  4. Objectives • ISDN concepts • ISDN configuration • DDR configuration

  5. Digital Communication with ISDN

  6. ISDN Benefits

  7. ISDN Standards

  8. ISDN Access Options

  9. ISDN 3-Layer Model

  10. Q.931 Messaging-Call Setup Example

  11. Call Processing • The D channel is used to send the called number to the local ISDN switch. • The local switch uses the SS7 signaling protocol to set up a path and pass the called number to the remote ISDN switch. • The remote ISDN switch signals the destination over the D channel. • The destination ISDN NT-1 device sends the remote ISDN switch a call-connect message. • The remote ISDN switch uses SS7 to send a call-connect message to the local switch. • The local ISDN switch connects one B channel end-to-end, leaving the other B channel available for a new conversation or data transfer. Both B channels can be used simultaneously.

  25. DDR Operation

  26. DDR Operation

  27. Configuring Legacy DDR

  28. Defining Static Routes • When configuring static routes, consider the following: • By default, a static route will take precedence over a dynamic route because of its lower administrative distance. Without additional configuration, a dynamic route to a network will be ignored if a static route is present in the routing table for the same network. • To reduce the number of static route entries, define a summarized or default static route

  29. Specifying Interesting Traffic

  30. Configuring Dialer Information - PPP
