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.
