Description

The present invention relates to a dealing telephone system used for conducting financial transactions in financial institutions such as banks and securities companies.

[Conventional technology]

The dealing system is divided into a call system and an information system, and the information data display function is a function provided by the information system.In addition to the call system, a video source of multiple information data is provided. It is composed of a video switching system for inputting and outputting the selected video signal to the CRT of the talking stand, a CRT for displaying information system data prepared for each talking stand and a keyboard for selecting the video source.

[Problems to be solved by the invention]

In the above-mentioned conventional example, in order for the user to realize the display function of information system data, a large-scale video switching system must be installed and a CRT and a keyboard must be installed for each phone, which is suitable for users with small capacity. May be postponed due to problems such as high system price, space for installing machines, addition of construction cables, and reduction of work space of desks.

An object of the present invention is to provide a user having the above-mentioned problem with an information system data display function simply by using a communication system without introducing dedicated equipment.

[Means for solving the problem]

The above problem is that the video source of the information system data is input through the display signal conversion device to the line control device having the digital interface for the communication system from the digital trunk, and the display signal is transmitted to the communication stand using the communication channel. This is solved by transmitting and switching the display source of the touch screen provided on the common base surface for displaying the line key to the display signal of the information system data.

[Action]

Video signal switching is performed by the TSW of the line control device.
Since it can be done with (time-division switch), the video switching system can be deleted, and the construction cable up to the CRT is also unnecessary by using the communication channel. In addition, since the CRT can be used as a display for a call system, there is no need to install it for information systems, so the work space of the desk will not be reduced. Moreover, no dedicated equipment is required.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings.

In Fig. 1, LCU compatible with ISND interface
A plurality of DBs (communication consoles) are connected to the (line control device) via an ILC (I interface line circuit) with an S point interface. The switching network is connected by TRK (analog trunk) or ITC (I interface trunk). The video source signal shall be input from the ITC through the T point interface via VSIFU (Video Signal Interface Unit).

In Fig. 2, the board surface of DB1 is line key 2, line key display touch screen 3, TEN key 4, recovery button 5,
It is composed of a display screen switching button 6 and two handset 7 for communication are connected.

Normally, when making a call, when the line key is pressed or the line key on the touch screen is touched, the line key code is sent from the DB to the LCU through the D channel, and the LCU captures the corresponding trunk and connects the call channel. To do. TEN key dial information is also sent from the D channel, and a selection signal is sent from the trunk. The call is made using the B channel in response to the other party. To end the call, the restore button is pressed.

Since the call stand has two handsets and two call channels B1 and B2, two calls can be made at the same time. When one of the two B channels is vacant (in this embodiment,
B2 channel is fixed), as shown in Fig. 3, information system data can be displayed. Of the line keys corresponding to the ITC to which the video source is input, the line of the video source to be displayed When the key is pressed, the trunk is seized as in the case of a call, and the corresponding trunk is connected to the B channel through the TSW (time division switch).

In DB, AMI code (PSEUD
O TERNARY CODE) is converted to logic level and the transmission rate is converted, then the channel is separated into B1 and B2. In the case of a call, it is D / A converted by the CODEC FILTER, and the call is made by the handset through the NW (network), but by setting the display screen switching button on the DB board, the CH point is switched to the RA side and RA ( The rate-adapted display data is read by the CPU (central processing unit) through the USART (serial / parallel converter), refreshes the display data of DSPCNT (display control unit), and displays the line key display touch screen 3. Information system data can be displayed on.

In the present embodiment, the video source is converted into the display command format in VSIFU and sent out due to the restriction of the transmission speed of the B channel, and in the DB, the CPU once takes in the data and displays the display data corresponding to the command in DSPCNT. The method of setting is adopted. Further, when the display data is changed, it is possible to easily change the trunk connection because the trunk connection can be changed with one touch by pressing another line key.

[Effects of the Invention] According to the present invention, it is possible to realize a simple display of information system data using a communication system without introducing a dedicated facility, and therefore the system price is greatly reduced. it can.
