Why are EURESCOM Partners Why are EURESCOM Partners Collaborating in this Work?Collaborating in this Work?
• Opening of world markets will not see the total decline of correspondent working in the short term
• The granting of more international licenses will require inter-working between many more partners (capacity providers)
• Consistency and automation of process is essential for operational efficiency
• A common understanding and resolution of issues for systems implementation is essential for success
• Results are applicable to all inter-operator connect activities, not just international ‘cross-border’

• P707 is actively downstreaming results into Standards (ETSI TC/TMN)
• Utilising a realistic case study has greatly enhanced project ability to focus upon genuine implementation problems
• Investigation of real implementation problems is expected to prove useful for other technologies Thank you for your attentionThank you for your attention
