Hello

When an ISP refers to being LLU, what does this mean? As something is happening at our exchange and it points to this...

I also had someone pop by the house asking if we was aware of this and wondered if I was on the isp she was referring to...Which I am?

Basically, non LLU uses BT datastream networks which has various downfalls, LLU allows providers to use their own networks from end to end.

Ahhh okay, I did have a little look, I just didn't know if it made any difference for the user at all? Potentially fast speeds if the line allows it? And the equipment obviously
 
All depends on how congested the areas are and how much bandwidth is wired up. Large catchments on 1-2 llu providers can be horrible to be on in some areas.

If they are installing LLU hardware you can probably expect better performance at a later point or more speed/packaged options trusting everyone doesn't jump on it all at once.
 
To keep it simple, LLU is short for Local Loop Unbundling. This allows ISPs to install their own kit in BT exchanges.

Without LLU kit being present in the exchange, all ADSL connections are provided over BT's network. LLU allows BT's network to be bypassed (except for the physical line from your house to the exchange).

In reality you'll find LLU ISPs offer larger caps or potentially even no caps at all. This is because, with BT's network being bypassed, they are not subject to having to pay BT for bandwidth charges. Since it's still ADSL however, and BT offer ADSL2+ now, sync speeds are unlikely to be any different.

Sorry mate in my case the sync speed was different and as I mentioned remained so as there was no profiling :)

Higher sync depends on how long/noisy your line is. Long/noisy lines say above 50 to 60db aren't worth having LLU as the line would not cope.

I'm guessing your line length/noise margins was good hence the better results with LLU.
 
it's not so clear cut that BT will offer ADSL2 in your area, in my area the exchange is only serving around 1000 premises and BT currently has NO plans to upgrade it to ADSL2 so when LLU came around I jumped at the chance. Biggest difference to me when we moved to Sky is the 3x upload speed increase...
Sync has stayed roughly the same, but actual downloads have increased by just over 20% too. What ISP were you looking at?
 
If it's your current ISP that's upgrading then chances are you won't get a choice. It's cheaper for them if you're on LLU so you'll probably get moved whether you like it or not.

Quite the oppsite its a miracle I can even get a connection Im that far from the main box. My connection on adsl was around 750kb but when I moved to LLU I had a steady 1.5mb plus even went as high as 2mb with a bit of SNR tweaking.
 
cheap and cheerful isp then...I guess you'd be looking at alright service with slowdowns at busy periods if my experience is anything to go by...

Well yes, they were the cheapest, paying £20 a month for broadband and calls and line rental, so hey.

Occasionally the router drops out, but a reset sorts that
 
if you're with sky it's about the same price if you have a tv package and appears a better service. you get what you pay for though and as long as you're happy
