gel joiners are the usal that should be fine.

unlikely (although snap actually strongly push their nice metal jack ended cat6 cable for from the jack to the modem.). how is the cable to the jack actually ran? is it a single line to that jack point for the DSL side? multiple jacks even not in use can cause inflictions.

it could even be a external cable fault (although alot less common).

The cable comes in from the road joined (now by me) to this (I assume network) cable installed by Chorus which goes through the roof into the lounge.
From the lounge Chorus installed a pretty nifty jack which accepts both RJ45 and RJ11, and from there to the modem is a piece of flat phone cord (RJ11 on both ends) if that make sense.

A-----1------B-----2------C

Whereas A is the box in the garage, 1 is the CAT5 installed by Chorus(brand new), B is the jack inside the house, 2 is the phone cable with RJ11 heads and C is the modem.

I removed the splitter from A to 1 as it was hooked up to another loop in the house too, since I have no use of them I thought by disconnecting them would lessen the chance of the cable acting as antenna picking up random stuff.

your diagram is a tad confusing, maybe i havent woken up enough yet.

but what i can make out of it, you have a direct cable to the jackpoint, no dasiy chaining off it, which sounds about right.

ild probably use a rj45..

sounds to me like the install is up to spec, but something certainly isnt right with your error rates.

A quick question.

As DLM drops from DLM-6 (which I started on) to DLM-1, should my attainable rate have dropped?

Gone from Sync rate of 28 to 24.5.

normally your speed will go up, but DLM may reduce your speed to be able to hold the lower latency profile stable.

moreso seen on marginal lines, which yours sounds like to be one.

Hi I'm new to these forums. I have just recently improved my broadband line using cat 6 cable. This improved my attenuation from 13 db to 7.5 db . However my speed is downstream seems to be stuck at 34354 Kbps with my Attainable rate at 50299 Kbps. Does my DLM have to be reset or does it do its thing automatically, (it is past the 10 day initial period). Another thing I noticed was my RS correctable errors were at 53676 with an up time of 2 days 14 hours. Is that normal?

your line clearly wasnt up to spec before, given your line stats.

you do seem to be on a very odd profile however (8/14ms) but ild say something is miss reading given your 4 INP which would put you on a DLM-8 profile - the worst prettymuch.

in your case, i would have DLM reset. to get down to DLM-1 otherwise it will probably be a few months. DLM does work after the 10 day period, but at a much slower rate.

your on a high profile, so i wouldnt expect your errors to be as high as they are, however for two days up time, your errors are rather minor, and perfectly fine. see how they go after the reset.

dont get too hung up on attainable, they can often be wrong. given your profile, your speed and attenuation, i suspect DLM has poked its fingers in all the holes it can however.

once DLM is reset, dont turn your modem off, dont reboot it. just leave it in its corner to do its thing.

How do I get the DLM reset? Do I just email Orcon to get it reset? I have phoned Orcon , but they aren't that much help with their overseas help desk.

you should simply be able to ask for one. if their CSR (assuming you called technical support) does not understand the request.. ask for someone who does...

Just called Orcon. They told me they do not monitor these connections, and therefore cannot reset DLM. Talk about frustrating!
Is there anyone that works for Orcon on these forums that could possibly help me?

Hi Ian, can you clarify what you mean by "I have just recently improved my broadband line using cat 6 cable" - I presume you mean you changed your internal wiring and fixed an attenuation issue there??

We can request a DLM reset via Chorus Assure but at every step of the way through VDSL Chorus are telling us that DLM should be left to do its thing and any changes may be potentially chargeable so I am keen to understand the rationale before we do so.

with snap, they have two ways they do DLM resets, first being via chorus, and second being a process of rebooting something which kicks off the DLM process all over again.

i figure what he means, is he has fixed an internal wiring fault - which technically would infer also that chorus iver didnt do their job, or didnt do it correctly too...

clearly given there was a huge attenuation change, due to fixing a fault, would qualify a DLM reset, however in my experience rationalizing them isnt that much needed - or the CSRs are great at rationalizing for you.

You are correct there, all Chorus did was install a line splitter, what I did to improve the line attenuation was to remove the old phone wires and install my own dedicated cat 6 cable for broadband. Now I'm stuck with the slower profile and was hoping to fast track these profile changes by resetting my DLM to initial settings.

in which case, it would have been rational to expect chorus to comeback and do that for you too.

none the less, the fact that chorus didnt do things to spec, which pushed you all the way back to DLM-8, and that you had to do it yourself, i dont see why it possibly couldnt be justified.

Well we will request a DLM reset for you BUT the information I have direct from a Chorus whitepaper is that during the validation phase (the initial 10-day training period), the DLM assessment cycle runs at 1min intervals, once the connection enters the Operational phase the DLM assessment is at daily intervals. Now if that were so then in most cases there would be no point to a DLM reset, by the time it was requested and actioned by Chorus it would have re-assessed in any case.

We will see....
