Description

[Detailed Description of the Invention] [Summary] In a simple exchange telephone device, the type of telephone key operated on the telephone set during a call to an outside line is identified, and if the identification result is an outside line telephone key, the outside line under call is placed on self-hold. If the identification result is an extension phone key, the outside line in progress is placed on common hold.

[Industrial application field]

The present invention relates to an improvement in an automatic hold system in a simple telephone exchange.

Small businesses, workplaces, etc. accommodate multiple telephones and multiple central office lines or private branch exchange extensions (hereinafter collectively referred to as outside lines), allowing any telephone to make calls to the outside using any outside line. Simple exchange telephone devices that enable mutual telephone calls have been widely adopted.

Each telephone housed in such a simple exchange telephone device is equipped with an outside line key corresponding to an outside line and an extension key for mutual phone calls, and by operating the outside line key on any telephone, you can connect to the corresponding outside line and make a call. It becomes possible to make incoming calls, and by operating the extension telephone key, it becomes possible to make calls between telephones housed in the simple exchange telephone device.

Furthermore, this type of simple exchange telephone device usually has a hold function in which a telephone that is talking to an outside line temporarily puts the call on hold and then talks to another outside line or telephone. In addition, there are cases where the telephone puts an active external line on hold by operating a dedicated key, etc., and when another external line is placed on hold.
By operating the telephone key or the extension telephone key, there are cases in which an active outside line is automatically put on hold, and the latter is referred to as automatic hold.

Self-hold, which allows re-calling to an outside line placed on hold only to the phone that previously made the call, and common hold, which allows any phone to re-call, not just the phone that previously made the call. is being put into practice. Self-holding allows calls to be made smoothly because the telephone that was making the call before being put on hold always answers the call, and common holding allows calls to be transferred to other telephones, each of which has its advantages.

Therefore, it is desired that such self-reservation and common reservation can be easily selected and used.

[Conventional technology]

FIG. 4 is a diagram showing an example of a conventional simple exchange telephone device, and FIG. 5 is a diagram illustrating a conventional automatic hold process.

In FIG. 4, the simple exchange telephone device 100 has two telephones 1 (in order to distinguish between the telephones 1, they are indicated as 1-1 and 1-2, the same applies hereinafter), two outside lines 2, and are connected to extension circuit (EKC) 3 and external trunk (
BWT) 4.

Each telephone set 1 is provided with outside line keys CI and C2 corresponding to the respective outside lines 2-1 and 2-2, and is also provided with an extension line key I for mutual communication between the telephone sets 1. Further, the central control device (CC) 7 is provided with a self-holding mechanism 71 and a common holding mechanism 72.

When the outside line key C1 corresponding to the outside line 2-1 which is now available on the telephone 1-1 is operated, the central control unit 7 detects the operation of the outside line room 1IC1 via the extension circuit 3-1, and connects the network (NW). 5 has an extension circuit 3-1 and an outside line trunk 4.
-1, and set up a communication path p1 to connect the external line trunk 4.
-1 is placed in a calling state for the outside line 2-1. From now on, phone 1
-1 calls the called party via the outside line 2-1, and a conversation becomes possible.

In this state, while telephone 1-1 is talking to outside line 2-1,
When a call arrives on another outside line 2-2 and the telephone 1-1 that is currently talking operates the outside line key C2 to answer, the central controller 7 controls the operation of the outside line key C2 via the extension circuit 3-1. It is determined that automatic hold has been requested because the telephone 1-1 is clearly in step S1) and the telephone 1-1 is busy, and whether the outside line key C2 has been operated twice within the predetermined time limit. Monitor whether or not (steps s4 and S5)
.

If it is operated twice as a result of monitoring, the self-holding mechanism 71
(Step S6).

The self-holding mechanism 71 puts the communication path p1 set in the network 5 on hold and creates new communication paths p2 and p3.
, and transfer the currently active outside line 2-1 to a music on hold trunk (WT).
) 6 and also connect extension circuit 3-1 to external trunk 4-
2 and set the outside line 2-1 to a self-holding state. As a result, the hold tone is returned from the hold tone trunk 6 to the outside line 2-1, which was in the middle of a call with the telephone 1-1.
-1 becomes able to respond to an incoming call from outside line 2-2.

In this state, when the telephone m1-1 operates the outside line key C1 again, the central control device 7 detects the operation of the outside line key C1 via the extension circuit 3-1, and connects the communication path p2 set within the network 5. and p3, the held call path p1 is reset, and the extension circuit 3-1 and the outside line trunk 4-1 are connected. As a result, the telephone 1-1 becomes able to talk to the outside line 2-1 which is on hold.

Note that even if the outside line key C1 is operated on another telephone 1-2 to the outside line 2-1 which is in a self-holding state, the central control unit 7 does not enable the outside line 2-1 to respond.

Further, as a result of the monitoring in steps S4 and S5, if the outside mine lc2 is not operated twice within a predetermined time period, the common reservation mechanism 72 is activated (step S7).

The common holding mechanism 72 releases the communication path p1 set within the network 5 and creates new communication paths p2 and p3.
is set, the outside line 2-1 in use is connected to the hold tone trunk 6, the extension circuit 3-1 is connected to the outside line trunk 4-2, and the outside line 2-1 is set to a common hold state. the result,
The hold tone is sent back from the hold tone trunk 6 to the outside line 2-1 which was currently talking to the telephone set 1-1, and the telephone @1-1 becomes able to respond to the incoming call from the outside line 2-2.

In this state, when either of the telephones 1-1 and 1-2 operates the outside line key C1, the center side? The III device 7 detects the operation of the outside line telephone key C1 via the extension circuit 3-1 or 3-2, releases the communication paths p2 and p3 set within the network 5, and sets the communication path p1 or p4. , connects the extension circuit 3-1 or 3-2 and the outside line trunk 4-1. As a result, the telephone 1f- where the outside line key C1 was operated
1 or 1-2 can now talk to the outside line 2-1 that is on hold.

On the other hand, when the telephone 1-1 operates the extension key I to make a call to another telephone 1-2 while the telephone 1-1 is talking to the outside line 2-1, the second telephone 2-1 is activated in the same process as when the outside telephone key C2 is operated. If it is operated once, the self-retention mechanism 71 is activated, and if it is operated once, the common reservation mechanism 72 is activated.

[Problem to be solved by the invention 3 As is clear from the above explanation, in the conventional simple exchange telephone device, the self-holding mechanism 71 and the common holding mechanism 7
2, it is necessary to control the number of operations of the outside line telephone key C or the extension telephone key I, which complicates the operation and limits the selection time, resulting in problems of poor convenience.

[Means for solving problems]

FIG. 1 is a diagram showing the principle of the present invention.

In FIG. 1, 100 is a simple exchange telephone device, ■ is a telephone set, and 2 is an outside line.

The simple exchange telephone device 100 includes a self-holding mechanism 71 that allows only the telephone a1 that was previously engaged to re-call the outside line 2 that is in use, and a self-hold mechanism 71 that allows any telephone 1 to re-speak the outside line 2 that is currently in use. A common reservation mechanism 72 is provided.

Further, each telephone 1 is provided with an outside line key C for making an outside line call, which corresponds to each outside line 2, and an extension key I for making calls between the telephones.

Reference numeral 200 is a hold selection means provided according to the present invention, which identifies the type of telephone key operated on the telephone 1 during a call to the outside line 2.

[Effect]

When the telephone key type identified by the reservation selection means 200 is an outside line telephone key C, the self-retention mechanism 71 is activated, and the telephone key identified by the reservation selection means 200 is activated.

If the type is an extension telephone key■, the common reservation mechanism 72
is started.

Therefore, if a telephone calls to another outside line during a call to an outside line, it is necessary to resume the call with the held outside line again.
In addition, if a phone calls to another phone during a call to an outside line, the other phone can transfer the call to the outside line, and the user only has to operate the outside line key or extension key once, which increases the convenience of the simple telephone exchange device. improves.

Note that the same reference numerals indicate the same objects throughout the figures.

In the second cabinet, is there a central control unit (CC)? In addition to the self-reservation mechanism 71 and the common reservation mechanism 72, a reservation selection mechanism 73 is provided as reservation selection means 200.

In FIGS. 2 and 3, the telephone 1-1 has an outside line 2-
1, a call arrives on another external line 2-2, and when the telephone 1-1 operating the external telephone key C2 to answer the call, the central control unit 7 sends a call via the extension circuit 3-1. Outside line type WC
3), and since the telephone 1-1 is busy, it is determined that automatic hold has been requested (step 512), and the self-hold mechanism is activated based on the outside line telephone key C2 identified in step Sll. 71 is selected and activated (step 513).

The self-holding mechanism 71 sets the external vA2-1 to the self-holding state in the same manner as described above. As a result, only the telephone 1-1 is able to resume the call with the on-hold outside line 2-1, and the other telephone 1-2 becomes unable to answer the call.

Note that the telephone 1-1 that is talking to the outside line 2-2 is using the outside line key C.
1 and responds again to the on-hold outside line 2-1, the outside line 2-2 is set to a self-hold state through the same process.

On the other hand, when the telephone 1-1 operates the extension telephone key ■ to make a call to another telephone 1-2 while the telephone 1-1 is talking to the outside line 2-1, the central control unit 7 sends the extension telephone key I via the extension circuit 3-1. Step 511), and since the telephone 1-1 is busy, it is determined that automatic hold has been requested (step 514), and common hold m is detected based on the extension phone number I identified in step Sll. The system 72 is activated (step 515).

The common holding mechanism 72 sets the outside line 2-1 to the common holding state in the same manner as described above. As a result, the telephone 1-2 can also talk to the outside line 2-1 on hold, and the incoming call from the outside line 2-1 can be transferred from the telephone 1-1 to the telephone 1-2.

Note that when the telephone 1-1, which is currently talking to the telephone 1-2, operates the outside line telephone key C1 and answers the on-hold outer edge 2-1 again, the telephone 1-2 enters the self-hold state, and the outside line 2-
Telephone 1-1, which is currently talking to telephone 1, operates extension key I to answer the telephone 1-2 that is on hold again.
1 becomes a common pending state.

As is clear from the above description, according to this embodiment, when the telephones 1 to 1 operate the outside line telephone key C1 while talking with the outside line 2-1, the self-holding mechanism 71 is activated and the outside line 2-1 is connected to the outside line 2-1. If the telephone a1-1 operates the extension key I during a call to the outside line 2-1, the common hold mechanism 72 is activated, and the outside line 2-1 is answered by the telephone 1-1. The other telephone 1-2 also responds and transfer is possible.

However, the telephone set 1-1 can be put on hold only by operating the outside vA telephone key c2 or the extension number evacuation I once.

Note that FIGS. 2 and 3 are only one embodiment of the present invention, and the number of telephones 1 and outside lines 2 that can be accommodated is not limited to what is shown in the figures, and many other modifications may be made. In either case, the effects of the present invention remain the same.

C. Effects of the Invention] As described above, according to the present invention, in the simple switching telephone device, a telephone that has made a call to another outside line during a call to an outside line must always resume the call with the held outside line. Furthermore, a telephone that has made a call to another telephone while making a call to an outside line can transfer the other telephone to the outside line, and the operation is simplified and the convenience of the simple exchange telephone device is improved.
