Abstract:
A terminal station in a synchronous communication network where data are exchanged in units of frames including an overhead for storing a control signal, comprising:extracting means for extracting from a received overhead information indicating request contents needed to execute a process of automatically bridging a working line and a protection line; mismatching judging means for judging mismatching between the work/protection line bridging mode of a terminal station transmitting the information and the work/protection line bridging mode of the own terminal station by judging whether or not the request contents of the information are used in the work/protection line bridging mode of the own station; automatic bridging means for matching the work/protection line bridging mode of the terminal station transmitting the information with the work/protection line bridging mode of the own terminal station based on the judgment result of the mismatching judging means; wherein said synchronous communication network is a SONET or SDH network; wherein said information are K bytes in a SONET or SDH network; and wherein said mismatching judging means judges mismatching between revertive/non-revertive modes.
