Addressing the local call disadvantage

Ofcom considered that it should require BT to implement a CPS local calls option for DLE-interconnected CPSOs. However, Ofcom also accepted the view of the majority of respondents on how the policy solution to the local call disadvantage should be implemented. That is, Ofcom considers that BT should offer two network routing options to CPSOs within the 'all calls' CPS subscriber option, rather than implement two new CPS subscriber options as initially proposed by Ofcom. These two routing options should be:

• the current routing arrangement, i.e. all CPS traffic handed over to the CPSO at the point of connection; and
• a new routing option that routes a subset of calls end-to-end on BT's network and continues to route all other calls according to the CPSO's routing plan. The subset of calls to be routed end-to-end on BTís network are those that are originated and terminated on the same DLE or originated on one DLE and terminated on an adjacent directly-connected DLE. These will henceforth be referred to as SAD (Same/Adjacent-DLE) calls.
