欠点を有している。 Conventionally, when initializing a communication path, the exchange processing device has adopted a method of completely suspending the exchange processing, restoring the communication path device and initializing the related programs, and then resuming the exchange processing. was. However, this method has the disadvantage that it takes a lot of time to restore the communication path equipment, and the interruption time of the switching process becomes longer.
本発明の目的は、かかる従来の欠点を解消し、
復旧すべき通話路装置の復旧制御を交換処理系と

る。 The purpose of the present invention is to eliminate such conventional drawbacks,
A communication path recovery method is proposed in which the recovery control of the communication path device to be restored is executed in a processing system separate from the switching processing system, and the switching processing system is able to resume switching processing in a short time using the communication path device that does not require recovery. This is what we provide.

る。以下、図面により本発明を詳述する。 The gist of the invention is as follows. The communication path device information determined by the switching processing system to be restored is stored in the storage device of the recovery processing system, and the recovery processing system executes the restoration of the communication path using this recovery path device information and ends the execution (completion). At this point, an instruction is given to the exchange processing system to incorporate it into the exchange process. Hereinafter, the present invention will be explained in detail with reference to the drawings.

に復旧処理装置９を起動する。 The figure shows an embodiment of the present invention. In the figure, the exchange processing system 20 consists of an exchange processing device 7 and an exchange storage device 8. The recovery processing system 30 includes a recovery processing device 9 and a recovery storage device 10. In normal times, the replacement processing system 20 executes the replacement operation, and the recovery processing system 30 is in a state where it receives a startup instruction from the replacement processing system 20. During the exchange operation, the subscriber 2 and the trunk device 1 are in various states via the exchange switch 3, but if a failure occurs in the exchange that requires initialization of these path devices, the exchange processing device 7 sends the scanning device 6 The communication path device information to be restored is stored in the recovery storage device 1 based on the communication path device status read by the recovery storage device 1 and the data stored in the exchange storage device 8.
0 and recorded in the exchange storage device 8. Further, when initializing the data recorded in the exchange storage device 8, the communication path to be restored is initially set as unusable, and the exchange processing device 7 restarts the exchange operation and starts the recovery processing device 9. .

ため問題とならない。 The recovery processing device 9 reads the communication path information to be restored from the recovery recording device 10, executes the recovery of the communication path via the trunk control device 4 and the switch control device 5, and notifies the exchange processing device 7 when the restoration is completed. do. Based on this signal (control signal), the exchange processing device 7 determines the restored communication path (device) from the exchange storage device 8, incorporates it into the exchange process, and shifts to a normal operating state. During the transition period until the transition is complete, unrecovered channel devices will remain unusable and the exchange process will be executed, but the proportion of unrestored channel devices to all channel devices will be approximately 1/10. This is not a problem as it is low.

能である。 Further, the switch control device 5 and the trunk control device 4 are provided with a conflict prevention function for control requests from the exchange processing device 7 and the recovery processing device 9. In this embodiment, the recovery processing system is shown as a separate device from the replacement processing system, but if time-division multiplexing is possible, the same processing device may be used to give the recovery processing a lower priority than the replacement processing. It is also possible to execute

遂次組込み使用可能となる利点を持つ。 According to the present invention, since the restoration processing time of the communication path device, which occupies most of the interruption time in the exchange processing, is removed, the interruption time in the exchange processing can be greatly reduced. Furthermore, even during the restoration process, the replacement process can be performed using the normal channel device, and even after the restoration is completed, there is an advantage that the restored channel device can be successively installed and used.

In the method for restoring the communication path of a telephone exchange using storage program control in the event of an exchange failure, a switching processing system and a recovery processing system are provided, and the recovery processing system is kept on standby during normal times. The switching processing system performs the switching process, and when a switch failure occurs, the recovery channel device information is stored from the switching processing system to the storage device of the recovery processing system, and the recovery processing system performs the recovery process. In this case, the switching processing system restarts the switching process using a channel device other than the recovery channel device, and when the recovery operation is completed in the recovery processing system, the switching processing system sequentially reassembles the restored channel device into the switching processing system. A method for restoring a call path that requires a slow transition to a normal state.
