There is white papers on ddDLM; however no clear details per chorus's choice of implentation.

Now that you've done your wiring improvements, it might be worth getting your ISP to reset DLM on your line so that it can re-train based on your improved line conditions.

 

 

With ddDLM, resetting of port may no longer be necessary based on my own observation. ddDLM will detect that the line condition has improved and will gradually increase the sync speed. ddDLM usually make speed adjustment after sitting in the background monitoring for about 3 days.

 


Unlike the old DLM, ddDLM it is fairly "dynamic". It does not stay in one spot for long. It is constantly adjusting speed based on line condition. This is my own observation based on monitoring ddDLM behaviour since it went live on my line in late April. ddDLM's behaviour sort of makes sense as I believe the goal is get close to optimal performance at any point in time.

 


There is no white paper on ddDLM so the above is based on anecdotal evidence.

 

 

 

 

This is true, assuming that sholdowa's connection is using ddDLM of course.

ddDLM is enabled on 99.9% of lines now.

hio77: There is white papers on ddDLM; however no clear details per chorus's choice of implentation.

 

Is the white paper available for public consumption or is it RSP only?

 

Interested to have a read if it is available for public consumption.

ddDLM is a product created by AL not chorus; as such a public document, but targeted at non public audiences. (Great for understanding the inner workings of the DSLAM's though)

 

Chorus simply pick and choose the design for it to confirm to.

 

 

 

I'll see if i can't dig it up, is a 600+ page DSLAM version document, where a subsection relates to ddDLM.

Looks like a spark line? Happy to take a look deeper...

 

 

 

On VDSL, you don't have the option of turning interleaving off, overall PTM is better for latency than ATM. thus it Should be better.

I've just recently switched from spark to bigpipe. do you think switching back to adsl might be better for gaming? or maybe getting a masterjack installed?

why are you using a standard filter if you are on naked VDSL? remove that for a start.

 

have you tried the other jack point to see if its better?

 

next thing to do would be to modify the wiring so that only one jack point works, ie give yourself a master jack point. a single run from the ETP to the jack point to eliminate any wiring issues in the house.
