13 module isdn bri call

  1. 1. Completing an ISDN BRI Call
  2. 2. Objectivies <ul><li>Upon completion of this chapter, you will be able to perform the following tasks: </li></ul><ul><li>Describes the components that make up ISDN connectivity </li></ul><ul><li>Configure ISDN BRI and legacy dial_on demand routing (DDR) </li></ul><ul><li>Verify DDR operation </li></ul>

  9. 9. Configuring ISDN BRI Step 1: specify the ISDN switch type Router (config )# isdn switch_type switch _type Router (config_if)# isdn switch_type switch _type <ul><li>Specifies the type of ISDN switch with which the router communicates </li></ul><ul><li>Other configuration requirements very for specific providers </li></ul>
  10. 10. Configuring ISDN BRI (cont.) Step 2 : (optional ) Setting SPIDs Router (config_if) # isdn spid 1 spid _number [ idn ] Sets a B channel SPID required by many service providers. Router (config _if) # isdn spid 2 spid _number [ idn ] Sets a SPID for the second B channel

  13. 13. ISDN Basic Service Dial Connection DCE “ Interesting” packet arrives <ul><li>Route to Destination is determined </li></ul><ul><li>Interesting packets dictate DDR call </li></ul><ul><li>Dialer information is looked up </li></ul><ul><li>Traffic is transmitted </li></ul><ul><li>Call is terminated </li></ul>Generic DDR Operation
  14. 14. ISDN Basic Service Dial Connection DCE “ Interesting” packet arrives <ul><li>Define static routes - what route do I use? </li></ul><ul><li>Specify interesting traffic - what traffic </li></ul><ul><li>enables the links ? </li></ul><ul><li>Configure the dialer information - what number do I call ? </li></ul>Configuring Legacy DDR
