It consists of a melody part 307 and a paging matching part 308.

2 and 3, the power supply unit 301 supplies power required for the operation of the common resource LAN module 300 for building a distributed structured switched network according to the present invention. The controller 302 generally controls operations of each component in the common resource LAN module 300 for constructing a distributed structured switched network according to the present invention. The controller 302 is responsible for signaling and control of the common resource LAN module 300 according to the present invention, and controls a process for using a resource and a process of transmitting the resource to the LAN network. The memory unit 303 stores control programs and data necessary for the operation of the common resource LAN module 300 for establishing a distributed structured switched network according to the present invention. The LAN interface unit 304 interfaces mutual data between the common resource LAN module 300 and a data network connected through the LAN. That is, the LAN interface unit 304 transmits the common resource data generated by the common resource LAN module 300 to the distributed structured network in the form of TCP / IP, and interfaces the data transmitted from the distributed structured network. The DTMF unit 304 performs the functions of the DTMF receiver and the DTMF transmitter, respectively, under the control of the controller 302. That is, the DTMF unit 305 generates a DTMF signal under the control of the controller 302, transmits the DTMF signal to the switching network through the LAN interface unit 304, and receives the DTMF signal transmitted from the switching network through the LAN interface unit 304. The R2MFC unit 306 processes the R2MFC signal under the control of the control unit 302. The tone / melody unit 307 generates a tone and a melody under the control of the controller 302 and transmits it to the external melody device 310. The paging matching unit 308 performs a paging function through the external paging equipment 320 under the control of the controller 302.

The operations of the common resource LAN module for building a distributed structured switched network according to an embodiment of the present invention will be described with reference to FIGS. 2 and 3. The common resource LAN module 300 provides various signals such as DTMF signal, R2 signal and tone signal through basic resources necessary for exchange service, that is, DTMF / R2 transceiver and tone generator. That is, when the common resource LAN module 300 receives a request for such a resource from a subscriber module or a trunk line module, the common resource LAN module 300 is allocated by the service LAN module 220 to provide a service for the resource while interworking with each subscriber module or trunk line module through TCP / IP. do. When an event occurs in each subscriber module or trunk line module, the module transmits a control packet to the conference module requesting the use of common resources. The control packet includes information on the IP address of each module and the requirements of the common resource. The common resource LAN module 300 sets up a virtual speech path with each member of the counterpart LAN module conference by using the information included in the control packet and drives the internal conference call processing unit. Provide service.

Meanwhile, the common resource LAN module 300 terminates by receiving a release signal from the member when the common resource ends. In addition, in case of R2 signaling, the common resource LAN module 300 terminates allocation of the common resource by transmitting an end signal to the counterpart.

The common resource LAN module 300 according to the present invention separates and manages the use of common resources into fixed and allocated types. The fixed common resources are DTMF transmission function, melody and tone generation function, and the allocated common resources are DTMF reception function, R2MFC function and paging function.

The fixed common resource is data of a common resource which is supplied to the subscriber module or the trunk line module. Therefore, the common resource LAN module 300 provides a service in a 1: N multicasting manner in which data generated from one resource is distributed and transmitted simultaneously to several IP addresses by fixing common resources simultaneously used by several counterpart modules.

On the other hand, the allocation-type common resource is to provide a common resource in a 1: 1 connection with the target subscriber module or trunk line module. Therefore, if there is a request for a common resource from the subscriber module or the CO line module, the common resource LAN module 300 allocates a corresponding resource and connects a 1: 1 virtual channel to serve.

The common resource LAN module 300 according to the present invention implements a function of compressing each common resource data to transmit / receive with a corresponding subscriber or trunk line module in order to process a common resource in real time. The common resource data thus processed is loaded on the LAN / WAN data network 200 in the form of TCP / IP in the LAN interface unit 304 and provided to the requested subscriber or trunk line module.

The external melody device 310 and the external paging device 320 are analog interfaces connected to the outside and connect music or paging speakers when necessary.

As described above, the present invention can implement a distributed structured switching scheme for each module unit instead of a conventional centralized control scheme by providing a common resource required in a switching network in one module. Therefore, the present invention is easy to install and expand in a distributed manner because the system can be connected freely via a LAN. In addition, the present invention has the advantage that the function can be separated without being dependent on the system because the common resource utilization process is made independently of each subscriber module or trunk line module. In addition, the present invention has the advantage that the capacity can be easily changed according to the requirements of the system customer since the capacity is determined according to the installation quantity of the common resource LAN module. In addition, the present invention can be implemented using a LAN in the connection of the external paging equipment or external melody device, etc., there is an advantage in that it is easy to install and maintain in position.
