Abstract

PURPOSE:To attain quick reply to an incoming call of other group by providing an other group representing number and using a register so as to identify the number thereby enabling a proxy reply to an incoming call other than one's own call pickup group. CONSTITUTION:Extension subscribers EXA, EXB...EXN are divided into N sets of groups of No.O-No.N in a private branch of automatic exchange having a call pickup group storage circuit 2 and a call pickup function. When an incoming call comes to an extension of a prescribed call pickup group, a proxy reply number of other group reply is dialed through an extension not belonging to the said call pickup group. Thus, proxy reply is attained.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a call pickup function of an automatic private branch exchange, and relates to an other group response call pickup method.

[Prior Art] Conventionally, this type of call pickup function has been a function in which groups of extensions have been predetermined and a proxy answer can only be made for incoming calls within the group to which the user belongs.

[Problems to be solved] The conventional call pickup function described above is inconvenient because it responds on behalf of the group to which the caller belongs, and therefore cannot respond on behalf of calls that arrive to other groups. was there.

[Means for solving problems] The present invention solves the above problems, and provides an automatic internal switching device having a call pickup function.
When an extension of a predetermined call pick-up group receives a call, a substitute answer can be made from an extension that does not belong to the call pick-up group by turning a substitute answer dial for answering another group. .

[Example] Next, an example thereof will be described with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of the other group response call pickup method according to the present invention, and FIGS. 2 and 3 are flowcharts of the group designated proxy response and unspecified group proxy response in the above method, respectively. It is a diagram.

In FIG. 1, EXA, EXE, . . . EXNt* extension subscribers are grouped into N groups from the NO, O group to the NO, N group, respectively. Also LCA, LC
B , , LCN is a line circuit, SW is a switch, CI
CT is a terminating office line trunk connected to the office line, and TOT is a tone track. Further, CC is a central control unit, l is a register, 2 is a call pickup group storage circuit, and 3 is an extension status storage circuit.

In FIG. 1, it is assumed that extension subscriber A (EXA) receives an incoming call via route A1. At this time, extension subscriber A
(EXA) and extension subscriber A (EXA)'s call-up group (No, 0 group) does not respond, so extension subscriber D (EXD) lifts the handset and dials the substitute answering dial designated for NO, O group. . Here, register 1
When it is identified that the call is a proxy response dial designated for the NO, O group, the central control unit CC reads the extension number of the NO, O call pickup group from the call pickup group storage circuit 2, and sequentially determines whether the subscriber on that extension is receiving a call. It is read out from the extension status storage circuit 3 and verified.

If no extension subscriber in the N000 call pickup group is in the incoming call state, the central controller CC closes the switch between extension subscriber D (EXD) and the re-tone section of the tone trunk TOT, so that extension subscriber D ( EXD) can hear the reorder tone from the tone trunk TOT via route A2.

Extension subscriber A in NO, O call pickup group
If (EXA) is in the incoming call state, the central controller CC identifies from where the call is being received. If the call is received from the central office trunk CICT, extension subscriber D (EXD
) and the central office trunk CICT, extension subscriber D (EXD) can answer the call to the central office line via route A3. The above flowchart is shown in FIG.

Next, in the same way, extension subscriber A (EXA) receives a central office line call, and extension subscriber A (EXA) and extension subscriber A (E
Extension subscriber L (EXL) wants to answer on behalf of extension subscriber A (EXA) because the call pickup group (No., O group) of XA) does not respond, but does not know call pickup group No. Person L (EXL) lifts the handset and turns the proxy response dial for unspecified group.

When register l identifies that it is a proxy response with no group specified, the central control unit CC reads the extension numbers of all call pickup groups from the call pickup group storage circuit 2, and sequentially checks whether the subscriber on that extension is receiving a call. It is read out from the extension status storage circuit 3 and verified.

If no extension subscriber in all call pickup groups is in the receiving state, the central controller CC sends the extension subscriber L
(EXL) and the reorder tone part of the tone trunk TOT.
(EXL) can hear the reorder tone from the tone trunk TOT via route A4.

N000 call pickup group extension subscriber A
If (EXA) is in the incoming call state, the central control unit CC identifies from where the call is being received. If the call is received from the central office trunk CICT, extension subscriber L (EX
By closing the switch between L) and the central office trunk CICT, extension subscriber L (EXL) can make a call to the central office line via route A5. The above flowchart is shown in FIG.

[Effects of the Invention] As explained above, the present invention has a proxy number for another group and identifies it in the register, making it possible to respond on behalf of incoming calls from a call pickup group other than the call pickup group to which one belongs. This has the effect of being able to respond quickly.

[Brief explanation of drawings]

FIG. 1 is a block diagram showing an embodiment of the other group response call pickup method according to the present invention. FIGS. 2 and 3 are flowcharts, respectively, at the time of group designated proxy response and group undesignated proxy response in the above method. EXA, EXB: EXN: Extension subscriber LCA, L

Claims (1)

[Claims] In automatic private branch exchange equipment that has a call pickup function, when a call is received on an extension that belongs to a predetermined call pickup group, the proxy answering dial for other groups is dialed from an extension that does not belong to the call pickup group. Other group response call pickup method characterized by the ability to respond.
