JPS60130251A - Absence transfer telephone connecting system - Google Patents

Abstract

PURPOSE:To allow a caller to know in advance a call to be subjected to absence transfer by transmitting a message that the connected call is subjected to absence transfer to the caller. CONSTITUTION:When a subscriber A hooks off and dials the number of a subscriber B, an outgoing register 8 receives and counts it and transfer the information to a central controller 2. The controller 2 collates this information with the storage content of a data memory device 3 and when it is detected that the number is registered for absence transfer, a talkie trunk 4 is acquired to connect the subscriber A and the trunk 4 and a message of absence transfer is transmitted to the subscriber A. Then the controller 2 reads information of subscriber C being destination of absence transfer from the memory device 3 and connects the subscribers A and C. Thus, the subscriber A makes a call after the connection destination is the subscriber C.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a call forwarding telephone connection system for an automatic exchange that connects a calling subscriber to a subscriber to whom a call is forwarded in accordance with the registration when a subscriber having a call forwarding function registers a call forwarding function. .

In the conventional call forwarding telephone connection system, when the integrated number is dialed for a subscriber who is registered for call forwarding, the call is immediately connected to the call forwarding destination subscriber. Therefore, on the calling side, is the call received to the subscriber of the dialed number or to the subscriber to whom the call was forwarded? Since the call cannot be identified, when the call is connected to the subscriber to whom the call is forwarded, the call after reading the call often causes confusion and misunderstandings.

SUMMARY OF THE INVENTION An object of the present invention is to provide a call forwarding telephone connection system that allows a calling subscriber to know in advance when there is a call forwarding function, thereby preventing unnecessary confusion during calls. It is in.

In order to achieve the above object, the call forwarding telephone connection system according to the present invention connects a call to an absent subscriber registered in a data memory device to a designated call forwarding destination subscriber. In the call forwarding connection method, when a call is detected for a subscriber who is registered for call forwarding, the calling subscriber's talky trunk is connected via the main switch, and the announcement device connected to this talky trunk is connected. When the time control device is activated and causes a predetermined voice message to be sent to the calling subscriber and starts counting the time according to the activation of the announcement device, when the time control device has counted the predetermined time, the time control device transmits a predetermined voice message to the calling subscriber. It is configured to connect to the specified forwarding subscriber.

According to the above configuration, the calling subscriber can know in advance that the call is a call forwarding call through the voice announcement, so confusion at the time of connection can be prevented, and the object of the present invention is completely achieved.

Hereinafter, the present invention will be explained in more detail with reference to the drawings.

FIG. 1 is a diagram showing an embodiment of a call forwarding telephone connection system according to the present invention. In the figure, 1 is the main switch (MS
W), 2 is a central control unit (OPU), 3 is a data memory unit (DMU), 4 is a talkie trunk (TKT),
5 is an announcement device (AM), 6 is a time control unit (TCU), 7 is an intra-office trunk (IOT), and 8 is an outgoing register (OR).

The announcement device 5 displays the necessary information to notify the transfer, such as "The subscriber is currently registering for call forwarding. Please wait for a while as we will connect you to the call forwarding destination from here." Pre-recorded.

Since subscriber B is an i-telephone with a call forwarding function,
When subscriber C is registered as the call forwarding destination and subscriber C is specified as the call forwarding destination, subscriber B is registered for call forwarding in the memory area of the data memory device ff3 containing call forwarding data. It is stored that the transfer destination is subscriber C. When subscriber A makes a call, central control unit 2 captures call register 8 and connects subscriber A and call register 8 through main switch 1. When the calling subscriber A dials the number of subscriber B, the calling register 8 receives and counts it and forwards the information to the central controller σ2. The central controller 2 compares the received dial number with the contents stored in the data memory device 3, and when it detects that the subscriber B is registered for call forwarding, it seizes the talkie trunk 4 and switches the main switch. 1 connects subscriber A and talkie trunk 4.

When the talkie trunk 4 is connected to a subscriber, it activates the announcement device 5, so that the announcement device 5 sends a message to the subscriber to forward the message.

On the one hand, the talkie trunk 4 and the announcement device 5
The time control device 6 starts counting time. The time control device 6 is provided to allow time for the tape of the announcement device to make one revolution and for sending out necessary information.

Therefore, when the time for -rotation is counted or the time for one rotation of the tape is counted by a sensor or the like, a signal indicating this is outputted to the central control unit #2. Central control device 2
When it receives this signal, it reads out the information of the subscriber C who is the destination of call transfer from the data memory device 3, and calls subscriber 0.

The elderly subscriber recognizes from the above message that the calling subscriber is not subscriber B, but subscriber C, who is subscriber B's call forwarding destination. Therefore, as a result of subscriber C's response, the central controller 2 captures the trunk 7 within its own station, and connects the calling subscriber A and subscriber C via the main switch 1.
Even if subscriber A is connected, subscriber A can talk to subscriber C knowing that the other party is subscriber C.

Although one embodiment has been described above, the present invention can be similarly applied to various types of connections such as an input connection from a trunk line input connection board and an office line input connection.

As described in detail above, according to the present invention, when an automatic exchange has a telephone with a call forwarding function, both parties can notify the calling party whether or not the call connected within the automatic exchange will be forwarded. can be identified before making a call.
