LLU explanation help

Hey

Im trying to find a simple explanation on what is and how does LLU work.

also what differences would there be to standard BT line and BB connection.

With regards to this mac code business am i correct in saying this
" When moving from a DSL provider to another DSL provider you require a MAC code, when moving from an LLU provider to another LLU provider you require a MAC code but when moving from a DSL provider to a LLU provider you do not need a MAC code."

if anyone could explain or at least point me in the right direction i would be great full.

Thanks

LLU = Local Loop Unbundling

It's basically allowing telcos and ISPs to put their own kit in BT exchanges so they're not reliant on BT's backhaul services, meaning they can offer different products, for instance ADSL2.

Just google "local loop unbundling" and you'll get more info. Something like this might be useful too.

You did take a look at the sticky, right?

" When moving from a DSL provider to another DSL provider you require a MAC code, when moving from an LLU provider to another LLU provider you require a MAC code but when moving from a DSL provider to a LLU provider you do not need a MAC code."

If by "DSL provider" you mean an ISP using BT Wholesale ADSL, you need a MAC key to move between them and to move to and from a BTw ADSL ISP and LLU ISP. Migrations between LLU ISPs are a bit grey, but you should only need a MAC key.

Correct as far as saying they aren't reliant on BTs backhaul service, LLU comes in two flavours, both allow kit to be installed in the BT exchange, but the telco can opt to use BES (BTs Backhaul link) or their own network.

The problem you now have though is that BT are running out of space in the exchanges for telcos to put their kit, so instead of pooling their resources, telcos are competing against each other, so the only differentiation will be service. BT must be laughing their socks off, especially as with 21CN it will make the telcos customers again.
