  4. Objectives

  5. Introduction to Serial Communication Transmission system encodes bits into electrical voltage using methods like NRZ-L or AMI Some of the many serial communications standards include the following: RS-232-EV.35High-Speed Serial Interface (HSSI)

  6. Time-Division Multiplexing

  7. Demarcation Point The point in the network where the responsibility of the service provider or "telco" ends.

  8. DTE-DCE

  9. Serial Connection Options

  10. DTE/DCE Interface • The DTE/DCE interface for a particular standard defines the following specifications: • Mechanical/physical - Number of pins and connector type • Electrical - Defines voltage levels for 0 and 1 • Functional - Specifies the functions that are performed by assigning meanings to each of the signaling lines in the interface • Procedural - Specifies the sequence of events for transmitting data

  11. HDLC Encapsulation

  12. Configuring HDLC Encapsulation

  13. Troubleshooting a Serial Interface

  14. Troubleshooting a Serial Interface • Five possible problem states can be identified in the interface status line of the show interface serial display: • Serial x is down, line protocol is down. • Serial x is up, line protocol is down. • Serial x is up, line protocol is up (looped). • Serial x is up, line protocol is down (disabled). • Serial x is administratively down, line protocol is down.

  15. PPP Layered Architecture

  16. PPP and the DataLink Layer

  17. PPP and the Network Layer

  18. Establishing a PPP Session

  19. PPP Operation

  20. Link Control Protocol Options

  21. PPP Configuration Options

  22. Network Control Protocol

  23. PPP Authentication Protocols

  24. PPP Authentication Protocols

  25. Password Authentication Protocol (PAP)

  26. Challenge Handshake Authentication Protocol (CHAP) CHAP provides protection against playback attack through the use of a variable challenge value that is unique and unpredictable.

  27. PPP Encapsulation and Authentication Process

  28. CHAP Authentication Process

  29. Configuring PPP

  30. Configuring PPP Authentication

  31. PAP Configuration

  32. CHAP Configuration

  33. Verifying PPP

  34. PPP Configuration Commands

  35. Debug PPP Authentication

  36. Summary
