  1. The UCAR Physical Network Infrastructure or Why Bother to Do It Right? Presented By: James R. Van Dyke

  2. Presentation Topics • What is a Structured Cabling System? • Limitations of Cable • Terms • Topology Types • Standards • NCAR’s model of the System • NCAR Site Structures • Conclusion

  3. What is a Structured Cabling System? • Standards Based • Controlled & Organized • Documented • Fully Tested • Specific Topology

  4. Terms Used • Telecommunications Closet (TC) • Telecommunications Outlet (TO) • Main Cross-connect (MC) • Intermediate Cross-connect (IC)

  5. Limitations of Cable • Why is fiber cable used as the backbone cable? • Copper cable has a shorter distance limitation than optical fiber • In a structured system, a single fiber connection can span multiple locations

  6. Ring Topology • Redundant Paths • Longer paths to nodes • Locks-in style of topology

  7. Star Topology • Hierarchical • Can centralize to one point • Can emulate a ring

  8. Structure of the Star • Main Cross-connect • Intermediate Cross-connect • Telecommunications Closet • Telecommunications Outlet

  9. Standards • All use star Topology as preferred method • Specifies cable limitations for cable types • Twisted Pair • Fiber • Some Standards Bodies • EIA/TIA 568 • BICSI

  10. NCAR’s Model of the System

  11. ML Site Structure

  12. FL Complex Site Structure

  13. JEFFCO Site Structure

  14. Current Media Installed to T.O.’s • Two Category 3 Cables - Telephone • Four Category 5 Cables - Data 100Mbps • Two Pair Fiber Cable - Extended distance, ATM

  15. Older T.O. Installed Media • Two 3-pair Cables - Telephone • Two 3-pair Cables - Data - Retrofitted to support 10Base-T • Two pair fiber Cable - Unterminated, special use

  16. Conclusion • NCARs structured cabling system allows the following: • Concentration of equipment at central locations • Flexibility to adapt to changing connection types • High speed available with the use of fiber • Special direct connections can be installed with minimal work
