2. Description of the Related Art In order to set up a communication line between terminals via a network, a device constituting the network is instructed, and the lines set up between the devices are connected one after another to set the line. Is being carried out.

A conventional example of such communication line setting will be described with reference to FIGS. FIG. 5 is a diagram showing an example of a communication system to which the conventional example and the present invention are applied, and FIG. 6 shows a configuration example of station A in FIG. In FIG. 5, station A5A, station B
5B and station C5C are stations where lines A1 to Am, B1 to Bm and C1 to Cm connected to the terminals are collected respectively. The stations are connected by a time division multiplex transmission line 6.

Reference numeral 7 denotes a line setting system. For example, in order to set a line from the terminal A1 to B1, a vacant band of the transmission line 6C is designated and a command signal for connecting the terminals A1 and B1 to this vacant band. A command is sent out via the transfer path 8 to make a connection.

Further, the station A is composed of multiplexers (TDM) 51 to 54 as shown in FIG. The TDMs 51 and 52 send signals from subscribers to the TDM 53 or 54.
To TDM51 and 52 and TDM53 and 5
The time divisional transmission lines 61 to 64 connected between the four channels are multiplexed. The TDM 53 and 54 are connected to the transmission line 6
The subscriber signals transmitted from 1 to 64 are multiplexed on the transmission lines 6A or 6C, respectively.

Therefore, for example, when a request for line setting from the terminal A11 to the terminal B1 accommodated in the station B occurs, the line setting system 7 requests the station A to
A command is sent to the TDM 51 to connect the terminal A11 to the k-th line of the transmission line 62 and to the TDM 54 to connect the k-th line of the transmission line 62 to the g-th line of the transmission line 6C.

Upon receiving the command signal from the line setting system 7, the TDM device connects the input / output line in accordance with the instructed command. Similarly, a command is sent to the station B, an input / output line is connected, and a line is set between the terminals A11 and B1.

[0008]

As described above, in order to perform line setting between terminals in the related art, the line setting system is used to input all of the manufacturing in the network that configures the line between terminals. The command to connect the output was sent to set the line.

When it is desired to restore the line thus set to the previous line setting state for some reason, the previously set data similar to that described in the conventional example is input to the line setting system. I had to get the command sent.

Although the network configuration described in the conventional example is very simple, the actual network configuration is very complicated, and it is necessary to input a large amount of setting data in order to restore the previously set state. And it took a long time. SUMMARY OF THE INVENTION It is an object of the present invention to provide a set line restoring device of a line setting system that can easily restore a currently set line state to a previously set line state.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to FIGS. 2 is a configuration diagram of the embodiment, FIG. 3 is an operation flowchart of the embodiment, and FIG. 4 is a specific example of the line setting status recording unit of the embodiment.

In FIG. 2, the line setting status recording unit 12,
The reverse command creating unit 15 and the reverse command recording unit 16
It corresponds to the line setting status recording means 1, the reverse command creating means 2 and the reverse command recording means 3 described in FIG. An input unit 11 inputs data necessary for line setting. A command creating unit 13 creates a command required for line setting based on the data input from the input unit 11. The command recording unit 14 is the command creating unit 13.
Record the command created in. Reference numeral 17 denotes an interface (I / O), which is connected to the command signal transfer path,
Transfers command signals to the devices that make up the network. A processor (CPU) 18 performs all processing.

The operation of the embodiment will be described below with reference to FIG. In order to facilitate the operation of the embodiment, assume that the network configuration is as shown in FIG. 5 and the station A is as shown in FIG. 6, and the previous line setting was the terminal A11 of the station A and the terminal C of the station C.
There are 2 lines in 11, that is, 64 kbit x 2, but this time it is station A.
A case where one line is set from the terminal A11 to the B11 terminal of the station B will be described as an example.

Processes S1 and S2 In process S1, the input unit 11 inputs the terminal to be set this time and the set number of lines. For example, if one line is set between the terminals A11 and B11, LINE (A11, B11, 1) is input.

The input data is recorded in the line setting status recording unit 12 in step S2. That is, the terminal number and the number are recorded, as shown in FIG. LIN like this
When the data indicated by E () is input, the subsequent steps S3 to S6 are skipped and the process returns to S1 and waits.

Next, which transmission path is to be used as the transmission path between the stations is determined by referring to a line usage status memory (not shown). In the embodiment, the 100th line of the transmission line 6C (LAB) that directly connects the stations A and B is used. In order to transmit the signal of the terminal A11 on the 100th line of LAB, it is necessary to use the transmission line 62 (J2) in the station connecting the TDM 54 to the TDM 51, and which line of J2 is used. This is determined by selecting an empty line from a recording memory (not shown). In the embodiment, the fifth line of J2 is used.

When the line to be used is determined as described above, data for connecting the terminal A11 and the fifth line of the transmission line J2 from the input unit 11, for example, LINK (A11,
Enter J2 (5)). Once this data is entered,
In process S2, A11 = J2 (5) is recorded in the line setting status recording unit 12 as shown in FIG.

Steps S3 and S4 In step S3, the command creating unit 13 sends the TDM 51 of the station A to the A based on the data recorded in the step S2.
A command for connecting 11 to the fifth line of J2 is created and recorded in the command recording unit 14 in step S4.

Steps S5 and S6 In step S5, the reverse command creating section 15 creates a command to restore the previously set line from the data recorded in the line setting status recording section 12. The data shown in old in Fig. 4 is the line setting status that was set last time.
Comparing new and old, A11 = J2 (5) vs. A11 =
Since it is J1 (7, 8), in this case A11 = J1
Create a command that becomes (7, 8).

If, for example, the data indicated as new is a new line setting, a command for releasing the connection between A11 and J2 (5) is created. The reverse command created in step S5 is recorded in the reverse command recording unit 16 in step S6.

Process S7 In process S7, it is determined whether or not all the settings have been completed. If NO, the process returns to process S1 and S1 to S6 are repeated. In the embodiment, the intra-station transmission line J2 is input from the input unit 11.
Data, LINK (J2 (5), LAB (10
0)) is input and recorded in step S2 as shown in FIG. 4, and a command is created and recorded in step S3.
In the process S5, a command of J1 (7,8) = LAC (5,6) is created and recorded.

Thereafter, a command is created for the TDM device of the next station B. After all commands are finished,
When a command is sent from the input unit 11, I / O1
The command recorded in the command recording unit 14 is sent via 7 to set the line between the terminals A11 and B11.

When it is desired to restore the original state for some reason, the reverse command recorded in the reverse command recording unit 16 is transmitted when the reverse command is transmitted from the input unit 11. And the terminal A11 that was previously set
And the line setting state between C11 and C11 is restored.

In the embodiment, in steps S5 and S6,
The reverse command was created and recorded each time new data was input, but after the creation of the new command, the reverse command may be created by reading the data from the line setting section as needed. Good.

In the embodiment, the current and previous line setting statuses are recorded for all the set lines, but the previous line setting status is recorded only for necessary lines as necessary. Is recorded, the memory capacity of the line setting status recording unit can be significantly reduced.

Although one embodiment of the present invention has been described above, the present invention is not limited to this embodiment, and various modifications can be made according to the gist of the invention.

[0030]

As described above, according to the present invention, the following effects can be obtained. It is designed to record the current and previous settings of the line settings, and to create and record the reverse command that restores the previously set line settings from the recorded data. It is only necessary to send the reverse command that has been issued, and it is possible to reduce both the work amount and the work time.

Further, since the line setting status that was set last time is recorded as needed, the capacity of the memory for recording the line setting status can be reduced.
