Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a communication terminal adapter connected to an integrated digital communication network.

[0002]

2. Description of the Related Art FIG. 5 is a block diagram showing a communication equipment system using a conventional communication terminal adapter shown on page 78 of a book "ISDN for communication staff" (publisher Rick Telecom). In the figure, 1 is an integrated digital communication network, 1a is a call control channel, 1a1 is transmission rate information, 1a2 is called number information, 1b is an information channel, 1b1, 1b2 and 1b3 are assigned information channels, 2a, 2b and 2c. Is a communication terminal device, 3 is a communication terminal adapter, 3b1, 3b2 and 3b3 are communication terminal device interfaces, 3c is an information channel switch, and 3d is an operation panel.

Next, the operation will be described. Here, it is assumed that the plurality of communication terminal devices 2a, 2b, 2c are communication terminal devices having no interface to the integrated digital communication network 1. Therefore, the communication terminal adapter 3 connected between the integrated digital communication network and the plurality of communication terminal devices 2a, 2b, 2c is provided with an interface matching between the integrated digital communication network 1 and each communication terminal device 2a, 2b, 2c, and an information channel. Controls switching of internal data and call control for communication line connection.

The call connection operation is started by the input of the call start key after the transmission speed information 1a1 and the called number information 1a2 to be sent to the call control channel 1a from the operation panel 3b of the communication terminal adapter 3 on the calling side are specified. In the communication terminal adapter 3 on the calling side, the communication terminal device interfaces 3b1, 3b2, 3b3 should be uniquely connected in the order of the calling of the communication terminal device in the order of young number (3b1, 3b2, 3b3). And

Transmission rate information 1a as call connection request information
1 and the called number information 1a2 reach the called side communication terminal adapter 3 through the call control channel 1a in the integrated digital communication network 1 and become in a calling state. When the communication terminal adapter 3 on the receiving side is in an automatic incoming call operation, the incoming call request is an immediate incoming call permission from the communication network on a first-come-first-served basis. When a manual incoming call is made, the incoming call activation key on the operation panel 3d permits the incoming call.

The incoming call request for which the incoming call is permitted follows the allocation of the information channel 1b in the integrated digital communication network 1 by the transmission speed information 1a1 by the information channel switch 3c in the communication terminal adapter 3, and the information channel for the incoming call. (For example, 1b1) are connected in ascending order of terminal device interface numbers (for example, 3b1).

The connection operation to the remaining two sets of communication terminal devices 2b and 2c is similarly performed by the transmission side from the transmission speed information 1a1.
The called number information 1a2 is transmitted to the integrated digital communication network 1 as call connection request information. On the receiving side, according to the allocation of the information channel 1b2 or 1b3 in the order of reception, the information channel data switch 3c sequentially connects to the terminal device interface number in ascending order 3b2 or 3b3.

That is, the information from the communication terminal device 2a on the transmitting side passes through the information channel 1b in the integrated digital communication network 1 and, if the first incoming state is reached, the above-mentioned information is set in the communication terminal adapter 3 on the receiving side. It is connected to the communication terminal device 2a on the receiving side through the terminal device interface number 3b1 determined by the order of arrival of first arrival.

[0009]

Since the conventional communication terminal adapter 3 is configured as described above, the communication terminal adapters 3a, 2b, 2c on the sending side and the receiving side are provided in the integrated digital communication network 1. Each information channel 1b1, 1b2, 1b3
When the connection is sequentially performed through the terminal adapter 3 and the terminal adapter 3, connection permission is sequentially performed in the order of incoming calls. However, the calling order from the calling side and the receiving order on the called side do not always match due to route differences when passing through the integrated digital communication network 1, and the terminal device interface on one side (calling side or called side) In the connection operation of the communication terminal equipment when the communication terminal equipment is already used, there is a problem that the connection correspondence between the corresponding communication terminal equipment, for example, the originating communication terminal equipment 2a and the receiving communication terminal equipment 2a is not always guaranteed.

The present invention has been made in order to solve the above problems, and even if a plurality of communication terminal devices are connected to one communication terminal adapter, they are in a connection state independent from each other, and it is as if the plurality of communication terminal devices are connected to each other. It is intended to provide a communication connection environment similar to that in which communication terminal adapters are connected in parallel.

[0011]

The communication terminal adapter according to the present invention has the same number of sub address number information (for example, 1, 2 and 3) as the number of terminal device interfaces (for example, 3).
3. By using an example of the identification information of the communication terminal adapter according to the present invention, each sub address number information and the terminal device interface number are uniquely associated with each other. In other words, the calling side uniquely associates the incoming subaddress number information with the terminal device interface number, and the incoming subaddress number information is automatically added to the outgoing information. The terminal device interface that should output the received information from the incoming subaddress number information added to the received information by uniquely correlating the number information and the terminal device interface number with the same rule as the calling side The number is discriminated.

Further, the communication terminal adapter according to the present invention holds the sub-address number information as a part of the abbreviated calling number and automatically sends the sub-address number information by sending the abbreviated number.

Furthermore, the relationship between the subaddress number information on the calling side or the subaddress number information on the called side and the terminal device interface number can be forcibly made different from the operation panel or the external control interface.

[0014]

In the communication terminal adapter according to the present invention, the subaddress number information on the calling side corresponding to each terminal equipment interface and the subaddress number information on the called side and the terminal equipment interface number are uniquely associated with each other, and the subaddress number on the calling side is associated. Since the call connection is permitted only when the information and the sub-address number information on the receiving side match each other, the terminal device interface numbers corresponding to the respective sub-address numbers can be connected to each other.

Further, since the sub-address number information is held as a part of the abbreviated calling number information, the sub-address number information is added to the outgoing information without any special processing.

Further, by making the correspondence between the sub-address number information on the calling side or the sub-address number information on the called side and the terminal equipment interface number compulsorily different, communication on both sides can be performed without physically changing the cable connection. Arbitrary logical connection relationships between terminal device interface numbers can be changed.

In FIG. 1, 1 is an integrated digital communication network, 1a is a call control channel, 1a1 is transmission speed information, 1a2 is called number information, 1b is an information channel, 1
b1, 1b2, 1b3 are assigned information channels, 2
a, 2b and 2c are communication terminal devices, 3 is a communication terminal adapter, 3a is an internal memory, 3a1, 3a2 and 3a3 are called subaddress number information in the shortened calling number information, 3a1.
1, 3a12, 3a13 are substation address number information corresponding to communication terminal equipment interface, 3b1, 3b2, 3
Reference numeral b3 is a communication terminal equipment interface, and reference numeral 3c is an information channel switch. Here, the incoming sub-address number information 3a1 is the communication terminal device interface 3b on the outgoing side.
1, the incoming subaddress number information 3a2 corresponds to the originating communication terminal equipment interface 3b2, and the incoming subaddress number information 3a3 corresponds to the originating communication terminal equipment interface 3b3. Further, the own station sub address number information 3a11 corresponds to the receiving side communication terminal equipment interface 3b1, the own station sub address number information 3a12 corresponds to the receiving side communication terminal equipment interface 3b2, and the own station sub address number information 3a13. Corresponds to the communication terminal device interface 3b3 on the receiving side. Further, it is assumed that the numbering of the incoming subaddress number information 3a1, 3a2, 3a3 and the numbering of the local station subaddress number information 3a11, 3a12, 3a13 are performed by the same rule, and here, the following correspondences are made. Shall be numbered. Incoming sub-address number information 3a1 to own station sub address number information 3a11 Incoming sub address number information 3a2 to own station sub address number information 3a12 Incoming sub address number information 3a3 to own station sub address number information 3a13

Next, the operation will be described. The communication terminal adapter 3 connected between the integrated digital communication network 1 and a plurality of communication terminal devices 2a, 2b, 2c having no integrated digital communication network interface includes an integrated digital communication network 1 and each communication terminal device 2a, 2b. , 2c, interface control, data channel switching control, and call control for communication line connection.

It is assumed that the internal memory 3a of the communication terminal adapter 3 on the calling side holds the called number information 1a2 and the called subaddress number information (for example, 3a1) as abbreviated calling number information. Therefore, at the time of abbreviated number calling operation, the called sub address number information (for example, 3a1) is automatically added to the called number information 1a2, and the call control channel 1a
It is transmitted to the integrated digital communication network 1 as the incoming call number information 1a2 and the incoming call sub address number information (for example, 3a1).

Transmission speed information 1a1 and called number information 1a2
Also, the call connection request information by the automatically added incoming sub-address number information (for example, 3a1) reaches the called communication terminal adapter 3 via the call control channel 1a in the integrated digital communication network 1 and becomes a calling state. . Incoming subaddress number information from the communication network (for example, 3a1)
Is checked and matched with own station sub-address number information 3a11, 3a12, 3a13 uniquely corresponding to the communication terminal equipment interfaces 3b1, 3b2, 3b3 preset in the internal memory 3a of the communication terminal adapter 3 on the receiving side. In that case, the incoming call is permitted immediately upon the automatic incoming call operation. When a manual incoming call is made, the incoming call activation key on the operation panel 3a permits the incoming call.

For the incoming call request which has been permitted to be received, the information channel switch 3c in the communication terminal adapter 3 takes out the information channel 1b in the integrated digital communication network 1 in accordance with the allocation of the transmission speed information 1a1. For example, 1b1) is connected to the terminal device interface number (for example, 3b1) corresponding to the local station sub-address number information (for example, 3a11) that matches the collation.

In this way, the communication terminal equipment 2a on the originating side
Information passes through the information channel 1b1 in the integrated digital communication network 1 and then matches with the called sub address number information 3a1 automatically added by the calling side in the called side communication terminal adapter 3 and corresponds to the corresponding terminal equipment interface. It is sure to be connected to the corresponding communication terminal device 2a on the receiving side via the number 3b1.

Further, as shown in FIG. 2, in the connection procedure in the communication terminal equipment 2b and 2c, the transmission speed information 1a1 and the incoming call number information 1a2 and the information are automatically added by the communication terminal adapter 3 on the calling side in the same manner. Receiving sub-address number information (for example, 3a2 or 3a3) is transmitted as call connection request information to the communication terminal adapter 3 on the receiving side via the integrated digital communication network 1. The communication terminal devices 2b and 2c on the calling side are always connected to the communication terminal devices 2b and 2c on the receiving side regardless of the order of arrival due to the route difference when passing through the integrated digital communication network 1. In addition, in the connection operation of the communication terminal device when the terminal device interface on one side (calling side or receiving side) is already used, the communication terminal device having the same name (for example, the communication terminal device 2 on the calling side)
Even if c and the communication terminal device 2c) on the receiving side are in a non-connected state, they are always connected correspondingly.

As described above, in this embodiment, the integrated digital communication network interface, the plurality of communication terminal equipment interfaces, the memory having the same number of sub-address number information as the communication terminal equipment interfaces, and the communication terminal equipment interface numbers are provided. A transmitting unit that performs outgoing / incoming operations by using uniquely corresponding sub-address number information,
A sub-address number information collating and matching is provided with a receiving unit that makes the information channel data in the integrated digital communication network correspond to the communication terminal equipment interface,
It is characterized in that the same communication terminal equipment interfaces of the communication terminal adapters of the transmitting side and the receiving side can be connected to each other.

According to this embodiment, the same number of pieces of sub-address number information as the number of terminal equipment interface numbers are set in the communication terminal adapters 3 on the calling side and the called side so as to uniquely correspond to the communication terminal equipment interface numbers. Since it is configured, even if multiple communication terminal devices are connected to one communication terminal adapter, the connection state will always correspond to each other, so the communication connection environment is as if multiple communication terminal adapters were connected in parallel. There is an effect that can be obtained.

Example 2. In the first embodiment, the incoming subaddress number information 3a1, 3a2, 3a3 and the terminal device interface numbers 3b1, 3b2, 3b3 are uniquely corresponded to each other by the same method on the calling side and the called side. However, as shown in FIG. 3, by setting the relationship between the incoming subaddress numbers 3a1, 3a2, 3a3 and the terminal device interface numbers 3b1, 3b2, 3b3 so as to be freely different correspondences, a plurality of communication terminal devices 2a, 2b and 2c are one communication terminal adapter 3
When the corresponding communication terminal device (for example, 2b) is being used by another communication terminal device when temporarily connected by another communication terminal device (for example, 2c), the communication terminal adapter 3 and each communication terminal device 2a are connected. , 2b, 2c, it is possible to freely change the logical connection without changing the physical cable connection.

Example 3. In FIG. 4, 3d is an operation panel, 3e is an external control interface, and 4 is an external control device. In the first or second embodiment, the incoming sub-address number information 3a1 sent to the integrated digital communication network 1
3a2 and 3a3 are held as a part of the abbreviated number information, and are automatically added to the incoming call address information 1a2 by the abbreviated number sending operation, but they are sent respectively, but manually from the operation panel 3d or through the external control interface. The same incoming sub-address number information from 3e (for example, 3
a1) is specified to make a call, and the incoming sub-address number 3 preset in the communication terminal adapter 3 of the receiving side is set.
By comparing with a11, 3a12, 3a13, the effect that the relationship with the terminal device interface numbers 3b1, 3b2, 3b3 can be changed to the same correspondence or arbitrary connection correspondence from the calling side can be obtained.

Example 4. In the above embodiment, the case where the number of communication terminal devices is three has been described, but the integrated digital communication network 1
Capacity and transmission speed information 1a1 determine the number of information channels n (= (capacity of integrated digital communication network) ÷ (transmission speed information)), even if communication terminal devices are added, one communication terminal adapter 3 Since they are connected to each other independently, it is possible to obtain the same communication connection environment as if a plurality of communication terminal adapters 3 were connected in parallel.

For example, when the primary group interface (capacity: 1536 kbps) is used as the integrated digital communication network 1 and the transmission speed information 1a1 is used at 384 kbps, the maximum number n of usable information channels is 4 (= 153).
6 ÷ 384) (however, the call control channel requires a separate line). Also, 64 kb as the transmission rate information 1a1
When ps is used, n is 23 (= (1536-6
4) ÷ 384) (provided that 64 kbps is used as a call control channel in this line).

Example 5. In the above embodiment, the incoming subaddress numbers 3a1, 3a2, 3a3 are set as the incoming address information 1
Although the call is added to a2, the present invention is not limited to the basic interface of the integrated digital network 1 in which the incoming sub-address number is defined, but is not transparent to the incoming sub-address number and is simply transmitted as one of the call control information. Even in the primary group interface of the information integrated digital network transmitted to the opposite station, the terminal device interface numbers 3b1, 3b2 and 3b3 between the opposite stations can be changed to the same correspondence or arbitrary connection correspondence. .

[0031]

As described above, according to the present invention, even if a plurality of communication terminal devices are connected to one communication terminal adapter, the connection states are always in correspondence with each other. There is an effect that a communication connection environment similar to that of connecting in parallel can be obtained.

In addition, there is an effect that a plurality of communication terminal devices can be connected on one integrated digital communication line up to the maximum transmission capacity of one communication terminal adapter to make the most effective use.
