Abstract

PURPOSE:To attain ordering by a phone call even if no idle extension exists by ringing a bell of an extension telephone set when the absence of an idle extension is detected and an incoming call of personal computer communication is detected and a lighting a personal communication pause lamp. CONSTITUTION:When all extensions for personal communication 70(m+p) 70(m+l) are busy and a call of personal computer communication is received from an external line 10, a communication pause processing section 60 applies a communication pause request. When a communication pause reply returns from the caller side, a master equipment 20 rings the extension telephone sets 80(l)-80(m). Simultaneously, the personal computer communication pause lamp of the extension telephone sets 80(l)-80(m) is lighted. Thus, it is notified to the reply person of the extension telephone sets to be a reply for the personal communication pause.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a button telephone system having a personal computer communication unit.

[Prior Art] In a conventional button telephone system having a personal computer communication unit, when an extension line for personal computer communication in the system is occupied, if there is an incoming call for personal computer communication, the incoming personal computer communication is terminated. I had no choice but to cut it.

[Problem that the invention seeks to solve] However,
The conventional example described above has the disadvantage that the PC communication side that made the call cannot know the reason for the disconnection, making it difficult to deal with it.

[Means for Solving the Problems] According to the present invention, an extension detection means for detecting whether or not there is a vacant extension among the extensions for PC communication in the system, and a bell and a PC communication stop lamp are provided. an extension telephone having an extension telephone, a suspension request means for transmitting a communication suspension request to the calling PC when the extension detection means detects that there is no vacant extension when an incoming call for PC communication is detected; By providing a control means that rings the bell of the extension telephone and turns on the PC communication suspension lamp when a communication suspension response is received from the calling PC, even when there is no vacant extension for PC communication, the telephone You can contact me at

[Example] FIG. 1 shows a system configuration diagram of an embodiment of the present invention.

In Figure 1, 10 (1) to 10 (n) are external lines,
20 is the main device of the button telephone system, 30 is an extension management unit for PC communication, 40 is a connection monitoring unit, 50 (1) to 50 (l is a PC communication judgment processing unit, so (1) to 60 (l is communication suspension) Processing unit, 70 (1) to 70 (
m+p) is an extension, 80 (1) to 80 (m) is an extension telephone with a PC communication stop lamp, 90 (1)
90 (p) are personal computer communication adapters with attached telephones, and 100 (1) to 100 (P) are personal computers.

The main device 20 knows from the connection management section 40 which number of the PC communication adapter 90 or the extension 70 it is connected to. Based on this and the operational status, the PC communication extension management unit 30 can grasp the number of available PC communication extensions.

Computer communication is carried out between outside line and extension, between extension and extension,
Extensions 70 (m+1) to 70 (m+p) for PC communication
), when all p extensions are in use, if an incoming call for PC communication is received from the outside line IO, the PC communication cannot be performed. Therefore, the communication suspension processing unit 6
0 to issue a communication suspension request to the calling party. Here, the determination as to whether the calling party is communicating with a personal computer is made by the personal computer communication determination processing section 50.

In addition, extensions 70 (m+1) to 70 (
The same thing applies when (p-1) extension lines of (m+p) are in use and a call is made from the personal computer 100 on the remaining line to another personal computer 100.

When the extension line for personal computer communication is busy and the communication suspension processing unit 60 issues a communication suspension request to the calling party, when a communication suspension response is received from the calling party, the main device 20 transmits the extension telephone so (1 ) to ring the bell at 80 (m).

At the same time, the telephone extension 80 (1) to 80
Turn on the PC communication pause lamp (m). By doing so, the person answering the extension telephone is notified that the response is to suspend communication with the PC.

When one of the extension telephones [80(1) to 80(m)] answers, the main device 20 switches to that extension telephone and enables a call. The person answering the extension telephone informs the caller that the extension line for personal computer communication is blocked and urges the caller to take action.

[Other Embodiments] In the system configuration diagram of FIG. 1, the personal computer communication adapters 90(1) to 90(P) may be built into the main device 20, and the telephone attached to the adapter 90 may be omitted.

Then, communication suspension processing when PC communication is performed between an outside line and an extension line or between an extension line and an outside line is performed using the extension phone fi80 (
1) to 80 (m). That is, the personal computer communication suspension function of the above embodiment is a function that temporarily stops data communication between personal computers and makes a call using the telephone attached to the adapter 90. However, in this embodiment, this function is performed using extension telephones 80 (1) to 80 (m) of the key telephone system.

Furthermore, in addition to communication suspension processing, all processing using telephones in PC communication processing, such as manual PC communication calls (calls using telephones), can be performed using extension telephones 80(1) to 8.
0 (m) can also be used instead.

Therefore, the cost of the key telephone system can be reduced.

[Effects of the Invention] According to the present invention, even if there is an incoming call for PC communication when there are no available extensions for PC communication, the user can be contacted by telephone. If you want to, you can have the computer that made the call take appropriate action.

[Brief explanation of the drawing]

FIG. 1 is a block diagram of an embodiment of the present invention. 20 is the main device, 30 is the extension management unit for personal computer communication, 60 is
80 is an extension telephone, and 100 is a personal computer.

Claims (1)

[Scope of Claims] Extension detection means for detecting whether or not there is an unoccupied extension among the extensions for PC communication in the system, an extension telephone having a bell and a PC communication pause lamp, and an incoming call for PC communication. a suspension request means for transmitting a communication suspension request to the calling PC when detecting that there is no vacant extension by the extension detection means; and receiving a communication suspension response from the calling PC. The button telephone system is characterized in that it has a control means for ringing the bell of the extension telephone and lighting the PC communication suspension lamp.
