I presume the profile will change and head upwards of 60mb down after the exchange has done its training?

at 11 attenuation, ild toss at you have no show of hitting 60. your too far for a 17a profile.

So man..  Are you really sure about that 17a profile?  Check this out..

Old is left and new is right, it literally just changed to 17a a few minutes ago

impressive.. your on one of the odd dslams that has a Max of 71680 rather than 70000, we have seen odd things happen with them..

11db attenuation, purely from DLM is a first. even if your fritz is miss-reporting (seen the newer firmwares show a 1~3db higher attenuation.


as you can see in your spectrum, distance is clearly a factor for you (note the DL 3 block, tapering off.)


i base my full figures from a chorus employee, along with what we personally have seen in the VDSL section of snap..

BMarquis: 
We have a number of conditions that must be met for your line to be switched to a 17a Spectrum profile.
If your line is on the 17a spectrum profile, but the spectrum between 8Mhz and 17Mhz is not being used, I'd be looking at your CPE.  it shouldn't report 17a unless the DSLAM is providing that, and we run 8b and 17a on independant profiles.

As for the question of 'what allows a line to be on 17a':
The current bandplan is 8b (goes without saying!)
The line is shorter than 350 meters, which is an electrical length in the 5530 Network Analyser of <7dB
DLM is in operation on that line
A Bandplan switch hasn't occured in the last 90 days (to stop bouncing between 8b+17a, while still allowing re-evaluation as/when required)

Hopefully this helps answer some questions?


by all respects, im hella surprised your on 17a, but congratulations!

Hey, I thought you'd find it interesting!

My knowledge is isn't as great as yours, what do you mean by "Purely from DLM (Dynamic Line Management?)" also I presume the DL 3 block is the new stack of yellow that's appeared that has something to do specifically with the 17a profile?

yes, the last blue block. notice the steady slope on it? thats your distance tapering it off.

your post got a mention about in the VDSL performance thread, where we discussed how you could have gotten it, including chorus's direct input on it.

http://www.geekzone.co.nz/forums.asp?forumid=90&topicid=105744&page_no=208#984690 onwards if your interested

what i was getting at however, was your line by all respects of a few assumptions we had made, was not gonna be getting 17a.
