Abstract:
1. A transmission apparatus comprising: an engine configured to receive data in units of packets having a variable length and transmit a data stream signal via a SPI4.2 (System Packet Interface level 4, Phase 2) standard interface; and a mapper configured to receive the data stream signal via the SPI4.2 standard interface and transmit data in units of TDM (Time Division Multiplexing) to a SONET (Synchronous Optical Network), wherein the engine segments each of the plurality of packets into a plurality of segments having a fixed length and multiplexes the plurality of segments into the data stream signal together with channel identification information identifying channels of the SONET, wherein the engine includes wherein the mapper maps the data stream signal in frames of the SONET based on the channel identification information, and wherein the TDM scheduler includes a first table configured to store time slot numbers of the SONET and destination path numbers in correspondence with each other; and a destination determining unit configured to determine a destination path number of the plurality of packets output from the priority scheduler by referring to the first table based on the time slot counted by the counter.
