  1. WANS and ROUTERS Presented by Les McLellan Dean Whittaker Sandy Workman

  2. WANS and ROUTERS • What is a WAN? • WAN Devices • WAN Standards • WAN Technologies • What is a Router ? • Summary

  3. What is a WAN? • A Data Communications Network • Network Services provided by PTO’s • Relatively broad geographic area • Serial connections of various types and speeds • Provide full and part time connectivity • Technologies function at the lower three layers of the OSI Model

  4. Wide Area Network Devices • Routers • WAN Bandwidth Switches • Modems • Comms Servers

  5. WAN Standards • Defined and Managed by recognized authorities • WAN’ s use the OSI reference Model • WAN Physical Layer standards specify the interface • WAN data Link protocols

  6. The WAN Physical Layer • EIA/TIA 232 • EIA/TIA 449 • V 24 • V 35 • X 21 • G 703 • EIA-530

  7. Serial Interface Adaptor Cables

  8. The WAN Data Link Layer • High Level Data Link Control (HDLC) • Frame Relay • Point to Point Protocol (PPP) • Serial Line Interface Protocol (SLIP) • Cisco / IETF • ISDN

  9. WAN Technologies • Dedicated Lines • Switched Connections • (Circuit Switched) • (Packet Switched) • Other WAN Technologies

  10. Dedicated Lines • T1 – 1.544 Mbps • T3 – 44.736 Mbps • E1 – 2.048 Mbps • E3 – 34.368 Mbps • Other Bandwidths are also available

  11. Circuit Switched POTS ISDN Packet Switched X 25 Frame Relay ATM SMDS Switched Connections

  12. Other WAN Services • Dial Up Modems • Cable Modems • Wireless

  13. ROUTERS • Internal Components

  14. The Function of a Router

  15. WANS and ROUTERS • Summary • Data Communication Networks that operate over a large area using Serial Links • Routers are active intelligent nodes used to manage a network

  16. WANS and ROUTERS THE END
