Description

How to break-in the Centx guide in a small capacity electronic changer

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a method of breaking in a centrex guide bar, in which a guide bar can be connected to a call in particular for an extension subscriber in a call.

Typically, small-capacity electronic switchboards, such as the DTS-1100, are switches that can accommodate up to approximately 8,000 subscriber lines and slightly more than 1,000 channels of relay lines, which are controlled in two stages of the upper processor and lower processor. Implemented in a hierarchical structure.

The upper processor, called the main processor, typically performs higher function tasks such as call processing, number translation, switch control, multi-frequency signal processing, system maintenance, and operation. The lower processor, called the line processor, is called the line system. It performs tasks that require real-time processing of lower layers such as sensing, analysis, and line signal processing.

The call control processing operation using the small capacity exchanger will be described as follows.

Call processing is the interaction of hardware and software to configure the call path between subscribers connected to the switching network. The call progress is as follows. That is, after detecting the handset hookoff of the subscriber and transmitting a dial tone for the subscriber to dial, the dial digit is received and analyzed to find the called subscriber to configure the call path. Thereafter, a ring current is supplied to the called party's line to call the called party, while the calling party sends a ringing tone. When the called party hooks off the handset, the call is made, the line information is processed, and when the caller or the called party detects the handset hook-on, the call is released.

On the other hand, such a small-capacity exchanger is provided with a Centrex function that provides a large number of subscribers (centrex group) in an area with an automatic on-premises telephone exchange system. When a call request is made for an extension subscriber in a Centrex group from an outgoing subscriber outside or inside the area, the Centrexe information desk connects the desired extension subscriber in the Centrex group.

Such call control processing of the Centrex function is performed when the calling subscriber outside the designated area where the call is established and the call is requested by the extension subscriber in the Centrex group that the Centrex group accepts. After the call is established, the call is connected to the calling subscriber and the extension subscriber.

However, when performing the CENTREX function, when the extension subscriber is busy, the guide cannot establish a call with the extension subscriber and thus cannot establish a call path between the calling subscriber and the subscriber. There was.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-described problems, and the method of the Centrex guide break-in method of a small-capacity electronic switchboard which allows the Centrex guide for a station extension to communicate with other subscribers who want to receive calls quickly. The purpose is to provide.

In order to achieve the above object, the present invention provides a CENTREX guide of a small-capacity electronic switchboard having a CENTREX function that connects to a desired extension subscriber in a CENTLEX group at a CENTLEX reception desk when a call request is provided from an external subscriber to an extension subscriber in a CENTLEX group. 12. A method for break-in, comprising: searching for an extension of a member of a Centlex group in a busy state when the external subscriber requests a call from an extension of a member of a Centrex group. If the extension subscriber in the CENTREX group is busy, providing a break-in key to the small-capacity electronic switchboard at the CENTLEX guide to form a call path between the CENTLEX guide and the extension subscriber; When the extension subscriber requests a call with the external subscriber, the Centx information desk provides a release key signal to the small-capacity electronic switch to block the previous call path of the extension subscriber, and then the call between the extension subscriber and the external subscriber. And forming a new furnace.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram of a small-capacity electronic switchboard for performing the CENTREX guide break-in method of the present invention. The main processor 100, the line processor 200, and the CENTLEX guide 300, the subscriber A, It consists of subscriber B and subscriber C.

In addition, the main processor 100 may be configured to perform call control and information transmission / reception processing with the Centrex unit 110, the Centrex guide 300, and the subscriber. A dial digit is provided and includes a number translation unit 130 for performing number translation, a trunk line service subsystem 140 for trunk line service, and trunk line data processing.

FIG. 2 is a detailed flowchart illustrating a method of brake-in-centre guide in accordance with a preferred embodiment of the present invention. Referring to FIG.

In Fig. 2, when subscriber A outside the Centrex group is talking to the member B in the Centrex group while the subscriber A is calling the member A in the Centrex group (S2), while the subscriber A is outside the center of the call, While maintaining, the dial digit of the subscriber B is input to the line processor 200 (S3). The dial digit of subscriber B is provided to the main processor 100 via the line processor 200. The dial digit of the subscriber B is provided to the number translation unit 130 through the guide call control unit 120 of the main processor 100 and the number is translated (S4), and the subscriber A is provided with a pending sound (S5).

When the number translation is performed for the subscriber B by the number translation unit 130, the Centx unit 110 requests an incoming call to the subscriber B (S6). If the subscriber B is in a callable state (S7), the main processor 100 forms a communication path between the subscriber A and the subscriber B so that a call between both subscribers is made (S8).

On the other hand, when the subscriber B is in a call state with the subscriber C (S7), the guide call control unit 120 transmits the busy voice to the Centx guide 300. When the busy sound is sent to the CENTREX guide 300, the panel of the CENTLEX guide 300 shows that the call is in a busy state.

The Centx guide 300 inputs a break-in key signal to be allocated between subscriber B and subscriber C (S9), and the break-in key signal is provided to the main processor 100 via the line processor 200. When the break-in key signal is input to the main processor 100, a call path between the CENTREX guide 300 and the subscriber B and the subscriber C is formed by interworking of the guide call control unit 120 and the centrex unit 110 (S10). ).

When the call path between the CENTREX guide 300 and subscriber B and subscriber C is established, the CENTLEX guide 300 will prompt subscriber B for call with subscriber A and if subscriber B is willing to call subscriber A, , The Centx guide 300 inputs a release key signal (S11).

The release key signal is provided to the main processor 100 via the line processor 200. When the release key signal is provided to the main processor 100, the subscriber releases the signal by the guide call control unit 120 and the centrex unit 110. The call path between B and subscriber C is blocked (S12), the call path between subscriber A and subscriber B is formed (S13), and the Centx guide 300 returns to its original state (S14).

As described above, the present invention has a very convenient effect by allowing the Centrex guide for the subscriber who is in a call to freely assign and call the other subscriber who wants to receive a call.
