The present invention relates to a method for translating a called party number of a private exchange to translate a called party number in a private exchange to determine a called line. By determining the called line corresponding to the called number, the translation of the called number can be performed quickly and accurately.

Description

How to translate the call forward number in a private exchange

The present invention relates to a method of translating a called number of a private exchange, and more particularly, to a method of translating a called number of a private exchange to translate a called number in a private exchange to determine a called line.

An object of the present invention is to provide a method for translating a called party number of a private exchange to search a called party table for called party data according to the called party in a private exchange to determine a called line corresponding to the called party.

10,12,14: first, second, third access switching subsystem

16: I / O subsystem 20: Subprocessor

22: private subscriber line subsystem 24: trunk line subsystem

26: signal control subsystem 28: switching and number translation subsystem

The above and other objects and various advantages of the present invention will become more apparent from the preferred embodiments of the invention described below with reference to the accompanying drawings by those skilled in the art.

Hereinafter, an embodiment of the present invention for achieving the above object in detail.

1 is a block diagram showing an embodiment of a private exchange for applying a called number translation method of a private exchange according to the present invention, wherein each of the first, second, and third access switching subsystems of each basic unit system of the private exchange; (Access Switching Subsystem (ASS) 10, 12, 14) and an input / output subsystem (IOS) 16 for matching with a system operator.

An embodiment of a private exchange for applying the present invention thus made will be described in detail with reference to FIGS. 2 and 3 as follows.

First, each of the first, second, and third access switching subsystems 10, 12, and 14, which are the basic unit systems of the private exchange, has a matching function for accommodating the subscriber and the relay line, the signal from the subscriber, and the switching period signal processing. It provides subscriber circuit and line test function as well as function for switching function for communication and communication line.

Next, the input / output subsystem 16 for matching with the system operator is connected to each of the first, second, and third access switching subsystems 10, 12, and 14 by a redundant T-bus. Performs program loading, data back-up, storage and analysis functions of the second and third access switching subsystems 10, 12, and 14, and a man machine communication function with a system operator. To provide.

FIG. 2 is a detailed block diagram illustrating each of the first, second and third access switching subsystems 10, 12 and 14 according to FIG.

First, the line processor (LP) 20 monitors the state of each private subscriber line and reports the status to the higher processor, receives a control command of the upper processor, and controls each private subscriber line, and the private subscriber line subsystem (Private) The subscriber line subsystem (PLS) 22 registers with the private subscriber through the sub-processor 20 to process subscriber service, control system state, manage and process call information, and process relay line service.

Next, a trunk line subsystem (TLS) 24 processes a relay line service with another station and processes data by the relay line in order to match private subscribers through the lower processor 20 with another station. And route control matching to process route data accordingly.

A Signaling Control Subsystem (SCS) 26 sends and receives frequencies to and from the private subscriber line subsystem 22 to allow signal matching for each operation of the private subscriber line subsystem 22.

In addition, the Switching & Number Translation Subsystem (SNS) 28 communicates with the private subscriber line subsystem 22 and the trunk line subsystem 24 to translate the number from its private subscriber or other station. Switch subscribers in a time-division manner.

At this time, in the above-mentioned number translation, when looking at the called party number translation, as shown in FIG. From the information, the incoming line corresponding to the called number is determined (30, 32, 34, 36).

3 is a flowchart illustrating a step-by-step embodiment of a method for translating a called party number of a private exchange according to FIG. 1. 16) can be entered.

As described above, the present invention enables the private exchange to quickly and accurately translate the called party by searching the called party table for the called party data according to the called party to determine the called line corresponding to the called party. There is.
