Foreword

This document is in accordance with the provisions of GB/T 1.1-2020 "Guidelines for Standardization Work Part 1: Structure and Drafting Rules of Standardization Documents" Drafting.

This document is the first part of GB/T 40786 "Telecommunications and Information Exchange Between Information Technology Systems, Low-Voltage Power Line Communication".

GB/T 40786 has released the following parts.

---Part 1: Physical layer specification;

---Part 2: Data link layer specification.

Introduction

GB/T 40786 "Telecommunications and Information Exchanges Between Information Technology Systems, Low-Voltage Power Line Communication" draws on international mainstream standards Framing and data transmission methods and protocol architecture, mainly for broadband power line communication network networking, management and maintenance, security mechanisms, neighbor interference agreements The part of adjustment, resource scheduling, etc. is described. This document is intended to be composed of two parts.

---Part 1: Physical layer specification. The purpose is to standardize the physics that is applicable to low-voltage power line communication technology in complex and harsh environments. Layer protocol.

---Part 2: Data link layer specification. The purpose is to standardize broadband low-voltage power line communication network topology, equipment data link layer agreement Protocol stack structure, data link layer frame format and management message format, beacon-based competition and non-competition channel access mechanism, network Low-voltage power line communication such as network access and exit mechanisms, network management and maintenance procedures, routing and topology management protocols, and security mechanisms Technical content.
