  • really nice, even without beeing a native speaker, your explanations are easy to understand. thanks, this helped me :)

  • nigga you know your sh**

  • Good information - you've done the hardest part right-the knowledge, but the Name of the video & Tags are not conclusive, thats why no body is able to find your videos

  • Since there's no description available and I always forget acronyms, I wrote this Summary of Terms and Concepts for when I re-watch this later:

    ISDN = Integrated Services Digital Network Series E - Equipment already in existence  I - ISDN "Ideas" aspects/interfaces Q - Signaling

    PSTN = Public Switched Telephone Network

    BRI/PRI - Basic/Primary Rate Interface

    UNI = User network Interfaces

    T1 and E1 is part of PRI
