2. Description of the Related Art Recently, multi-function telephones having various functions have become widespread, and in particular, in a company or the like, a multi-line service is provided by linking the multi-function telephone with a PBX (private branch exchange). Is becoming known.

In the multi-line service, a plurality of telephones are divided into a parent telephone and a child telephone, and which parent telephone the child telephone is subordinate to is registered in advance in the PBX. Then, the PBX simultaneously notifies the parent telephone of an incoming call to an arbitrary parent telephone and the slave telephones subordinate to the parent telephone of the arrival of the call. That is, both the master phone and the slave phone are ringing at the same time. At this time, the call can be answered from either the parent telephone or the child telephone.

In this multi-line service, in a company, a boss holds a master telephone and a subordinate of this boss holds a slave telephone. As a result, a call to the boss can be connected to the parent phone of the boss after the subordinate has answered.

It is also possible that a plurality of bosses each hold a parent telephone set, while a single sub-phone set is held by one subordinate. In this case, the child telephone is provided with a function of transferring a call to a specific parent telephone by the operation of the holder.

As described above, according to the multi-line service, when a boss is absent, a call to the boss can be answered by his / her own telephone without a specific subordinate leaving his / her desk. There is. Further, it is possible to save the trouble of the boss answering unnecessary calls by determining whether or not the subordinate answers the call once and the call is to be transferred to the boss.

On the other hand, the spread rate of cordless telephones has been remarkable in recent years, and cordless telephone systems having a plurality of call zones have come to be used particularly in PBXs. This system has the advantage that you can make and receive phone calls wherever you are in the business.

[0008] Here, the number of those using a cordless telephone for the above-mentioned multi-line service is also increasing.

[0009]

However, when using the above-mentioned multi-line service with a cordless telephone,
The following problems occur.

For example, when a cordless telephone is used as a master telephone held by the boss, and when the boss brings the cordless telephone and goes out / away, the call telephone held by the subordinate is also received when an incoming call is made to the boss. However, it is difficult to determine whether or not the superior can answer the phone.

Therefore, even if the boss tries to answer, the subordinate will take up, or the other party will judge that the other party is absent and stop calling while the boss and subordinate do not respond. It is causing the decrease.

Therefore, the present invention has been made in view of the above problems, and at least two telephones are connected in a multiline manner, and even if an incoming call to one telephone is answered by the other first, By continuing to call the telephone, if one telephone answers, it is possible to switch the call connection from the other telephone to the one telephone, and technically aim to improve serviceability. It is an issue.

[0013]

In order to solve the above-mentioned problems, the present invention is as follows. This will be described based on the principle diagram of FIG.

According to the present invention, at least two telephones among a plurality of telephones 1 connected to the exchange 2 are connected in a multi-line to notify the parent telephone 1a and the child telephone 1b of an incoming call to the parent telephone 1a at the same time, and at the same time, the parent telephone 1a. In the telephone exchange network in which both the telephone 1a and the sub telephone 1b can respond, the exchange 2 is provided with a switch circuit section 2a, a signal transmitting means 2c, and a control means 2b.

The switch circuit section 2a is for switching connection / disconnection of a telephone line. The signal transmitting means 2c transmits an interruption signal to the slave telephone 1b during a call. This is, for example, an audio signal. Further, a lamp may be provided in the slave telephone 1b and the lamp may be turned on by an interrupt signal.

The control unit 2b has the above-mentioned switch circuit unit 2a.
And controlling the signal transmission means 2c. Further, the exchange 2 is provided with a timer 2e for measuring a specific time, and after the response of the slave telephone 1b, the timer 2e is provided.
The incoming call notification to the parent telephone set 1a may be continued only within the clock time. The start / stop of the timer 2e is controlled by the control unit 2b.

Further, the exchange 2 is provided with a memory 2d for registering whether or not the parent telephone 1a is a cordless telephone, and based on this, an incoming call notification to the parent telephone 1a is performed even after the child telephone 1b responds. It may be determined whether or not.

[0018]

According to the present invention, when a call is received to a master telephone connected by multi-line, in the exchange, the control unit notifies both the master telephone and the slave telephone of the call arrival.

When the slave telephone responds to the call arrival notification before the master telephone, the control unit operates the speech path switch circuit unit to connect the call to the slave telephone.
At this time, the control unit continues to notify the parent telephone of the incoming call. As a result, if the parent telephone responds to the call incoming notification while the child telephone is talking, the control unit causes the signal transmitting means to transmit an interrupt signal to the child telephone.

The holder of the child telephone which recognizes the interrupt signal, for example, the voice signal disconnects the line (hooks the handset).
By doing so, the control unit can operate the switch circuit unit to switch and connect the call from the slave telephone to the master telephone.

Further, when the slave telephone answers, a timer is started to measure a specific time, and if the master telephone does not respond within this specific time, the incoming call notification to the master telephone can be stopped. . Here, a signal indicating the elapse of a specific time may be further transmitted from the signal transmitting means to the slave telephone. As a result, the holder of the child phone can
It is possible to recognize that the specific time has passed, notify the other party that the holder of the parent telephone cannot respond, and disconnect the line promptly.

Further, when the exchange is provided with a memory for registering whether or not the parent telephone is a cordless telephone,
When the cordless telephone refers to this memory when the call to the parent telephone is received, the control unit can continue the call incoming notification to the parent telephone even after the response of the child telephone. In other words, when it is difficult for the holder of the child phone to determine whether or not the parent phone is ready to respond, such as when the holder of the parent phone carries a cordless phone and is away from the desk, The holder of can respond immediately without waiting the caller.
