Recommendation D.400 R

Fascicle II.1 - Rec. D.400 R

ACCOUNTING RATES¹⁾ APPLICABLE IN

TELEPHONE RELATIONS BETWEEN COUNTRIES IN LATIN AMERICA

When, in full exercise of their sovereignty, the Administrations of the countries of Latin America negotiate agreements to determine the accounting rates to be applied in their telephone relations, it is recommended that they consider the provisions below:

1 Long-distance relations

It is desirable to achieve some coordination and, as far as possible, standardization of the accounting rates applicable in telephone relations over similar distances between countries of the Latin America region. To this end, it has been considered advisable to establish a scale of accounting rates based on distance, with steps corresponding to distance ranges. This scale was established on the basis of:

a) accounting rates already in use;

b) the principle that the increase in rate at each step in the tariff scale is proportionately less the greater the distance, since the costs which vary with distance do not do so in direct proportion to the distance;

c) the fact that the distance ranges become broader with distance;

d) the adoption of the tariff step corresponding to the greatest distance (more than 4000 km) as the reference step and the application to it of a maximum rate per minute of 12.2440 gold francs;

e) the attribution of a coefficient to each distance range, the coefficient 1 being attributed to the reference step and a decreasing coefficient to the other steps.

For each step in the tariff scale it is recommended that the maximum accounting rates below be applied:

Telephone relations between countries of Latin America through direct circuits via satellite are included – for international accounting purposes – in the highest rate above, regardless of the geodesic distance separating the international centres involved.

2 Frontier telephone relations

The determination of accounting rates and collection charges in frontier telephone relations between countries of Latin America should be governed by the following provisions:

a) Local connections

For telephone connections using no trunk exchange of any type, the local telephone rates of the originating exchange will be applied, with no remuneration of the receiving end.

 

b) Trunk connections

For regional telephone connections using some type of trunk exchange, accounting rates and collection charges will be established by agreement between Administrations; collection charges should under no circumstances exceed the collection charges approved for telephone calls between the main exchanges of each of the two countries.

Whenever possible, frontier telephone relations should not entail the exchange of international accounts, and the collecting Administration should keep the entire amount collected. It should undertake, however, to supply all traffic information required to the Administration of the country of destination.
