Description

How to allow intercity code in private exchange

The present invention relates to a private exchange (Private eXchange), and more particularly, to a DPX-100 private exchange, a method of allowing a local exchange code of a private exchange that allows the calling party's extension subscriber to accept the long distance trunk code.

When the originating extension subscriber of the conventional private exchange uses the intercity (international intercity, domestic intercity) station code, if the user requests a call connection by dialing the receiving intercity interstate code by using his own terminal, Since the call is connected and there is no long-distance trunk line control function, there is a problem in that calls for all long-distance trunk line codes are connected and high billing is added.

The present invention has been made to solve such a problem, the purpose of which is to register after the long-distance CO line code to allow the inter-country code in the code allowance table when the originating extension subscriber of the private exchange uses the inter-country code. It is to provide a method for allowing a local area code of a private exchange that allows a calling party to transmit an announcement when the calling extension subscriber dials an existing long distance CO code.

A method of allowing a long distance code in a private exchange for achieving the above object, comprising the steps of: registering code information that can allow a long distance line using a man & machine communication connected to an input / output processor in a code allowance table in a main processor; ; After the code permission information is registered in the table, the code for using the long distance trunk line with the hook-off signal transmitted from the originating subscriber is dialed and transmitted to the main processor; The main processor, if the code for using the long distance trunk line transmitted from the calling subscriber and the long distance trunk line permission code stored in the code permission table are not the same, disconnecting the call; If the code for using the long-distance trunk line transmitted from the originating subscriber and the long-distance trunk line permission code stored in the code permission table are the same, transmitting a guide broadcast of call permission information to the calling subscriber so that the call can proceed normally.

Hereinafter, the objects and features of the present invention will be described in more detail with reference to the accompanying drawings so that the objects and features of the present invention can be more clearly understood.

1 is an overall block diagram of a method for allowing a local station code of a private exchange according to the present invention, including an originating subscriber unit 10, a line processor (hereinafter, abbreviated as LP) 20, and a line call. Line Call Simulator (hereinafter referred to as LCS) unit 22, Main Processor (hereinafter referred to as MP) 30, and Subscriber Call Control (hereinafter referred to as SCC) Unit 32, number translation (hereinafter abbreviated as NTR) unit 34, outgoing subscriber data handling (hereinafter abbreviated as SDH) unit 36, and data It is composed of a base (Data Base: abbreviated as DB) section 38, and an Input Output Processor (hereinafter referred to as IOP) section 40.

The terminal owned by the calling subscriber 10 is connected to the private exchange. In particular, the terminal is connected to the LCS unit 22 in the LP 20, which is a lower processor, dials to various called subscribers, and then a call is connected to make a call. The block owning the terminal.

The LP 20 internally includes an LCS 22, in which the LCS 22 detects a Hook Off / Hook On signal, of which the hook off signal is detected. After that, it is a sub-processor that receives a code and a digit extension number for using a long distance trunk line from the calling subscriber unit 10 and transmits the code to the SCC unit 32 in the MP 30.

The MP 30 internally includes an SCC unit 32, an NTR unit 34, an SDH unit 36, and a DB unit 38, and is connected to the LCS unit 22 in the LP 20. It is an upper processor that performs relay call processing for the subscriber unit 10 and performs a maintenance function for system state management.

The SCC unit 32 is a subscriber call control block, which is interfaced with the LCS unit 22 to perform local call, outgoing call, and incoming call processing of the originating subscriber unit 10, and generates charging information and collects statistical data. Transmitting to the NTR unit 34, and receives the inter-city trunk line allowance code number information from the NTR unit 34, and transmits the announcement broadcast according to the code allowed to the calling subscriber unit 10 through the LCS unit 20.

The NTR unit 34 is a number translation block, and if the code for using the long distance trunk line transmitted from the originating subscriber unit 10 is the same as compared with the long distance trunk line permission code stored in the code permission table in the DB unit 38, the call is normally performed. Notify the SCC unit 32 of the call permission information so that it can proceed.

Since the result of the number translation is retransmitted to the SCC unit 32 again, the SCC unit 32 transmits the announcement broadcast according to the code permission to the calling subscriber unit 10.

The SDH unit 36 is a subscriber data handling block. The SDH unit 36 processes information on a function of allowing a long-distance trunk line code transmitted from the IOP unit 40 to provide a DB unit through the SCC unit 32 and the NTR unit 34. Register in code permission table in 38).

The IOP unit 40 is an input / output processor, which is connected to the SDH unit 36 in the private exchange, and the IOP unit 40 stands for Man & Machine Communication (hereinafter, referred to as MMC). It transmits the function to allow the long-distance CO line code to the SDH unit (36).

The overall block diagram of the method for allowing the interstate code of the private exchange according to the present invention configured as described above has been described, and FIG. 2 illustrates a detailed detailed flowchart of the present invention for the method for allowing the interstate code of the private exchange.

First, by using the MMC connected to the IOP unit 40, code information for allowing inter-city local lines is registered in the code permission table in the DB unit 38 through the SDH unit 36 in the MP 30 (step 200). ).

Here, there are 64 code allowance tables in the private exchange system, each code allowance table has 20 allowance codes, and each extension originating subscriber registers in the code allowance table to receive call permission service for intercity trunks. do.

At this time, if the extension subscriber is an outgoing subscriber receiving code permission for the intercity trunk line, it is determined whether the call proceeds by translating the extension number in the code allowance table before translating the number.

After the code permission information is registered in the table, the code number for using the long-distance trunk line code with the hook-off signal transmitted from the originating subscriber unit 10 is dialed and transmitted to the SCC unit 32 through the LCS unit 20. (Step 201).

The SCC unit 32 transmits a signal for a code for using a long-distance trunk line to the NTR unit 34 (step 202).

The NTR unit 34 transmits information to the SCC unit 32 which compares the long-distance trunk line code and the long-distance trunk line permission code stored in the code permission table in the DB unit 38.

The call connection is released (step 204) if it is not the same by determining whether the long distance trunk line permit code stored in the code permission table in the DB unit 38 and the long distance trunk line code transmitted from the originating subscriber unit 10 are the same (step 203).

If the long distance trunk line permit code stored in the code permission table is the same as the long distance trunk line code transmitted from the originating subscriber unit 10 in the determination (step 203), the NTR unit 34 sets the code permission table in the procedure for translating the permission codes. The SCC unit 32 notifies the SCC unit 32 of the call permission information which can search and proceed with the call as a result (step 205).

The SCC unit 32 transmits the announcement broadcast in accordance with the inter-city trunk code allowance to the calling subscriber unit 10 (step 206).

In conclusion, after registering a long distance trunk line code number in the code permission table, if the registered long distance trunk line code is dialed from the calling party subscriber, the announcement is made so that the long distance trunk line can be allowed if compared with the registered long distance trunk line code number. The call is sent to the calling party to allow the call to the intercity.

As described above, according to the present invention described above, when a long distance trunk line code registered from a calling party subscriber is dialed after registering a long distance trunk line permission code number in a code permission table in a main processor in a private exchange, a registered long distance trunk line permit is allowed. If the code number is the same as the dialed long-distance trunk line code, the announcement is sent to the calling party subscriber to allow the long-distance trunk line, thereby making it possible to allow a call to the long-distance trunk line.
