Getting up to speed

For the first ten days or so, your broadband might slow down or even stop now
and again. That�s normal. It takes that long for your broadband to reach its top speed.
You can help it along by leaving your Home Hub on all the time, and using your
broadband as much as you can for the first ten days. If you�ve got questions about
the speed of your broadband after that, go to

There are far too many stroppy people on these forums who say something isn't true because what they find about the subject doesn't agree with the reality.

Thanks for pointing out that BT Consumer also have it somewhere despite the advertising blurb page that particular poster found. Similar to what I had with another wrt the Zen site. They need to be pointed to the relevant page, as they will seize every opportunity to stop looking for it.

They seem unable to comprehend the BT Wholesale statement

For all ADSL and WBC Fibre to the Cabinet (FTTC) services, the stable line rate will be determined during the first 10 days of service usage.

This 10 days is frequently spoken of by posters on many forums as being told to them by help ISP desks when they have a speed problem.

I wonder in how many facets of life they end up crying "Foul!" when they find they have bought something that doesn't do what they thought it would and they have no comeback. Maybe that colours their attitude - they get the habit of getting wrongly irate at people.

Note that the "first three days" is also largely bunkum. Wrt FTTC it certainly isn't part of the product specification. Go and read the relevant part of SIN 498 by Openreach.

Also note that if someone on a BT Consumer broadband connection finds speeds well below the expected, they will be told they have to wait ten days before the speed can be investigated. That stems from the (incorrect) training the support staff are given.

Even on ADSLx the ten days is not a period during which the speed is likely to rise after the first two or three syncs. All the ten days does is set the MSR, and from that the FTR. So a single low-speed sync screws the user up for all time should a fault arise much later.

None of this of course has anything whatsoever to do with Plusnet product changes. It stems entirely from an invalid statement who got it completely wrong, and now you try to say he was right.

It would be nice to return to the topic. Start a new thread in General Broadband Chatter if you wish to witter on about the ten days on any ISPs.

In reference to support.zen.co.uk/kb/Knowledgebase/Fibre-Optic-Broadband-FTTC-What-...:

Fibre Optic Broadband - FTTC: What is DLM and how does it work?

This guide provides an overview of how the Fibre Optic Broadband (FTTC) DLM system works.

NOTE: The Broadband (ADSL and ADSL2+) DLM system works in a different manner. See our guide to the Broadband ADSL DLM system for details.
What is DLM?
DLM, or �Dynamic Line Management�, is the BT Openreach system used to control the speed and stability of Fibre Optic Broadband (FTTC) connections. Fibre Optic Broadband (FTTC) services from Zen will prioritise speed over stability within thresholds defined by the DLM system.

When a service is first provisioned the DLM system will not act for 48 hours. After this time it is likely to be at its most active as it finds the best balance between performance and stability for your line; this should typically result in speeds similar to the estimate provided to you when you ordered the Fibre Optic Broadband service.
What are the DLM thresholds?
Zen Internet provides our Fibre Optic Broadband (FTTC) services on the �Speed� option. A connection should drop no more than 20 times in a 24 hour period, and should error no more than 2 times per minute.
What happens if a threshold is breached?
The DLM system will take action to bring the line back within the threshold. To do this it may apply error correction, it could slow the speed of the line or both � depending on how bad the threshold breach is. If error correction is applied the latency of a line will increase.

They may not say about a 10 day period, but they do say that FTTC DLM is different to adsl , and go on about how it works, But i don't see and reference to FTR rates on that web page i linked to

http://forums.thinkbroadband.com/plusnet/t/4414676-3...

I see this as something other than the 10 day bunkem that implies that DLM needs 10 days in which to set the highest sync rate possible for a line, it's that mis information about how DLM really work i was trying to point out, no were do plusnet explain that at point of sale but they do link to this 10 day nonsense

You are losing the plot more and more Bob, you only see what you want to see.

That page I linked is THE current BT help page on the matter, the one and only. Same for the Hub 5 Infinity guide. They say 3 days or "about 3 days", end of the matter, and this is essentially true for when DLM will have probably finished its work.

The guide the cheeky troll fed to you is an archived guide from 2010 for a HomeHub 2 hosted on a 3rd party site, out of date and irrelevant!

You're the one who in your thread put in bold that BTw ISPs MUST officially say 10 days... I merely responded, proving that is rubbish, no need to throw your toys out the pram and start a new thread. BT Consumer don't have to say 10 days in their official information, so your excuse for Plusnet needs to go in the bin I'm afraid, doesn't it.

Can you explain why 3 days is now suddenly special?

'step backwards' - expresses my view on it too.

I would have been recommending PN as an option (having changed the 'up to38 Mbps' fibre product to unlimited data - I wouldn't get much better than 33 Mbps according to the estimation tool, but do intend to use Microsoft's 1 TB storage that comes with Office 365), but big difference between uploading at 2 Mbps - my Three mobile with unlimited data + tethering (at 15 quid a month) can go faster on 4G - and some other FTTC offerings...

Also there's Google's unlimited storage with their Photos app for all platforms, so any families taking video clips of children's parties, toddler's first steps, etc, etc would benefit from faster upload speeds... Dumb idea to limit the product, I think.

Sadly looks like my fibre will be from elsewhere!
