Abstract

PURPOSE:To obtain information concerning a calling subscriber in addition to main wire incoming before reply at the time of main wire incoming by providing a device that detects additional dial and storing information such as caller identification number, lamp number etc. in a memory. CONSTITUTION:When a main wire subscriber makes additional dialing of number related to the caller himself according to predetermined form, the additional dial information is sent to a central controlling unit 5 through an incoming register trunk 7. In the central controlling unit 5, this additional dial information is compared with caller identification number registered beforehand in a memory 6. If it is incoming from a registered caller, lamp number corresponding to the caller is determined. Basing on this, the central controlling unit 5 sends out lamp number information to a switch box 8 together with main wire incoming information. When the switch box 8 receives main wire incoming information and specified lamp number information, a lamp 10 for indicating main wire incoming is lit up, and at the same time, corresponding specified individual display lamps L1-L15 are lit up, and an operator of the switch box 8 is informed of main wire incoming and information related to the caller.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an incoming call display method for a central office line in an automatic private branch exchange.

Conventionally, when an automatic private branch exchange detects an incoming call from the central office line, the relay stand or central line display panel simply displays that there is an incoming call from the central office line, and no unique information about the caller is displayed. was not displayed, and therefore no information about the caller could be obtained before answering.

An object of the present invention is to configure an automatic private branch exchange to accommodate a central office line that allows for additional dialing, in view of the central office line receiving system of conventional automatic private branch exchanges, and to receive additional dialing information from central office line subscribers. The object of the present invention is to provide an incoming call display method that can display information regarding the caller in addition to displaying incoming calls on a central office line, using information preset in a storage device.

In order to achieve the object of the present invention, the configuration of the present invention is as follows:
In an automatic private branch exchange that accommodates a central office line capable of additional dialing, when an incoming central office line call is detected by a terminating central office line trunk, an additional dialing detection means is connected to the terminating central office line trunk to collect additional dialing information from the central office line subscriber. Based on the information set in advance in the storage device, the caller receives an incoming call on the relay stand or on the central line display panel, and sends β:j to the caller.
)\IN is displayed.

Next, one embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a relay system diagram showing an embodiment of the incoming call display method according to the present invention, and FIG. 2 is a diagram showing the board of a relay stand in accordance with the same embodiment.

In the 11th part, l is the central office subscriber, 2 is the central office exchange, and 3
is an incoming trunk of the automatic private branch exchange, 4 is an exchange switch of the automatic private branch exchange, 5 is a central control unit, 6 is a storage device, 7 is an input register trunk, and 8 is an intermediary (stand).

As will be described later, the storage device 6 controlled by the central control device 5 stores data that associates additional dial information from the central office line subscriber 1 with the number of the caller's lamp displayed on the relay console 8. Registered in advance.

First, when the central office line subscriber 1 dials the subscription@month of this automatic private branch exchange, the terminating central office line trunk 3 detects an incoming call. At this time, the terminating office line trunk 3 sends a detection signal to the central control unit R5, and upon receiving this, the central controller 5 connects the terminating office line trunk 3 and the input register trunk 7 via the path 9 of the exchange switch 4. Connect. As a result, the automatic private branch exchange becomes capable of detecting additional dials from the central office line subscriber 1.

Next, in such a situation, the central office line subscriber (caller) receives a number related to himself (caller) according to a predetermined format.
For example, if you make an additional dial (related to affiliation, position, etc.), this additional dial information will be sent to the entry register trunk 7.
It is sent to the central control device 5 via. Central control device 5
In the caller, this additional dialing information is compared with the caller identification number pre-registered in the storage device 6, and if the call is from a registered caller, the caller is contacted. A lamp number is determined. Thereby, the central control unit e5 sends the above-mentioned lamp number information to the relay stand 8 together with the station line incoming information.

On the other hand, on the panel of the relay stand 8, there are arranged a lamp 10 for indicating incoming calls on the central office line as shown in FIG. 2, and individual display lamps L1 to L15 corresponding to each local line subscriber. therefore,
When the relay stand 8 receives the central line incoming call information and the specific lamp number information, the central line incoming call display lamp 10 lights up, and the corresponding specific individual display lamps L1 to L15 light up, and the relay stand 8's lamp 10 lights up. Inform the operator of the incoming call and information about the caller.

In this way, the operator of the relay console 8 can reliably know unique information (information on affiliation, status, etc.) regarding the caller before answering the incoming call.

Incidentally, if the individual display lamps L1 to Lts of the relay stand 80 in the above embodiment are configured to double as push button switches, and a plurality of individual display lamps L1 to L+s are lit at the same time, An incoming call with a high tentative priority may be selected and answered by pressing one of the buttons at the discretion of the operator of the relay console 8.

In addition, in the case of a distributed relay stand system, by providing individual display lamps on the station line display panel, etc., the caller's information can be displayed before answering an incoming call, as in the above embodiment. There is no point in saying anything that can be constructed so that it can be known.

As explained above, according to the incoming call display method according to the present invention, a means for detecting additional dialing is provided, and information such as a caller identification number and a lamp number is stored in a storage device. When receiving a line call, the system has the advantage that it is possible to obtain not only the fact that the call is received by the central office line but also the information regarding the calling name before responding to the call.
