This standard specifies the design requirements for PDH (quasi-synchronous digital series) and SDH (synchronous digital series) digital microwave relay communication circuits, basic requirements for communication system routing and cross-sectional design, and technical requirements for microwave station design. This standard is applicable to the design of new PDH microwave communication trunk line projects with secondary group capacity and above and SDH microwave relay communication inter-provincial and intra-provincial trunk line projects. The design of expansion, reconstruction projects and small microwave communication projects can be implemented as a reference.
