JPS62239752A - Automatic designated time reorigination system - Google Patents

Abstract

PURPOSE:To regenerate designated time for a re-caller by providing the 1st memory for storing information on a final caller corresponding to each extension and the 2nd memory for storing re-origination information specified by the re-caller. CONSTITUTION:The final caller information memory 50 is stored with pieces of final caller information corresponding to extensions A and B under the control of a central controller CC and the reorigination information memory 51 is stored with pieces of information on the re-caller and a called subscriber and a next table address. The CC searches a timer origination link table 52 with current time all the time and when the current time coincides with time set in the table 52, information on the extension A is read out of the memory 51 and information on the extension A in the table 52 is deleted, and a call signal is sent out to the extension A. When the extension A responds to the call, the CC reads the information on the extension B out of the memory 51 and transmits a call signal to the extension B and an audible ringing tone to the extension A respectively. Consequently, a call to the final caller is automatically made at allotted time.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to an automatic re-transmission system at a specified time.

[Conventional technology]

Conventionally, if a caller wants to talk to the other party again at a new time after completing a call, he or she dials the number of the called party again when the desired time comes and makes the call again.

[Problem that the invention seeks to solve]

In the conventional redial system described above, the caller had to redial the last caller's number when the desired time arrived, which could result in missed calls, late calls, misremembering of the called party's number, or dialing. The drawback is that mistakes can occur due to mistakes.

[Means for solving problems]

The specified time automatic re-call system of the present invention comprises a first memory that stores information on the last caller corresponding to each extension, a second memory that stores re-call information specified by the re-caller, and a timer call link. and a re-transmission table, so that when the re-transmission designated time comes, the re-transmitting party automatically re-transmits the call to the end caller.

〔Example〕

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

FIGS. 1(a), (b), and (c) are configuration diagrams of a final caller information memory, a re-calling information memory, and a timer transmission link table, respectively, in an embodiment of the present invention, and FIG. FIG. 2 is a block diagram of an automatic exchange illustrating an application example.

In Figure 2, the automatic switchboard is a general type, with extension A
, B, etc. (hereinafter referred to as 5W) 1, and an outgoing register trunk (hereinafter referred to as ORT>2.
The MM5 is equipped with a tone trunk (hereinafter referred to as TNT) 3, a central control unit (hereinafter referred to as CC) 4 that controls the entire exchange, and a main memory device (hereinafter referred to as MM) 5, and the MM5 has the functions shown in FIGS.
, the last caller information memory 50 shown in (c). Retransmission information memory 51. A timer transmission link table 52 is included.

The last caller information memory 50 stores the last caller information (for example, accommodation position information on the SWI of the extension, extension subscriber number, etc.) corresponding to extensions A, B, . . . under the control of the CC 4. Further, the retransmission information memory 51 stores information on the retransmission party and the called party and the next table address under the control of the CC 4. Further, in the timer transmission link table 52, retransmission time information (numeral information for the hour 1) based on the dial of the retransmitting party is set under the control of the CC4.

Next, the operation of this embodiment will be explained.

Here, if it is assumed that the call between extension A and extension B has ended, the last caller information memory 5
The address of extension A of 0 contains the information of extension B, and the address of extension B
The information of extension A is stored in the address, and the information of extension A and B is stored in the address.
goes on-hook9 In this state, for example, when extension A goes off-hook as a repeat caller and after hearing the dial tone from 0RT2 dials the access number for setting re-call time information, as is generally known, extension A goes off-hook. A special dial tone is sent from TNT3. Extension A who heard this special dial tone
When the caller dials the number of the re-call time information, the CC 4 stores in the re-call information memory 51 the information of the re-caller (extension A) read from the last caller information memory 50 and the called party (extension B).
information is stored and incorporated into the timer transmission link table using the retransmission time information. When this setting is completed, as is generally known, a pre-service setting message is sent from TNT3, and the repeater (extension A) listens to this pre-service setting message and goes on-hook.

The CC4 always searches the timer transmission link table 52 using the current time, and when the current time matches the time set in the timer transmission link table 52, it reads the information of extension A from the retransmission information memory 51 and searches the timer transmission link table 52. 52, the information on extension A is deleted, and a calling signal is sent to extension A using a generally known method. When extension A answers this call, the CC 4 reads the information of extension B from the re-call information memory 51 and sends a ring signal to extension B and a ring tone to extension A in a generally known manner. .

〔Effect of the invention〕

As explained above, the present invention provides information on the last caller by providing a first memory for storing the last caller information for each extension in an automatic exchange and means for specifying and storing re-call time information. This has the effect of automatically re-transmitting at a specified time.
