This is where we transfer/take ownership of a number from a “direct” (LLU) provider, so for instance, Virgin where they have used their own infrastructure. With these we have to physically install a new line and “port” the number across to BT.
Wholesale Line Rental. This is where a customer is with another provider other than BT retail, but where the provider is not a direct carrier. On a WLR transfer, we can actually use the existing line at the customers premises, so no new install is required. In essence we just take ownership of the line.
