Abstract

PURPOSE:To save man-hour for collecting talking charge by providing a talking charge management memory storing advance paid monetary amount and accumulated talking charge for each extension telephone set and using a talking charge input device so as to allow the user to pay the talking charge in advance. CONSTITUTION:The user pays the talking charge in advance by a talking charge input device CIE. The device CIE identifies a depositted monetary amount and sends charge information to a controller CPU together with a dialed extension telephone number. The CPU receives the information from the CIE and stores it in an area of advance payment area of a talking charge management memory M. In the case of a call through a trunk line by an extension subscriber, the CPU checks the memory M and allows the trunk line dialing only when the advance paid monetary amount of the extension telephone set is larger than the accumulated talking charge. When the trunk line call is allowed and the called party replies, the charge at each registration is added to the accumulated talking charge in the memory M, the advance paid monetary amount and the accumulated talking charge are compared and when they are identical to each other, the office line trunk COT is interrupted forcibly.

Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to a call charge management system in a private branch exchange PBXK.

(Prior art) The call charge management function in the conventional private branch exchange PBX is as follows:
Each time an extension makes a call, a call charge is added, and when the call charge output device is operated, the call charge for each extension is output and the charge is collected.

The problem was that since fees were collected from users, the collection of fees always required a lot of manpower.

SUMMARY OF THE INVENTION An object of the present invention is to provide a call charge management system in a private branch exchange that allows call charges to be collected without any manual effort.

(Means for Solving the Problems) In order to achieve the above object, a call charge management method in a private branch exchange according to the present invention is a call charge management method in a private branch exchange in which an extension telephone number is input and a call charge is charged. a charge input device, a call charge management memory for storing the prepaid amount and cumulative call charge for each phone (extension); and a call charge management memory that receives the extension telephone number and charge information sent from the call charge input device; The prepaid amount is stored in the area corresponding to the extension telephone number, and each time the extension telephone makes a call to the central office line, the prepaid amount corresponding to the extension telephone that made the wJ line call in the memory is compared with the cumulative call charge, and the prepaid amount is larger. This configuration includes a control section that allows calling from the central office line only in certain cases.

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

FIG. 1 is a relay system diagram showing an embodiment of a prepaid call fee management system in a private branch exchange according to the present invention.

FIG. 2 is a configuration diagram of a memory for call charge management of the control unit fkOPU.

First, the user inputs the call charge in advance using the call charge input device OIE. The operating method is to dial an extension number using the numeric keys of the call charge input device C, E, and then insert banknotes or coins into the call charge input device OIE.

The call charge input device CIE inputs the input amount t” FjJ
and sends charge information together with the dialed extension number to the control unit OPU.

The control device CPU not only controls the entire father exchange, but also functions as a control section.

After receiving the information from the call charge input device OIE, the control unit gILOPIJ stores the information in the prepaid amount area of the call charge management memory M.

When an extension subscriber makes a call to the central office line, the control unit 0PU checks the call charge management memory M, and only makes a call to the central office line if the prepaid amount for the extension telephone 't1 that made the call to the central office line is greater than the cumulative call charge. and restrict outgoing calls if the amount is small or the same amount.

After a call to a central office line is permitted, the person dialing the number of the called party, and the called party answers, the cumulative call charge is recorded in the call charge management memory M each time the call charge is registered.
