Seminar "ISDN - Protocols" (duration: 2 days)

The seminar offers vendor and provider independent technical special know-how about ITU-T and ETSI interface definitions and D channel signalling protocols of the Euro-ISDN, as it is supported in Austria and other countries providing Euro-ISDN services. Protocol details down to bit level with 'real-live' protocol scenarios build the base of this seminar.


WHY you should attend:

  • because you need protocol specific knowledge to implement an ISDN system
  • because you are interested in standards and protocols of ISDN interfaces
  • because you need special knowledge about ISDN for troubleshooting

Your  PREVIOUS KNOWLEDGE:

  • Knowledge about ISDN (Euro-ISDN, bearer and supplementary services, applications), general knowledge about protocol mechanisms
