In accordance with another aspect of the present invention, there is provided a method for verifying a normal installation of a line and a port of a switch, including: performing initialization at system on after system installation; Detecting the incoming of the dial tone through the occupied track by occupying each track of the system; When the incoming of the dial tone is detected within a predetermined time, recording the detection result in a memory and confirming the presence or absence of polarity inversion with respect to the corresponding line; And if the polarity inversion does not occur within a predetermined time, recording the detection result in a memory and notifying a steady state. Here, the polarity reversal checking process is characterized in that it is confirmed whether the polarity inversion signal bit is switched on in case of a trunk line, and whether the off-hook signal bit is in a switched state in case of a dedicated line.

Alternatively, the line and port normal installation checking method of the exchange according to the embodiment of the present invention notifies the error state when the incoming of the dial tone is not detected within a predetermined time or when the polarity reversal occurs within a predetermined time. Characterized in that the process further comprises a.

The present invention facilitates installation by monitoring whether the installation is normal by a program at the time of installation of the exchanger and displaying the result. Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

Looking at the installation structure of the exchange according to an embodiment of the present invention, as shown in Figure 1, the MST block 20 for collecting the PSTN (10), the line applied through the PSTN (10), and the corresponding MDF It consists of a switch 20 and a terminal 40 connected to the block 20 and the line, in the switch 30 to control all the configuration blocks for checking the normal installation of the line and port of the system And a main control board 31, a local channel board 32 for connecting to the MDF block 20, and an extension subscriber board 33 for connecting to the terminal 40. Here, the entire system is composed of the respective building blocks in the corresponding exchange 30 through a system bus. Then, as shown in Fig. 2, the local channel board 32 includes an audio hybrid circuit and signaling circuit 32-1 for monitoring dial tone and the like, and off-hook monitoring for monitoring whether polarity of a dedicated line is correctly installed. And a polarity inversion monitoring circuit 32-3 for monitoring whether the polarity of the trunk line is correctly installed.

In addition, as shown in FIG. 3, the line and port normal installation confirmation system of the switch according to the embodiment of the present invention includes an initialization block 11 for initializing the system when the system is powered on, and a hardware line. Line monitoring block 12 for monitoring whether or not it is normally installed, an error transmission block 13 for notifying the main control board 31 when a system installation error occurs, and an LED (Light for showing the installation status of the system) And a display block 14 such as an Emitting Diode.

Referring to the operation of the line and the port normal installation confirmation system of the exchange according to an embodiment of the present invention.

As shown in FIG. 1, the track from the local exchange to the MDF block 20 through the PSTN 10 is a section managed by an institution, and the installation section of the installers is the terminal 40 in the corresponding MDF block 20. Installers take a considerable amount of time to install from their MDF block 20 to the exchanger 30, and they should normally install more than 2,000 strands of wire only in the installation work for their subscribers. It can be said that there is always a lot of time and error.

Therefore, the line and port normal installation confirmation system of the exchanger according to the embodiment of the present invention is a large portion of the manual installation at the installation company at the time of system power-on (Power-on of System) automatically in the exchanger 30 itself And the result of the execution can be checked directly with the eyes of the installer through a display device such as an LED, and a message is applied to the main board 31 in the exchanger 30 through the system bus. By transmitting the result to the system operation management program or the external output monitor in (31), from the installer's point of view, it is possible to determine whether there is an abnormality in the line construction at the same time as the installer, and also find and correct the abnormal port. .

In addition, the switch 30 may be divided into several types. The terminal 30 is connected to the switch 30, and the subscriber is connected to the terminal 40 so that the user can use the switch 30. ) And subscribers to trunk lines and trunk lines. Here, the invention that can be applied to trunk lines and leased lines is described as follows, but the description also applies to lines connected to other switching systems of networks such as Integrated Services Digital Network (ISDN), Internet, etc. You can understand that it is possible.

First, when the installer installs the system and powers on the system, the system is set up, and the main board 31 and the local channel board 32 perform the initialization program by the board's own program and initialize the corresponding program. After the program is executed, an initialization program is performed between the main board 31 and the local channel board 32.

At this time, the program module according to the present invention is performed while the board self initialization program and the initialization program performed between the main board 31 and the local channel board 32 are performed.

That is, the local channel board 32, which is a trunk line and a leased line board, occupies the trunk line and the leased line after executing an initialization program, and a dial tone is introduced through the trunk line and the leased line according to the occupation of the trunk line and the leased line. Lose.

Accordingly, the local channel board 32 detects a dial tone coming through the trunk line and the dedicated line as shown in FIG. 2 and stores the detected result in an internal random access memory (RAM), thereby communicating. It can be determined that the necessary hardware line is installed normally.

Then, a program is performed to check whether the polarity inversion signal bit is in an active on state from the polarity inversion detecting circuit 32-3 to determine whether the polarity is correctly installed from the trunk line. Let it be. In other words, if it is switched on, it means that its polarity has changed.

Accordingly, by combining the results of the dial tone detection and the results of the polarity test, which were tested as described above, the port status and the installation construction status can be confirmed, and the installation contractor can immediately confirm the result regarding the presence or absence of an error at this time. The input / output port is always connected to the main board 31 by sending the result to the main board 31 through the system bus and providing the corresponding data to be processed by the operation and diagnostic program. You can check it simply.

Alternatively, in case of a leased line, the same as in the case of the trunk line described above, but if there is a difference, in the case of a trunk line, a polarity reversal signal bit is detected to check whether the polarity of the installation is twisted, and in the case of a leased line, it is off-hook. The monitoring circuit 32-2 detects the off-hook signal bit to check whether the installation polarity is twisted and installed, i.e., if the off-hook signal bit is switched to the act-on state, the polarity is changed.

In order to install the system as shown in FIG. 1 again, the installation of the section from the corresponding MTF block 20 to the user's terminal 40 except for the MTF block 20 managed by the institution operator is provided. Should be in charge of installation.

At this time, to install complex lines at once, it is necessary to perform the actual test for all ports because installation of reverse polarity or poor contact and tip ring of ports may be mixed with adjacent ports. This is cumbersome. By adding a program module to perform the above-described operation on a program in a pyrom mounted on the board at the same time as the installation, the installer can easily identify and correct an installation error.

Then, referring to the block diagram of FIG. 3 and the flowchart of FIG. 4, a method of confirming a normal installation of a line and a port of an exchange according to an embodiment of the present invention is as follows.

First, at the moment when the installer installs the system as shown in FIG. 1 and the system is turned on, the exchanger 30 performs setup, and the initialization block 51 performs initialization for each component block (step S1). .

The line monitoring block 52 occupies each line installed in the first step S2 (step S2) and detects the incoming of the dial tone through the occupied line (step S3). In the case where S3) detects the incoming of the dial tone within a predetermined time, it is determined that the line of hardware necessary for communication is normally installed and the detection result is recorded in the internal RAM (step S4).

Then, in order to determine whether the polarity is correctly installed on the checked line, as described above, in the case of the trunk line, the presence of the polarity inversion signal bit is checked by the polarity inversion detection circuit 32-3. In the case of a dedicated line, the off-hook monitoring circuit 32-2 checks whether the off-hook signal bit is switched on or not, that is, whether the corresponding polarity inversion signal bit or off-hook signal bit is switched to the act-on state. Check whether the polarity is inverted with respect to the identified line (step S5).

Accordingly, if the polarity inversion is not detected within a predetermined time in the fifth step S5, it is determined that a port for a line of hardware required for communication is normally installed and the corresponding detection result is recorded in the internal RAM (step S6).

That is, by combining the dial tone detection result of the third step (S3) and the polarity reversal detection result of the fifth step (S5), it is possible to check the installation construction state such as the line, port state, etc. By displaying the normal status report to indicate the normal state on the display block 54, such as an LED, so that the installation contractor can immediately check (step S7), and also the corresponding normal status report through the system bus the main board 31 In step S8, normal operation (Operation) of the local channel board 32 is performed.

On the other hand, if the incoming of the dial tone is not detected within the predetermined time in the third step S3 or if the polarity reversal is detected within the predetermined time in the fifth step S5, an error occurs in the corresponding line. An error status report is determined in the error transmission block 53 to determine the case and informs the error of the corresponding line, and is sent to the main board 31 to control the normal operation of the corresponding line not to be performed (step S9). In addition, the corresponding error status report is displayed on the display block 54 so that the installation contractor can immediately check (step S10).

Accordingly, the installer can determine the installation state of the system by checking only the display block 54 such as the LED, and in the case of an error, it is possible to fix and install it immediately, and the installation cost is low, so that the reliability of the product can be improved. do.

As described above, according to the present invention, installation, maintenance, and the like at various distribution structure stages such as the design, manufacture, sale, distribution, installation, and maintenance of the exchanger are closely related to customers, and the installation is also influential with the sales network. Increasing the intimacy of the product by reducing labor costs or installation costs and convenience of installation by the maintenance and maintenance companies, and increasing the frequency of introduction compared to other products with their convenient installation and maintenance when the customer introduces the product.
