Description

Method for managing automatically trunk line

The present invention relates to an exchange line management method for automatically managing an exchange line, which is connection information of an exchange period, in connection with a transmission device connection information in a switching system, and a computer-readable recording medium having recorded thereon a program for realizing the method. .

The exchange line is also called the interstation line, and refers to the line of logical concept connected between trunks of two exchanges. Strictly speaking, the trunk line is at the channel level.

By the way, the conventional trunk (Trunk) is coming out to the DS1 (Didital Signal level) class, and the connection between the terminals, so the connection between the DS1 terminal can be seen as the inter-station circuit.

The management of the inter-station line was to manage only the connection information between the trunks of the exchanges, regardless of the management of the connection information that is made by communication signals coming out of the trunks of the exchanges. Therefore, in the case where the exchange line is defective, the exchange room has never known which transmission path is conventionally associated with it.

The exchange line is associated with the transmission line, and the definition of the exchange line name itself is confusing when the exchange trunk terminals on both sides differ. For example, if a line name is assigned to an exchange line configured between a T1 trunk and an E1 trunk, it cannot be logically formed. Therefore, the line names have to be in the form of a list according to the channel (Ch) level. If it is to be managed by the operator, it will take considerable time and effort.

As described above, since all exchanges are composed of T1 and E1 trunks, the asymmetric trunk connection and the asymmetric exchange circuit management allow the operator to manage the transmission path and connection information in tracking the difficulty and failure of management. Brings a break.

Therefore, by selecting the transmission device connected in the trunk of the switchboard, the inter-station line is automatically generated and the corresponding transmission line is connected. Ultimately, the operator automatically generates a list of line names for the asymmetrical switch line. There is a necessity for a scheme to free the user from the trouble of assigning switch circuit names.

SUMMARY OF THE INVENTION The present invention has been made to meet the above-mentioned demands, and realizes a switching circuit management method and the method for automatically managing the switching circuit which is the connection information of the switching period in connection with the transmission device connection information in the switching system. The object of the present invention is to provide a computer-readable recording medium having recorded thereon a program.

Also, it will be readily appreciated that the objects and advantages of the present invention may be realized by the means and combinations thereof indicated in the claims.

In order to achieve the above object, the present invention provides a method for managing an asymmetric type switch circuit (inter-station circuit) in an exchange system, wherein the switch device is identified based on a transmission path by identifying a transmission device connected between the trunks of the asymmetric switch type. (Connection information of the exchange period) is generated, but if the transmission device is a converter, the switching circuit is recorded at the terminal on the transmission path side, and the transmission path side exists even for the rim T1 trunk which is not mapped one-to-one with the E1 trunk. Providing an exchange opportunity line and distinguishing an asymmetric type exchange opportunity line for each channel; Generating a line name list for each asymmetric switch line based on the connection information between the asymmetric switch trunk and the transmitter, by mapping the asymmetric switch line to the transmitter; And managing the asymmetric switch line based on the list of line names.

On the other hand, the present invention checks the transmission device connected between the asymmetrical switch trunk in the switching system having a processor in order to automatically manage the switching line, the switching circuit based on the transmission path (connection information of the switching period) If the transmission device is a converter, record an exchange line at a terminal on the transmission path side, and if the transmission path side exists even for a T1 trunk that is not mapped one-to-one with the E1 trunk, the exchange circuit is given. Distinguishing an asymmetric type switching circuit for each channel; A function of generating a list of line names for each asymmetric switch line based on connection information between the asymmetric switch trunk and the transmitter by matching the asymmetric switch line to the transmitter; And a computer readable recording medium having recorded thereon a program for realizing the function of managing the asymmetric switching opportunity line based on the line name list.

The present invention provides a method for automatically generating an interstation line by selecting a transmission device to be connected in a trunk of an exchange and connecting a corresponding transmission path. Ultimately, it automatically generates a list of line names for asymmetrical switch lines, allowing operators to escape the trouble of assigning switch line names.

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

1 is an exemplary configuration diagram of a hardware system to which the present invention is applied.

As shown in FIG. 1, the hardware system to which the present invention is applied includes a central processing unit 11, a main memory device 12 connected to the central processing device 11, and an auxiliary memory device connected to the main memory device 12. 13, the input / output devices 14 and 15 connected to the central processing unit 11 and the peripheral device 16 connected to the main memory device 12 are provided.

The main memory device 12 and the auxiliary memory device 13 serve to store a large amount of data, and the input / output devices 14 and 15 include a general keyboard, a display device, and a printer.

However, since the computer hardware environment having the configuration as described above is only a technique well known in the art, detailed description thereof will be omitted herein. However, a method of automatically managing the switch circuit installed in the main memory device 12 or the auxiliary memory device 13 will be described in more detail with reference to FIG. 2.

2 is a flowchart illustrating an example of a switch trunk input procedure according to an embodiment of a method for automatically managing a switch line according to the present invention.

As shown in Fig. 2, the switch circuit automatic management method shows that everything starts with work on the switch trunk.

For trunk manipulation, the process of input 202, modifications 206 to 209, and deletions 204 and 205 is performed. That is, when the trunk is input 201, the transmitter input process 202 is performed, when the trunk is deleted 203, the trunk is deleted through the line input / delete process 204 (205), and when the trunk is modified ( 203) If you want to null the transmitter through normal update processing (206) (207), after nulling the transmitter entry in the trunk (208), enter the line entry / deletion process (209). To perform.

Here, if the trunk itself is assumed to be a table object, the transmission device item can be regarded as an attribute. It is assumed that exchange lines are configured on the basis of input of values to this item. For example, a situation in which a transmission device is not connected is assumed to be idle for a trunk.

In conclusion, FIG. 2 illustrates a process of inputting / modifying / deleting a value for the trunk of the exchange itself.

Now, each process will be described in more detail.

FIG. 3 is a detailed flowchart illustrating a transmitter data input process in an automatic switch circuit management method according to the present invention, and illustrates a transmitter input bitten in a trunk with respect to the trunk of the switch input shown in FIG.

The transmitter input indicates that the exchange line is configured.

As shown in FIG. 3, the transmitter data input process 202 of the automatic switch line management method is performed after inputting a transmitter item held in a trunk with respect to a trunk (302) when the transmitter is input (301). At line assignment (303), the switch line is entered / deleted (304).

In conclusion, when a command for registering a transmission device and assigning a line to the trunk inputted in FIG. 2 is inputted, a switch line input / deletion process (202, 209, 304) is called to automatically switch by the function provided by the present invention. The circuit is assigned to the trunk.

The process of inputting / deleting a switch line (202, 209, 304) is the most essential part of the present invention as shown in FIG. 4, when a trunk is input in FIG. 2 and a transmitter is registered in FIG. 3 and a line registration command is input. The routine of FIG. 4 is invoked to automatically create / maintain the exchange line.

In conclusion, in FIG. 4, the switch circuit is automatically generated to register the switch circuit in the trunk.

As shown in FIG. 4, the process of inputting / deleting switch lines 202, 209, and 304 first checks whether the trunk and the transmission device connected to the trunk are E1 / T1 converters (401).

As a result of the check, the converter is classified into a T1 trunk processing module and an E1 trunk processing module (402).

If the result is not a translator, it means that at least it is not the beginning of asymmetry in the country and you should check the information about the power. Therefore, it is determined whether the drop device of the transmission line (not the switch line) is the E1 / T1 converter in the opposite station (405).

As a result of the determination, if it is the converter, it is checked whether the exchange line is registered in the converter (409).

As a result of the check, if there is an exchange line loaded in the converter, it means that the circuit has already been created in the large station, and if not, the circuit must be created (407).

As a result of the determination, if the drop device of the opposite station is not the transducer, the large station must check the line loaded in the trunk holding the transmission path (406).

As a result of the check, if the line already exists, the line is used. If not, the line must be created (407).

In this case, the converter checks the exchange line in the converter, and in the case of a general transmission device, the trunk checks the exchange line in the trunk. to be.

Finally, in case of symmetry, the switch circuit created or referenced in the trunk of the own station is updated (408).

It is important to note that if the other station's drop device is an E1 / T1 converter, the exchange circuit must also be registered on the converter side.

5 is a detailed flowchart illustrating a T1 trunk processing procedure in an automatic switch line management method according to the present invention.

The conversion between T1 and E1 is 5: 4.

There are 24 channels ch in one T1, and there are 30 channels ch in E1, so six channels ch remain in E1 compared to T1. If the six channels (ch) are grouped into four groups, the channels become 24 channels (ch), so that the third T1 of the converter plays its role.

If the exchange line is based on the transmission line, the target of the line depends on which side the transducer is on. For example, if the translator is bitten on the E1 trunk side when the E1 trunk and the T1 trunk are connected, five transmission paths come out of the class T1 and thus five exchange circuits.

The parameter received in FIG. 5 is the trunk of the local station and the range of channels used. For example, the channel "1 to 24" in the trunk "Yeongdeungpo-Tx01-00-00001" is the value.

As illustrated in FIG. 5, the T1 trunk processing process 404 of the automatic switch line management method according to the present invention first checks whether T1 acts as a stylus (501).

As a result of the test, if T1 does not act as a stool, it belongs to "1, 2, 4, 5", which means that it is not a stalk, otherwise it belongs to "3" and it is a T1.

Therefore, if the T1 number is "1, 2, 4, 5", the converter checks whether an exchange line is registered in the E1 terminal corresponding to the T1 terminal (502), and the line is connected to the E1 side of the converter corresponding to T1. If present, the circuit is created (503) and the circuit is updated on the E1 side of the converter (504), after which the circuit is updated on the trunk (505), otherwise the circuit is immediately updated (505) on the trunk. That is, T1 1 of the converter is mapped to E1 1, 2 for 2, 4 for 3, and 5 for 4, respectively.

As a result of the check, if the T1 number is "3", the solution process for the scab T1 is performed (506 to 511).

Looking at this in more detail, first divide the channel into N class (506). Here, N represents the number of the converter E1 terminal, N 1 represents Ch 1 to 6, 2 represents 7 to 12, 4 represents 13 to 18, and 5 represents 19 to 24. Therefore, it represents one T1. Thus, the edge T1 is mapped to four E1 terminals and corresponding channels.

Thereafter, loops are formed according to the corresponding N numbers (507 to 511). That is, it is checked whether a circuit exists on each E1 side in the loop (508), if a circuit exists, a circuit is created (509), and after the circuit is updated on the E1 side of the converter (510), the circuit is updated on the trunk ( 511).

For example, data generated for one T1 trunk may be represented as shown in Tables 1 to 3 below.

The scenarios in Tables 1 through 3 are from the "00-00-01" trunk of the TDX-10 switchboard 1 system of the Yeongdeungpo telephone station to the third T1 terminal of the E1 / T1 converter of the 01 system of the 01 system in the bay "0101". If so, the order and data generation as shown in (Table 1) to (Table 3) is made.

As described above, the channel (ch) number input in FIG. 3 is input separately by dividing into N class in FIG. 5.

The trunk channel represents a channel managed by the trunk, and the circuit channel is a channel number for one circuit that can be shared between both stations. As shown in the above (Table 3), entering the T1 terminal of the converter corresponds to all four of the E1 terminal on the opposite side, so that four types of lists appear.

6 is a detailed flowchart illustrating an E1 trunk processing procedure in an automatic switch line management method according to the present invention.

As shown in FIG. 6, the E1 trunk processing process 403 checks whether a line exists on the E1 side of the converter corresponding to T1 (601) and updates the line in the E1 trunk if it exists (602), otherwise After creating the circuit (603), the circuit is updated to the E1 side of the converter (604).

Then, it checks whether the circuit exists in the converter 3 T1 (605) and if it exists, updates the circuit in the E1 trunk (606), otherwise creates the circuit (607) and then updates the circuit in the E1 side of the converter (608). ).

Here, if the E1 trunk is bitten by the translator, a transmission path is configured on the T1 side, and the switch circuit is mapped to this transmission path. Therefore, one E1 terminal in the converter is mapped to its number and the third T1. For example, in the case of its own E1 number in the converter, 1 ~ 2 times is the same, and 3-4 times E1 number is mapped to the opposite 4 ~ 5 times T1, and the remaining slit channel is the 3rd T1. It becomes a mapping. The creation and registration of each switch circuit for this is done. For example, only two trunks are shown in Table 4 below.

The exchange line is the part provided automatically in the present invention.

Note that the drop channel number varies depending on the number of the converter's E1 terminals. The system automatically inserts this information according to the input channel, and the operator only needs to list the contents of the trunk.

In FIG. 6, the N number is not given differently because the terminal E1 necessarily has two T1 lists, and it is natural to have a series of flows.

As described above, the function (Function) for the circuit generation configured in FIG. 2 to FIG. 6 is recorded as follows. Here, an exchange line number having a uniqueness in both countries and in the exchange period is generated.
