Comprehensive AI Experiment

Which statement correctly describes the sequence of signal flow from the SDH interface to the cross-connect unit?

  • A SPI<>RST<>MST<>MSP<>MSA<>HPT
  • B SPI<>MST<>RST<>MSA<>MSP<>HPT
  • C SPT<>MST<>MSA<>RST<>MSP<>HPT
  • D SPI<>RST<>MSA<>MSP<>MST<>HPT
Explanation

The SDH transport terminal function processes an incoming STM-N signal through SPI, RST, MST, MSP, and MSA before higher-order path termination presents the high-order path to the cross-connect function. ITU-T G.783 identifies these transport-terminal functions in that order.
