Rec. No. : D.11

Title :	Special tariff principles for international packet-switched
	public data communication services by means of the virtual 
	call facility

Study Group : III - Tariff and Accounting Principles

Version : Revised

Date of adoption : 1991

Notes :	


Recommendation D.11, which should be applied in conjunction with the 
provisions of Recommendation D.10, sets out the special tariff 
principles intended for application to the international 
packet-switched public data communication service by means of the 
virtual call facility.

Since this is a rapidly developing field at the present time in terms 
of the diversity of application, flexibility is essential.

After defining the virtual call (switched connection), 
Recommendation D.11 precises what calls are chargeable, what are the 
tariff components (netword access and network utilization components) 
and what are the rules for international accounting.
