Embodiment:

Dispatcher in the system running environment, this paper is that example is explained with the Coral dispatcher, the Coral dispatcher is the series digit stored-program control exchange that Israel Tadiran company produces, IP phone, this paper is example with the Coral IP phone, and the Coral IP phone is a IP phone that Israel Tadiran company produces.Between Coral dispatcher and the dispatching patcher, and communicating by letter between Coral dispatcher and the terminal phone finished by the APA agreement, APA is writing a Chinese character in simplified form of Application Processor Adapter, is the communication protocol interface between dispatch terminal and terminal phone and the dispatcher.

Below in conjunction with accompanying drawing embodiment of the present utility model is described further.

As shown in Figure 3, the touch-screen dispatching patcher comprises that dispatching patcher main frame 1, touch-screen display 2 and 3,4, two Coral IP phone 3,4 of two Coral IP phone utilize straight through cable to link to each other with dispatching patcher main frame 1, as the left and right handle of dispatching patcher; Touch-screen display 2 links to each other with dispatching patcher main frame 1 by the VGA connecting line, realizes Presentation Function, links to each other with dispatching patcher main frame 1 by USB connecting line or serial port connecting wire, realizes touch function.

The dispatching patcher main frame, as shown in Figure 2, form by three parts:

The interface board 5 of integrated POE switch is used for dispatching patcher networking demand;

Embedded main board 6104-1811CLDNA (B) is used to finish the function of dispatcher software;

Fan 7 is in order to finish the heat radiation of embedded main board;

Wherein link to each other by network connection, audio connecting cord, USB connecting line, serial port connecting wire and VGA connecting line between interface board 5 and the embedded main board 6.

The interface board 5 of integrated POE switch comprises following part:

Mixed-media network modules mixed-media 8 uses chip model RTL8305, realizes 4 port network switches, in order to the communication between the realization dispatching patcher internal components and the demand of whole dispatching patcher networking; Wherein 1 port links to each other with local area network (LAN), and 1 port links to each other with embedded main board, and 2 ports link to each other with two Coral IP phone by straight through cable.The embedded main board that has guaranteed two Coral IP phone and dispatching patcher inside all is among this local area network (LAN).

POE module 9, the POE module in the interface board is integrated PSE chip, model is LTC4258, has constituted the POE system by feeder ear equipment PSE and receiving end equipment PD.POE module in the interface board only comprises the power supply unit PSE end in the POE system, and PD equipment is the PSE load of accepting power supply, i.e. the client device of POE system, and the PD equipment in this POE system is the Coral IP phone.Power supply unit PSE chip only needs a straight through cable when linking to each other with powered device PD, just can reach the purpose to powered device PD power supply and network service.The PSE chip is power receiving equipment Coral IP phone power supply in the system by Ethernet in the native system, realizes the POE function of supplying power.Power supply unit PSE has functions such as detection, classification, guarantees only powered device PD to be powered, and power supply safety is reliable, and makes network layout succinctly convenient.

Power module 10 has two kinds of power supply input patterns of alternating current 220V and direct current 48V, in order to whole system is powered.Duplicate supply can use simultaneously, reaches the purpose of duplicate supply backup, also can independently use, and the switching between the duplicate supply does not influence dispatching patcher and normally moves.Input voltage is through the corresponding conversion of power-supply system, for whole system provides 5V, 3.3V and 1.8V direct voltage.

The signal that transmits in the straight through cable is: network signal and power supply signal.Wherein network signal transmits by 1,2,3,6 lines of straight through cable, in order to finish the network service of dispatching patcher main frame and Coral IP phone.The Coral IP phone is supported the POE function, belong to the power receiving equipment in the POE system, because the inner integrated network switch of dispatching patcher main frame with POE function, can power to the Coral IP phone by straight through cable, the power supply signal is that 4,5,7,8 lines by straight through cable transmit.

Operation principle of the present utility model: as shown in Figure 4, touch-screen dispatching patcher and Coral dispatcher are in the consolidated network, both are based on IP and finish information interaction, realized that promptly Coral IP phone, dispatching patcher main frame and Coral dispatcher by the purpose that IP intercoms mutually, finish corresponding scheduling feature.

Present embodiment touch-screen dispatching patcher is based on that the scheduling feature of Coral dispatcher realizes, communicate by letter with the Coral dispatcher by the APA agreement, control the Coral IP phone fully, scheduling feature such as realize conversation, reservation, switching, intrusion, intrusion, group's meeting, select to answer.The interface board of dispatching patcher is finished following function:

If certain one handle (Coral IP phone) free time of dispatching patcher host A, then this moment, the user can be by the clicking operation call scheduling system host B to touch-screen display, the embedded main board of dispatching patcher host A receives whole operation informations, and operation information is converted into the agreement of APA form, send to the Coral dispatcher by network, the content of this APA information is the handle of the handle call scheduling system host B of dispatching patcher host A.At this moment the Coral dispatcher will be controlled the handle of dispatching patcher host A, allows the handle of its call scheduling system host B.

Dispatching patcher can receive and resolve the APA information that the Coral dispatcher transmits in real time, obtain the phone information relevant with handle, thereby realization caller identification, make the user can learn the state information of Coral IP phone in real time, realize that touch-screen display shows the purpose of Coral IP phone current state in real time.This moment is if the handle of dispatching patcher host B has been answered this incoming call, the meeting of dispatching patcher host B sends APA information to the Coral dispatcher, this APA information is the incoming call that dispatching patcher host B handle is answered dispatching patcher host A handle, this moment, the Coral dispatcher can be controlled the conversation of two handles, and the Coral dispatcher can send the APA information that two handles are conversed to dispatching patcher host A and dispatching patcher host B respectively simultaneously.

In the middle of the process of conversation, can also realize reservation, recovery, switching, intrusion, toll breakdown, scheduling feature such as Three-Way Calling.

When either party on-hook of both call sides, the Coral dispatcher can send handle on-hook information to dispatching patcher host A and dispatching patcher host B, and then dispatching patcher host A and dispatching patcher host B stop conversation respectively, and show that the handle state is an idle condition.

This dispatching patcher can also realize not having acoustic monitoring, contraposition shows, night clothes, select to answer, preengage callback, telephone directory inquiry, handle scheduling features such as meeting, group's meeting, paging of chipping in, call the roll on the same group.
