S.N.R.M. INCREASE

I have a very long >6Km E.O. line.

In order to try to provide a reasonable working speed, I was placed on a fixed 6dB S.N.R.M.
with interleaving on.

I could manage the occasional disconnects, no problem.

I now find that I have a 9dB S.N.R.M.which gives me a synch. speed of 1024Kbs.

T.T. inform me that they can no longer change the speed, and that the line profile is done automatically by B.T.

Is there any way of overriding the 9dB profile?

Thanks.

Is this a full LLU Talk Talk line, as in they provide the voice service also ?

If so then the CS staff were telling porkies, only TalkTalk can change the profiles on their kit.

Thanks.

Yep.. Full LLU + voice

Have now posted a request on the TT forum.

Our New Dynamic Line Management system

Re.synched at 04:00 now back on 6dB SNRM.

The response from TT.

"We no longer have the option to manually change profiles as this is now managed by DLM."

I guess this also means TT can no longer switch off the DLM if requested. It seems line management is 100% automated now.

Most nights I suffer from spells of some form of interference/crosstalk/?

I use a 2Wire HG-B router, that can "hang on" to a poor signal.

Unfortunately, it now seems that DLM will increase SNRM, and give me an almost unusable speed.

Are there any plans for FTTC/P in your area? EO lines are being slowly upgraded albeit mainly under the BDUK scheme, with priority being given to cases like yours where EO lines are a long way from the exchange hence poor speeds on adsl1/adsl2+.

No plans at the mo. my M.P. is/was involved. Could be a very long wait.

I'm guessing the CS bod you spoke to originally could do with some 'additional training'

Glad you got it sorted.

Had a "good" 6dB SNRM 1536Kbs until 03:30, router re-synched to 9dB 1024kbs.

This speed is almost useless.

TT performed "a line test" this am, showing a loop fault,

I've ran a test on the line which has detected a potential loop fault which can often be caused by internal wiring or equipment connected to the line.

I have a prefiltered socket, the 'phone is crystal clear, no crackles whistles or pops.

So does TT now operate a DLM as per the link above or not?

Im with Pulse8 but essentially a TT line and i can still get P8 tp manually set my SNR

Direct from TT.

"DLM is still optimising, has set profile to 1.5Mbps at around 3:30am

DLM generally makes profile changes at around 3:30am"

Do you know if that time for DLM changes is specific to your line or in general?

That is all I know, so far.

My queries are ongoing.

I've had a few issues with my ADSL2+, TTB SMPF, 37dB downstream attenuation, connection recently (high error rates) and to remedy the problem I forced ADSL2 with a downstream SNRM of 3dB (previously on 6dB) - downstream throughput has reduced from ~10.3Mbps to ~9.3Mbps but the line is now stable. I have an open ticket with xilo/uno regarding this issue and the guys there recommended that I stick with ADSL2 and didn't advise me to change any router settings (Billion 7800N) for the foreseeable future.

TT DLM, has now forced me on to a download synch. speed of 1024Kbs.

Which is almost useless.
