Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a private branch exchange device for transmitting control information between an operation console and a special service control processor in a private electronic branch exchange, such as a hotel electronic exchange.

In conventional private branch exchanges for hotels, the hotel service console and the hotel service control processor are always directly connected using a data bus, and the hotel service control processor is connected to the connection control processor that controls the exchange function. Generally, they were directly connected. In such exchanges, as the number of hotel service operation consoles increases, the number of physical data transmitting and receiving devices between the hotel service operation consoles and hotel service control processors increases, which impairs the economic efficiency of the entire exchange. . In addition, in such a switchboard, the hotel service operation console is completely separated from the switching section of the call transmission line, so if you want to add a call function to the operation console, you will have to independently install a device with that call function. There is a need to add additional components, which is economically disadvantageous.

The purpose of this invention is to solve these drawbacks,
That is, it is an object of the present invention to provide a private branch exchange device that can economically increase the number of special hotel service operation consoles and economically add a calling function to the operation consoles.

The private branch exchange device of the present invention houses one or more operation consoles (hotel service operation console) and a control processor dedicated to the console in a time division switch, and controls the processor dedicated to the console and the time division exchange switch. A bus is connected between the central control units via an interface device, and dial operations are performed from the control console to control the central control unit (processor for connection control) between the control console and the dedicated processor for hotel services (hotel service control processor). It is characterized by being connected via a time division switch to the base of the system, allowing mutual transmission of control information.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Conventional examples and embodiments of the present invention will be described below with reference to the drawings.

Figure 1 is a block diagram of a conventional private branch exchange for hotels, where STA is an extension telephone, TDSW is a time division switch, CPU is a main processor (central control unit) for connection control, and H/M CPU is a processor for hotel service control. , H/M CON is the hotel service operation console, H/M INT is the interface device between the hotel service control processor and the main processor for connection control, TRK is the central office line trunk, and C/O
indicates a central line. Here, as an example of a hotel service, control of a K-scheme central line call rate management service will be explained. In Figure 1, the extension telephone
When the STA makes a call to the central office line and captures the central trunk TRK, the connection control processor CPU collects information such as the accommodation location information of the extension telephone STA, the accommodation location information of the central office trunk TRK, and the dialed office line number information, etc. Data is sent to the hotel service control processor H/M CPU. Thereby, the hotel service processor H/M CPU can identify the central office line call by receiving the data.
Thereafter, when the central office line responds, the extension telephone STA and the central office line enter a communication state, and this data is also transmitted from the connection control processor CPU to the hotel service processor H/M CPU. As a result, hotel service processor H/M
On the CPU side, first, the station line number received from the connection control processor CPU is analyzed, and frequency pulses are created and counted by the hotel service processor H/M CPU for each cycle that matches the area. This frequency pulse counting continues during a call between the extension telephone STA and the central office line. When the extension telephone STA or the central office line side is restored and the call is terminated, the connection control processor CPU detects this and sends this termination data to the hotel service processor H/M CPU. This hotel service processor H/M
By receiving this data, the CPU identifies that the call has ended, finishes counting the frequency pulses, and adds the frequency counted during the call to the frequency accumulation memory corresponding to the extension telephone STA. Hotel service operation console H/M When the operator of CON wants to read the call frequency information of the extension telephone STA, use the operation console H/M CON.
Operate M CON. Said operation console H/M CON
The operation of the hotel service processor H/M
When detected by the CPU, the operation is analyzed, and in response to a request from the console H/M CON, the call frequency data stored in the frequency accumulation memory for the extension telephone STA is added and sent to the console H/M CON. do. The operation console H/M CON receives call frequency data and can output the frequency data by displaying it on a display tube, printing it out on a printer, etc. according to the operator's request. In other words, conventionally, the hotel service processor H/M CPU and operation console H/M
CONs always had to be directly connected by a bus for transmitting control information.

FIG. 2 is a block diagram of a private branch exchange system showing one embodiment of the present invention. When the extension telephone STA makes a call to the central office line and the series of call and call termination operations are completed, the connection control processor CPU and the hotel service processor H/M CPU control the connection control processor H/M CPU to call the extension line. telephone
The frequency pulse of STA is counted, and the extension telephone STA in the hotel service processor H/M CPU is counted.
Stored in the corresponding frequency storage memory. When reading these call frequency data from the hotel service operation console H/M CON, first read the above H/M CON.
Dial the predetermined access code. This is exactly the same operation as the operation console H/M CON dialing a central office line dialing code to make a call. Connection control processor
The CPU analyzes the dial information from the hotel service operation console H/M CON, and uses the same control as a general office line trunk connection to connect the time division switch TDSW between the operation console H/M CON and the dedicated processor H/M CPU. Connect via From then on, readout and control of call frequency information by operating the operation console H/M CON is performed using the dedicated processor H/M.
The CPU will do this, and the connection control processor
It is completely separated from control from the CPU, reducing the load on the connection control processor CPU. In other words, hotel service operation console H/M
Operation information from CON is sent to hotel service processor H/M via time division switch TDSW.
The information is transmitted to the CPU, and the processor H/M CPU analyzes the operation information and processes the call frequency data of the extension telephone STA, which is already stored in the frequency storage memory, in response to a request from the console H/M CON. Reply to hotel service operation console H/M CON. This operation console H/M CON outputs the call frequency data by displaying it on a display tube or printing it out with a printer, etc., according to the operator's request. If you use a switch with this configuration, the operation console H/M CON
Since the connection between the processor H/M CPU and the processor H/M CPU can be performed using the same control as the exchange between general extension lines or between an extension line and a central office line, there is no need to always connect them via a bus. Also, since the operation console H/M CON is housed in the time division switch TDSW like the general extension line,
It is also easy to add a telephone call function to the operation console H/M CON.

FIG. 3 shows another embodiment of the present invention, in which there are n hotel service operation consoles (n is an integer of 2 or more). Each device is as shown in Figure 2.
The hotel service control H/M CPU has multiple connection terminals. The present invention can be applied by providing n input/output ports within the processing capacity of this processor. In such a case, the physical amount of the data transmission device H/M INT between the hotel service console and the hotel service control processor can be reduced compared to the conventional switching device.
