Description

DETAILED DESCRIPTION OF THE INVENTION [Overview] In a switching system in which a subscriber class is identified and a switching process is performed in a system in which a DP signaling terminal and a PB signaling terminal coexist, at the time of initial setting of a system file,
DP class data is written from the fixed storage memory to the read / write memory, and when the identification code of the PB signal receiving section is detected, it is rewritten to PB class data. When the terminal makes a call,
The subscriber circuit to which the terminal belongs is connected to the PB signal receiving section through the exchange, and the subscriber circuit receives the dial information from the subscriber circuit when the DP signal is received, and the PB signal receiving section receives the dial information from the PB signal receiving section. Since the subscriber class is automatically identified and the exchange processing is performed, it is not necessary to set the subscriber class data of each terminal in the system file at system startup.

[Industrial application field]

INDUSTRIAL APPLICABILITY The present invention can automatically set the subscriber class data necessary for performing the exchange processing in the exchange in the system file, and can automatically determine the subscriber class at the time of calling to perform the exchange processing. The present invention relates to an automatic creation of subscriber class and a class determination method.

A private branch exchange (PBX) has a system file in a storage device (main memory), in which information such as extension numbers, telephone tiers (classes), additional service contents, and signaling systems is registered for each subscriber. Then, the exchange process is performed based on the information, and it is necessary to create such information in the system file.

In addition, there are a DP method that uses a rotary dial and a PB method that uses a push button as a signaling method for transmitting a dial signal to a telephone, and on the exchange side, depending on such a difference in signaling method, Since the dial information is processed differently, it is necessary to distinguish between DP class and PB class automatically.

The present invention is a system in which two specifications of dial pulse (DP) / push button (PB) type dial signals of a telephone (terminal) are mixed, and dial reception is DP type telephone with LC and PB type by the station data of software. The telephone is an exchange processing method that receives each at PBREC. Depending on whether PBREC is connected, P
Create a system file with D-class or DP-class data, and for the system file with PB-class data, for each phone, depending on whether CC detects dial reception information from LC or PBREC. It is an object to provide an automatic creation of a subscriber class for discriminating a PB class or a DP class and a class discrimination method.

[Conventional technology]

Conventionally, subscriber class data in the system file must be set for each subscriber on the system file by an external input / output device, etc., and the exchange performs the required exchange processing by referring to this information for each call. Was doing.

[Problems to be solved by the invention]

However, this method of setting subscriber class data for each subscriber using an external input / output device requires a lot of time and effort to set data for each subscriber when the system is started up, and is not economical. There is a problem that only the subscribers of the specified method can connect, and if the set subscriber class data is DP class, the call processing cannot be performed even if the terminal of the PB method is connected. It was

[Means for solving problems]

The present invention is intended to solve the above problems of the prior art, and has a principle configuration as shown in FIG.

The exchange system shown in FIG. 1 connects a subscriber circuit (101) having a function of receiving a DP signal and a PB signal receiving section (102) having a function of receiving a PB signal to an exchange (103),
Exchange processing is performed by discriminating a subscriber class of a terminal in a system in which terminals of DP signal system and terminals of PB signal system are connected, which are connected via a subscriber circuit (101).

A fixed storage memory 104 stores a system file having DP class data as subscriber class fixed data as an initial file.

Reference numeral 105 denotes a read / write memory in which variable station data and a system file in which a program is set are written.

An identification code is given to each of the subscriber circuit (101) and the PB signal receiving section (102).

At the start of system operation, software for system replacement processing is loaded from the fixed storage memory (104) into the read / write memory (105). The subscriber class data is set to the DP class as tentative data at this point.

This file can be used in a system to which only DP telephones are connected.

However, when a PB telephone is connected, the PB dial signal is
Since it is received by REC, it is necessary to connect LC with PB telephone and PBREC.

In order to make the connection, the PB class information is required on the subscriber class data, and the CC detects the assigned identification code in the PB signal receiving section (102) to connect the PB telephone to the system. The read / write memory (105) is rewritten from the temporary data to the PB class.

Furthermore, in a system in which PB and DP telephones coexist, that is, it is necessary to receive the dial signal of the PB telephone at the PB signal receiving unit (102), and it is not known which telephone is the PB telephone. All are regarded as PB phones and rewritten to PB class. When the terminal makes a first call, the subscriber circuit to which the terminal belongs is connected to the PB signal receiving section (102) via the exchange (103).

By doing so, the dialing signal is received from the subscriber circuit (101) when the call is made from the DP telephone and from the PB signal receiving unit (102) when the call is made from the PB telephone. Will be able to, and the subscriber circuit (10
When received at 1), DP class, PB signal receiver (10
When it is received in 2), it is discriminated as PB class and exchange processing is performed.

[Work]

In the system of the present invention, in a system in which terminals of DP signal system and terminals of PB signal system may coexist, at the time of initial setting of the system file necessary for exchange processing, first set DP class data, then When the presence of a PB terminal is determined by detecting the identification code of the PB signal receiving unit, the system file is rewritten to PB class data. When the terminal makes a call, the subscriber circuit to which the terminal is connected is passed through the exchange.
Connected to PB signal reception, when the subscriber circuit detects the DP signal, it receives the dial signal from the subscriber circuit, and when the PB signal receiver receives the PB signal, it receives the dial information from the PB signal receiver. As a result, the subscriber class of the terminal is automatically discriminated and the exchange process is performed using the PB class system file.

〔Example〕

FIG. 2 shows an embodiment of the method of the present invention.
1 is a DP signal type telephone, 2 is a PB signal type telephone, 3,
4 is a subscriber circuit (LC), 5 is a circuit switching connection device (NW), 6 is a PB signal receiving unit (PBREC), 7 is a central control device (CC), 8 is a memory device (MM), and 9 is an initial stage. Settings (IP
L) key.

FIG. 3 is a flow chart for explaining the class setting method at the time of initial setting according to the method of the present invention.

An embodiment will now be described in which the DP class is set as the subscriber class data in the initial file.

In FIG. 2, a ROM (read only memory) and a RAM (random access memory) are provided in the memory device 8, and the initial file set on the ROM has DP class as fixed data of the subscriber class. The data is set. When the initial setting key 9 is turned on, the initial setting is performed under the control of the central control unit 7, the ROM data is loaded to the RAM, and the system file in which the DP class subscriber data is set is stored in the RAM. Written in.

Next, the central controller 7 determines the presence / absence of the PB signal receiving section by detecting the identification information ID = 02 generated by the PB signal receiving section 6. When it is determined that the PB signal reception unit is present, this means that the PB signaling telephone set 2 is included in the system, so the central control unit 7 rewrites all subscriber data in the RAM to the PB class. . On the other hand, when it is determined that there is no PB signal receiving unit, the data in the RAM is not rewritten because the PB signal type telephone is not included in the system.

This completes the creation of the system file in the memory device 8. In other words, in the system, if PB signaling telephones and DP signaling telephones coexist,
A system file capable of performing PB signaling call processing is created with subscriber class data.

After the system file is set in this way, the subscriber class is determined by the method of the present invention as shown in FIG.

In the system shown in FIG. 2, when a call is made from the DP signal type telephone set 1, the subscriber circuit 3 connected to the telephone set 1 detects this and the central control unit 7 switches the circuit. The connection device 5 is controlled to set a path connecting the subscriber circuit 3 and the PB signal receiving unit 6.

Next, when the subscriber dials from the telephone 1, the subscriber circuit 3 detects the DP signal. Based on the dial information from the subscriber circuit 3 having the identification information ID = 01, the central control unit 7 determines that the telephone 1 is in the DP class by the first number and controls the circuit switching connection unit 5. Open the path.

After that, the central control unit 7 continues to receive the second and lower digits of the dial information and performs a normal exchange process using the set system file. In this case, since the class determination has already been performed, the exchange process can be performed by the PB class system file.

Further, when a call is made from the PB signaling telephone set 2, the subscriber circuit 4 connected to the telephone set 2 detects this, and the central control unit controls the circuit switching connection unit 5 to make the subscriber circuit. 4 sets a path connecting the PB signal receiving unit 6 and the PB signal receiving unit 6.

Next, when the subscriber dials from the telephone 2, the PB signal receiving unit 6 detects the PB signal. The central control unit 7 determines from the dial information from the PB signal receiving unit 6 having the identification information ID = 02 that the telephone 2 is not in the DP class, that is, in the PB class, by the first numeral. In this case, the path continues to be connected, and the PB signal receiving unit 6 detects the second digit and below of the PB signal. After that, the central control unit 7 continues to receive the second and lower digits of the dial information, and performs the normal exchange process according to the set system file. In this case, since the PB class system file is set, the PB signaling system exchange process can be performed.

As described above, according to the method of the present invention, the subscriber data is rewritten by determining the presence of the PB signal receiving unit (Fig. 3 (a)), the DP
In the case of a terminal, each step of connection between the subscriber circuit and the PB signal receiving section in the exchange (Fig. 2) and subscriber class determination by detection of dial information (Figs. 4 (b), (c)) is included. I'm out. As a result of lacking these steps in the conventional method, when the initial data is the DP class, it is necessary to reset the subscriber class in the system file as the PB class for each terminal to which the PB receiver is connected. Then there is no need for that.

〔The invention's effect〕

As described above, according to the method of the present invention, at the time of initial setting, the subscriber class data is automatically created, and when the DP signal terminal and the PB signal terminal are mixed, the subscriber class data is Is automatically identified.

According to the method of the present invention, it is not necessary to set the subscriber class data for each terminal at the time of system startup, so that the system test can be simplified and the construction period can be shortened.
