3. TMN Workshop Antwerp, 27 May 1998 P PET Lab PAN EUROPEAN TMN LABORATORY TMN X Interface Studies & Experiments for SDH (P707) Why are EURESCOM Partners 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’
