I have had very consistent high sync (80) but low throughput (50/60) for a while and a number of engineers visits.
OR engineers when occasionally using their own laptops confirm low throughput speeds.
My ISP shows me KDB test results and some of the data does not appear to be in real time.
Sync's appears to be real time.
Profile name does not.
0.128M-74M Downstream, Retransmission Low - 0.128M-20M Upstream, Error Protection Off
* this appears to indicate retrans only on the downstream *
It says my cable is 162 Mtrs and recently my line is now banded ( Rate Capped Profile ? ) at 74, down from 80.
There is a Time Stamp and it can be up to a max of 13 days behind the date of them running the test.
I wonder if any other field in the KDB database are also 13 days behind that and be relevant ?
The other thing I have noticed, every time an OR engineer has visited me and run tests with the hand held device the KDB date gets set to that date and time and remains so for the 13 days.
Does that indicate the DLM has been reset ?
ISP reports occasional copper faults but never seen by OR engineers on site.
"Description Impairment in copper joint detected most likely in local network. Please continue to submit a trouble report
Main Fault Location CE"
" Current RRT Brag stability index is good, some upstream forward error correction evident,
nothing on the downstream, it is very variable however, only 8 yesterday, 128 on Friday."
* this says retrans only on the upstream *
Standard speed test sites often report high latency, generally on the down ( have seen 5000 ) but recently on the up.( 500 )
The router reports max rates of 88709/27493.
