Hi, all, I attended a Cisco ATM class a few weeks at Global Knowledge (top notch instructor, Mario Bigotti, ask for him by name). I not only learned ATM, and felt very comfortable.. I realized that my knowing frame relay, especially configuing my big *ss AGS+ as a frame relay switch, really helped me to understand the concepts, configuration of ATM! Several years ago, I took a BISDN/ATM course: I stunk. ATM was mind boggling, I could not follow the lecture at all; the instructor gave me a shiny ball to play with so that I would not distburb the class. Not coincdentally, at the time, I thought frame relay was something that airplanes had. Since then, I have mastered frame relay, and this ATM course was a snap! In a sense, you can learn ATM indirectly by mastering frame relay: VPI/VCI are just like DLCI, PVC and SVC mean the same thing. A frame relay switch operates similar to an ATM switch. My nickname for ATM is now "Kick *ss Frame Relay." This has been a unpaid public service announcement. Flames to: [EMAIL PROTECTED] HTH, Charles **NOTE: New CCNA/CCDA List has been formed.
