The present invention relates to the formation of a call path according to a subscriber connection between an extension and an extension in a private automatic branch exchange, and in particular, a method of making a call with a specific button to a subscriber having a special relationship of an executive and a secretary. It is about.

The general private automatic branch exchange has various additional functions such as subscriber and extension subscriber, subscriber and domestic subscriber, private exchange and leased line service during private exchange.

In addition, the general telephone call between the extension and the extension was able to talk to the other party by dialing several digits, such as 3 or 4 digits of the extension number. However, despite the need for frequent phone calls between two subscribers, for example, two subscribers, such as executives and secretaries, they use separate interphones or dial the whole digits. Not only is it inconvenient to call, but it is also a problem that it is difficult to promptly handle all incoming calls during busy work because it is not possible to selectively receive calls from executives from outside (national lines, leased lines, extensions). It has emerged.

It is therefore an object of the present invention to provide a service method that allows two subscribers in close relationship to be easily called and a person in a special position can selectively answer the call.

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

1 is a block diagram of a private branch exchange (PABX), a microprocessor (MPU) (I) that collectively controls the overall operation of the private branch exchange (PABX), the operation control program and operation data of the system A memory unit (J) for accessing and writing the data under the control of the microprocessor (I), an interface (G) for buffering and interfacing the input / output data of the microprocessor (I), and the subscriber station. A subscriber line circuit (SLC) for supplying a voice current of a voice band to the telephone of the telephone and interfacing between the subscriber telephone and the switching system, and the digital tone and speech data under the control of the microprocessor (I). Multiplexing (Speech Data) to send the data corresponding to the voice band to the corresponding timeslot (Time Switch) (T) and the micro A multi-frequency signal generated from a digital tone supply circuit (B) for generating various tone signals under the control of a parser and outputting them to the time switch (4) and subscribers of the subscriber circuit (A). CodeMF (DTMF Receiver) E for analyzing the code and inputting corresponding digit data to the microprocessor 10, and a tone sender DTMF for converting a dial pulse into a complex frequency signal under the control of the microprocessor. Under the control of the sender (F) and the microprocessor 10, the empty trunk line is seized to form a trunk line loop, an incoming signal coming from the trunk line, and an outgoing from the exchange to the trunk line. Outgoing trunk line trunk (C) for interfacing the signal, and by the control of the microprocessor (I) occupies a dedicated line (TIE Line) outgoing the input signal (Outgoing) and other A dedicated line circuit (D) that transmits a Seizure Acknowledge signal to a signal coming from a private exchange and interfaces a dedicated line between each private exchange (station and station), and an external music device unit for using an external music source function ( K).

2 is a memory table for recording the port numbers of the executive and the secretary according to the present invention. For example, the upper two bytes record the port number of the executive and the lower two bytes correspond to the executive. Record the port number of the secretary to be used as a pair of upper and lower 4 bytes, and a total of serviceable executive-secretary pairs can be made up to 40 pairs in consideration of memory capacity and the entire system line. The executive-secretary must be recorded as "1 to 1".

3 is a flowchart according to the present invention, a first process of determining whether there is an external call, a second process of determining an extension hookoff when there is no external call, connecting an extension ring tone at a hookoff, and inputting a talker button; A third step of determining whether the caller button is a senior secretary function button when detecting a talker button input; and if the caller is a senior secretary button in the third step, the caller judges whether the caller is a senior or secretary. The fourth process of finding the corresponding port number, and if the executive / secretary number is found in the fourth process, connects a call to the talker if the station is busy, and if the station is not in use, the channel of the executive and the secretary The fifth process of connecting the, and when there is an external call in the first process and the non-executive secretary button input in the third process to analyze and receive the dial If he is not an executive, perform general processing, and if the receiver decides to make sure that the call to the executive is always connected to the secretary, and is directed to the executive, if the executive is not busy and the call is not rejected, If you are connected to the executive's line, and the executive is busy or not on the call, and the call to the executive is always connected to the secretary, the secretary may be found in the memory to determine whether the secretary is busy and could not find the secretary. In the sixth process to connect an external telephone and an executive, and in the sixth process, when the assistant is not busy, the assistant connects to an external telephone. Or check the hook on / off status of the external telephone, and if the hook on is detected, cut off the call and terminate the call. If it is not in the hook-on state, it continuously checks whether the executive secretary function button is input, and when the executive secretary function button is input, connects music to an external telephone and finds the executive corresponding to the secretary from the memory. If the executive is found in step 7, the executive judges whether the executive is busy or not. If the executive is not found in the seventh step, or the executive picks up the external phone and the secretary during the call, the eighth process is to connect the call to the secretary's phone and connect the telephone line between the executive and the external phone. It consists of.

The present invention will be described in detail based on the above configuration. In step (1), the microprocessor (I) checks the trunk line trunk (C) to determine the presence of an external call. At this time, when there is no external call, in step (2), the state of the extension subscriber circuit A is scanned to determine whether the extension is hooked off. When the hook-off state is detected as a result of the scan, the process proceeds to step (3). The microprocessor (I) stores the state and number of the hooked-out call subscriber in the memory (J) and simultaneously controls the time switch (T). By assigning a reception time slot to the subscriber circuit (A) and connecting a tone sender (F) to hear a dial tone (DT: Dial Tone) and waits for the subscriber to dial.

After performing step (3), the microprocessor (I) checks whether a call extension is in use by checking whether there is a caller button input in step (4). If the call extension is in use, proceed to step (15) to connect the busy tone to the caller and loop to step (1).

If the call extension is not in use in step (9), the process proceeds to step (10). The call signal generated from the ringer (H) to notify the called party through the corresponding receiver port of the subscriber circuit (A). (Ring Signal) and send the tone sender (F) to the corresponding sender port of the subscriber circuit (A) to inform the caller that the call path is configured and the called subscriber is not busy, the tone sender (F) Connect ring back tone generated from).

After performing step (10), in step (11), the subscriber circuit (A) is scanned to detect the hook on or off state of the called party. In step (12), the ring signal supplied to the receiver and the ring back tone supplied to the receiver are cut off, and the time switch T is controlled to connect the executive and secretary's communication paths. At this time, the display window displays the secretary to the executive, the secretary to the executive so that you know who the other party. If there is no button input, go back to step (3) and continue dialing the caller until a predetermined time has elapsed or the handset is turned off.If there is a button input, proceed to step (5) and dial. Transmits and applies the button input to the tone receiver (E), and the tone receiver (E) converts this signal into a digital digit and inputs the signal to the microprocessor (I) to check whether the button input is a executive secretary function button. . If it is determined that the executive assistant function button, the process proceeds to step (6) to read the data recorded in the memory (J) to check whether the talker is the executive or secretary.

In this case, if it is determined that the data is found to be an executive or secretary, the process proceeds to step (7) to find a port number identical to its own port number in the memory table as shown in FIG. In step 8), it is determined whether the magnetic port and the relative port number exist.

If the port number is not found in step (8) or if the caller is not an executive or secretary in step (6), proceed to step (16) to give the talker a tone through the tone sender (F). : Send Not use tone and display error message on display window.

If both the executive and secretary ports exist in step (8), the microprocessor (I) is in the subscriber circuit (A) state of the talker and the receiver in step (13) after step (12) is performed in step (9). If the hook-on of either side is checked while the watch is checked, the call is ended and terminated in step (14).

When it is determined in step (5) that the executive secretary function button is not input and when it is determined that the call is an external call in step (1), the call is made from a trunk line, a leased line, or an extension. Perform dial analysis through dial counting operation and proceed to step (18) to determine if the dial analysis result is a caller. If not, regard the call as a general telephone and give a ring to the caller in step (41). If it detects that it has been hooked off, it will perform the normal processing of connecting the channel.

In step (18), the receiver proceeds to step (19) to check the memory to check whether the call to the executive is set to always be connected to the secretary. In step 42, the subscriber circuit A is checked to determine whether the executive is in a call when the test result is directly connected to the executive. Determine if the call is rejected. If it is found that the memory area is not set to the incoming call rejection state, the process proceeds to step 44 to control the time switch to connect the external telephone line and the executive line in the same manner as described above.

In step (42), if the executive is in a call or in step (43), the executive reception rejection status is temporarily connected to the secretary in step (19). Find paired secretaries. After performing step (20), if the port number of the secretary is found in step (21), and if it is not found, the process proceeds to step (44) and connects the call line of the executive and the external telephone as described above. When the corresponding secretary is found, the subscriber circuit A is checked in step 22 to check whether the secretary is busy. At this time, during the call, proceed to step (46) to control the time switch (T) to supply a ring tone to the caller through the tone center (F), and when not in a call as described in step (23). It supplies ringback tone to the talker (external telephone) until it is detected that the self hooks off and the ring is supplied to the talker (secretary). When the talker hooks off, the subscriber circuit (A) detects the microprocessor (I). In addition, the microprocessor (I) establishes a call with an external telephone by controlling the time switch (T) to designate a call route to the calling subscriber (secretary). After performing step (23), in step (24), the microprocessor (I) checks whether there is an executive assistant function button input, and if no, proceeds to step (39). If the hook-on state is detected by monitoring the disconnection of the call in step (40) and terminates, and if the hook-on state is not returned to step (24) to repeat the above process.

If the executive assistant function button is input in step (24), proceed to step (25) to connect the held music to an external telephone through the external music device unit (K), and read the memory table in step (26). Find the corresponding executive port number. In step (27), if the executive port number is found, and if the executive port number is not found, proceed to step (45) to reconstruct the call path of the external telephone and the secretary. On the other hand, when the corresponding executive port number is found in step (27), the subscriber circuit (A) is checked in step (28) to check whether the executive is busy. When not in a call, in step 29, the executive port connects the ring through the ringer (H) and the non-support connects the ring tone through the tone sender (F) to announce the establishment of the call. In step 30, the subscriber circuit A checks whether the executive has hooked off. If the test result is not in the hook-off state, continue to perform step (29). If it is recognized that the hook-off state is detected, the ring and ringback tone are cut in step (31), and the call of the executive and secretary in step (32). Connect it.

In establishing this channel, the executive may receive the contents of the call from the secretary and, if necessary, receive the secretary's information on the work with the talker (external phone) without picking up the external telephone, and the secretary may re-call with the external telephone. It can also happen. Therefore, in step (33), it is determined whether the pick-up button is input through the subscriber circuit (A). If there is no button input, the process proceeds to step (45) to reconfigure the communication path between the secretary and the external telephone. In this case, the tone receiver E converts this signal into a digital digit and inputs it to the microprocessor I. If it is detected that the executive has picked up the external telephone is suspended, the microprocessor (I) controls the external music device (K) in step (34) to cut off the music on hold of the external telephone, step (35) Releases the opening of the call between the executive and the secretary at the same time, and controls the digital tone supply circuit (B) to transmit a ring tone to the secretary's telephone, and in step (36), controls the time switch (T). Connect the telephone line.

After performing step (36), the process proceeds to step (37) to monitor the state of the executive and external telephone subscriber circuits (A) and if the hook-on is recognized, the call path is cut and terminated in step (38). At this time, while the executive and the external telephone call, the executive may press the executive secretary function button to make the secretary and the external telephone call again, but the process is the same as the above process.

As described above, the extension and extension calls between specific subscribers can be made by pressing a single button to provide prompt and convenient use to the subscribers, as well as by selectively connecting calls to specific subscribers through other subscribers. There is an advantage to work efficiency.
