Foreword

This standard replaces GB/T 13159-1991 "digital microwave relay systems Networking technical requirements." This standard compared with GB/T 13159-1991, the main modifications are as follows. --- Modify the standard name, delete the original title of "relay", and modify the corresponding English name; --- Original standard annotated into the preamble; --- Original standard Chapter 1 of the title was changed to "Range"; --- Original standard Chapter 2 title was changed to "normative references", and updates the reference number and name of the file; --- Chapter 5 original standard exists suspension segment, the new 5.1 "Capacity definition and classification", the content of the original standard capacity classified into 5.1; --- Original standard 5.2 and 5.3 combined, entitled "working band and RF channel configuration," according to specific technical indicators to make the actual device Updated with the situation and the relevant national regulations; 6.1 --- increase title "64kbit/s"; --- Chapter 7 of the proposed increase for FE/GE interfaces; --- Chapter 8, delete the original sub-section to increase the "digital trunk microwave system IF frequencies of 70MHz or should 140MHz". The standard proposed by the Ministry of Industry and Information Technology of the People's Republic of China. The standard by the China Communications Standards Association is responsible for centralized. This standard was drafted. Ministry of Information Industry Telecommunications Research Institute. The main drafters of this standard. Dong Xiao Lu, Zhang Li. This standard replaces the standards previously issued as follows. --- GB/T 13159-1991. Digital microwave communication systems Networking technical requirements

1 Scope

This standard specifies the large, medium and small-capacity digital microwave communication system into the national public telephone networks and private networks, skills that must be met Surgery requirements, but also provides 4GHz and 6GHz frequency band for the route and the minimum capacity limit series of national public telephone network. This standard applies to large, medium and small-capacity digital microwave communication system. This standard applies to digital transmission and digital transmission of international domestic trunk and feeder lines and exchange end offices and 64kbit/s users.

2 Normative references

The following documents contain provisions which, through reference in this standard and become the standard terms. For dated references, subsequent Amendments (not including errata content) or revisions do not apply to this standard, however, encourage the parties to the agreement are based on research Whether the latest versions of these documents. For undated reference documents, the latest versions apply to this standard. GB/T 7611 series digital network bit rate electrical interface characteristics

3 hypothetical reference digital channels and hypothetical reference digital section

3.1 is assumed that the circuit quality grading reference connection Figure 1 shows a 27500km of 64kbit/s hypothetical reference connection of five components. In accordance with the error performance of each part, you can Digital circuit is divided into three levels, namely high, medium, and user-level circuit. FIG. 1 is assumed grading reference circuit quality digital connection Digital microwave transmission channel is applied to one channel constituting these digital circuits, but also the future of digital ISDN connection component. Based digital microwave channels in the hypothetical reference connection position, are referred to as advanced, intermediate and user-level digital microwave channels. Advanced Digital Microwave digital transmission channel is mainly used for international and domestic trunk digital transmission; intermediate digital microwave channel is mainly used for domestic short-range digital Transmission; user-level digital channel is mainly used for local digital microwave digital transmission end office and 64kbit/s between users of the exchange. 3.2 Advanced for constituting part of m1 2500 k hypothetical reference digital path The length of the hypothetical reference digital channel capacity in the second group of more than meet the advanced performance requirements of 2500km. Each direction of transmission of the channel group contains 9 standard series of digital multiplexing (multiplexing and tapping) equipment. The channel contains exactly the same length of microwave digital section 9 of the like. ......
