SONET/SDH transmission apparatus |
摘要 |
A SONET/SDH transmission apparatus comprises a plurality of interface units that accommodate a plurality of lines, and mesh wiring that interconnects the interface units in a mesh pattern. Each of the interface units includes a time slot interchange (TSI) unit to output a signal selected from among a plurality of signals through the TSI processing of a plurality of signals on the lines accommodated at all the interface units, a detection unit to detect alarm information on the lines accommodated at all the interface units, and a control unit to provide the TSI unit with control data reflecting protective switching operation calculated by computation of a logic circuit which virtually executes the protective switching operation to be as for the plurality of lines.
