ABSTRACT:
An SDH/PDH monitoring and integrating apparatus collects control data generated in a monitoring unit employed in each PDH radio apparatus in a PDH communication network, transforms the control data into a control command that can be processed in an SDH communication network and transmits the control command to the SDH communication network. The control command transmitted to the SDH communication network arrives at an operation system by way of components such as a DCC (Digital Communication Channel), a monitoring unit employed in an SDH radio apparatus or employed in an SDH transmission apparatus and an X.25 network. The operation system extracts control data generated in the PDH communication network from the control command, executing the same processing as that of the conventional PDH monitoring panel for the extracted control data.
