I assume this is my PCP to the left of it, although it looks a little more heavy duty than some I've seen?

That is a very standard Primary Cross-connection Point, with a pressed-steel shell.

Thanks for confirming, bawss! :D

chuffer, how is your latency so high btw? What does your UK RTT look like?
Latency is a factor in TCP throughput, I believe?

TCP-Window-Size-in-bits / latency-in-seconds = bits-per-second-throughput

Have you had a squint at the wireshark output when you're running a speedtest? Does MSS look normal? TCP retx?

I'm sure you've checked all this so was more for anyone else who might search on your thread in future.

one thing that does spring to mind is... are the air vents greatly reduced on this AIO unit?
If so and these cabs overheat, is the processing speed of the chipset reduced to compensate? Could this explain the reduction in throughput you're seeing?

The vent is the exact same size as that of the smaller Huawei cabinets that also house the MA5616

There are 10,000's of these working across the network.

Might it be possible the 55Mb policer is applied to his line? Can Openreach test the throughput to the cab / cpe, j0hn?


As an aside, this is from the FTTP SIN:

Quote
802.1p = 0 marked traffic will have access to half of PBS & CBS.
802.1p = 1,2,3 or 4 marked traffic will have access to the full PBS & CBS.

A reduced burst-size can affect throughput on some kit.

Does this have any relevance for FTTC? People love to donkey around with the 802.1p bits on the HG612 :D

Have you been on my cat-nip or the falling-over juice?  :angel:

Still have low throughput with high sync problems.

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 read retrans only on the downstream *

It says my cable is 162 Mtrs and 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.

ISP reports occasional copper faults but never seen by OR engineers on site.

" Current RRT Brag stability index is good last 3 days, very good the 3 days before that. 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

The profile name section is exactly 13 days out of date on all GEA tests with any ISP.

We've known about this for a while.

The ISP can get a more up to date profile running the RRT(Reactive Repair Tool) that you mention.

jOhn.

Are you able to add anything to your last post re any other field in the KDB database being 13 days behind ?

The other thing I have noticed, every time an OR engineer has visited me and run tests the KDB date gets set to that date and time and remains so for the 13 days.
