Infinity One Exchange Problems?

My Infinity One connection has methodically declined from 50Mbps line and download rates to just 34Mbps download rate with a 40Mbps line rate.   After a long period of self-recrimination, I have decided that the exchange's procedures are responsible for the methodical decline.

My 50Mbps line rate moved first into a 44Mbps profile band, then into a 40Mbps profile band with correspondingly lower download rates.   Then, recently I noticed that although the hub was not interrupted, the network was being interrupted at about 6am in the morning.    This could only be an exchange issue, procedural or otherwise.    Up to that point I had automatically blamed the possibiliy of power down events without really checking the stats times.

In fact, I now suspect that the Infinity One service that I get is in fact a 70Mbps Infinity Two service that was simply  capped in the 54Mbps profile band.   By starting out in such a profile band, the service would not be Fully Rate Adaptive at all and would be sentenced to, at best, automatic decline subject to the need for manual intervention to correct the matter.

What is done at 6am in an exchange - shift change?  Is Infinity One just an impaired Infinity Two that always starts in a fixed profile band?   Is manual intervention required always to shift bands upward.  Why is it that despite the availability of power-down advice, BT still reads them as a line interruption?   Or, is hub power-down being blamed for something else - a faulty link management system or the ubiquitous "problems at the other end".

Just so that you are aware, Infinity 1 and 2 are exactly the same product and all that happens if you purchase Infinity 1 is that there is a software cap that should your line be capable of exceeding the top speed of Infinity 1 it is not able to do so.

If you were unable to get the maximum speed for Infinity 1, as in your case only getting a maximum of 50Mbps,  the cap would not affect your line.

If  however there is a fault on your line the automated DLM (Dynamic Line Management) system will act on your line and lower the speeds in order to maintain a stable connection.

In order to try and diagnose what your problem may be can you run this checker and post back a screen shot of the results. Make sure you delete your phone number before posting.

http://www.dslchecker.bt.com/adsl/adslchecker.welcome

and use this speed tester then scroll down the page and carry out the further diagnostics and post back a screen shot of all the results including your IP profile for up and down. This test must be done with a wired connection.

If you have a Homehub 5 can you post the stats from 1-12 by logging onto the Homehub management pages then troubleshooting > helpdesk. http://bthomehub.home/

or

If you have the Smart Hub, (Homehub 6) can you go to hub manager then advanced then technical log and post the stats. http://bthomehub.home/

Is there any noise on your phone line? Dial 17070 and select option 2, there should be no noise between the announcements.

Try connecting to the master socket/ test socket and if your problem is still there it could indicate that there is a line fault before the test socket on BT's side.

When you use the test socket make sure that any telephone extensions you have are "dead". There should be no dial tone at any of your phone extensions. If they have a dial tone it means you have star wiring and that is not good for Infinity and will need to be fixed.

Re: Infinity One Exchange Problems?

If a MODERATOR wants information of this type from me, I would supply it, but frankly the matter could be solved by just resetting the line profile to the proper value.   However, every time the exchange interrupts the network at 6am the system detects it as a line problem, and reduces the  profile band, so I expect that despite any reset, the matter might well happen again until either the offending proceedure is identified or the line management system learns its business better!

Re: Infinity One Exchange Problems?

The moderators only become involved once all other avenues have been explored and they can not reset DLM on Infinity. It can only be done by an engineer after a fault has been fixed.

In any event it would be pointless doing a reset without fixing the underlying cause as all that would happen is DLM would "kick in" again and lower the speeds again.

As you apparently to not want to supply the information asked for I will now bow out of your thread.

Frankly, the matter would not be resolved by resetting the line profile.
