Foreword

This standard was drafted in accordance with GB/T 1.1-2009 given rules.

This standard uses the translation method identical with ISO/IEC 18010:2002 "Information technology for customer premises cabling pathways and spaces," and the ISO/IEC 18010:2002/Amd1.2005 Content "multi-user path and space" directly into the provisions of this standard. Amendments Terms have been involved through the vertical wire (||) its outer margin positions were marked.

This standard mainly to do the following editorial changes.

--- Revised editorial errors;

--- Increased use text abbreviations in Chapter 3, but not listed "EMC" "HD" and "PBX";

--- Remove the 7.1 "following the path alphabetically sorted";

--- 7.1, following the original meaning of the expression "and other safety rules for equipotential bonding and grounding of the metal path, see local law Regulation "was changed to" equipotential bonding and grounding metal should follow the path of safety relevant standards in China, "the standard for ease of use and real Shi lists relevant national standards in the footnotes;

--- According to GB/T 1.1-2009 header in the format specified by modifying the header of the form table A.1.

Introduction

Communication infrastructure is an essential part of building design. Communication infrastructure may include voice, data, environmental control, security Full, audio, television, sensing, alarm, paging and other low voltage limited power and signal systems. These systems change frequently. Path and space Between the design should accommodate this dynamic behavior. The standard design of other buildings and services, such as electricity, heating, ventilation and air conditioning (HAVC) Have a significant impact.

This standard does not recommend a specific telecommunications pathways and spaces design options. Failure to describe the pros and cons between the duct system and the system tray. By the power Designer based on the corresponding letter of application and limitations appropriate choice.

This standard does not give specific requirements for paths and space dimensions. Readers should refer to the following documents.

--- China's relevant regulations and standards;

--- Telecommunications service provider rules;

--- Manufacturers guidelines.

information Technology Customer premises cabling pathways and spaces

1 Scope

This standard specifies in accordance with ISO/IEC 11801 and ISO/IEC 15018 design provides for a building or building between the inner Structure and requirements of the path of the exchange of information and telecommunications cabling space.

This standard also affects the deployment of space inside the building. This standard takes into account single-family residential and commercial buildings and multi-dwelling.

This standard does not address safety aspects of building design and fire safety measures or require special security measures to telecommunications systems.
