DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a data management system for a telephone call station in a dealing telephone system used for conducting financial transactions in financial institutions such as banks and securities companies.

[0002]

2. Description of the Related Art In a conventional dealing telephone system, two methods are used for registering telephone station data, one of which is to directly register in a telephone. This was a method in which the units were shifted to the one-by-one program mode and registered manually.

[0003] The second is a system in which the line control device is fully digitized up to the terminal. For example, an ISDN is provided between the communication terminal and the line and between the office data management device and the line.
A system configured with a basic interface, a workstation and a terminal adapter are provided as a station data management device, and the intercom side is provided with hardware and communication software for B channel communication of the ISDN basic interface. The registered calling station data calls the designated calling station by inputting a command to the station data management device, downloads the data using the B channel as a calling channel, and also executes the command or the scheduled upload to the calling station in the workstation. It was a method of updating the station data.

[0004]

However, in the method of directly registering station data in the above-mentioned prior art in the call stand, the construction or maintenance person must move and register one by one, and the call must be made. There is a problem that it takes a lot of time in places where the number is large.

[0005] Further, since there is no data backup means, it is necessary to separately record the registered station data contents on a sheet, which is troublesome. Since registration is performed by inputting data, downtime is prolonged and service is reduced.

In addition, upon new delivery, station data is registered after the installation of the call stand is completed, so station data cannot be created in advance, and there has been a problem that it is difficult to deal with properties with short delivery times.

[0007] On the other hand, the download method based on full digitalization increases the price due to the digitization of both the line circuit of the line control device and the communication terminal, and also requires expensive workstations and terminal adapters. In particular, in the case of small and medium-sized systems, there is a problem in that the unit price per call terminal increases and the price tolerance decreases. Also,
Remote maintenance was not supported and there was a problem in terms of service to users.

The present invention is to solve the above-mentioned problem. In a pagination type call stand or the like which can display a accommodated line name on a display device corresponding to a line key and can accommodate many lines by switching pages. It is another object of the present invention to provide a communication station data management system which can be easily registered at a low cost.

[0009]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention relates to a central processing unit of a line control device.
