Description of the Related Art In a communication path apparatus, a communication path is set by writing communication path data into a communication path control memory for controlling the communication path. However, since the volatile memory is used as the channel control memory from the viewpoint of the writing speed, when the power of the channel device is turned off, the channel path data written in the channel control memory is lost. . Therefore, when the communication path device is restarted after the power supply of the communication path apparatus is turned off, it is necessary to reset the communication path from the external control device.

By resetting the path data, the time required to reset the path data can be reduced. In addition, when the operation speed of the nonvolatile memory is high, the communication path control memory is configured by the nonvolatile memory, so that the communication path data does not disappear when the power is turned off, so that the communication path data need not be reset.

通話品質が高められる。The path control to the communication path switch 11 is performed by transmitting the communication path data from the central control circuit 21 to the non-volatile communication path control memory 17 and continuously transmitting the communication path data from the non-volatile communication path memory 17. To control the path connection in a time-division manner. When the power of the communication path unit 1 and the communication path control unit 2 is turned off and then turned on for some reason, the memory and registers need to be initialized and reset in order to start up the communication path control unit 2. However, the non-volatile communication path control memory 17 of the communication path unit 1 stores the same communication path data as the contents before the power is turned off, so that the path setting of the communication path switch 11 is instantly restored to the contents before the power is turned off. It is possible to As a result, a path during a call is disabled for a momentary power interruption, thereby improving call quality.

なり、通話路パスデータの再設定時間を短縮化できる。As described above, by using the non-volatile memory for the backup of the communication path control memory, the time required for restoration after the power is turned off can be reduced by the path setting information backed up on the current magnetic disk. It can be shortened compared to the method of restoring to the original. In addition, by providing a non-volatile memory in the communication path unit, compared to the conventional method of providing a non-volatile memory for backing up the communication path data in the conventional communication path control unit, the power is automatically restored to the communication path control memory by hardware after the power is restored. The communication path data can be reset, and the time required to reset the communication path data can be reduced.

のパスが迅速に再設定される。Further, since all paths are backed up, regardless of the type of path such as a dedicated line path, a semi-fixed path, and a call rescue path, not only these but also all path information are held. In addition, since backup is always possible, which is impossible with a backup using a magnetic disk, all paths immediately before the power is turned off are quickly reset at the time of restoration after the power is turned off.

とも可能である。When a non-volatile memory is used as the communication path control memory, when the power is turned on again after the power is turned off, the communication path control memory holds the communication path data immediately before the power is turned off. There is no need to reset road path data, and the time required for system restoration can be reduced. In addition, since a non-volatile memory is used as a communication channel control memory, it is possible to configure the communication device with a smaller scale than conventional hardware. It is also possible to improve call quality.
