FIG. 21 is a diagram showing a configuration example of a conventional transmission device. The conventional transmission apparatus includes a plurality of line interface units 6 for relaying and multiplexing signals, a plurality of control processing units 4 for controlling the operation of the line interface units 6, and a plurality of alarm processes for monitoring the state of the line interfaces 6. It is composed of part 3.

Between the plurality of line interface units 6 and the plurality of control processing units 4, and between the plurality of line interface units 6
And a plurality of alarm processing units 4 are connected by a plurality of control buses 8 and a plurality of alarm buses 7, respectively. The line interface 6, the control processing unit 4, and the alarm processing unit 3 are each packaged.

The conventional transmission device is realized by the following technique. a. The control processing unit 4 and the alarm processing unit 3 employ an architecture having a plurality of CPUs according to the processing content. The control processing unit 4 and the alarm processing unit 3 each use a CPU with a small number of bits (for example, an 8-bit CPU). In this architecture, these multiple CPUs
Are distributed. b. Multiple device memories that manage device control data
It is distributedly arranged in the U-mounted package, and a huge amount of data communication is performed between the CPU-mounted packages. c. The transmission device has a volatile operational memory for managing the current operational state and a non-volatile backup memory for simultaneously recording them. d. When removing the package of the control processing unit 4 of the transmission device, it is necessary to artificially set the package to the protect-on state (control-disabled state). e. When the power supplied to each package is turned off / on, only that package is restarted. f. If the package is inserted or removed while writing the control data to the memory, a defect in the control data occurs and the recovery thereof is insufficient. g. When a failure occurs in the transmission device, it is necessary to investigate the processing status in each processing unit (CPU package). In this case, it is necessary to perform a specialized operation such as connecting an external terminal to the package.

[0006]

However, the above-mentioned conventional transmission device has the following problems. In addition,
The following item numbers correspond to the item numbers in the above-mentioned "prior art". a. The more complicated the processing contents (multifunctional / high performance), the more CP
The number of U-mounted packages increases. As the number of packages increases, the size of the transmission device increases. Particularly, in the case of a transmission device including a shelf in which a plurality of packages are mounted, a plurality of transmission device units may be required.

Therefore, the space required for installing the transmission device increases, and the running cost also increases. Further, as the number of packages increases, the power requirement increases proportionally and the cost required for cooling the transmission device also increases. b. Multiple device memories that manage device control data
When distributed in the U-mounted package, the device control data is distributed. Therefore, the amount of data communication between the CPUs increases, and the processing speed cannot be increased. c. Since only one operational memory and one backup memory are provided, the contents of the package that carries the operational memory are initialized when the package is removed. Further, if the package fails, the recovery means has only the contents of the backup memory and the reliability is low. d. When the package of the control processing unit of the transmission device is removed, the control processing of the transmission device is disabled. For this reason,
It is necessary to suppress (protect on) the control processing in the transmission device in advance. However, since this operation needs to be performed artificially, there is a possibility that the operation may be forgotten. In this situation, if the transmission device is erroneously controlled from the outside, the transmission device is adversely affected. e. When the power supply of a package that operates in conjunction with another package is turned off / on, only that package is restarted. So after the package is restarted,
The operating status of the transmission device becomes unstable. f. There is no means for detecting a defect in the control data managed on the memory. Therefore, there is a risk of activating the transmission device with incorrect data. As a result, the operating state of the transmission device may suddenly change, which may hinder the network operation. g. When a failure occurs in the transmission device, a specific person having skill in the investigation / analysis work, and ancillary equipment such as an external terminal are required. Therefore, the failure cannot be quickly recovered.

An object of the present invention is to provide a transmission device which can be miniaturized and have high functionality. In particular, this transmission device reduces the device size, reduces the number of packages, and reduces the operating cost. Minimize the impact on the operation of the equipment when replacing the package and ensure the equipment is started. Furthermore, the control data in the device is managed reliably. They improve the reliability of the network. By providing the above-mentioned device, it is possible to solve the above-mentioned problems of the conventional transmission device.
