Abstract

PURPOSE:To realize a private exchange having a low-cost charging function by adding an MODEM device to each of the private exchange and an office-side device and correcting simply software of the office-side device. CONSTITUTION:When a telephone set TEL in a hotel is hooked off and dialing to get an outside line is terminated, an MODEM Modem in a private exchange PBX is connected to this outside line, and a signal consisting of several bits indicating the room number of the hotel is transmitted in, for example, the FSK form. The office side receives the call from the hotel and connects an office-side MODEM Modem to this outside line and performs a prescribed switching operation on a basis of the dial signal. In this case, the signal in the FSK form which is transmitted following the dial signal is received through the MODEM Modem and is stored in a main controller CC. When an office-side charging device transmits charging information for the call to the hotel side simultaneously with the end of the call, contents of the beforehand stored signal in the PSK form are added to this information and are transmitted. The private exchange in the hotel side receives this charging information and inputs it to an office computer OC.

Description

[Detailed Description of the Invention] (a) 0 Technical Field of the Invention The present invention relates to a method of notifying billing information, and particularly to a method of notifying billing information when making a call from an extension of a private exchange in a hotel to an outside line. It is.

(b) Problems with the conventional technology According to the conventional technology, when making a call to an outside line from the extension of a private exchange 11PBX in a hotel, etc., it was necessary to make the call through a telephone exchange operator for billing purposes. . In other words, the station can bill the hotel, but cannot determine from which room the call is coming from.

Therefore, on the hotel side, it is necessary to manually monitor which rooms and where calls are made.

Since such work is very complicated, private exchanges with billing functions have recently been widely used in Japan.

However, a private exchange with a billing function has the disadvantage that it is more expensive than a private exchange without a billing function. In particular, when there is a strong demand for low prices, such as for export, and there is flexibility in specifications on the central office side, the disadvantage of using a private exchange with a billing function is that it is disadvantageous in terms of price. There is.

(C)1 Purpose of the Invention The purpose of the present invention is to eliminate the above-mentioned drawbacks of the prior art;
It is an object of the present invention to provide a cheaper billing information notification method.

(d) 1 Structure of the Invention According to the present invention, the above object is achieved by interlocking with an office computer in a private exchange equipped with a modem device,
Immediately after any subscriber in the private exchange dials an outside line, it uses the modem device to send out a signal of several bits, and the station side also has a built-in modem device and records the reception of the signal of several bits. ．． (a) Immediately after the call ends, the billing information for the call is sent to the private exchange by adding the several-bit signal on a separate line, and is input into the office computer. This is achieved by

(e) 8 Examples of the invention The figure is a block diagram showing one embodiment of the present invention.

In the figure, the dotted line indicates the equipment in the hotel, the location is the telephone in the hotel, PRX is the private exchange, Modem is the modem, OC is the office computer in the hotel, and the chain line is the equipment at the central office. A subscriber line circuit, NW is a network, CC is a main controller, and Modem is a modem.

The present invention will be described in detail below with reference to the drawings. When you take off-hook the telephone TEL in the hotel and try to call an outside line, when you finish dialing, the modem in the private exchange PBX connects to the outside line and sends out a few-bit signal in, for example, FSX format. do.

This several-bit signal is a number indicating the hotel room number.

The central office receives the call from the hotel, uses the scanning device SCH to confirm that the caller is from the hotel, which is a semi-permanent subscriber, connects the central office's modem Modem to the outside line, and dials a predetermined number based on the dial signal. performs the exchange operation.

At this time, the FSK format signal sent following the dial signal is received via the modem Modem, and the main controller C
C and stored in the main controller CC.

At the same time as the call ends, the billing device on the station side sends the billing information for the call to the hotel side, but it is not stored in this special sale.
It will be sent with the signal content in SK format.

The private exchange PBX on the hotel side receives the above billing information and inputs it into the office computer OC.

In this way, the hotel will be able to charge charges for calls made by guests staying at the hotel using the office computer OC.
It can be done using.

(f) 0 Effects of the Invention According to the present invention, as explained in detail, a modem device is added to the private exchange and the central office side equipment, and a simple modification is made to the software of the central office equipment, thereby reducing the cost. This has the great effect of making it possible to realize a private exchange with a low-cost billing function, making it very convenient for export.
