2       Objectives and Scope
The ENUM trial in China is carried out with the following objectives:
       Set up a testbed including the ENUM provisioning and application to demonstrate the core
        concepts and significance of ENUM ;
       Study the technical framework for ENUM implementation under the country code 86 ;
       Study the policy, regulation and security problem brought by ENUM;

The ENUM trial is led by the government, i.e. the Ministry of Information Industry (MII) of China.
One ENUM trial leading team and five study groups have been established after the first
coordinating meeting of ENUM trial in March, 2002. The ENUM trial leading team is in charge of
the overall study program and working plan. It is consisted of the officials of MII and leaders of the
