Question 1/I - Regulatory provisions (revised and continuation of Question 1/I, 1985-1988) Considering (a) that proposals concerning a broad international regulatory framework for existing and new telecommunication services have been submitted to the World Administrative Telegraph and Telephone Conference (Melbourne, 1988); (b) that the decisions of the WATTC and/or the subsequent Plenipotentiary Conference (Nice, 1989) may require amendment of CCITT Recommendations, a study should be made of the following points: 1. the possible need to amend or draft new provisions concerning operational and service policy aspects of specific services or of services in general, taking into account the decisions of competent Conferences; 2. continuation of the study of general operational principles for new services, in particular where such principles may need to be different from those for existing services that use the same underlying transport mechanism.
