G.992.3 vs G.992.1
« on: May 09, 2019, 07:08:19 PM »

I was looking for a concise but complete list of the protocol improvements made in G.992.3 over its predecessor. (Every v2 should be wonderful, because you have so many opportunities plus the experience of your mistakes) I thought for some reason that there was such a thing in the opening sections of G.992.3 but I can’t see it.

Could someone help point the way to me? anyone know where I might find such a list?

See g.dmt.bis

Bis, I think refers to extended frequency.

No new protocols as G.dmt I think.

G.dmt.bis was the temporary, common, name used whilst the ITU-T G.992.3 recommendation was being developed.

I went to the ITU-T G series recommendations and checked the initial publication of G.992.3 (July 2002) to see if there was an introduction (or appendix) which listed the improvements over the G.992.1 recommendation. There was none.  :(

I'm not sure were else to check.

Of topic I think but @Weaver would love this one.

One heavy duty read. I'll keep looking.

It is there in the G.992.3 (04/2009) PDF. It's very near the start, in the Summary section, on the 4th page of the PDF (the page is numbered ii).

Thank you. I don't know how I missed that.  :-[

I do you and I were looking after the contents, never noticed there was something vital before them.
