Hi there,
I'm studying for my CCNA certificate. I have a question and I hope someone can tell me if I understand this right. ATM is a asynchronous transfer mode protocol. Serial interfaces like HSSI (layer 1 DCE or DTE) use a synchronous transfer mode, becaus the high speed must be timed. For example RS-232 this is not neccessary because of the low tranfer speeds (19.2 Kbps). What I would like to know is this; ATM is not using any sort of timing (it's called asynchronous), but still is capable of those high speeds (T1 up to OC-48)? Then howcome there is no timing needed? Or do I see this in a wrong way? Thanks in advance,
