What are the encodings used for V.35 and RS-232?

Not at all sure what it is you're after; V.35 essentially is a standard for T-1 and T-3 communications, and RS-232 is a standard for Serial Communications. More info can be found HERE

i'm after the encoding used to send the data from the respective ports in order that it arrive on the other side accurately and with enough changes in data. for example i learned that rs-232 uses NRZ (non return to zero) as its encoding, but i can't find the encoding for V.35 :\

Oh. Well, NRZ is the most common with V.35, though it also supports NRZI, or Non Return to Zero Inverted. The difference is the way bit intervals are handled. While both NRZ and NRZI each use 2 different voltages for transmission, maintaining a constant voltage on each leg(which is the "Non return to Zero"; it does not cut to 0 volts) during bit intervals, NRZ uses the absolute values 0 or 1 for decoding, with 0 indicating a transition and 1 indicating no transition. NRZI on the other hand interprets the absence of data - a "space" - at the beginning of a bit interval as a transition signal, and the presence of data - a "mark" - as no transition. NRZ uses absolute values for decoding signals, NRZI uses relational values. I'm not real positive, but I believe NRZI is used mostly in large scale or mainframe IBM environments. I think it was jointly developed by IBM, Cisco, and 3Com (again not real sure, but that's as I seem to recall it; I could check it out for you, though I can't imagine why it would matter). Is that what you're after?


And forgive me, but if it is what you're after, I just gotta know - why?
