The station 5B and the 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.

[0004] Reference numeral 7 denotes a line setting system. For example, when a line is set from terminal A1 to B1, a command signal is issued to designate an empty band of the transmission line 6C and connect the terminals A1 and B1 to this empty band. A command is transmitted through the transfer path 8 to make a connection.

Further, the station A is composed of multiplexing devices (TDM) 51 to 54 as shown in FIG. The TDMs 51 and 52 convert the signal from the subscriber into a TDM 53 or 54.
And TDM51 and 52 and TDM53 and 5
The multiplexing is performed on the time-division transmission lines 61 to 64 connected between the four. The TDMs 53 and 54 are
The subscriber signals transmitted from 1 to 64 are multiplexed to the transmission lines 6A and 6C, respectively.

Therefore, for example, when a request for line setting is made from the terminal A11 to the terminal B1 accommodated in the station B, the line setting system 7
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.

[0007] The TDM device that has received the command signal from the line setting system 7 connects the input / output lines 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, the conventional line setting between terminals is performed by the line setting system for all the manufacturing processes in the network for configuring the lines between terminals. A command to connect the output was sent to set the line.

If 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. And had to send a command.

Although the network configuration described in the conventional example is very simple, the configuration of the actual network 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 An object of the present invention is to provide a set line restoring device of a line setting system which can easily restore a currently set line state to a previously set line state.
