BTw to LLU


[link to this post]
 
I recently switched from EE to Sky FTTP and wondered how the physical backhaul change is carried out in the exchange.

How do they switch my line over? I know there are layer 2 switches in the exchanges but how does one single line switch from BTw's core to Sky's?

By moving the customer VLAN from one link to another - which is just a config change.

So there is no physical change at the exchange?

Only ADSL is LLU where the service is changed between each providers hardware.

VDSL2, G.Fast and FTTP all come from OpenReach's hardware. They all connect back to an OLT, with multiple OLT's connected to an L2S.
Each provider buys a GEA cablelink for each L2S in an exchange.

When you change backhaul the data is moved from 1 providers GEA cablelink to the others.
It's all done remotely.

Thanks to you both for confirming. I thought it was still a physical switch.
