4、or speech information Transfer, to the bearer capabilities and functions required to provide the service requested by the user, different in the countries concerned, due to the structure of the national digital networks in operation, network capabilities and Functions, - that the basic utilization c
5、harges applied to these services should be cost oriented and be determined according - that the respective costs incurred by the Administrations to provide these types of services may be significantly - that in principle there should be no charging or accounting discrimination between services sequi

A Further differentiation on charging levels
8、 may be set For those services requiring 3.1 kHz audio capabilities. 2. In principle, measurement of a call For charging pusposes should be based on duration and should commence when the information channel is open for communication. O B. ACCOUNTING PRINCIPLES 1.
