Abstract

PURPOSE:To execute a decentralized incoming display through a simple control by providing an incoming display board similar to a telephone set interface and a double camp-on function on a top of an extension 1 terminal at the last order of an extension key group. CONSTITUTION:In regard to an extension connection processing system, a memory circuit MM reads data for showing that an extension is idle or busy. When an extension of a key group is busy, an operation enters a connection processing of an incoming display board LBP. In this case the memory circuit MM reads data for showing the possiblity of double camp-on. When the camp-on is possible, data is read from a group memory circuit GM for storing the extension key group coping pattern data during communications, and this reading is executed as an incoming display connection preparation in a common controller CC after camp-on registration. Based on the data, the collation with a trigger circuit TRIG is made that a key group A is connectable to a key extension B group during communications. Then the incoming display board LBP of the extension key group B is connected in the common controller CC, and the visual and audible display is executed.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The system of the present invention relates to a distributed response system in which an incoming call to a central office line is connected to a central office line by a general extension m-phone without going through a relay stand.

[Background of the invention]

In the conventional distributed response system, when a call arrives on the central office line, a control signal is sent from the central office line trunk, displayed on the central office line incoming call display panel, and a specific number is dialed from the extension telephone to answer the call. In addition, even in the direct in-line system in which an internal telephone associated with a central office line number is called directly, when the internal telephone is busy, the call is displayed from the central office trunk on the central office line incoming call display panel, similar to the above-mentioned system. The central office line trunk with a distributed call display function used in this method is relatively cost-effective compared to the central office line trunk for answering incoming calls at the relay stand.Also, it has the disadvantage that the control is somewhat complicated due to the control of the incoming call display panel. Ta.

[Purpose of the invention]

An object of the present invention is to provide a means for displaying distributed incoming calls with simple control using an inexpensive office line trunk that accommodates a relay stand.Q [Summary of the Invention] This system uses a central office line trunk, provides a simple control device at the extension terminal, and in combination with a conventionally known extension representative function realizes an incoming call display on the central office line. That is, by displaying the incoming office line call visually and audibly on the incoming office line answering panel without going through the office line relay stand, or by directly ringing the internal telephone that has been associated with the office line number in advance, Distributed response type PB that answers directly from the terminal phone
In X, a representative group of extensions is arranged so that multiple terminals of individual call extension terminals that are directly called corresponding to the office line and one extension terminal that is not associated with the office line are placed in the last position. a memory circuit for storing the configuration contents, a telephone interface incoming call display panel is provided at the end of the extension 1 terminal, and the display panel is installed near another extension group. [Embodiments of the Invention] Next, embodiments of the present invention will be described with reference to FIGS. 1, 2, and 3. First, regarding the overall connection operation, see Figures 1 and 3.
◎In Figure 1, the central office line trunk CO
When there is an incoming call at T, the common control device CC reads the office line trunk incoming monitoring data from the memory circuit MM in which standard connection processing data, monitoring data, etc. are stored, and controls whether there is an incoming call. , If there is an incoming call, the common control unit CC handles the incoming call. Also, the common control device CC uses the data used for the extension representative group and its constituent extension numbers, and allows responses to other groups only when all adjacent extensions in other groups are busy. Predetermined pattern data (in this case, an example of the pattern data is that when the representative extension A group is all busy, it can be connected to the representative internal ls group B group, and when the representative internal ls B group is all busy, it can be connected to the representative extension A group. The pattern data described above is read out from the group memory circuit GM that stores the data (possible data, etc.) [Performs the 2-extension representative connection process. The configuration of the extension representative group is explained in Figure 82. ・Figure 2 shows the 1-extension representative group. An example of the correspondence with the central office line trunk COT [,
The individual calling extension terminals EXT0 to EXTn constitute a representative group, and the incoming call display panel LBP is connected to the last position of this representative group, and the connection selection order is made in the order of ■, ■, ■, ...■. 〇 Returning to Figure 1 and Figure 3 again, the extension connection processing method is to read the data on whether the extension is free or busy using the memory circuit MM, and if the extension of the representative group is busy, connect the incoming call display panel LBP. Entering processing - In this case, the memory circuit MM reads data to see if double camp-on is possible, and if camp-on is possible, common 111! after registering camp-on! #Device C
At step C, in preparation for incoming call display connection, data is read from the group memory circuit GM which stores pattern data for when the extension representative group is busy. A Based on this data, when the representative group A is in the middle of a conversation, the common control bag 91cc checks whether the representative group A can be connected to the representative extension B group by comparing it with the trigger circuit TRIG that generates a trigger, as shown in the pattern data example above. The incoming call display LBP of the representative group B is connected to provide a visible and audible display. When the extension ff-B group displayed on the incoming call display board picks up the call, an incoming call is answered as is well known. At this time, the incoming call display board has the double camp-on function as mentioned above. As long as there is an incoming call, the incoming call display is performed.

〔Effect of the invention〕

As mentioned above, by providing an incoming call display similar to a telephone interface and a double camp-on function at the end of the @i terminal at the end of the extension representative group, the simple additional control shown in Figure 3 can be achieved. By being able to use both trunks installed at relay stations and trunks using a distributed system, costs are reduced and better service is achieved.
