2014 TNO Telco Conference on DSL


[link to this post]
 
I found some interesting documents from this year's TNO "DSL Seminar" conference. If you want to see what Telco engineers are talking to each other about, have a look (it is largely about vectoring & G.fast).

Included are some presentations on
- Results from the BT/Huawei trial of G.fast
- Extra vectoring functionality for G.fast, from both Huawei and Alcatel
- Deployment studies for G.fast/FTTdp, covering Holland and Amsterdam
- Vectored VDSL2 results from Swisscom
- Vectored VDSL2 strategies for Belgium & Holland (Belgacom/KPN)

The best way to get hold of the documents is to google the following: "site:dslseminar.nl/wp-content/uploads" and you should see 26 PDF files.

Maybe that was too much for some of you?

Flushed with my success at finding those documents, I tried again for another conference. Turns out there's plenty more to keep you up way beyond bedtime...

This time from a G.fast-specific conference in May. There's a lot more technical information that is specific to G.fast, while (predictably) there is some overlap with the other set of presentations.

Google "site:uppersideconferences.net/g-fast-summit2014/pres-gfast2014" and you'll find another 20+ presentations.

I didn't realise that BT was one of the original prime movers for G.fast. From reading through a few of these presentations (eg from the serious effort being put into things like fair-sharing of the reverse power, etc), I'm getting more convinced that we'll see this stuff rolled out by them too.

G.fast is a digital subscriber line (DSL) standard under development by the ITU-T likely to deliver speeds of 200 Mbit/s to 500 Mbit/s. In exceptional circumstances, speeds could approach 1 Gbit/s. High speeds are only achieved over very short loops (shorter than 250 m.) It is a further development of technology used in VDSL2, however it is optimized for shorter distances and will not replace VDSL2 at larger distances.

Formal specifications have been drafted as ITU-T G.9700 and G.9701, and are expected to be ratified in April 2014. Development was coordinated with the Broadband Forum's FTTdp (fiber to the distribution point) project. The name G.fast is a recursive acronym for fast access to subscriber terminals; the letter G stands for the ITU-T G series of recommendations. Limited demonstration hardware was demonstrated in mid-2013. Commercial hardware is expected in 2015 or 2016.

There is a lot a development work that BT produces. For example: they were heavily involved in the VDSL standard setting and carried out the definition, development, proving and testing of the DMT modulation scheme used in VDSL2.

Certainly is for me, I rely on people like you just to tell us the basics.
