Foreword
This standard is one of a series of broadband customer network standards based on public telecommunication networks. This series of standards consists of the following standards.
---Broadband customer network networking technology based on public telecommunication network requires communication and integration of high-speed visible light communication (GB/T 38832-
2020);
---Broadband customer network networking technology based on public telecommunication networks requires power line networking (GB/T 33854-2017);
---Broadband customer network networking technology based on public telecommunications networks requires wired networking of common media;
---Broadband customer network networking technology based on public telecommunication networks requires networking based on coaxial cables.
This standard was drafted in accordance with the rules given in GB/T 1.1-2009.
This standard uses the redrafting method to refer to ITU-TG.9992 "Indoor optical camera communication transceiver system architecture, physical layer and data
According to the "Link Layer Specification", the degree of consistency with ITU-TG.9992 is non-equivalent.
Please note that some of the contents of this document may involve patents. The issuing agency of this document is not responsible for identifying these patents.
This standard was proposed by the Ministry of Industry and Information Technology of the People's Republic of China.
This standard is under the jurisdiction of the National Communication Standardization Technical Committee (SAC/TC485).
Drafting organizations of this standard. China Academy of Information and Communications Technology, China Information and Communications Technology Group Co., Ltd., ZTE Corporation.

Broadband customer network networking based on public telecommunication network
Technical requirements for visible light imaging communication
1 Scope
This standard specifies the system architecture and reference model, physical layer (PHY) and data link layer of a visible light imaging communication (OCC) transceiver
(DLL) specification.
This standard applies to OCC equipment under the broadband customer network environment based on the public telecommunications network, and the private telecommunications network can also be used as a reference.

3 Terms and definitions
The following terms and definitions apply to this document.
3.1
Aliendomain
Any non-visible light imaging communication network node group connected to the same medium or working in a very close range.
Note. The bridging function to the external domain and the coordination function with the external domain in order to avoid mutual interference are not within the scope of this standard.
3.2
Domain
A visible light imaging communication network, including the domain master node and all those nodes registered to the same domain master node.
Note. In the scope of this standard, the use of the term "domain" without a qualifier refers to the "visible light imaging communication network domain". Other qualifiers can be used for "domain".
3.3
Domain management node domainmaster; DM
A node that supports the domain master function of managing (coordinating) all other nodes in the same domain (that is, allocating bandwidth resources and managing priority). area
Only one active domain master node is allowed in, and all nodes in the domain are managed (coordinated) by a single domain master node.
3.4
Endpointnode
Distinguish between domain master node function and non-domain master node function, or used to distinguish one-way broadcast node function and non-one-way broadcast node function.
3.5
Global management node globalmaster; GM
Provides coordination functions between different domains (e.g., communication resources, the strategy of the domain master), and can also be transmitted by a remote management system (e.g.,
Broadband Forum CPEWAN Management Protocol) initiated management functions to support broadband access.
