Recommendation C.3







INSTRUCTIONS FOR INTERNATIONALCOMMUNICATION SERVICES

	The CCITT,

considering

	(a)	Resolutions Nos. 1 and 3 of the World Administrative Telegraph and Telephone Confer-
ence (Geneva, 1973) concerning the Instructions for the Operation of the International Public Tele-
gram Service and Telex Operation and Tariff Principles, respectively.

	(b)	that Article 26 of the Radio Regulations (Geneva, 1979) requires the Manual for Use by 
the Maritime Mobile and Maritime Mobile–Satellite Services to contain the Instructions for the Inter-
national Public Telegram Service and the International Telephone Service;

	(c)	that, in the draft International Telecommunication Regulations submitted by the CCITT 
for consideration at the World Administrative Telegraph and Telephone Conference (Melbourne, 
1988), Article 1 refers to the need to comply with Recommendations and Instructions, while not 
implying that they have the same legal status as Regulations;

	(d)	that, in the same draft Regulations, Instructions are defined as consisting of provisions 
from a CCITT Recommendation or Recommendations dealing with practical operating procedures 
for the handling of telecommunication traffic (e.g. acceptance, transmission, accounting);

	(e)	that, provisions to be designated as Instructions are so designated for one or more of the 
following reasons:

–	their observance on a world–wide basis is of particular importance for the orderly and effi-
cient operation of the international telecommunication service(s) concerned;

–	it may be convenient to publish them as a separate booklet for use by operators;

–	the provisions (or subsequent amendments to them) may need to enter into effect at a speci-
fied time throughout the world;

unanimously declares the view

	(1)	that Administrations should apply the detailed operational procedures laid down in the 
Instructions, which are constitued as shown in Table 1/C.3 below;

	(2)	that when modifications are made to the text of Instructions, the Plenary Assembly 
approving them should also indicate the date of their entry into force, in order to facilitate their 
world–wide observance in a coordinated manner. In setting this date, due account should be taken of 
the time required for the publication of the modifications, as well as for their distribution to the oper-
ation services concerned.
