The present invention relates to a method for calling an operator in a key phone system, and more particularly, to a method for calling an operator corresponding to a previously registered extension number according to day or night.

In general, a private exchange such as a key phone system sets a specific extension as an operator to perform an operator service for guiding in response to a call by the extension. The operator function is a function mainly used in offices, hospitals, hotels, etc., so that extension stations of information desks, nurse waiting rooms, and counters are designated as operators to enable calling of other stations.

In the conventional key phone system, a separate service was provided for a designated call extension when receiving a trunk line according to day / night mode. As described above, the conventional key phone system has a function for distinguishing between day / night mode, but the extension subscriber inputs a key to call the operator and calls the subscriber or extension group corresponding to the operator regardless of day or night. Only one operator is called.

As described above, the key phone system has a function of distinguishing between day / night, but there is a problem in that the service is not provided when the extension subscriber calls the operator.

Therefore, an object of the present invention is to provide a method for registering the extension number of the operator provided according to the day and night.

Another object of the present invention is to provide a method of calling an operator of the corresponding extension number according to day and night when an operator call request is made.

Still another object of the present invention is to provide a method of calling an operator of the corresponding extension number according to the day and night by calling the operator using the same number regardless of the day / night mode.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram of a key phone system according to the present invention, wherein the CPU 110 performs an overall control process of the key phone system according to a set program. In addition, when the CPU 110 detects a signal for calling an operator, the CPU 110 reads the corresponding extension number according to day / night and calls the operator corresponding to the read extension number. The interface unit 112 provides various control signals applied from the CPU 110 to each component including the switching circuit 114, and provides data provided from each component including the switching circuit 114 to the CPU. Interface to (110). The memory unit 120 stores an operation program of the CPU 110. In addition, the extension stores the subscriber's extension number according to the execution of the program for performing the exchange function in the key phone system and the operator's extension number according to the day / night. The switching circuit 114, under the control of the CPU 110 when the call request is made, connects the trunk line subscriber circuit 116 or the internal subscriber circuit 118 to which the call request is input and the corresponding part requested for the call. The trunk line subscriber circuit 116 connects a plurality of general trunk lines and leased lines drawn from a local exchange under the control of the CPU 110 to the switching circuit 114. The extension subscriber circuit 118 connects a plurality of extension subscriber lines to the switching circuit 114 under the control of the CPU 110. The tone generating unit 122 is controlled by the control of the CPU 110. A tone signal is generated and output to the switching circuit 114. The key phone subscriber circuit 124 connects the key phone terminal corresponding to the operator and the switching circuit 114 under the control of the CPU 110. In addition, interfacing the transmission and reception data and signals between the key-phone terminal and the switching circuit 112, and supplies the talk current of the key-phone terminal. The key subscriber subscriber circuit 124 has a corresponding key / night key terminal to be scissored by a call request from an operator of an extension subscriber. The DTMF receiver 126 receives the DTMF signal received from the switching circuit 114, converts the DTMF signal into digital data, and provides the same to the CPU 110. The DTMF transmitter 128 transmits a DTMF signal to the switching circuit 114 under the control of the CPU 110.

FIG. 2 is a diagram illustrating a control flow for registering an extension number of an operator to be called according to day / night in a key phone system according to the present invention. FIG. 2 illustrates an operator setting mode when a program operation key and a key for operator setting are input. The process of performing the operation, when the key input for setting the weekly operator is detected in the operator setting mode, and receiving and registering the weekly extension number, and when the key input for setting the night operator in the operator setting mode is detected. Registering by receiving the night extension number, and if the program operation end key is input after the registration is completed, the process of ending the setting program.

FIG. 3 is a diagram illustrating a control flow for calling an operator according to day / night in a key phone system according to the present invention. When a signal for calling an operator is detected, FIG. Calling the extension number is a process of forming a call.

Therefore, an embodiment of the present invention will be described in detail with reference to FIGS. 1, 2, and 3.

First, the extension number registration process will be described with reference to FIGS. 1 and 2. In operation 210 of FIG. 2, the CPU 110 detects whether an operation key for operating a program is input from a key phone terminal, that is, an operator. At this time, it will be apparent that the input of the operation key is applicable to all the key phone terminals as well as the key phone terminal corresponding to the operator.

After the operation key is input in step 210, when a setting code for implementing a key phone terminal setting mode corresponding to the operator is input in step 212, the operation proceeds to step 214 to operate in the operator setting mode. The setting code is a code for selecting an operator function among various functions provided by the key phone system. In addition, the CPU 110 detects whether the '' 1 '' key corresponding to the key for setting the extension number of the key-phone terminal to be connected when the extension subscriber calls the operator during the day in step 216. When the '' 1 '' key is detected, the CPU 110 determines that it is a registration request of the weekly extension number and proceeds to step 218. In step 218, if it detects whether the extension number of the key-phone terminal (operator) to be connected during the day is detected and proceeds to step 220. In step 220, the CPU 110 registers a weekly extension number registration table (hereinafter, referred to as a `` weekly table '') provided in the memory unit 120.

However, if the '' 0 '' key is detected in step 222 instead of the '' 1 '' key, the CPU 110 determines that the night extension number is registered and proceeds to step 224. In step 224, if it detects whether the extension number of the key-phone terminal (operator) to be connected at night is detected and proceeds to step 226. When the CPU 110 proceeds to step 226, the CPU 110 registers a night extension number registration table (hereinafter, referred to as a `` night table '') provided in the memory unit 120.

When the registration of the extension number is terminated in steps 220 and 226, the CPU 110 detects whether a program operation end key is input from the key-phone terminal requested for registration in step 228, and if the end key is detected, step 230 Proceed to end the program.

Next, referring to FIG. 1 and FIG. 3, the calling process will be described. In operation 310 of FIG. 3, the CPU 110 detects whether there is a key input for calling a key phone terminal corresponding to an operator from an extension subscriber or an extension group. The key typically uses '' 0 '', which is used the same regardless of day / night mode.

If the call key is detected, the CPU 110 determines whether the CPU 110 is set to the day mode. In step 312, the CPU 110 proceeds to step 314. The day / night mode may be set by an operator who operates an operator, or may be set by another extension subscriber's request.

When the CPU 110 determines in the daytime mode in step 312, the CPU 110 proceeds to step 314. Read out. On the contrary, when it is determined that the night mode is not the day mode, the CPU 110 proceeds to step 316 and the operator extension number, that is, the night extension number of the keypad terminal set to be called at night, is provided in the memory unit 120. Read from the table.

When reading the daytime or nighttime extension number in steps 314 and 316, the CPU 110 proceeds to step 318 and calls the operator key phone terminal corresponding to the read daytime or nighttime extension number. On the other hand, if the call is connected by the call operation in the call mode in step 320, while performing a call in the call mode periodically performs step 322 to detect the end of the call. If the end of the call is detected, the process proceeds to step 324 to switch to the standby mode.

As described above, according to the present invention, operators of day and night can be designated separately so that different services can be received when the operator changes according to day or night. Therefore, operator calls such as hospitals, hotels, and offices are frequent, and at night, the operator can be more usefully provided with normal operator service at the place where employees leave the office.

In addition, since the operator is called using the same key regardless of the day / night mode, the operator can be called by the same operation as in the prior art, so that the subscriber who is provided with the service can be provided with better service by the same operation.
