Code of Practice

Carrier Pre-Selection

Carrier Pre-Selection (CPS) is a mechanism that allows end-users to select, in advance, alternative Communications Providers to carry their calls without having to dial a prefix or install any special equipment at their premises. The end-user subscribes to the services of one or more CPS operators (CPSO: Systemcare UK Ltd) and chooses the type of calls (e.g. all national calls) to be carried by them. The end-user may have a direct retail relationship with the CPSO, or may purchase the service via a CPS Reseller (Systemcare UK Ltd). The end-user is billed for these calls by the CPSO or CPS Reseller.

Wholesale Line Rental

Wholesale line rental (WLR) is a product that BT is obliged to provide to other Communications Providers (Systemcare UK Ltd). It enables other Communications Providers to offer both line rental and calls to end-users over BT's local network. This usually means that the end-user no longer has a contractual relationship with BT and is billed solely by the WLR Provider (Systemcare UK Ltd).
