Abstract: An apparatus for switching an OTH(Optical Transport Hierarchy) signal frame in an ATCA platform is provided to switch a large switching capacity and provide a multicast and ADM(Add and Drop Multiplexer) function to provide the same function as that of an existing SDH switch. A processor unit(200) is connected with a fabric interface unit of an ATCA(Advanced Telecom Computing Architecture) platform and controls ODU data received through an input port. An ethernet controller controls ethernet communication to the fabric interface unit. A cross point switch unit(220) is connected with a line card, an input/output unit of the ATCA platform, to cross-switch a 2.5Gbps signal between node slots. A chip set driver signal generating and controlling unit(230) is implemented as a circuit configuration for a control signal required for each function part for implementing an OTH unit switch, an address decoding logic for a bus with the processor unit, and a circuit of a processor bus converter for a processor connection unit of a switch element. A back board connection unit(240) uses a double star structure based on a switch slot including the fabric interface unit, and connects a management channel for managing each line card slot to a base channel to interface the 2.5Gbps signal. A duplex function part(250) interchangeably mounts/dismounts two switch units in the ATCA platform, performs switching on the switch units due to a failure, and generates a control signal to allow each line unit to select one of two received signals.
