Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to an integrated voice/data exchange system configured to exchange and communicate both voice and data.

[Technical Background of the Invention] With the recent progress in office automation, it has become possible to connect not only voice terminals such as multi-function telephones but also various data terminals to digital exchanges to communicate both voice and data. An integrated voice/data exchange system has been developed.

In such an integrated voice/data exchange system, in order to connect various data terminals to the digital exchange, a data service unit (hereinafter abbreviated as DSU) is required as a dedicated adapter between the data terminal and the digital exchange. become.

FIG. 6 is a block diagram showing the conventional configuration of this type of voice/data integrated switching system. The digital exchange 1 includes a multifunction telephone (hereinafter abbreviated as EKT) as a voice terminal. 3a and 3b are connected to a line 2a.

The DSUs 4a and 4b are connected to respective independent connection ports via lines 2c and 2d. Data terminals (DTE) 5a and 5b each having a standard interface (R3-232C interface) are connected to the DSLJs 4a and 4b via R3-232C cables 6a and 6b.

Of these, the EKTs 3a and 3b as audio terminals have a disconnect key 7, a call key 8. The DSUs 4a and 4b are equipped with a dial keypad 9, a plurality of function keys 10 that can set arbitrary functions, and the DSUs 4a and 4b have a disconnect key 111 and a call key 12. Dial keypad 13, multiple function keys 142 to which arbitrary functions can be set; speaker 15 for generating ringtones and confirmation sounds when operating various keys; Various states included in the connection procedure (dialable, calling, 2 communications in progress).

EKT3a, 3b and DSLI4a, 4
b are housed in separate housings.

Here, the operation when making a call from the DSU 4a will be explained.

First, when the calling key 12 of the calling DSU 4a is pressed, the "dialable" light-emitting display 16 lights up.

After confirming this, the number of the other party's DSU is input using the dial key hat 13. At this time, if the other party's DSU is vacant, the "calling" light-emitting display 16 lights up, indicating that the other party's DSLI is being called. On the other hand, in the other party's DSU, a ring tone is generated by the speaker 15. Therefore, on the other party's DSU, either the "start data communication (call)" key 10 is pressed or the terminal ready signal ER (on when the terminal is ready) is monitored and an automatic response is made to respond automatically. The light-emitting indicator 16 lights up and data communication is started.When restoring the data, either one of them presses the disconnect key 11, and the light-emitting indicator 1 that is "in communication" is switched off.
6 goes out, and the communication path for data communication is cut off.

On the other hand, voice communication is possible through a connection procedure similar to that of a regular telephone. Therefore, EKT3a, 3b and DS
By placing U4a and 4b close together, EKT
Data communication between data terminals becomes possible while making a phone call using 3a and 3b.

[Problems in the background art] However, in the voice/data integrated switching system as described above, the EKT and DSU each have a dial keypad, function key, etc. with the same function, so from the perspective of the entire system, this part is extremely redundant. Furthermore, since the EKT and DSU are housed in separate housings, there is a waste of storage space. Therefore,
There are problems in that the cost of the entire system increases and the storage space also increases.

[Object of the Invention] It is an object of the present invention to eliminate the above-mentioned problems and provide an integrated voice/data switching system with less redundancy in terms of cost and space.

[Summary of the Invention] The present invention provides a first means for setting at least a data communication start function and a data communication end function necessary for data communication of the data service unit on a key of a telephone; a second means for associating and storing connection port numbers between these multi-function telephones and the digital exchange of the data service unit; and third means for forming or disconnecting a communication path between the functional telephone and the data service unit of the same set and the digital exchange by referring to the memory contents of the second means, the telephone By configuring the control to be performed by the following, the above object is achieved.

[Embodiment of the Invention] FIG. 1 is a block diagram of essential parts showing an embodiment of the present invention, in which a DSU 4 from which a plurality of function keys, a dial keypad, and a speaker for generating a ring tone are removed connects the line 2b. via, EKT3 via line 2a and also DSLJ4
are connected to respective dedicated connection ports of the digital exchange 1 via lines 2b.

Here, the connection port number of the EKT3 and the connection port number of the DSU4 are registered in the exchange 1 in correspondence with each other as a pair of port numbers, with the corresponding EKT3 and DSU4 as one set.

This port number is registered by the installation/maintenance data input operation when the EXT3 and DSU4 are installed.

That is, the maintenance data input terminal is connected via the R8-232C standard interface provided in the exchange 1. And from this terminal type the command “
The 'EKT maintenance program' is transferred to the exchanger 1 from a floppy disk (not shown) which is an external backup memory.
into system memory (not shown) within the system. next,
Enter the boat number to which the EKT3 is connected, and roughly press two of the 10 function keys on the EKT3.
Register the functions ``Start data communication'' and ``End data communication.'' Furthermore, in addition to the item for starting data communication, the port number to which the EKT 3 and the corresponding DSU 4 are connected is input.

Through this series of operations, the corresponding EKT3 and DS
The connection port numbers PN of U4 are registered as a pair in the port number correspondence table (PN correspondence table) of the exchange 1. That is, as shown in Figure 2, the address corresponding to the connection port number PN (E) of EKT3 has the EK
Connection port number PN of DSU4 paired with T3
(D> is registered, and the connection port number P of DSU4 is
The connection port number PN(E) of the EKT3 paired with the DSU4 is registered in the address corresponding to N=7-(D>.

Further, functions that replace the cutoff key and call key deleted from the DSU 4 are set to two keys among the function keys 10 of the EKT 3.

Next, the operation of the exchange 1 will be explained.

This switch 1 has a boat number PN corresponding to the channel connected to the switch such as EKT3 or DStJ4.
and a directory number DN corresponding to a telephone number, and these operating states transition based on hardware input and logical input. FIG. 3 shows an operational state transition diagram based on the port number PN of the EKT4. Here, it consists of four operating states that are a combination of the EKT3's id l e/busy state and the DSU4 (7) id l e/busy state. The 1dle state is a state in which the terminal (EKT, DSU>) is free and can make and receive calls.
KT, DSU> are in use.

In FIG. 3, DSN means a key operation to start data communication, DR3 means a key operation to end data communication, SDN means a key operation to initiate a voice call, and RLS means a key operation to end a voice call. By operating these keys, the operating state based on the port number PN (hereinafter referred to as the operating state at the PN level, referred to as the PN state) changes to four states indicated by r00J to "10".

On the other hand, the state transition diagram of the operating state based on the directory number DN (hereinafter referred to as DN-level operating state, DN state) is not particularly shown, but it shows "Idle", "Waiting to dial", "Ringing", "'Talking" It consists of operating states such as "busy" and "incoming call", and the operating state changes based on the logical human power provided by PN-level actions (created by PN-level actions based on hard input). .

FIGS. 4 and 5 show how the boat number PN and the directory number DN are associated with each other with numbers .about.■. If the port number @PN and the directory number DN are associated according to ■ to ■ below, linkage is established. In addition, in Fig. 4, ES-PN is the port number of the calling side EKT, and ES-PN is the port number of the calling side EKT.
DN is the directory number of the calling EKT, DS-PN is the port number of the calling DSU, DS-DN is the calling DSU
The directory number, ED-DN and DD-DN indicate the port number of the EKDSU on the called side.

Next, EKT3 and DSU4 both i d I e (7
) state (PN state = "00'), the operation will be explained by taking as an example the case where the "Start data communication" key is pressed. First, when the exchange 1 receives the key information of the hard input "data communication start", it transitions the PN state from "00" to "01", and also changes the PN state from "00" to "01", as shown in FIG.
The N correspondence table is searched to find the port number P N and directory number DN of the corresponding DSLI 4, and the linkage shown in FIG. 4 is established. The logic input "data communication start" created at the PN level based on the hard input is received at the DN level of the DSU. This logic input causes the DN state to transition from "idle" to "dial waiting state" at the DN level, and also performs processing to send a dial tone to the EKT3 in accordance with the above-mentioned response.The sending of the dial tone is confirmed. If so,
Use the dial keypad 9 of the EKT3 to select the other party's DSU.
Dial in the number. This dial input is input as a logical input to the DN level of the DSU through the linkage described above. Then, when the DSU DN level receives the "dial number" as a logical input, it analyzes the other party's incoming call, and if the other party is "vacant", it sends the call to the calling side EKT4 via the communication path (■). At the same time, it sends a ring tone and sends an "incoming call" command to the called DSU. Also, based on the PN of the DSU on the receiving side, the PN correspondence table shown in FIG. 2 is searched, the port number @PN of the corresponding EKT is found, and a ring tone is sent to the EKT on the receiving side based on the linkage (2). The terminating DSU receives the “incoming call”
Upon receiving the command, it sends an incoming call indication signal to the data terminal via the R8-232C interface. Here, there are the following two response methods for the DSU on the called side.

One of them is an automatic response method, which monitors the terminal ready signal ER after sending an incoming call indication signal to the data terminal, and
If R is turned on, send the “‘Answer incoming call’ command to switch 1.
The other method is a manual response method, in which by pressing the "Start Data Communication" key on the EKT on the called side, a response is sent to the DSLI level as an incoming call response command based on the linkage described in (■) above. It is something to do.

Regardless of this difference between manual and automated responses, “
When the "Incoming call response" command is input, switch 1
Sends a “communication enabled” command to U, changes the status of both DSLIs to communication, and connects the EKT3 connection port and DSU.
The linkages of ■ and ■ with the connection boat No. 4 are released, the EKT3 is placed in the 1dle state, and the data communication channel is turned on. In this way, data communication between both DSUs becomes possible, and EKT3 becomes idle. Therefore, it is also possible to make voice calls using EKT3.

As explained above, according to this embodiment, the integrated EK
By using multiple function keys on the EKT to connect the T and DSU to the exchange, simultaneous voice and data communication is possible without adding a simultaneous voice and data transmission circuit. . Another advantage is that simultaneous voice and data communication can be easily achieved by simply attaching a DSU to an already installed EKT. Furthermore, since the data communication connection procedure uses the same sequence as the voice connection procedure, there is the advantage that a data communication path can be set up using the same operations as when making a telephone call.

Note that the DSU may be configured to be housed within the housing of the EKT and integrated with the EKT. In this case, the DSU can be stored, for example, in a cord storage section attached to the bottom plate of the EKT. Further, the DSU may be configured to be housed within the EKT mounting table. By integrating the DSU and EKT in this way, the installation space can be significantly reduced.

[Effects of the Invention] As explained above, the present invention uses the EKT key in place of the key required by the DSU during data communication, so redundant parts are largely deleted. . Therefore, the cost of the entire system can be significantly reduced, and the storage space can also be significantly reduced.
