Baud =/= frames per second

"The data frame rate (baud rate) is 4,000 frames per second." Huh? Baud is symbols per second, not frames. How many symbols are sent over T1.413? - Theaveng ( talk) 18:32, 27 November 2007 (UTC) reply

Right, I think nowdays we would just say the baud rate is 4000 per second. Times 254 subcarriers times 15 bits per subcarrier symbol (3810 bits per baud) equals the 15.24 Mbit/s rate. This is just the modulation, and several more layers (e.g. ATM and an adaption layer, I guess) would be required before one gets to a "packet" or Ethernet frame equivalent, so very different. Needs be explained much better, and with sources. W Nowicki ( talk) 23:10, 22 September 2011 (UTC) reply

Obvious question

What happened to Issue 1???? If nobody objects, we should probably move it to a simpler name ANSI T1.413 since that seems unqiue for these many years. W Nowicki ( talk) 23:04, 22 September 2011 (UTC) reply
