accidentially powered down router in first 10 days of llu

[NoobieOCer]

i recently change isp to sky and was connected for 6 days now. but i accidentally unplugged the power when i found my phone power was lose. now do i have to call sky and have the training thing start again?

When you reconnect the router back, it should sync at the same speed as it was connected to before or if not near enough or maybe better. As you are still in the 10-day training period you should be ok. After the training period is over you can always call Sky to ask to re-enter the training period for another 10 days but I wouldn't worry about what has happened as loss of sync is to be expected at some point during the first 10 days, even if you accidentally disconnected the router.

Does training apply to LLU? I didn't think it did.

I too am intrigued by this question. Whilst not using Sky personally I came home the other day to find my connection speed had increased from just under 8mb to 17mb in the router.

I can only assume that tiscali have moved my line to their own equipment within the exchange. Unfortunately after turning a lamp on it popped and blew the trip to my sockets. Upon reconnection it only synced up at 16meg odd instead of the 17.

There is a difference between a shutdown and a loss of sync.

If you shutdown the router then a dying gasp is sent and the DLM does nothing. If the line drops sync (usually due to low SNR) then this is recorded in the DLM and the DLM decides based on a set of rules if the sync speed is too high and drops it, raises it or keeps it the same.

During the training part of the profile, RAMBO records the line stats every (from memory) 15 minutes and uses this to determine the Maxiumum Stable Rate, which in turn sets the Fault Threshold level (which is 70% of the MSR).

What does that all mean..... not a lot really.

The fault threshold level maximum sync speed you'd need to have before a fault is assumed ie.... your Maximum Stable rate was determined to be 10Mb, so if it syncs under 7Mb it's assumed to be faulty.

If it is using a 10 day training period - I don't think most LLU connections do - it will be using blip logic so that a one off sync event won't affect the training.

Depends I would say, if you are pulling the plug, then your going to drop sync

I dont think it matter anyway, most of the line training is done within the first 5-7 days usually, wont make any difference

even if u pull the plug a dying gasp should always be sent. There would be a couple of capacitors with enough power to send a gasp in that situation as it very very short.
