		      ITU-T RECOMMENDATION SUMMARY


Rec. No. : D.176

Title :	Transmission in encoded form of telephone reversed charge 
	billing and accounting information

Study Group : III - Tariff and Accounting Principles

Version : Revised

Date of adoption : 1992

Notes :	


Under the provisions of Recommendation D.174 where the chargeable 
duration of a reversed charge telephone call is determined in the 
outgoing country, the details of the call should be transmitted 
promptly to the distant Administration to enable it to perform 
customer billing and in certain circumstances initiate international 
accounting.

A growing number of Administrations are processing telephone call 
data using computer based accounting systems. Information is drawn 
from traffic history tapes or from manually encoded data such as 
telephone tickets. It is usual, at present, to convert computer 
output from this processing to conventional printed accounts for 
dispatch to other Administrations. Where the receiving Administration 
also uses computer facilities, however, this information has to be 
re-encoded for further processing.

Transmission of data in encoded form avoids the decoding/reencoding 
step. It also offers a faster transfer of information than by printed 
forms through the mail. The latter remains true even if the 
forwarding Administration has prepared the data by manual/mechanical 
means.

The aim of Recommendation D.176 is to present a standard data record 
format for the various elements of information to be transferred.
