1. 60000 down 19455 up
2. 74312 down 19455 up
3. 5 months capped
4. Testing Netgear router ( Beta testing unit bad firware causing sync drops )
5. Current SNR is 18.7dB
Line was capped at 35 but after a fight with EE then raised a task to BTW and line now capped at 60
My understanding of the DLM system -
DLM uses a system called ‘Caution Counters’, this dictates, based on the quality and performance of your line what band/profile your line should be on as well as how long it will take before your line needs to be stable (Green quality) before increasing the speeds.
The counter then starts to count up to 9, the line remained green; the top profile would have been re-applied. In this case, the line started to error again, DLM reduced the profile again to try and control these errors.
You can see that there is a ‘barrier’ which shows at 0, 8, and 24. If your line had a bad day, you’d be put on barrier: 8, your line will then have to wait for 9 days (barrier=8 +1) before any positive profiles changes would be made. If your line continues to error/perform poorly, the barrier is increased, following the same rule as before.It’s important to bear in mind that it’s very unlikely that your profile will be set at its lowest without there being some kind of fault with the service, which an engineer would likely have visited and repaired and performed a DLM Reset.
At this point Openreach are also testing new 3dB SNR's in my area and so i am waiting for 25 days of sync before i reboot the modem.
