摘要： A method for quickly diagnosing inter-communication problem of digital subscriber line transceivers, which records the interactive messages between central office xDSL terminal unit (xTU-C) and remote xDSL terminal unit (xTU-R), amends specific message of said interactive messages, executes interactive test utilizing amended message, and analyzes the result of said test to confirm the reason of inter-communication problem. The embodiments also provide an apparatus for quickly diagnosing inter-communication problem of digital subscriber line transceivers. The embodiments efficiently resolve the inter-communication problem between xTU-C and xTU-R which are different xDSL transceivers, provide convenience to telecommunication service provider and telecommunication device maintenance personnel, and save the cost. Device maintenance personnel can quickly, efficiently and accurately resolve inter-communication problem of xDSL devices, so as to simplify processing flow, reduce workload and difficulty, save substantive cost, and improve efficiency.

摘要： A system and method for diagnosing the connectivity of DSL transceiver are disclosed. The DSL transceiver comprises xTU-C and xTR-R, and the system comprises message collection module and fault analysis module. The message collection module collects and stores the interworking messages of the xTU-C and xTR-R in the initialization process; The fault analysis module analyses the messages which have been collected and stored, and then determines the conclusion about the connectivity of DSL. The invention resolves the connectivity of the different xTU-C and xTR-R, simplifies the process flow, improves the efficiency, and reduces the cost. Furthermore, the device For diagnosing the connectivity of DSL transceiver is disclosed.

摘要： This application provides a data frame fragmentation method, a data frame parsing method, and a related device. An OLT generates an original data frame. The original data frame includes a frame header and a packet. If a length of the frame header is greater than a first preset value, the OLT performs fragmentation on the frame header to obtain a target data frame. A length of each subframe header after the frame header is fragmented is less than or equal to the first preset value. The target data frame includes a plurality of codewords. At least one codeword includes a first field. Each codeword includes a second field. The at least one codeword further includes a third field. The first field is used for carrying the subframe header and a first packet having a low priority. The second field is used for carrying a check code. The third field is used for carrying a second packet having a high priority. A sending order of the first packet is after a subframe header with a front most sending order, and the sending order of the first packet is before a sending order of at least one subframe header. Further, the OLT sends the target data frame to an optical network unit ONU.
