• To address competition concerns in market for terminating segments by encouraging take up of PPCs
• PPC Phase 1 - set out our market analysis - target competition concerns.
• Phase 2 - Applying proportionate regulation to remove obstacles which prohibit OLOs taking up PPCs -e.g. Costs reductions & effective SLAs
• PPCs enable OLOs to compete with BT at Retail level
PPCs - Oftel’s aims
