So I finally scheduled it after picking up the Self Study Cisco Press Books almost one year ago. Studying pretty hard with the simulators and the actual gear for the past 3 months consistantly hopefully will pay off.
I'm still reviewing WAN protocols....Frame Relay, and PPP seem to be so easy and straight forward. ISDN on the other hand has so many minor details...Should I be worried??? As long as I can setup a router to accept ISDN traffic i should be ok I hope....
What do you think???
