DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a multifunction terminal control method for controlling a music terminal from a multifunctional multifunction terminal.

(Prior art and its problems) In the conventional combined and asthmatic control system, control information is transmitted through the central + TT control device of the exchange, and the main function of the exchange is a multi-function control program of the terminal. And the concentrated η1j with data was adopted.

An example of a conventional multifunction terminal WtlJ control method will be described with reference to FIG. FIG. 1 shows a functional block 1g showing a conventional example.

In Figure 1, terminals A and B are of the same type @10
Telephone device 10 for voice system processing centered on telephone device
1. This telephone device 101 is controlled to record and reproduce voices; It includes an interface device It105'C that connects to the exchange 120 via an interface.

The communication line 1.10 is connected to the 04 terminal device 100 and includes a communication information path 111 and a terminal device 1 for transmitting received voice and data in digital codes of, for example, 64#-bpg.
For example, 1θ slope bp≦ between 00 and the exchange 120.

a control information path 11 that transmits control information in digital codes;
2 are time-division multiplexed to connect each terminal 100 and the exchange 120. The exchange 120 is a time division switch (
TDSW) 121, a central control unit (CC) 122 that controls the operation of the entire exchange together with this switch 121,
A main memory (MM) 123 having programs and data for operating this central control unit 122, and a terminal device 1
and an interface device 124 for interconnection with the 00.

Here, the answering function of the terminal 100-A will be explained as an example. When the terminal 100-A receives an incoming call from the telephone device 101-B of the terminal 10 (1-B), the terminal 100-A
is connected to the communication information path 111 by the interface unit 105-A.

Next, an embodiment of the present invention will be described with reference to the flowchart of FIG. 4 and FIG. 3 together with an example of the operating procedure when Ushin Kinuta is at home. FIG. 4 is a flowchart showing an example of the operating procedure in FIG. 3. First, the terminal 200-A is set for automatic response and automatic reception when the user is away from home (operation step (2)). Next, when a call arrives from terminal +100-B via exchange 220, terminal 200-A follows the conventional operating procedure to
22 via the connection information path 213 together with caller class information is received by the central processing unit 202 via the interface device 208 (operation step ■), and at the same time, the communication information path 211 between the terminals 200-A and B is received. and the control information path 212 is connected to the exchange 2200 and the time division switch 221
(operation step ■). Terminal 200
-A's central processing bag m1204 replies with an automatic response signal in response to the operation step ① of receiving an incoming call signal, while determining that the terminal 200-B has a CRT display device from the received caller class information -,=h. The weaving central processing unit 202 is connected to the interface device 208゜lfi! I information path 212. The interface device 224 sends a terminal control request signal to the central processing unit of the terminal 200-B via the time division switch 221 (operation step ①), and makes the terminal 200-H prepare to receive the CRT display device. When the terminal 200-A receives a reception ready signal from the terminal 200-B (m operation step ■), the central processing unit 202 of the terminal 200-A
This is the message that controls the device 204 and is stored when answering the answering machine: ``IA, Overseas Yamanaka, please make the following selections.''

Voice messages are sent via the keypad, written messages are sent via the keypad, and only records of telephone calls are sent via the keypad. ] to the interface device 2082 communication information path 211° interface device t224. The terminal 20 via the time division switch 221
Send to 0-B (operation step ■) [2.
Characters are displayed on the CRT display device of B. Operation information from the electric keyboard of the terminal 200-B according to this character display, such as key country information, is transmitted to the central processing unit 20 of the terminal M2O0-A.
2 is a time division switch 221. Interface device 224
．． Control information path 212. Receive via the interface device 208 (operation step ■). Central processing bag ft 20
When 2 receives the information of the key country and identifies the reception of a voice message, it sends a message to the transmission path from the playback circuit of the voice recording device 203 saying, ``When the chime has finished sounding, please send me a message.'' Then, the chime sound is emitted. At the same time, the recording circuit is connected to the receiving path to prepare for recording (step 4). When the chime has a predetermined length and the recording preparation is completed, the chime sound stops and the sound from the receiving path is recorded in the sound recording device 203 (operation step (2)).

Upon completion of the message, a disconnection signal is sent from the terminal 200-B to the central controller 222 of the exchange 220. Interface device 1224. Connection information path 213. The terminal [200-A central processing @, 92
02 (operation step 0), and the terminal 200-A
is restored (operation step O).

In this way, the interface device 208 connects the communication information path 211 of the communication line 210 according to instructions from the central processing unit 202.
It has the function of switching and connecting to the telephone device 201 when transmitting and receiving voice, and to the storage device 204 via the central processing unit 202 when transmitting and receiving data. A port for transmitting/receiving state control information to and from the exchange 220, and a port for transmitting/receiving connection control information for the exchange 220 are provided, respectively.

Further, when the key l is operated in operation step (2), the central processing unit 202 of the terminal 200-A receives the key country information and sends the message "Please send a message" from the storage unit R204.
Send an additional message to the CRT of terminal 200-H.
Characters are displayed on the display device, and the returned message is then recorded in the absentee data storage section in the storage device 204.

In the above embodiment, the explanation is based on the premise that the voice recording device is connected to a telephone device to record and play back analog voice, but it may also be a digital recording device that absorbs digital codes transmitted to a communication line. The internal configuration of the terminal is not limited to the above description, as in some cases, a separate means is required for reproduction, but the storage section of the storage device may be used.

In this way, when terminals are connected, the central processing units within the terminals exchange information with each other, so the conventional Iso 11me service for automatic transmission and reception between data terminals is expanded and included, and the exchange terminal This makes it possible to add a unique service function unique to the terminal, which is independent of the services provided to the terminal, which can be useful for improving services for terminal users.

(Effects of the Invention) As explained above, according to the present invention, when one terminal is connected to another terminal via a time division switch of an exchange, the central processing unit of each terminal By providing a control information path that directly sends and receives control information as a transfer path via a time-division switch, separate from the 1V signal path that sends and receives voice and data, switching load can be reduced due to the diversification of terminals. The effect of reduction can be obtained.
