Abstract

PURPOSE:To facilitate the identification of an incoming call of voice and data communication by making the tone color of an incoming tone ringer for voice communication different from that of an incoming tone rinber for data communication. CONSTITUTION:When a call is given from an EKT 11d of a key telephone EKT-integrated type data interface unit DIU 29b to an EKT 11c of an EKT- integrated DIU 29a, a central control circuit CC 5 controls a digital talking circuit TSW 3 to close a channel 43 thereby applying a voice talking tone ringer from a generating circuit 37 to a speaker of the DIU 29a. When a call is given to a DIU 13c of the DIU 29a, a CC 5 controls a TSW 3 to close the channel 45 and the call is fed to a speaker of the data communication tone ringer DIU 29a from a generating circuit 41. Thus, the tone color of the tone ringer for the voice talking and data communication differs.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a voice data integrated exchange system in which the timbre of a tone ringer at the time of incoming call is made different between voice call and data communication.

[Technical background of the invention]

An example of a conventional voice data integration switch is shown in FIG. The voice data integrated exchange 1 includes a digital communication circuit (TSW) 3, a central control circuit (CG) 5, key telephone line circuits (ELC) 7a, 7b...
and line circuit for data interface unit (DL
C) Contains 9a, 9b...

ELC7a and 7b each have key telephone (EKT) 11
a, 11b are connected, and DLC9a.

9b each has a data interface unit (DIU).
Data terminal equipment (DTE) 15 via 13a, 13b
a and 15b are connected.

FIG. 4 is a circuit diagram showing the configuration of the DIL 113a. D
TE interface circuit (DTE, INF>17 is DT
For example, R8-232
0 standard interface.

Line interface circuit (LINE I'NF) 1
Reference numeral 9 provides an interface with the digital exchange 1 via the DLC 9a. A control circuit (CONT) 21 includes a microcomputer and a memory, and this DIU 13
a Performs overall control.

The key force detection circuit (KEY>23 detects key force on dial buttons, function keys, etc.).The display circuit (LED) 25 blinks display elements such as light emitting diodes as appropriate.The sounder (SOUND) circuit 27 detects incoming calls. Generates a tone when it occurs.

Voice communication and data communication using such voice data integrated exchange 1 are as follows.

For example, when making a voice call between EKTl 1 a and EKTl l b, from EKTl 1 a to E'KT11.
When dial b is input, CC5 makes the tone generator (not shown) of EKTllb ring.

When the called party of EKTllb picks up the handset, CC5 connects the line and a call can be made between EKTI 1 a and EKTllb.

On the other hand, when data communication is performed between the DTE 15a and the DTE 15b, the process is as follows.

When performing data communication between the DTEs 15a and 15b, it is first necessary to connect a communication path from the corresponding DIU, and now we will explain the connection from the DItJ 13a to the DIU 13b. When the data transmission key assigned to the DIU 13a is pressed, the transmission request is sent to the DLC through the cable.
9a, [) CC5 via the signal line from LC9a.
will be communicated to.

When the CC 5 recognizes that the outgoing request is from the DIU 13a, it sends the outgoing request in the completely opposite direction to the route through which the outgoing request was transmitted.
An acceptance signal is returned to the DILJ 13a.

When the DIU 13a receives this acceptance signal, it lights up an LED 25 (FIG. 4) labeled, for example, "Dialable" to prompt the operator to input a dial number for selecting a communication partner. Operator is D
When dialing is performed to select ILJ 13b, ie, DTE 15b, these dials are sent to CC5 in exactly the same way as described above. When all digits on the dial have been received,
The CC5 checks whether the DIL 113b is free or in use, and if the DIL 113b is free, sends an incoming call to the [)ItJ 13b, and sends a call to the DIU 13a.

When the DIU 13b receives an incoming signal, the DIU 13b
The sounder 27 (Fig. 4) installed inside is made to sound,
Notify the operator of the incoming call. When the originating DIU 13a receives the above-mentioned calling signal, it lights up, for example, the "calling" LED 25 (FIG. 4) in the same way as described above. D.I.
As mentioned above, between U13b and DTE15b, for example, R8
-2320, and when a call arrives at the DIL 113b, the DIU 13b checks the status of the DTE 15b connected to itself. R
If the 8-2320 signal line indicates that the DTE 15b is powered on and ready for communication, the DIU 13b will respond to the incoming call if the IU 13b is set to automatic response mode. Return to CC5. In the case of the DIU 13b manual response mode, the sounder continues to sound until the operator responds.

When the DIU 13b responds, the CC5 sends the DIL 113a,
Furthermore, it sends a “communication possible” signal to D1tJ13b and DL
The communication path between C9a and C9b is closed by TSW3. D.I.
U13a and 13b are connected to the corresponding LED by the communication enable signal.
25 to inform the operator that data transmission is now possible. From then on DTE15a and DTE15b
Communication takes place between.

As described above, in the conventional voice data integrated exchange 1, the IUs 13a and 13b are used as described above to connect the DTEs 15a and 1'5b, and the DIU 13
a, 13b had dial buttons, other function keys, and a sounder, and could form a data call completely independently of EKTlla, 11b. However, when performing simultaneous voice and data communication using the IUs 13a and 13b as described above, the EK
Tlla, 11b and DIL for further data communication
113a and 13b had to be prepared on the desk, which resulted in a poor space factor and was expensive. For these reasons, E)<T integrated type D1tJ was devised.

FIG. 5 is a block diagram of such an EKT-integrated DIU 29. As shown in the figure, this EKT-integrated DTU 29 has a DIU circuit 13 mounted inside or at the bottom of the EKTll. This DIL1 circuit 13 is the DILJ circuit shown in FIG.
The key human power detection circuit 239 and the display circuit 25 are deleted from the EKTl 1, and the EKTl 1 is
The DIU circuit 13 is also connected to the digital exchange via the DLC by a cable 33 and to the DTE by a standard interface 35 such as an R8-2320 cable.

In this type of EKT integrated DIIJ, as mentioned above, D
Since the IIJ circuit 13 is mounted inside the EKTll or attached to the bottom of the EKTll, the desk space is the same as that of a conventional EKT, and costs are also reduced by using the same housing. There is an advantage that it can be done.

[Problems with background technology]

However, in order to exchange data using this EKT-integrated DIU, it is necessary to first close the transmission channel in the sequence of outgoing calls, dialing, and answering as described above. , the same e-mail is used for incoming calls for data communications and voice calls.
There was a problem in that tone ringers of the same tone were emitted from the KT, and the operator had to look at the display each time to distinguish between them, making the operation cumbersome.
