3、dministrations should agree to apply one ofthe following three methods for the establishment of their international accounts:2.3.1.1 by basing them on the chargeable durations recorded for subscribers, when the outgoing Administrationpossesses equipment capable of showing these durations;2.3.1.2 by
4、basing them on the total (actual) duration of calls measured on international circuits in the outgoinginternational exchange by means of appropriate meters. When, in relations where signalling systems are used that makeit impossible to assess the call durations without excessive complications, the A
5、dministrations measure the totaloccupation time of the outgoing circuits, a correction factor should be applied to the traffic figures so as to assess, intotal actual call duration, the traffic that is to serve as the basis for preparing the accounts. The corrections to be appliedshould be determine
6、d by agreement between the Administrations concerned;2.3.1.3 accounting may be dispensed with, or a lump-sum settlement applied, by agreement between theAdministrations concerned.2.3.1.4 In the case of 2.3.1.1 and 2.3.1.2, accounting shall be based on the sum of minutes and, if appropriate,fractions
7、 of minutes for all calls (of the given relation) during the accounting period in question, normally one month,the total being rounded up to whole minutes (e.g. 1.3 + 2.4 + 1.1 + 5.6 = 10.4 min which in the monthly account shallbe rounded up to 11 min).2.3.2 If a group of circuits is used both for g
8、entex operation and for automatic telex operation, the method describedunder 2.3.1.2 may be allowed only if the meters concerned are not operated in the case of gentex calls.2.3.3 If a circuit is capable of fully automatic and semi-automatic use, and if, further, the method mentioned under 2.3.1.2 i
9、s applied, the equipment in the international outgoing exchange should be capable of identifying semi-automatic calls so that the meters concerned are not operated in the case of semi-automatic calls._1)See also Recommendation F.61.2 Fascicle II.1 - Rec.

10、argeable duration of a call3.1.1 The chargeable duration of a telex call begins at the moment the connection is established between the callingand the called subscribers.3.1.2 It ends at the moment when the clearing signal given by the calling or called subscriber is transmitted over theinternationa
11、l circuit. To this end, the international telex position must be able to receive the clearing signal from bothsides.3.2 Methods of chargingWith manual or semi-automatic operation:3.2.1 any telex call of three minutes duration or less shall be charged as for three minutes;3.2.2 when the duration of a
12、 call exceeds three minutes, a charge per minute shall be made for the period in excess ofthe first three minutes. Any fraction of a minute shall be charged as for one minute.3.3 Establishment of international accountsThe international accounts shall be based on the chargeable minutes as defined under 3.2.1 and 3.2.2.
