- The speed your Openreach modem connects to the Fibre cabinet. - The line profile set on the RDSLAM which is the system in the cabinet that your modem connects with. - The speed profile on the BT network sometimes referred to as the IP profile or the bRAS profile. - The speed profile configured on our network layer sometimes referred to as the Plusnet profile.
In relation to the above quote would be grateful if a PN member of staff could tell me which of the above has reduce my speed by 10 meg.
I was the first connected to my cabinet on 1 march this year. Engineer confirmed line to exchange could handle 85 meg. Until last week or so getting 75 meg and Bt ip profile was 77 meg. Last couple of weeks open reach have been working on the cabinets and my bt ip profile now 67 meg. Can't see it being the pn profile as last time I looked was 20.
Thanks in anticipation

To be perfectly honest with you we may never be able to tell you precisely which of those factors is actually affecting the speed as there's no hard and fast way to prove or disprove those factors I'm afraid
Quote The speed profile on the BT network sometimes referred to as the IP profile or the bRAS profile. - The speed profile configured on our network layer sometimes referred to as the Plusnet profile.
They are actually 2 separate things, BT's BRAS or IP profile is one level, secondary to that we have our own speed profile which should match that.
As you may know the DLM process for FTTx is entirely automated and may reduce speeds if there are perhaps other factors affecting your connection although it is realistic that an increased uptake of fibre products on your cabinet may lead to a slight reduction in speeds.

Are you at least able to ascertain the setting of my cabinet - ie has that changed from 77 to 67?
Thanks

Do you know how far you are from the cabinet? It seems fairly common for DLM to knock up to 10Mbps off the sync speed if it detects certain errors, you may find it goes back up again. This has happened to me a couple of times, I'm currently in a "down" phase (the downs tends to last longer than the ups, unfortunately!)

Kevin can you indicate which "certain" errors you refer, and possibly which xdslcmd info command you would use to log these?
Thanks

These commands will provide most of the relevant information:-
xdslcmd info --pbParams
xdslcmd info --show
xdslcmd info --stats
The Windows Graphing Scripts obtain the above information & also obtain & plot this additional information (thousands of rows):-
xdslcmd info --Bits
xdslcmd info --linediag
It should be noted that the GUI's reported error types are a bit mixed up.
Information obtained via xdslcmd appears to be far more trustworthy.

Thanks for the help. I don't suppose you know if the scripting tool is available for Mac? (virtualising Windows can be problematic).
As an aside do you know of any other similar tools that are compatible with the standard OR modem (Idle curiosity that's all).
Thanks

Sorry Mark. I have no idea.
I wrote the Windows scripts, initially based upon the original Linux script (graph.sh) which is available at the same download site as the Windows scripts.
Someone, somewhere, may have possibly converted my scripts for native Mac use, but I am not aware of it.
I believe Linux users are able to run the Windows scripts in a Windows VM with no issues.

I am not aware of any other similar tools.
However, some other VDSL modems have built in graphing tools. e.g. one of the FritzBox! modems (can't recall which one now, but it is discussed in the thinkbroadband forum)
EDIT:
The FritzBox! 7390 is the modem in question.

Example attached.
At any given moment in the universe many things happen. Coincidence is a matter of how close these events are in space, time and relationship.

Thank you for your previous reply, very much appreciated. I must say I was very impressed by the output from the scripting tool you produced and have had a go at trying it out. I have a quick question. My (WHS) home server is located at 192.168.1.1 and this would be a major pain to move, so I've been running the OR modem web interface at 192.168.1.250 instead. I know your scripts expect the modem to be at the default IP address and I did spot one instance in your files, where I edited the IP address to reflect my modem location, but it did not work.
I don't suppose you could give any clues to any necessary modifications to make your scripting tool work at my modem IP address.
Alternatively I'll have to turn my server off for a while, prove I can get this running on the Mac as a Windows VM and then decide what to do next.
My ultimate goal was to get this running permanently on the Windows Home Server once proven and tested.
Thanks once again for all your help.
Mark
