GB/T 21645.3-2009Technical requirements for automatically switched optical network -- Part 3: Data communication network (English PDF)

Foreword

GB/T 21645 "Automatic Switching Optical Network (ASON) Technical Requirements" consists of the following components.

- Part 1. architecture and overall requirements;

- Part 2. Terms and definitions;

- Part 3. Data communication network (DCN);

- Part 4. Signaling;

- Part 5. Routing;

- Part 6. Management Plans;

- Part 7. Automatic discovery.

This part is part 3 of GB/T 21645.

This part corresponds to ITU-TG. 7712 "Data Communication Network Architecture and Specification" (English version), the degree of consistency is non-equivalent.

The following chapters of this section are in technical content with ITU-TG. 7712 Harmony.

- Chapter 6 Management Communication Network (MCN) requires ITU-TG. 7712 of 6.1;

- Chapter 7 Signaling communication network (SCN) requires ITU-TG. 7712 of 6.2;

- Chapter 8 DCN structure and function requirements correspond to ITU-TG. 7712 Chapter 7.

This part is part of ITU-TG. The main differences in 7712 are as follows.

- in line with the specific circumstances of our country to increase the provisions of the following chapters.

Chapter 4 DCN Application;

Chapter 5 ASONDCN GENERAL REQUIREMENTS;

6.3MCN security;

7.2 SCN General requirements;

7.3.3 SCN troubleshooting;

Chapter 9 DCN Network Performance.
