Abstract

PURPOSE:To eliminate the need for redialing by a subscriber for the purpose of inquiry of charge by providing a talking charge managing equipment managing and displaying a talking charge in trunk line outgoing call and a voice synthesizer informing the displayed charge to an extension subscriber. CONSTITUTION:The private branch of automatic exchange is provided with a central controller (CC) 1, an extension subscriber circuit (LC) 3 connected to an extension telephone set 2, a trunk line trunk circuit (T) 5 connected to a trunk line 6, a channel switch 4 containing the LC 3 and the T 5, a charging equipment (CH) 9 connected to the CC 1 via an interface circuit (IF) 8, a voice synthesizer (SS) 7 accommodated in an SW 4 and a central storage unit (MM) writing/reading thec charging information by the CC 1. Thus, the CH 9 calculates and displays the number information and the charging information and the SS 7 informs them to the telephone set 2 via the SW 4 and the LC 3 immediately after the end of trunk line talking.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to an audible system for calling charges, and in particular, in an automatic private branch exchange, the call charges for making a call to one line are automatically announced audibly to the calling extension after the call ends. Relating to an audible method of notification of call charges.

[Conventional technology]

Conventionally, when a caller who made a call to a local line wanted to know the call charge, the caller who made a call to the central office had to call the telephone again after the call was over. The method used was to inquire about the price displayed on the machine.・ [Problems to be solved by the invention] In the conventional call charge audible system described above, when an extension subscriber who has made a call to a central office line wants to know the call charge, the subscriber who has made a call to the central office line has to call the extension number again after the call ends. Since it is necessary to inquire from the telephone set about the call charge displayed on the billing device, there is a drawback that the call charge cannot be automatically audible after the end of the call with the single station line.

[Means for solving problems]

The call charge audible method of the present invention includes a charging device that manages and displays the call charge when an extension subscriber makes a call to a central office line in an automatic private branch exchange, and a voice synthesizer that notifies the extension subscriber of the displayed charge. Equipped with equipment.

〔Example〕

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

FIG. 1 is a block diagram of an automatic private branch exchange showing an embodiment of the call charge audible system of the present invention, and FIG. 2 is a diagram schematically showing an example of billing information stored in the central storage device in FIG. be.

In FIG. 1, the automatic private branch exchange has a central control unit (hereinafter referred to as CC) 1, an extension subscriber circuit (hereinafter referred to as I, C) 3 connected to an extension telephone 2, and a central office line trunk circuit connected to station 1@6. (hereinafter referred to as T) 5, a communication path switch (hereinafter referred to as 5W) 4 that accommodates LC3 and T5, and an interface circuit (hereinafter referred to as 5W) 4.
A charging device (hereinafter referred to as ct-i) g connected to CC1 via IP) 8, and a voice synthesis device (hereinafter referred to as ct-i) housed in 8W4.
58) 7, and a central storage device (hereinafter referred to as MM) 10 in which charging information is written and read by CC1.

All operations of the automatic private branch exchange are controlled by CC1, so that the calling subscriber can call LC3°8W4 . T5
When a call is made to the station fs6 via the MMIO, the number information and billing information of the subscriber's extension number 9, central office line originating dial number 1, and call time shown in FIG. 2 are all stored in the MMIO. CH9
is these number information that eel read from MMIO, R
It receives all information via IP9, calculates and displays call charges based on the information, and stores this call charge information in the MMIO via IP8, eel. In addition, the call charge information received from the 887-ke CC1 is used to synthesize the call charge, and immediately after the end of the central line call, the 8W4
, and sends a notification to the extension telephone 2 via the LC3.

Next, the operation of this embodiment will be explained.

When extension telephone 2 (subscriber's extension number is 1300") and office line 6 enter a call state via the queen's route, cc1
1'i As is well known, the central office line dialing number (04xx-xx-xxxx) from the calling subscriber has already been recognized and stored in the MMIO. CC1 also monitors the call status of T5 and adds the call time. When this call ends, CC1 monitors the recovery state of T5, calculates the call charge (750 yen) from the call time (3.15 minutes) based on the recovery information, and stores it in MMIO.

At the same time, the CCI sends this call charge information to 887 and controls 8W4 to connect the link between S87 and LC3. on the other hand.

887 converts the call charge information 11 into an audio signal 12, edits the message "Current call charge is 750 yen", and sends it to the °CP 3-line telephone 2 via the LC3.

〔Effect of the invention〕

As explained above, the present invention makes a call to the central office line and informs the subscriber who has terminated the call by driving the voice synthesizer for transmitting the call charge message after the end of the call on one central office line in the automatic private branch exchange. We will notify you of the charges automatically, so
This has the effect of eliminating the need for subscribers to dial again to inquire about charges.
