JPS6380659A - Re-dialing system for assigned time - Google Patents

Abstract

PURPOSE:To avoid to forget making a call by setting re-dialing assigned time and informing an operator that time has come for making a call from an exchange in assigned time. CONSTITUTION:With executing hooking, a special number for re-calling assigned time is dialed, and time for re-calling is continuously dialed if a caller is absent, a central control unit 6 accummulates the telephone number of the caller which is previously and temporarily stored and information on assigned time for re- calling the dialed number in a storage device 7. The central control unit 6 periodically reads the contents of the storage device 7, compares information on re-calling time and present time information from a system clock 8 and if they coincide, calls a telephone set 1 and transmits that a voice synthesizer 9 re-calls and the telephone number to be re-called to the telephone set 1 by voice. If it is not on-hooked, the central control unit 6 uses a sender 4, transmits the telephone number for re-calling to a trunk 3 and connects the telephone set 1 and the trunk 3.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a designated time redial system in a telephone exchange.

[Conventional technology]

Traditionally, when the person you want to talk to (called the called party) is not home, the operator (caller) waits a certain amount of time or asks when the person you want to talk to will be home before calling. It's being fixed.

[Problem that the invention seeks to solve]

However, in these cases, the operator must check the time and then make a call again, so the operator must always be aware of the time. Also, the operator may forget to call back.

[Means for solving problems]

The specified time redial system of the present invention includes a storage means for storing time information and a called party's telephone number specified by a caller who encounters an absence of a called party, a clock means for transmitting current time information, and a clock means for transmitting current time information. and means for audibly notifying the caller that it is the designated time together with the called party's telephone number read from the storage means when the current time information and the designated time information from the storage means match.

〔Example〕

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

Referring to a diagram showing an embodiment of the present invention, 1 is a calling party's extension telephone, 2 is a subscriber circuit, 3 is a trunk, 4 is a sender, 5 is a call path switch, 6 is a central control unit, and 7 is a subscriber circuit. 8 is a storage device, 8 is a system clock, and 9 is a speech synthesizer. An operator (caller) uses telephone l to call the recipient of an outside line. At this time, the central control device 6 temporarily stores the telephone number in the storage device 7. If the called party is absent, the system asks when the called party will be back, hooks them up, and then dials a special number to call back at the specified time. Subsequently, by dialing the time to retry the call, the central control device 6 stores in the storage device 7 the called party's telephone number temporarily stored in advance and the specified time information for retrying the dialed call. The central control device 6 periodically reads the contents of the storage device 7 and compares the time information for re-calling with the current time information from the system clock 8. As a result, when the time information for re-calling and the current time information match, the central control unit 6 calls the telephone 1, and when the telephone 1 answers, it reads out the telephone number information to be re-dialed from the storage device 7 and synthesizes the voice. The device 9 converts the telephone number information into voice and sends to the telephone 1 the message that a call is to be made again and the telephone number to be called back in voice. At this time,
When the telephone 1 goes on-hook, the central control unit 6 determines that there is no need to make a call again and interrupts this connection service. If telephone 1 does not go on-hook, central controller 6
uses sender 4 to send a telephone number to call back to trunk 3, connects telephone 1 and trunk 3, and terminates this service. The call begins when the called party answers.

〔Effect of the invention〕

As explained above, according to the present invention, the operator makes a redial call by setting a designated redial time and notifying the operator that it is time to redial the call from the exchange at the designated time. You don't have to worry about the time. Also,
It is possible to prevent forgetting to make a call.

Claims (1)

[Claims] A storage means for storing time information and a telephone number of the called party designated by a caller who encounters an absence of the called party, a clock means for transmitting the current time information, and a current time information from the clock means and a specification from the storage means. and means for notifying the caller by voice that it is the designated time together with the called party's telephone number read from the storage means when the time information matches.
