Mrgg:  Downstream line attenuation (dB): 35.7  

 

There's the issue right there. Closer to 4 or  5km, assuming there is no physical line problems.

 

@hio77 around, or having a break?

 

 

Probably asleep.....

Mrgg:

 

sbiddle:

 

At 2km you're too far for VDSL2 but ADSL2+ should be fine.

 

You need to elimimate your internal wiring as the cause of the issue because statistically speaking it's the most likely cause. You own this wiring, not Chorus, so you either need to pay somebody to fix this or pay Chorus to install a master filter to eliminate the internal wiring.

 

How many jackpoints do you have?

 

 

 

 

It's a dedicated jack for the net

 

 

You say you use filters, that doesn't mean its dedicated (And therefore taking out any other writing issues) A master filter makes it dedicated, using filters "hopes" to filter out other wiring issues

 

2km is too far. I recall 900m was max, over that and its falling. Do you have voice? Bit back in the day now, but voice is only 4kHz separation from upstream, again internal wiring

hi,

 

when we moved in the tech that hooked everything up said its the sole jack for net (none of the other jacks work for net) so i assume its a dedicated jack/splitter

Relevant feedback from another post around here; (paraphased)

 

 

 

Had another customer, also with slow upload, attenuation seeming on the high.

 

Fault in an essence bottled down to badly done wiring, where an alarm was installed with essentially a bridgetap which was also exposed to a uncapped 3phase lead (likely was never meant to be connected)

 

 

 

His connection went from 12/0.4 straight up to 29/10 which is right within expectations for the line. (for context was a rural line, as the crow flys about 1km in road, physically measured in the field by a tech to be 1.4km to the dslam)

 

Distance issues with VDSL are far less of an issue with 998 over 997 where the 900M was max. The catch is, VDSL is FAR more susceptible to faults that can be easily 'rectified' by downgrading.

 

 

 

Not exactly obvious, and often something that sadly a field tech may miss..

so looks like a possible bridgetap on US0. Surprising this affected ADSL more than VDSL.

 

Sadly records were not taken that are detailed enough for me to dig real deep into the ADSL rates.

 

 

 

Dedicated jackpoint, sounds very much like an ADSL2+ Rated splitter installed, possibly gone dodgy as it is having symptoms typical of this.

 

I've asked OP to take a photo of inside ETP if possible.

 

 

 

Based on both surrounding physical lines, line tests and the physical crackle on the landline it certainly does add up to something being not quite right.

 

Will be working further through with the OP :)

Chorus came out after much argument that the line was perfectly fine. (i tugged on the voice issues before assure would ever agree)

 

 

 

a HR loop B-E was resolved in the ETP, line has now gone to a very nice looking ADSL2+ Spectrum. VDSL and above is still in question.

 

Case was REP2CPE, this wasn't done but the attenuation is back down within spec so there may be very little i can do further to this. (still testing further)
