568 c0 c1_and_c3_overview

  1. 1. ANSI/TIA-568-C SeriesHerbert V. Congdon II, PETyco Electronics
  2. 2. 568-C – Why?• ANSI mandates a 5-year life for published standards – Revised, reaffirmed or withdrawn• TIA-568B published May 2001 – >5 years ago• Many addenda since publication – 6 addenda to 568-B.1 – 10 addenda to 568-B.2 – 1 addendum to 568-B.3 page 2 / October 16, 2008
  3. 3. 568-C Series Documents• One New Standard (568-C.0) – 568-C.0 – generic structured cabling – RELEASED (October)• Three Revisions – 568-C.1 – commercial building cabling – RELEASED (October) • Office-oriented buildings – 568-C.2 – copper cabling components – expected in 2009 – 568-C.3 – fiber cabling components - PUBLISHED page 3 / October 16, 2008
  4. 4. Improvement Opportunity• Complaint: Duplicated information – Cause: Synchronizing and updating multiple documents is complicated – Solution: Centralize common information page 4 / October 16, 2008
  5. 5. Improvement Opportunity• Complaint: Lengthy development of new Standards – Cause: Creating new premise Standards is unnecessarily repetitive – Solution: Establish common information in one document page 5 / October 16, 2008
  6. 6. Improvement Opportunity• Complaint: Gaps in Standards coverage – Cause: Standards tend to be too specific in scope • Result: 568-B (for office-oriented commercial buildings) applied to non-office-oriented locations – Solution: Start with common information applicable everywhere, then manage exceptions and allowances specific to the premise page 6 / October 16, 2008
  7. 7. Solution: A Generic Cabling Standard• A new standard for generic cabling - 568-C.0, Generic Telecommunications Cabling for Customer Premises – The foundation for future Standards – The cabling Standard when documents specific to a premises are not available – Consolidates common information in one document • Content from 568-B.1 & addenda split between C.0 and C.1 page 7 / October 16, 2008
  8. 8. Splitting 568-B.1 568-B.1 (94 pgs)568-C.0 568-C.1Generic CBC(~60 pgs) (~35 pgs) page 8 / October 16, 2008
  9. 9. Other TR-42 Documents• Starting the processes to make other documents more generic – Ex: removing commercial building focus from Pathways and Spaces• Segregating documents into three categories: – Common Standards – generically applicable documents – Premise Standards – specific to one type of premise – Component Standards – performance requirement• Intended Customers – End-users, contractors, designers: Common and Premise Standards – Manufacturers: Component Standards page 9 / October 16, 2008
  10. 10. • Three Document Types – Common Standards • Generic • Pathways & Spaces • Administration, etc. – Premise Standards • Commercial Building • Residential • Data Centers, etc. – Component Standards • Copper • Optical Fiber page 10 / October 16, 2008
  11. 11. Looking Forward• Over the next 3-5 years – Other premises Standards will be revised to acknowledge 568-C.0 • List appropriate exceptions and allowances – Existing common Standards modified to broaden scope • Replace “commercial building” focus and terminology • Become more generic in nature• New Standards will be built on the foundation of 568-C.0 page 11 / October 16, 2008
