Description

Method for managing IP address of ITM board using master board in PBX system}

The present invention relates to a method of controlling Internet access in a private exchange, and more particularly, to manage IP (Internet Protocol) addresses of a plurality of SIGate (Internet Gateway System) boards embedded in a private exchange, and to recognize the external Internet. It is a method to manage IP address of IT board using router master board in private exchange system that sets up a master board and routes incoming packets to SIGate boards embedded in private exchange.

Typically, the Internet connects numerous networks around the world, connecting many computers into a network. The Internet is able to transmit information between various networks by using a predetermined protocol (eg, TCP / IP) between networks, and is open and compatible with more and more users.

Due to the characteristics of the Internet, various communication services are being implemented. Among them, a service that transmits voice and data in real time using the Internet has been in the spotlight. An example of such a voice transmission service is an Internet phone service. .

In the private exchange that provides the Internet phone service, the routing function can be combined to provide a higher level of service. That is, the voice and data are transmitted in real time on the Internet as well as the packets moving on the local area network by the routing table. You can send and receive destinations.

It sets up a master board that operates the Internet access among the various ITM boards of the SIGate system to recognize the IP of the master board on the external internet, and the master board sends the packets coming into the SIGate system to the internal ITM boards and the internal ITM board. It can be used to send a packet of data to the outside Internet.

On the other hand, PBX is an abbreviation of Private Branch Exchange and means an internal branch exchange of a telephone network.

An internal exchange is an exchange which performs exchange connection between the extension telephones of the premises (local telephone line) telephones or between the extension telephones and the trunk lines (telephone telephone telephone lines) at workplaces such as government offices, companies, factories and hotels.

The branch exchange system is a revolving premises exchanger that performs all connections such as incoming / outgoing connections from trunk lines to stations, outgoing connections from stations to trunk lines, and interconnections between stations. After the change, it has evolved and developed into an electronic branch exchange (EPBX) of accumulated program control method using a microprocessor or IC memory.

The Electronic Branch Exchange (EPBX) has the ability to perform more than 100 different services, such as timed calls and simultaneous data transfer, and has become an indispensable device in the establishment of local area networks, as well as ISDN. .

There are two types of currency path methods: the spatial division currency path method and the time division currency path method. A digital PBX, which encodes and exchanges an audio signal (analog signal) in several forms of electric signals, is called a digital PBX.

Digital PBX connects OA devices such as PCs, word processors, and facsimile machines used in the premises to convert and multiply data and voice into digital signals so that multiple signals can be simultaneously transmitted and communicated on a single line (transmission path). .

Therefore, the digital PBX is a key device of the digital network, which is a more advanced means of communication, and occupies a very important position for effective LAN construction and ISDN construction.

Each ITM board in the existing SIGate system described above has an IP address, so that the connection to the external internet network is made separately.

In this case, all IP addresses of the embedded ITM boards need to be analyzed to recognize the SIGate system in the external internet network.

Accordingly, the present invention was devised to solve such problems, and an object of the present invention is to provide a method for managing IP addresses of all ITM boards embedded in a SIGate system in a master board to perform access to the external Internet. In providing.

In the present invention, a method of managing an IP address of an ITM board using a router master board in a private switch system according to the present invention is provided in the method of managing IP (IP) addresses of an ITM board of a private exchange. Initializing Ethernet connected to the exchange and initializing and setting network information of the private exchange; After setting, the routing table is set to be connected to an external network connected to the private exchange by setting one of the IT boards as a master board, and the other IT boards not set as the master board are slave boards. Setting a routing table to be connected to an internal network connected to the private exchange by setting to; And setting up to be connected with the internal network, and transmitting packet data to or receiving from the external network at the master board or the slave board.

Preferably, the network information includes an Internet Protocol (IP) address, a subnet mask, and a gateway address.

Preferably, in the master board or the slave board, transmitting the data packet to the external network or receiving the data packet from the external network may be performed through the master board when the slave board transmits the packet data to the external network. Routing to forward the packet data; And when the packet data is received from the external network, routing the packet data to be delivered to the corresponding slave board.

Hereinafter, the objects, features, and advantages of the present invention described above will be described in more detail with reference to the preferred embodiments of the present invention shown in the accompanying drawings.

A front view of the ITM board is shown in front. Hereinafter, a method of managing an IP address of an ITM board using a router master board in the private switching system of the present invention will be described in detail with reference to FIGS. 2 to 5. The applied ITM board stands for Internet Telephony Module, which is a Private Automatic Branch eXchange (PABX) trunk type H.232 VoIP gateway. The ITM board controls call connections between H.232 terminals (eg IP phones) connected via IP networks and subscribers connected via PABX, and performs PSTN / VoIP protocol conversion and 64K PCM / VoIP codec media conversion. The hardware configuration consists of RISC processor, memory, audio DSP and Ethernet controller and I / O port in the form of board inserted in the insertion slot. As shown in FIG. 3, the SIGate system is inserted from the front side and the front part is used for each channel. LED is installed and LAN port is installed at the rear side.

After initializing the Ethernet connected to the private exchange built-in SIGate 500 (step: S100), network information of the private exchange built-in SIGate 500 is set (step: S200).

Here, the network information includes an IP (Internet Protocol) address, a subnet mask, and a gateway address.

On the other hand, if the private exchange built-in SIGate 500 operator is required (step: S300), the network information can be reset.

After setting and initializing the setting, any one of the private exchange built-in SIGate 500 ITM boards is set as a master board, and a routing table is set to be connected to an external network connected to the private exchange built-in SIGate 500 (step). In step S500, the RTM board is set as a slave board, which is not set as the master board, to set a routing table to be connected to an internal network connected to the private exchange (step S500).

After establishing the connection to the internal network, the master board or the slave board transmits the packet data to the external network or receives from the external network (step: S600).

Here, (S600), if the slave board transmits the packet data to the external network (step: S610), routing to deliver the packet data through the master board (step: S620), When the packet data is received from the external network (step S630), the packet data is routed to be transmitted to the corresponding slave board (step S640).
