Description

C658:2025 is designed to prevent performance-degrading Unacceptable Interference within Customer Cabling that carries Legacy Systems (e.g. ADSL2+ technology) and/or Next Generation Broadband Systems (e.g. VDSL2 technology, G.fast).

The Industry Code is in three Parts:

  • Part 1 requires Next Generation Broadband Systems not to emit Unacceptable Excess Power and not to cause Unacceptable Interference to other Higher Priority Deployment Class Systems or to Legacy Systems in a Shared Cable Bundle.
  • Part 2 defines the detailed technical methods and calculations required to demonstrate those requirements are met.
  • Part 3 provides a list of defined Deployment Classes and a set of Appendices, each containing a detailed specification for a Deployment Class. It also describes the path to deemed compliance by these Deployment Class Systems.
