Could you cite a bit more detail as to how it has changed?
You mean the standard of calling a two-wire connection an RJ11, a four-wire connection an RJ14, and a six-wire connection an RJ25? The standard is still in place, but we generally call all of the RJ11s.
Do you instead mean that the use of the jack that will accept a plug with up to six wires has been supplanted by use of the eight-pin jack? Officially, meaning the standard has changed, as opposed to what this thread is about, meaning unofficial practices?
I am talking about the official standard by TIA/ANSI which specifies what and how to wire for structured cabling. This is the ANSI/TIA-568 standard and it is now in its C revision.
TIA-568-C suite of standards breakdown:
TIA-568-C.0 Generic Telecommunications Cabling for Customer Premises
TIA-568-C.1 Commercial Building Telecommunication Cabling Standards – Part 1 General Requirements
TIA-568-C.2 Balanced Twisted-Pair Telecommunications Cabling and Components Standard (release date: TBA)
TIA-568-C.3 Optical Fiber Cabling Components Standard
The TIA568C is mainly for commercial and is also generic. There is a specific standard for residential, the ANSI/TIA-570-C.
Maybe Gman did not have these in mind when he posted about industry standards but if you are looking for the appropriate standards on how and what to wire for structured cabling, data and communications then the ones I posted above are the ones to follow.
