This standard specifies the design requirements, basic requirements of communication system route and section design, microwave station design and other technical requirements of relay communication circuit of PDH (Plesiochronous Digital Hierarchy)and SDH (Synchronous Digital Hierarchy) digital microwave.
This standard is applicable to the PDH microwave communication trunk engineering of capacity in Secondary order or more and trunk engineering design of inter-provincial and province range SDH microwave relay communication. And the design for extension, reconstruction project and small scale microwave communication project may also refers to this standard.
