BICSI January 2009

Introduction

• Herb Congdon – Chair, TIA TR-42

TR-42 Overview

Herb Congdon

TIA

• Telecommunications Industry Association

TIA

• A “full service trade association representing providers of communications and IT products and services for a global marketplace” • An ANSI-accredited Standards body in information and communications technology (ICT) • Over 10 main formulating plenary committees and several TAGs for international Standards bodies • We’re #4!!

TIA - Standards

• Membership – Member Companies – Former Member Companies – Individuals (ECP) – Liaisons – Government

TIA TR-42

• “Original Nine” Subcommittees – 42.1 Commercial Building Cabling – 42.2 Residential – 42.3 Pathways & Spaces – 42.4 Outside Plant – 42.5 Terms, Definitions and Abbreviations – 42.6 Administration – 42.7 Copper Components – 42.8 Optical Fiber Components – 42.9 Industrial

How TR-42 Works

Herb Congdon

Process

• New Proposals or Timed Actions • Task Group • Draft Developed • Documents Balloted • Consensus-based Resolution • Re-ballot As Necessary • Documents Released for Publication • Documents Approved for Publication

The NEW 568-C.0 Standard

Herb Congdon

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• ANSI mandates a 5-year life for published standards – Revised, reaffirmed or withdrawn • TIA-568B published May 2001 – 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

Improvement Opportunity

• Complaint: Duplicated information – Cause: Synchronizing and updating multiple documents is complicated – Solution: Centralize common information

Improvement Opportunity

• Complaint: Lengthy development of new Standards – Cause: Creating new premise Standards is unnecessarily repetitive – Solution: Establish common information in one document

Improvement Opportunity

• Complaint: Gaps in Standards Coverage – Cause: Standards tend to be too specific – Solution: Start with common information applicable everywhere, then manage exceptions and allowances specific to the premise

The Plan

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

568-C.0

Generic (~60 pgs)

Splitting 568-B.1

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

568-C Series Documents

• 568-C.0 – generic structured cabling – RELEASED (October) • 568-C.1 – commercial building cabling – RELEASED (October) • 568-C.2 – copper cabling components – expected in 2009 • 568-C.3 – fiber cabling components PUBLISHED

568-C.0 Generic Cabling

• 568-C.0 Establishes How a Star Network Topology Is Constructed – Does not need to be repeated in every document – Premise standards define appropriate allowances and exceptions

568-C.0 Generic Cabling

• 568-C.0 Establishes Cabling Requirements – Applicable to all premise Standards unless noted as an exception or allowance

568-C.0 Generic Cabling

568-C.0 – Generic Cabling

• 568-C.0 Incorporates some of the 568-B.1 Addenda – Centralized cabling, patch cord bend radius, etc.

• 568-C.0 Collected Common Information from 568-B.1 and others – Choosing media, Cabling lengths – Bonding and grounding, Polarity – Installation requirements – Application support tables – Optical fiber testing & limits • NOTE: balanced twisted-pair testing and limits will be in 568 C.2

568-C.0 – Technical Changes

• Installation minimum bend radius for balanced twisted-pair cable – Changed to 4x cable OD for both shielded and unshielded • Note: Worst case minimum bend radius is now 1.5 inches (not 1.0 inch) since the largest allowable cable OD is 0.354 inches (per 568-B.2-11) • Adds Augmented Category 6 (shielded and unshielded) as a recognized medium

568-C.0 – Technical Changes

• Patch cable bend radius for balanced twisted-pair cabling – Changed to “1x cable OD” from “0.25 inches” • Single-mode optical fiber allowed in the horizontal • Simplex optical fiber
