Abstract

PURPOSE:To automatically change transferred destinations depending upon time zones, by storing plural transferred destination data and selectively reading out the transferred destination data in accordance with time information. CONSTITUTION:When a calling subscriber 11 calls up, for example, a called subscriber 12, the calling subscriber 11 is connected with the called subscriber 12 through a subscriber's circuit (LC)21, time division switch (TDSW)3, and LC22 under the control of a central controller (CC)4 and a calling signal is sent to the called subscriber 12 from a calling signal device (RG)7 through the LC22. When a fixed time has passed with no answer from the called subscriber 12, the CC4 reads out transferred destination data (telephone number of the subscriber 13 of the transferred destination) of, for example, the 1st block which is coincident with current time data from a storage device 6 and makes transferring process. In other words, the CC4 connects the calling subscriber 11 with the transferred destination 13 through the LC21, TDSW3, and LC23 and calls the transferred destination 13 by sending a calling signal from the RG7 through the LC23.

Description

DETAILED DESCRIPTION OF THE INVENTION (Technical Field) The present invention relates to a no-response transfer system, and more particularly to a no-response transfer system in an automatic exchange having a no-response transfer function.

In the conventional no-answer forwarding method, a called party (hereinafter referred to as the forwarding party) is transferred to the called party because the called party does not answer.
Since the transfer destination is fixed or only one transfer destination is set according to the station data, there is a drawback that if you want to change the transfer destination depending on the time zone, you have to reset the transfer destination each time.

(Object of the Invention) An object of the present invention is to solve the above-mentioned drawbacks by storing data on a plurality of transfer destinations and selectively reading the transfer destination data according to time information, and automatically selecting transfer destinations according to the time zone. The purpose of the present invention is to provide a non-response transfer method that makes it possible to change to

(Structure of the Invention) According to the present invention, an automatic exchange having a no-answer forwarding function includes a time identification means for identifying the time at which the call should be forwarded, and a storage means for storing data of a plurality of no-answer forwarding called parties. , a non-response transfer method is obtained, characterized in that a non-response transfer is performed to the called party based on the non-response transfer called party data in the storage device corresponding to the time information identified by the time identification means. .

(Example) Next, the present invention will be explained with reference to the drawings.　　.

FIG. 1 is a block diagram showing an embodiment of the non-response transfer method of the present invention, and FIG. 2 is a memory configuration diagram showing an example of the storage device in FIG. 1.

In FIG. 1, the automatic exchange connects calling subscribers 11, . Called subscriber 12. A time division switch (hereinafter referred to as TDSW) 3 that accommodates the transfer destination 13, a central control unit (hereinafter referred to as CC) 4, a clock device (hereinafter referred to as TM) 5 that notifies the current time data to the CC 4 from time to time, and CC4t- A storage device (hereinafter referred to as M) into which selected time data and transfer destination data are written
6, and a calling signal device (hereinafter referred to as RG) 7 that supplies a calling signal to the LCs 22 and 23. M6 is the first one as shown in FIG. Second. The memory area includes memory areas of blocks up to the nth block, and each block stores selection time data and transfer destination data. CC4 also compares the current time data from TM5 with the selected time data of each block read from M6 and determines whether they match or do not match. For example, if it matches the selected time data of the first block, CC
4 reads the transfer destination data registered in the first block and performs transfer processing to the transfer destination.

If the transfer destination data is not registered in the first block, the transfer process will not be performed. Note that the forwarding destination data of the first block that has been read out is stored until the selected time data of the next block (for example, the second block) and the current time data match and the forwarding destination data of the second block is selected. It becomes effective.

Next, the operation of this embodiment will be explained.

When the calling subscriber 11 calls the called subscriber 12t, for example, the calling subscriber 11 is connected to the called subscriber 12 via the LC21, TDSW3, and LC22 under the control of the CC4, as is generally known. and L is sent to the called subscriber 12.
A calling signal from RG7 is sent via C22t-.

Here, when a certain period of time has passed with the called subscriber 12 in an unresponsive state, the CC 4 reads forwarding party data (number of forwarding party 13) from the first plotter that matches the current time data as described above. , performs generally known transfer processing. 'That is, LC'H, "I'D8W3, L023
The i-call subscriber 11 is connected to the forwarding party 13 via the I, C23, and a calling signal is sent from the RG f to the forwarding party 13 to make a call.

According to this embodiment, by setting a different selection □ time digit for each block, the time zone (daytime) is set.

The number for non-response forwarding can be automatically changed depending on the night, holiday, etc.

In this embodiment, the case of calling an extension subscriber has been described, but the non-response transfer operation when a call is received from a central office line or a private line is also the same as described above, so a description thereof will be omitted.

(Effect of the invention) □As is clear from the above explanation, according to the non-response transfer method of the present invention, automatic non-response transfer is performed to six different transfer destinations depending on one time period, so it is convenient. This has the effect of significantly improving.
