This Recommendation specifies the organizational elements necessary for this purpose, and outlines the functions and responsibilities of each element. С СOnly those organizational elements vital to the network management development, planning, implementation and control of the international network are dealt with in the Recommendation. It is recognized that other functions must necessarily be carried out within the network management organization, either in support of the functions specified below or in connection with the management of the national network. а H аС СIt is also recognized that Administrations may not wish to assign each element to a separate staff or create a separate organization. Administrations are, therefore, afforded the freedom to organize such functions in a manner which best suits their own situation and the level of development of network management. ‚У У2ТX ТInternational network management Р-Р organizationФ ФЦЦ 2.1С  СAs far as international cooperation and coordination are concerned, network management should be based on an organization comprising the а H аfollowing elements, all of which should exist in each country practicing international network management: Та ТТ№ ТС€ Сa)СpСnetwork management planning and liaison;ЦЦ Та ТТ№ ТС€ Сb)СpСnetwork management implementation and control;ЦЦ Та ТТ№ ТС€ Сc)СpСnetwork management development.ЦЦ а H аС СEach element represents a set of functions and reponsibilities, and are further defined in РSРS 3 to 5. а H ааЬџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџH јP Ј XА`ИhР!(#џџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџЬа2.2С   СAt the discretion of the Administration concerned, the elements defined in РSРS 3 to 5 below can be grouped together in a single organizational entity, for example, an International Network Management CentreйT€ International Network Management Centreб cмˆ4 PŽТ бTй. This is likely to be the most convenient and efficient approach where the level of development and degree of practice of network management is high. Where such an approach is not possible, or is impractical, international network management functions could be carried out at locations where related activities are performed.
