speaker; It is equipped with a means for making calls (hands-free function).

〔Example〕

Next, embodiments of the present invention will be described with reference to the drawings.

Fig. 1 is a system configuration diagram showing one embodiment of the present invention;
Figures (a) and (b) are top views showing an example of the multifunction telephone and intercom in Figure 1.

This embodiment is an example of application to a hospital.

The private telephone call system of this embodiment is comprised of a private branch exchange 3, a hospital room 1.2 and a nurse station 4 connected to the private branch exchange 3. The Yokonai switchboard 3 has an interphone subscriber circuit (hereinafter referred to as LC) 31 connected to a communication path circuit (hereinafter referred to as 5W) 33, and a multi-function telephone subscriber circuit (hereinafter referred to as M).
LC) 32, tone generator (hereinafter referred to as TNG) 34. A central control unit (hereinafter referred to as CP) that controls each of these circuits by the program etc. built in the relay board interface circuit (hereinafter referred to as ATI) 35 and the storage device (hereinafter referred to as MEM> 37).
U) 36.

In hospital room 1, there is an intercom (hereinafter referred to as IN) connected to LC31.
P) 20 is installed, and in patient room 2 a multi-function telephone (hereinafter MFT>10) connected to MLC32 is installed.Nursing station 4 has a relay stand (hereinafter ATT>40 connected to ATI35). is set up.

As shown in FIG. 2 (a), the MFT 10 is provided with several types of service buttons 12, one of which is set to a hotline function.

It is also assumed that the program is programmed to call the ATT 40 of the nurse station 4 as the hotline connection partner for MFTIO and 1NP2O.

Next, the operation of this embodiment will be explained with reference to FIG.

(1) When making a call from patient room 1 When the push button switch 22 of the lNP2O installed in patient room 1 is pressed, a call signal is detected at 31 on the LC, and the
When the PU 36 recognizes this, it controls the 5W 33 to call the ATT 40 of the nurse station 4, which is the destination of the hotline connection, via the ATI 35. At this time, I
The TNG 34 is connected to the receiving side communication circuit of the NF 20 via the 5W 33, and the ring tone is heard in the 1NP 2O.

Next, the operator of the ATT 40 at the nursing station 4 responds to the paging signal and sends it to the CP via the AT I 35.
When U36 recognizes it, it bidirectionally connects the communication circuit of lNF20 and ATT40 via 5W33 and becomes a communication state.
The lNP2O side can talk hands-free.

(2) When making a call from patient room 2, press the service set button 12 to which the MFTIO hotline function installed in patient room 2 is set.
When a call signal is detected by the LC 32 and the CPU 3'6 recognizes it, it controls the 5W 33 and calls the nurse station 4, which is the destination of the hotline connection, via the ATI 35.
At the same time as calling the ATT 40 of the MFTlo, the speaker 11 of the MFTlo is set to the on state. At this time, M F T 1
The communication circuit on the receiving side of 0 is connected to TNG via 5W33.
34 is connected and the MFTIO can hear the ringing tone.

Next, the person handling the ATT 40 of the nursing station 4 responds to the call and sends it to the CPU 36 via the ATI 35.
When recognized, it connects the communication circuit of MFTIO and AT 40 bidirectionally via SW 33, and at the same time
The microphone 13 of F T 10 is set to the on state.

As a result of the above, the MFTIO and the ATT 40 become in a talking state, and the MFT 101!11 becomes able to talk hands-free.

(3) When making a call from the nurse station 4, dial the extension number set for each patient room from the ATT 40 installed at the nurse station 4.
35, the CPU 36 recognizes this and sends a TNP 20 or MFT installed in the hospital room corresponding to the extension number.
10 and the ATT 40 are bidirectionally connected via the 5W 33, and at the same time, in the case of MFTIO, the speaker 11 and the microphone 13 are set to the ON state.

As a result of the above, the MFTIO or IN installed in each hospital room
ATT4 installed at P2O and nurse station
0 becomes a call state and AT from nurse station 4.
It is possible to call each hospital room by voice via T40,
No operations are required in each hospital room.

〔Effect of the invention〕

As explained above, the present invention enables the multifunction telephone to simultaneously call a preset called party with a single touch by pressing the service set button preset on the multifunction telephone or the push button switch of the intercom. When using , the Yokouchi switchboard automatically configures settings to enable speakers, microphones, etc.
It has the effect of realizing hotline function and hands-free function at the same time with one touch.

In the case of a hospital or the like shown in this embodiment, since the present invention is a one-touch operation of a push button, there is an advantage that it can be easily operated, especially by a person with a physical disability.
