What DLM profile do BT use?

Go to solution

Hi,

 

Anyone knows what DLM profile BT uses? Stable, Standard or Speed?

 

I am wondering, because I have been interleaved recently and now getting very low ES rate (5-6 per 24hours) and don't seem to get fast path back with total uptime of about a week now since connected HG612 to monitor my stats.

 

Thanks

Nope, think you will find it is 'Speed'

Are you sure BT uses stable profile?

 

If so, the maximum allowed errors are 30/hour and 1440 per 24 hours. This can't be right as I used to get over 40 ES/h on fastpath and been like that for more than a year.

Thanks for reply guys.

 

How many drops does speed profile allow and what is the ES threshold?

I'm sure you've been through all this over on Kitz. But here's the figures.

Thanks,

 

Yes I've been through this on kitz but no one ever clearly said what DLM profile BT use.

 

First time seeing this table, thanks for that!

@Webby

 

Thanks for confirming.

 

On the other hand what could have caused the maximum supported speed by my line to drop quite a bit? It used to be around 52-42Mb (Range A Clean) down and 11-8 Mb up. Range B has dropped as well. Although my HG612 OR modem still showing same attainable speed with same SnR for both DS and US. I know when interleaved attainable is higher than it should be but still. Possibly crosstalk?
