That's like asking for a network diagram on a token ring network. http://en.wikipedia.org/wiki/T568A#T568A_and_T568B_termination posted:The United States National Communication Systems Federal Telecommunications Recommendations explicitly forbid T568B, as does all US Federal guidance on new construction for the US Government. T568B is deprecated (removed) in the current TIA/EIA-568-C standard[citation needed] When I was taught (here in Australia), A was the standard one and B is the one you use for crossovers. Either way, T568A is not exactly obsolete like Token Ring or coax physical bus networks! Edit: Passed the CCNA exam last week. Had some questions that were definitely not CCNA material (checked through cert guides, looked in CCNP books). I'm guessing they were the beta unmarked questions the intro mentioned. Or maybe they are mentioned in the official 3rd edition cert guides. I studied from the 2nd edition which is from 2008. PancakeTransmission fucked around with this message at 12:00 on Jan 23, 2013 |

Since I was actually looking this topic up just a few weeks ago, here's the RFC for it. RFC 3021. It is only a proposed standard despite being written in RFC 12 years ago and being implemented by Cisco devices since 2001. I guess they're focusing more on IPv6 at this point! Imagine all the IPs that could have been saved... But I guess a lot of older hardware wouldn't support it.
