  1. INTERCONNECT WORKING GROUP28 JANUARY 2005Update on Legacy Interconnect Migration Proposal ANTHONY SHEPPARDSENIOR PORTFOLIO STRATEGY MANAGER The information in this presentation relates to plans currently under development and subject to consultation, and may be subject to change. Detailed implementation depends upon a number of factors including the capabilities of suppliers and the final 21CN network design.

  2. Feedback from 17 December Initial Proposal • Objections to BT Forcing Large Scale Migration to Aggressive Timelines • Lack of Clarity about Tandem Re-Arrangement, Focus was on DLEs • Concern about Commercial Uncertainty of Conveyance • 6 months Proposal on Backhaul Seen as Inadequate • Confusion about Treatment of Dial-IP

  3. Revised Proposal on Timelines and Scope of Migration • First system alteration notices postponed from Feb 05 to Jul 05 • Pathfinder Working Group to meet on 11 February • Tandems will remain in place until 2009-2010 • Mitigates need to re-arrange the majority of interconnect • Allows time for fit for purpose NGN Interconnect as discussed this morning • Provides a safety net for our current mutual dependency on IUP • Altnets interconnected with fibre to only ~82 DLE sites closing in 2006-10 • Minimises geographic migration to 2,449 E1s of ISI interconnect for 7 Altnets • DLE interconnect circuits at Tandem sites, repointed from DLEs to Tandems

  4. Context of Conveyance in 21CN • EBC regime continues as long as the legacy network exists • DLEs and Tandems will continue to exist through 2010 • Prices set within the Network Charge Control review • NGN interconnection and conveyance to be determined • Based on new interconnect products • Informed by Next Generation Interconnect WG, NICC and Ofcom • The transition period requires: • The NCC to set prices for legacy interconnect services • On a consistent basis with the agreed migration plans

  5. Revised Proposal on Legacy Interconnect Conveyance • Interconnect Circuits to Tandems Unchanged • No impact until 2009-2010 • Network Charge Control remains in force • IEC interconnect circuits to DLEs virtualised • Altnet continues to pay IEC charge (virtual) • Altnet continues to pay DLE conveyance rate (virtual) • For DLEs co-located with Tandems, an IBL is provided • ISI interconnect circuits to non-Tandem DLE sites • Represents only 2,449 E1s from 7 Altnets at ~82 sites • FRIACO a subset of these circuits • BT will negotiate with those impacted to determine an equitable solution
