Description

Description: TECHNICAL FIELD The present invention relates to a private branch exchange (key telephone, private branch exchange, etc.) capable of accommodating a plurality of types of external lines.

2. Description of the Related Art Taking a key telephone as an example, conventionally, an outside line button provided on an extension telephone is depressed, or a special number such as 0 is depressed from an extension transmission state to catch an outside line.

Also, recently, a vacant outside line is captured by simply lifting a receiver or pressing a special button (for example, a speaker button or the like) provided on an extension telephone without raising the receiver, and a transition is made to an outside line transmission state.

[Problems to be Solved by the Invention] However, in the above-described conventional example, another external line accommodated by a plurality of accommodated external lines is, for example, an analog PBX extension line.

It is a digital public network (such as INS nets in Japan).

It is an international telephone line (Route KDD in Japan
etc).

In the case where they are mixed, there are the following disadvantages.

(1) When an external line button provided on an extension telephone is depressed and captured, it is necessary to remember which button the desired line is assigned to, which is troublesome.

(2) In the case of catching a vacant outside line just by transmitting a special number 0 or picking up the receiver, it is difficult to determine which type of outside line has been caught.

(3) In the case of the above (2), when a dial for talking with the other party is input without being discriminated, there is a very high possibility that an erroneous dial will occur.

(4) Even if the outside line is of a type that the user does not want to select, it will be captured if it is free.

(5) Since a vacant outside line of the type desired to be selected can be captured from another inside line, the user may encounter a busy state and cannot use the outside line.

[Means for Solving the Problems] In view of the above points, the present invention provides means for accommodating a plurality of outside lines and a plurality of outside lines buttons each provided with a plurality of outside line buttons corresponding to each of the plurality of outside lines. Means for accommodating an extension, means for pre-registering a trunk type for each accommodated external line, means for pre-registering a preferentially-captured trunk type which the extension preferentially acquires for each accommodated extension, Means for determining whether or not a setting for capturing an outside line by off-hook of the receiver when the off-hook of the receiver or operation of the speaker key is performed, and a setting for capturing an outside line by off-hook of the receiver by the determination means are set. If it is determined that there is no outside line, it waits for the input of a predetermined number for outside line transmission, and on the other hand, it is judged that the setting to catch the outside line by off-hook of the handset is made. Means for capturing a vacant outside line from the outside lines of the trunk type that matches the priority acquisition trunk type registered corresponding to the extension without waiting for the input of the predetermined number. It is provided.

M601 corresponds to a PBX extension line, M602 corresponds to a digital public network line, and M603 corresponds to an international transit network line. The data shown in FIGS. 5 and 6 is registered from the ten keys 203 after the setting key 205 is pressed to enter the setting mode.

FIG. 7 shows a display example of the display unit 201, in which 700 is a dial monitor unit, 701 is an LCD dot unit, and indicates that the extension is currently capturing an analog public line.

 This will be described with reference to the flowchart of FIG.

When the CPU 122 detects that the 200 handsets are off-hook in step S300, the process proceeds to step S301.
Also, when it is detected in step S400 that the speaker key 207 has been pressed, the process proceeds to step S301. Step S301
If the setting is such that the outside line is immediately captured when the receiver is picked up (hereinafter, outside line default), step S3
Go to 05. If it is not the outside line default, the CPU 122 waits for the pressing of the outside line key 202 (step S302) or the input from the ten keys 203 (step S303) in step S303. Here, when the dial "0" is input, it is treated as a number for making an outside call, and the process proceeds to step S305. If a dial other than "0" is entered, the process waits for the input of the second and subsequent dials in step S312, and transmits an extension.

Now, assuming that the calling extension is the extension telephone 101, for example, the CPU 122 extracts the extension-based priority-capturing trunk type corresponding to the extension telephone 101 in step S305. In this case, the first “1” is extracted with reference to the memory M401. CPU122
In step S306, the outside line of trunk type '1' is
Search the trunk type setting data for each outside line shown in the figure. In this case, it matches the memory M500, M501,
In step S307, it is determined whether either of them is free, that is, whether there is a free space in the analog public network lines 110 and 111. If not, the memory M401 is referred to again in step S308, and the trunk type '3' registered next is extracted, and step S3
Return to 06.

If there is no next registration in step S308, the outside line capturing process is stopped, and in step S309 a busy tone (busy tone or the like) is transmitted to the calling extension.

If there is a vacant outside line in step S307, the CPU 122 selects character data corresponding to the trunk type extracted in step S310. For example, when the trunk type is “1”, the character data “ANN” in the memory M600 is selected.
This data is transferred to the extension and displayed. This display example is shown in FIG.

The outside line selected in step S311 and thereafter is captured, and the processing shifts to outside line transmission processing.

If any one of the eight external line buttons 202 whose external line lamp 202L is not lit is pressed in step S302, the CPU 122 proceeds to step S310.

Also, if it is detected in step S302 that the outside line button has been pressed while the busy tone is being transmitted in step S309, the process proceeds to step S310.

As described above, in this embodiment, a plurality of types of lines are accommodated, and the type of line to be preferentially acquired is registered in the memory 123. At the time of calling an outside line, the CPU 122 selects a line based on the registration in the memory 123, captures the selected line, and makes a call according to a key input from the extension telephone.

If the line registered in the memory 123 is not free, the operator can select another type of line by using the outside line key 202. In this case, CPU 122 captures the line corresponding to the depressed outside line key and makes a call according to the key input from the extension telephone.

Therefore, operability can be improved by registering in advance the types of lines frequently used by the operator. Further, even when a pre-registered type of line is not available, it is possible to manually make a call using another type of line. That is, it is possible to use another type of line when an emergency is required.

[Effect of the Invention] As described above, according to the present invention, for an extension set to catch an outside line by off-hook of the receiver, the extension user operates the speaker key by off-hook of the receiver. This makes it possible to catch a trunk type outside line that is frequently used with a simple operation.In particular, it is possible to improve the usability of the speaker key, and further, it is set that the outside line is captured by off-hook of the handset. If the extension uses an external line even if the extension uses more external calls than the private line exchange, the trunk type external line that is frequently used when the extension uses an external line is used. Can be captured.

(1) Even if the user does not remember which trunk type outside line is assigned to which outside line button, by registering in advance, a desired trunk type outside line can be captured.

(2) By displaying the trunk type of the captured outside line, erroneous dialing can be prevented. In other words, if you want to access the analog public network, if you directly capture the analog public network line or if you capture the PBX extension line, the latter is '0' etc. when you capture the analog public network line accommodated by the PBX. This is because it is necessary to enter a special number.

(3) If a trunk type that the user does not want to capture is not registered, the trunk type is not captured even if the outside line of the trunk type is free.

(4) If the desired trunk type is registered and the trunk type is not registered in all other extension setting data, only the extension in which the desired trunk type has been registered can capture the outside line of the trunk type, thereby making a simple call. Regulations can be realized.

And so on.
