Abstract: The disclosures provide a method and apparatus for transmitting and receiving interface signals of a distributed base station. At least one channel of Common Public Radio Interface (CPRI) signals of a distributed base station are encapsulated into optical transport unit x (OTUx) signals in a frame structure of OTUx by adopting Generic Mapping Procedure (GMP) mapping scheme, wherein the x represents a transmission capacity and wherein the OTUx is adopted for providing a bandwidth required by the at least one channel of CPRI signals, and then the OTUx signals that bear the at least one channel of CPRI signals are sent.

Abstract: Embodiments of the present disclosure relate to a method and an apparatus for probing a fronthaul topology. The method includes: sending, by a baseband device, a source route probe frame; receiving a destination route probe frame, where the destination route probe frame is formed after a first transport network device records first port information in the source route probe frame and a second transport network device records second port information in the source route probe frame; and determining, by the baseband device, probe information according to the destination route probe frame, and sending the probe information to an element management system EMS.

Abstract: Embodiments of the present invention provide a data processing method, a communications board and a device. The method includes: acquiring, by a first communications board, an optical channel data unit ODU data flow; performing, by the first communications board, slicing processing on the ODU data flow according to a fixed frame frequency, so as to obtain various slices, where each slice includes a section of continuous ODU data in the ODU data flow; separately encapsulating, by the first communications board, each slice into an Ethernet frame; and sending, by the first communications board, each Ethernet frame to a time division multiplexing TDM service switching module in an Ethernet switching chip, so that the TDM service switching module sends each Ethernet frame to a second communications board to which a destination MAC address carried in the Ethernet frame directs.
