Re-sync problems

After dozens of syncro losses over 10 days, and connection at 160kbps - BT repaired the line? after 4 visits.

Great! connection speed 4096, 41db attenuation, 10db snr (4.54mb available in my location)

TEST SOCKET connection all through.

44 hours on, and still with a speed-test result of 160kbps, (but patiently awaiting the big 0-5 days re-set in heaven) - Disaster struck � loss of syncro for about 40 mins.

Connection speed now 3872, with 41db attenuation 12db snr.

Is this all part of �re-profiling�, or do I now have to await a further 0-5 days � which like Manyana, never seems to come?

When I�m not on-line, would it make any difference in switching the router off?

I should add, that whilst it shouldn�t make any difference, I�m in the �dead-dog� days of leaving MAAF and converting to Sky, and have just received the SKY connection code.

Have MAAF consigned me to the final departure lounge, where the service is hit and miss near the edge of the world, as I keep reading about mishaps due to their logistics at present etc?

Any help appreciated

If you are moving to Sky LLU you will not be plagued by BT profile delays once you have moved to Sky's kit.

Depends what caused the loss of sync, and is the 3872 the first sync after your 4096. Is it possible it re-sync'ed slower than 3872 before losing it altogether?

If it didn't go slower than 3872 then probably no harm done to the profile rise except you will only get 3Mb not the 3.5Mb you were heading for. I'm surprised it hasn't already happened though.

You may have lost the 10-day stability for getting the 12dB to drop. Possibly you will be ok on that as well though, nobody really seems to know.

"Converting to Sky". Sky LLU I hope? If it's Sky Connect you may as well just go jump off Beachy Head.

MAAF cannot cause a loss of sync.

John, thanks for your reply,

My exchange, (2.27 kms distant) is LLU enabled, so presumably SKY will utilise that facility.

I was delaying the migration hoping that with new BT cabling I would ge a high re-sync to depart with. From what I'm reading I may as well get on with it then?

Yes, you might as well get on with the move, none of the parameters such as current sync rates, IP profile, MSR, FTR, etc. are relevant to a LLU connection (although the sync rates will give a guide to expected performance).

Afternoon Roberto,

I can't tell if I went below 3872, the Netgear DG834G log only shows;

I should add that the 'Loss of synchro 13, (above) was the first for 44 hours after BT supposedly connected to a different pair from my home to the local junction box. The engineers gave me his mobile number and said if problems persisted, he would appreciate me calling him direct (rather than start a new fault report), he would then connect me to the exchange from the junction box with a newly routed connection.

Since I first posted, a further 2 losses have occurred, and connection rate is now 3968k / 41db/12db. My last BT profile, about 2 weeks ago showed a profile connection during the test of 3000kb. Since then the site kicks me out as not recognising my log-in name, except if I revert to a BT Voyager 210, when magically it seems to identify me!

My local exchange is LLU enabled - thankfully, and as a Sky customer it's free, rather than �18 a month with MAAF (reduced to �9.99, upon notice in all fairness). I figured with such poor performance, it was better to have it free, rather than pay for it?

I have a pal with Sky (10 months) - he's only 600 yards from the exchange and gets 6.7mb. on a speed-test.

However, am I right in thinking that as Sky's free package is limited to 2mb download, that's all he's getting? I've heard Sky limit the download by their router software?

Martin

Thanks John,

The exchange also has Sky/easynet enabled (june last year). Think I might as well get on with it then.

Martin

I think not.

I think you need to get the line sorted out between the junction box and the exchange first if you have just had 3 disconnections. My reasoning being that you are in touch with the engineer, and once you are with Sky if the problems continue then you have to start afresh and hope Sky handle it right.

However, having said that, there are two other points to consider.

First, it could just be the connection at the exchange or the DSLAM/line card doing a funny. Going to Sky would automatically fix that. But you would think the engineer had already thought of that.

Second, if he changes your pair from the junction box to the exchange, you have no idea what quality or length of line you are going to get . Maybe better, maybe worse, though of course probably not faulty.

So, having opened with "I think not", it isn't that simple. What it comes down to is that you need to have a good think about the best way to handle it. Only you can decide.

Roberto thanks for the reply,

The engineer is not aware I'm moving to Sky and was an Openreach 'lineman' not a broadband engineer. My wife gets fed up with the dreadful audible noise on the line, that enigmatically occurs, and keeps reporting this failing. The BB sync faults occur in parallel with this problem.

The 1st BT chap however, did check all our internal wiring, which is newish and has the latest 2 wire only connection (no bellwire). It got a clean Bill of Health.

I have to say there has been no line noise audible since his last efforts.

Interestingly Sky have today advised that BT have told them my line will be be ready to switch to them next week. Maybe BT are carrying out work on the exchange end on the BB side in this connection, which could have caused loss of syncro?

Martin

I don't know, but I doubt it.

I was thinking about my last post - one bit was rubbish - even in my opinion .

If the line pair does need replacing then there is no choice, you just have to take what comes. You cannot live with several disconnections a day.

We are into the realms of how did the conversation with the engineer go, and how sure was he there wouldn't be any more trouble. To me, the mere fact he said to ring him if there was and he would do some more work implies he isn't sure at all. He probably ran out of the time the bean-counters allowed him.
