Thanks for your reply.
BTW / BT Wholesale are a customer of Openreach that buy Openreach products and deliver them in a more convenient way. They also provide some broadband services of their own, partially renting copper from Openreach and adding the broadband via their own equipment.
So over here:
https://kitz.co.uk/adsl/BT.htm - it says: "BT.com and BT Broadband are customers of BT Wholesale."
Does that mean, if I'm a retail customer of BT, essentially I go through BT.com retail, who buy from BTW, who buy from Openreach?? If so, why wouldn't BT.com just go directly to Openreach, and skip BTW.
WLR is an Openreach product. It is the voice part of a service where CPs / operators don't want to handle it themselves.
And, what if the CP doesn't want to handle both the broadband and the voice? What product would that be called please?
Were you maybe thinking of LLU and BTW? In the age of FTTC/P there's a lot less difference between those than there used to be.
I'm mainly focusing on the copper not Fibre for now. I do have some questions about LLU as well. From my understanding it's where Openreach allow other CPs to rent the copper line so they can sell it to customers, but not too sure about much beyond that.
