In view of the NGN networks are widely spread and In view of the NGN networks are widely spread and internationally recognized, an essential attention when internationally recognized, an essential attention when constructing such networks should be given to network constructing such networks should be given to network functioning quality dependent on many factors, such as: functioning quality dependent on many factors, such as: applying an equipment of the different manufacturers, applying an equipment of the different manufacturers, using the distributed networks to provide a wide spectrum using the distributed networks to provide a wide spectrum of services etc.of services etc.
As a result the NGN technical means testing As a result the NGN technical means testing requires some new approaches. Therefore the WTSArequires some new approaches. Therefore the WTSA’’04 04 (Brasilia, Florianopolis, October 2004) opened for SG 11 (Brasilia, Florianopolis, October 2004) opened for SG 11 the new Question Q. 8/11.the new Question Q. 8/11.

Principle of NGN testing
At present the process of testing may be divided into the following stages
•• testing for conformancetesting for conformance•• testing for compatibilitytesting for compatibility•• testing for interoperabilitytesting for interoperability

Model network Model network a network which simulates the capabilities similar to those available in present telecommunication networks, has a
similar architecture and functionality and uses the same telecommunication technical means
Model Network for NGN testing
Dedicated Model NetworkDedicated Model Network Distributed Model NetworkDistributed Model Networkis composed of several model networks, two as a minimum, interconnected via communication channels and are used to perform complex tests for compatibility, interoperability, testing QoSparameters and etc.
is a fragment of the public telecommunication network which is not connected to other model networks and are used to perform testing for conformance, compatibility and etc.
