DESCRIPTION:

BRIEF SUMMARY
TECHNICAL FIELD

This invention relates to telephone terminals, such as speech terminals of a financial dealing speech system used for financial dealing in financial institutions of banks and security companies and the like, speech terminals for dealing precious metals, reception terminals of taxi companies and transportation companies and the like, emergency speech terminals for holiday bank accounting, or telephone used in ordinary offices, and a telephone exchange system accommodating such terminals.


BACKGROUND OF THE INVENTION

The conventional telephone terminals used in the telephone exchange system or the dealing speech system have been used exclusively for speech functions. When a personal computer is used in such situation, the personal computer must be placed on a different space of the desk from that of telephone terminals. Therefore, the space on the desk become narrower to place other things. A concept of, so called, computer telephony has been proposed, which has a personal computer provided with a telephone function so as to solve such problem of desk space to place the personal computer and the telephone terminal.
Also, of a touch panel type, a multi-function telephone terminal is provided with a display and a touch panel screen displayed on the display. On the touch panel screen of this telephone terminal, ten-key (dial buttons), auto-dial keys, function keys providing special services, and the like are displayed.
In addition, a multi-function telephone terminal having a pagination function includes a monochrome display, and the status of the line in the telephone terminal has been displayed by changing the frame color of a line key displayed on the touch panel screen of the monochrome display, reversing the line key on the screen, flickering the line key on the screen or combining such the changing reversing and flickering.
It is noted that the prior art concerning the invention is described in Japanese Patent specification Laid-open sho57(1982)-188167, sho60 (1985)-116259, hei4(1992)-227363, and the U.S. Pat. No. 4,823,108, U.S. Pat. No. 5,001,710 U.S. Pat. No. 5,003,577, and a journal "Nikkei Electronics" on Feb. 14, 1994(No.601) pp115 to 127.
However, the conventional telephone terminal described above has a problem in the response with reference to the telephone exchange connection. It is difficult to employ such conventional telephone terminals in the telephone exchange system, for example, a dealing speech system to request an instantaneous dealings and a high line-catching speed.
When the transmission of an outgoing call and the reception of an incoming call of the telephone terminal are controlled by a control package (PC board) of a personal computer, an operation of the transmission and reception processing with respect to such control is executed through an operating system of the PC board, so it is difficult to operate the cyclic programs of the PC board and the telephone function. Also, when a disc accessing is carried out in the PC board, an application program is waiting, thereby consuming a long time operation for a process of a speech connection of the telephone.
The telephone exchange system necessitates a 24 hour running operation. However, the operating system (OS) of the PC board has a problem in reliability, because, when the operating system operates running for a long time, it may become locked.
Additionally, the conventional multi-function telephone terminal having the pagination key function displays the indication of the line status on the screen of the monochrome display. Accordingly, as there is a limit in the number of the indication of the recognizable status, and when the monochrome display displays the indication of the line kind on the screen, there is another problem of cancelling the number of characters of the line name with reference to the line kind on the screen.
This invention has been made considering such problems mentioned above of the prior art, and it is an object of this invention to provide a telephone terminal enabling to deal an ordinary
