[Detailed description of the invention] name of invention Technical field of call connection and transfer equipment in telephone exchanges The present invention provides, for example, in a telephone exchange facility having an extension connection function such as a PBX, Specified relay lines and extension lines are connected to dial devices, etc. installed on the machines attached to them. Initiating the connection and transfer of calls initiated by using connection and transfer (referral/1ransfer). The present invention relates to a device configured to:

Description of prior art It is possible to connect or transfer one extension to another number within the switching facility. For example, in telephone exchanges such as private automatic branch exchanges (PABXs). The connection and transfer (or connection switching) functions are already known and available in -C. Also, 2 A paging system that allows calls to be relayed to the person to whom an extension is assigned. The general principles of implementing systems in exchange facilities are also well known. This kind of base An example of a PAB used in connection with Telephone Corporation's PABX facility. S/n344 basing system and P S/1 [21-844 basing There is something that is introduced as a management system. The first type of paging facility is the switchboard staff in up to 20 different basing zones within its jurisdiction. This is an attempt to place it. It has a call capacity of 10 and the paging is different. can be carried out simultaneously for people in different zones. As standard equipment One person in every zone by using ancillary equipment that can be incorporated. It is also possible to base things at the same time. The second type of basing mechanism is Staff will be placed in a maximum of two paging zones within the jurisdiction of the switchover. Ruled table 8358-500098 (5) It was attempted to be used as It has a call capacity of 6 and a maximum of 20 This allows paging of only one zone at a time for 00 extensions.

In connection with telephone systems, the general principle of using telephone answering machines has also already been established. It is a well-known place.

The purpose of the invention is to provide connection and transfer for calling parties within this type of switching facility. The aim is to make the procedures carried out more effective and simple. The invention is an exchange Predetermined trunk lines (stations) and extension lines within the facility automatically change these numbers. A procedure known as a connection method is used to connect It is designed so that it can be connected to or transferred to a telephone answering machine. At present, the city Most field-based paging systems operate completely independently of exchange equipment. It is something to do. A small number of systems of ponds linked to these systems and exchange facilities. If you wish to call someone who is away from the room where the telephone is located, The calling party has the possibility that the called party will be connected to the paging system. i.e. the scales he is searched for by basing, and the particular system The assumption is that you must be aware of the procedures involved in It operates according to the conditions. Also, at this time, generally available telephone responses Most telephone answering systems are connected to serve individual extensions and It is activated by operation.

How to solve technical problems One object of the present invention is to improve the paging system by converting its paging function into a replacement function. to link to a telephone switching system so as to function as part of a built-in The aim is to provide a system solution for this. According to the present invention, the paging setting If the extension that is to be transferred to the It's starting to get separated. According to one embodiment of the present invention, this This is done by dialing a code through the telephone.

Once the paging function is connected, paging for that particular one-time person is As long as the extension of p1 is connected to the caller in the normal way, this is done via the operator connected to another extension or connected externally via direct dial whether directly or indirectly.

In the case of the telephone answering machine mentioned above, the telephone answering machine is an integral part of the switching system. are connected to the exchange so as to form a should be encouraged to be used.

According to the invention, such extensions as are to be transferred to a telephone answering facility are themselves It can be connected or disconnected from the telephone answering function.

In one embodiment of the invention, this means that the code is sent via the telephone of the associated extension. Maybe by dialing the message-6 on the telephone answering machine This is done in connection with the recording of the Once the connect or transfer function is connected, the caller is already In the embodiment disclosed in You will be notified of the length of your stay, etc., and you can leave a message for the called party depending on your preference.

A characteristic configuration of the present invention is that the banks of paging equipment and telephone answering machines are arranged in the form of extension lines. connect to switching equipment and have them ring via a main number or extension. and either the paging facility or the telephone answering machine is automatically connected. or for a transferred extension, through which the caller is connected to that extension; or information about the connection or transfer and the reason for the connection or transfer or The system is configured as a receiving organization to receive additional information such as time away from work. The caller may be able to connect to the extension or provide information in advance through paging and connection/transfer. the desired connection to or to the relevant extension without expending any steps or other effort. Related information table 8858-500098 (6) It is designed to be carried out within the scope of the exchange function to obtain the following.

In a further development of the inventive concept, in connection with an exchange of the type already disclosed, Paging and answering machines with highly advanced connectivity or transfer capabilities Relatively detailed information about nine complete synthetic schemes is provided.

The above configuration is achieved by a system solution method that establishes the exchange as a whole. It does not impose any additional burden on the caller. Automatic connection and The function of dynamic transmission is simplified such that an extension initiates the function. involved The caller is aware of the existence of a paging system and still has no way of applying paging. There is no need to know the order. The caller uses the normal connection equipment at the switching facility. connected to the person to be paged via the location. This means that the person is dial the response code using the nearest telephone in response to the It is done by The system is also the simplest as a paging system. In other words, if one person wants to pursue another person, the former will page the latter. The system form is such that it is sufficient to simply indicate that the It is something. These employ a wireless system known as a pipe pager. can be used.

According to the present invention, people who only occasionally require the paging feature can use the paging system. does not need to be permanently connected to the system. That is, these people have individual pages. mechanism is not assigned.

If necessary, these people can also obtain page facilities from the page facility bank or pool. can be assigned. The manner in which these page mechanisms are connected to the system depends on the usage. so that the user is prompted to dial the code via their own telephone. The phone number is followed by the page facility number assigned to him. when needed In this I aspect, the number of page mechanisms is assigned only to extensions. Optimal use of the paging system can be achieved by limiting It is what makes it possible.

Insofar as the telephone answering system is involved, the extension to be connected to this telephone answering facility. can themselves be connected and disconnected to the desired telephone answering function.

This is done by dialing a predetermined code through the user's own telephone. Very easy and simple to achieve. 7r) The code consists of a number of predetermined Of the responses received, the one that corresponds to the desired response may probably suggest the desired time away from the desk, etc. Served. When this type of call connection function is connected, the caller can , you will be guided to a telephone answering machine, where you will be notified of your return schedule or time away from work, etc. You can leave a message for the called party if you wish.

Brief description of the drawing A preferred embodiment of a device having sub-essential features of the invention can be seen with reference to the accompanying drawings. It is explained below. Here, No. 111a should preferably be a microcomputer type, with some type of extension. related to the connection and transfer of Internal traffic configured to store some information, including The basic diagram of the PABX system, including the internal traffic volume detection device, is shown in Figure 2. According to the invention, within the scope of the telephone exchange selecting system disclosed in FIG. 3 is a basic connection diagram showing a configured telephone answering function.

Description of the preferred embodiment According to the previous explanation, the PABX is of an already known type, for example Swedish Telegraph and Telephone. A PABX model (PABX model) vA-844 is used; A connection facility (Sweden Patent No. 7802725-7) is provided. mentioned earlier Additionally, a paging system is connected to the associated PBX. According to the invention , after any call and answer, and automatic connection is requested. 8 (7) Conversations that are optionally forwarded to the paging function are transferred to the SLP in FIG. connected via a special basing n path indicated by . Replacement equipment and this page The device is designed according to conventional procedures and has a conventional construction according to the first factor. .

Connection of incoming calls to extension A' where the telephone is automatically referred for paging This may be carried out in any of the following three ways as desired.

a) via one operator/monitor with connection terminal 1vTe;

The terminal comprises an operator unit TA and a data terminal JvDTT. are doing. It is also equipped with a printer S.

b) Performed via paging circuit 8LP'i.

This paging circuit receives an audio signal, i.e., a sound machine, according to the previously disclosed aspects. The device is configured to generate a signal from the device. In this case, the caller himself Ringing mechanism P-8″6k2 Make a connection to

C) directly through the paging circuit 8LP. In this case, the calling party Automatically connected for browsing.

All three aspects mentioned above are incorporated in the design of the switch, and the necessary The period of time to be used is also selected as desired. The actual switching equipment is only one of the above three modes. may be operated by two.

Extension A' has a cord and a page by dialing this followed by the number indicating the expected return time in minutes. begin his transfer (reconnection) to the operating facility. The former code usually consists of two numbers. The latter number combination usually consists of four digits. of the present invention According to the concept, extensions that only occasionally require automatic call connection are One page facility can be allocated from the file. In this case, dial operation The number string to be assigned is 3 Contains the page mechanism number. There is a possibility of selection between said two or three embodiments. In addition, if the statement requires dialing a biphasic number.

The initiation of said automatic connection is preferably carried out by a unit μ consisting of a microcomputer. D monitors the traffic within the PBX and generates control functions within the switching equipment. This means that the extension has connected itself for paging. should be kept in mind. Also, the expected return time and pages to be exclusively used or selectively used. Pay attention to the mechanism number. However, if this information is included in the procedure shall be. If the exchange uses a computer device HVD=i, this computer a computer device together with said unit, preferably directly or via a data transmission system; If the computer equipment or data transmission system has the ability to communicate in both directions, It has the ability to be controlled via a connected terminal (see terminal Te above). This is extension 14 of the exchange. The necessary information, if the information about it can be put into the computer device. will be transmitted from unit μD to computer HVD.

When extension A', which was automatically connected in the above manner, is called, the operator/supervisor A connection is established to point (Te). This aspect connects by direct dialing. It is desirable to connect caller A, representing another extension, to the operator/monitoring point. “Caller A” is used when connecting to the desired extension using a paging facility. Decide whether to do so via

Unit μD is within reasonable range from the register REG contained within the exchange! s, receive the number When the unit receives a message, the number entered in the register will replace the operator so that Register REG/T now connects the caller to the operator.

When the operator answers the call, the unit μD sends a message to the main computer HVD. The number will be sent.

Tou 枦ben;;′− 5 Sign table Showa 58-500098 (8) This signal includes the extension number and the number of the active operator terminal. child Here, information is sent from the main computer HVD to the OheV-p stage. , is displayed on the corresponding data terminal /l/DT of this station. this The information includes the extension number and name, as well as whether the extension is automatically connected to the paging facility. Contains details including an indication of what has been continued. Estimated return time of extension and Details of the page mechanism number can also be displayed.

Connecting the calling party Att to the desired extension A', from the operator station. and in a manner determined by the operator. That is, the operator It can be forwarded to the paging facility via relay connector PR. Operate Data also tells the caller that the person he called can be located through a paging system. You may also be advised of the procedures required to page the extension in question. Ru. 1 seat by operator.

6 In the case of connected external traffic, the system , call connection information is displayed on the operator's data terminal.

The second aspect mentioned above is for connecting the calling party via the basing circuit SLP. This circuit SLP is for generating audio signals from audio equipment. Ru. This feature allows the caller to automatically transfer their phone to the paging facility. It is used to determine whether or not to connect to any extension. No. The situation shown in Figure 1 relates to an internal call.

In limited cases where traffic coming from an external source is involved, this type of operator connectivity Mode “a” is used for rough KM, but for direct dial traffic Embodiment "C" is used.

When unit μD receives the actual extension number from REG-L, this unit The number in the register of is exchanged with the number relating to circuit SLP. This new number is In FIG. 1 it is designated as Alr-nr (the number it is called).

The register now connects the caller to the paging circuit SLP, which extension is connected to the paging facility and access (calls) to it is For example, it indicates that this can be achieved by redialing the M number. To do this, audio signals are generated from audio equipment.

If the caller takes advantage of the opportunity to transfer his call through the paging system, The called party uses the nearest telephone in the switching facility to respond to this paging system. Upon dialing the code, a connection is established with the desired extension. For this , the called party being paged is connected to a blank answering number in the paging circuit. child The number is designated as '5varsnr' in the figure.

Yet another aspect is to send the calling party to the paging mechanism "P" via the paging circuit SLP. -8’6k”. This aspect outgoing calls as long as they are made to an extension that automatically connects the phone to the paging facility. Used when it is desired to automatically connect users to a paging facility. child The connection method applies to internal traffic as well as directly dialed Also applies to external traffic.

In the former case, REG-L is used, and in the latter case, REG-DU is used. Ru.

When unit μD receives the current extension number from REG-L or REG-DU, This unit converts the number in the register into the number of the paging circuit SLP, i.e. “A”. 41r-nr”.

Register REG-L now connects the caller to the paging circuit. unit at the same time p-8ok” p-8ok” A signal is sent to start. This signal is connected to the connection in Figure 1. This signal contains specific information about the desired extension. , usually an extension number or an assigned page facility number9 Sign table Showa 58-500098 (9) It consists of 4 numbers. The called party must use the nearest telephone within range of the switching facility. by going to the website and dialing the paging system response code. respond to paging.

This telephone is connected to the answering number "8.darsnr" for the paging circuit. , this establishes the connection.

Figure 2 shows the case where the user's own extension number is connected to a centrally installed telephone answering machine. This shows that. The function in this embodiment is to connect a PBX with call connection equipment to Vasing circuit that allows for th rougll co-connection This is achieved by combining with 8NR/G and AMR/TC. According to the invention , this feature is initiated from the user's own phone in one of two ways: It can be done.

d) By simply dialing a code (usually two digits).

e) Dial the code plus the combination of numbers (usually 2 numbers + 4 numbers). Especially 0 Ru.

When the code for automatic call connection is received by the register, unit μD connects the call. recognizes that the extension initiating the connection wants to be connected to a central telephone answering machine. Ru. This unit knows which telephone answering machines are free and can Select an answering machine and send a message to the extension number to which the selected telephone answering machine is connected. and that subsequent calls of Base C to the initiating extension should be connected. recognize.

In the case of an embodiment in which only one code is dialed, the unit μD registers Replace the number in the REG with the extension number to which the selected answering machine is connected.

The register now connects the starting extension to the selected telephone answering machine. This extension the user assigned to him by dialing the digits through his telephone For controlling the telephone answering machine and in the desired manner known as - next information, the unit μDK The recording of the necessary information in the telephone and the free selection of telephone answering machines are all in accordance with the above-mentioned aspects. However, the initiating extension is not connected to the selected telephone answering machine. the Alternatively, the unit μD communicates directly with the telephone answering machine based on the received number combination. believe The programmed response message will be selected. starting extension All incoming calls to the selected You will be directed to a telephone answering machine (extension number).

By dialing the code number through his own telephone, he can The user of the extension who requested automatic connection to the answering machine will be automatically connected to the assigned telephone answering machine. He was able to establish a connection and this allowed him to send a secondary message to You can check Nraka's incoming messages.

This check can be done by communicating directly with the telephone answering machine or via the unit μD. You can do more. For direct communication, dial 22 to the telephone answering machine. Connections are made via standard inputs or special inputs. Connection is made via standard input the unit connects to the extension by forming a connection through a bypass. , announce that the check is possible. If the connection is formed via a special input In this case, no such information is required to be provided to the unit. telephone answering machine By dialing valid digits through your telephone after a connection has been made to Control takes place.

When communication is carried out via the unit μD, for the standard input of the telephone answering machine, , some connection will always be formed and the unit will be bypassed. d" will be initiated by a check.

If it is desired to be able to check the telephone answering machine from any extension, this The possibility is to continue some combination of numbers after the code number for checking. It can be made into reality by

Automatic call connections can be abandoned in the manner already described.

The above points regarding automatic call connection can basically be applied to automatic call forwarding as well. . Sleeping involving vasing, the functionality of the device described above is in accordance with the following description: .

For example, a person with extension #r "1t04" will base all calls to his extension. There may be times when you want to connect to a processing facility.

This person has a specific number °“12” from the bank or pool of the portable paging device. extraction device. He also used his phone to write the code ``81''. °82″ and 88″ to connect the desired paging equipment,” By continuing with 1500'' and diamond/I/''j, he returned at 15.00. can be instructed to do something.

He also has a missing code (selectively below “a” is required) 81 15 00 12 and in addition the extension number ° “1804” can be read on the extension marker. Ru.

4 Calls to extensions belonging to the switching facility are registered in register REG-LK and dialed directly. The external call register REG-DVi7Cil is made by the external call register REG-DVi7Cil. via operator The call made is registered with REG-T.

Extension ° “1804” is requested ffl,? , the number stored in register REG is exchanged via unit μD to the extension number corresponding to:

a) reachable to an operator stage or operator station; Group number (code 81).

b) Baging equipment code (Code 82) pacing circuit S L P ,) or C) A paging circuit (code 83) corresponding to the paging function. This is a page machine The mobile device °°12" is connected to the selected code on extension "1804". Therefore, it involves the simultaneous transmission of a signal indicating that it should be driven.

As long as the equipment ゛12'' is activated, the called party must call the nearest 9 extensions in the switching system. and dial the response code containing the number of the pager, i.e. 85-12''. file. The microcomputer μD detects this and changes the number 8 in REG-L. Convert 5-12 to the response number "5varslr" for the paging circuit SLP. , thereby establishing a connection via fisLP.

Therefore, the unit μD determines whether the call is to be connected directly to an extension or whether that extension is Whether call connection (operator monitoring point), transfer, paging, or answering The configuration is such that it can be determined whether the

If the call connection is to be made to an operator (or monitoring point), the operator When the answer is received, the unit μD sends a signal to the HVD to instruct the HVD to Display the stored information (direct detailed information) in a visible form on the terminal. .
