Sorry, SIM?

Service Iterface Module.

*edit*
Just checked the bit loading vs dB on the HLOG.  It seems that (dependent upon frequency) the cut off for getting a "bit" per tone seems to be in the region -65 (higher tone) to -68dB (lower tone).

I would concur with those suggested values.

FWIW, my line is around 1100m (confirmed exact route, physically measured with a trundle wheel & allowing for down one pole and any 'slack' within joint chambers etc.).

I initially thought it was shorter than that, but I am now aware that it doubles back on itself in 2 places, adding approximately 200m to its 'real' length.

The 1100m is also confirmed by a visiting engineer's JDSU readout (see attached).

Sync has dropped another 5Mb today at 9AM this morning, to 31852 Kbps.

The minimum we're supposed to get it 25.7 so we're getting closer and closer to that...

RF3 should be arriving at some point today, I've also got a much higher quality VDSL cable (Cat 6 cable) installed.

That's the kind of drop I had when my neighbour got fibre...

SNRM is reducing less at night, by the looks of it?

[GigabitEthernet]

Don't really know what to do with this now.

Tell TalkTalk that their service is unfit for use?

Migrate to A&A and invite them to enjoy having your service operating correctly?

 

Sorry Alec but it is your decision as to what you now do. But please keep us updated . . . 

[GigabitEthernet]

The issue is, A&A don't support the use of the landline for anytime calls, they're also outrageously expensive.

 I can't see any drop in your attainable in last few days and otherwise things look a but more stable. I remain of the view that a noisy line of your length can look like yours.  The RF3 may help. 

What you do really depends on what you use the line for. For my use I would cap the speed down to about 3Mb/s and hope that with the reduced errors, interleaving would be removed (after up to 3 or 4 weeks) and if it is enabled on your DSLAM you may just get just G.INP which would probably be ideal. If interleaving is removed you could cap the speed at a higher level similar to one that interleaving currently gives in order to keep it stable..  The speed won't be the best but for me fast path always feels better even when just using the web.

   You could also consider a move the Plusnet or ZEN in order to get the fast DLM profile (and different support team).  This would allow twice as many errors per day before interleaving hit.  I am with TTB and cap my speed to ensure fast path.  Without the cap it can be fine for month then one big noise burst will cause interleaving.

I did try the RF3 but I couldn't get the HG612 to sync with it

Can you just confirm the correct way to wire it?

As a result of a fellow Kitizen's trouble in wiring a BT80B-RF3, a brief guide was written and Eric deemed it should have "sticky status". 

[GigabitEthernet]

May I ask, does the incoming wire go into the screw terminals or the IDC terminals?

[les-70]

  I think they are usually wired -screw in- for the  drop wire side and -IDC- out to house/modem.  I don't think it actually maters which way round it is used.  I think the choke response should be symmetric.   If you ease the pcb out of the case the devices circuit is fairly clear.

Connection has now been up for ten days so at least it's stable.

SNRM seems to be dropping less than previously but I cannot help but feel disappointed in the performance
