3、s at other international or national exchanges may also have access to them by meansof an automatic transit device. In such circumstances these international or national exchanges must be treated as thoughthey were a controlling exchange, as far as setting up calls is concerned.12 controlling operat

4、orF: opratrice directriceS: operadora directoraThe controlling operator is the outgoing operator in the controlling exchange who operates the internationalcircuit. The controlling position is the position used by the controlling operator.4 Fascicle II.2 - Rec. E.100Note - However, it may happen that

5、 the outgoing international circuit is also operated by an operator in aninternational or even a national exchange. If this is so, the latter operator is considered as controlling operator.13 successive phases of a callF: phases successives dune communicationS: fases sucesivas de una comunicacinThe

6、characteristic instants in the successive phases of the setting-up of an international telephone call in themanual or semiautomatic service are distinguished as follows:t0the caller has placed his request;t1the controlling operator has received all of the call details;t2the controlling operator has

7、made the first attempt to set up the call (this instant corresponds practically tothe seizure of the international circuit);t3the called number has replied or the caller has been informed why the call cannot be connected;t4the called person (or called extension) has been obtained or the caller has b

8、een informed why the callcannot be connected (the instant is only significant for personal calls);t5the end of the conversation, generally when the caller replaces the receiver;t6disconnection, normally when the international circuit is released by the operator.Note - In automatic service it is in g

9、eneral difficult to define all the characteristic instants specified above,either because it is impossible to distinguish between them with accuracy or because of differences between theswitching systems used. It is, however, possible to define the total setting-up time (see definitions 17).14 durat

10、ion of a call (conversation time)F: dure de la conversationS: duracin de conferenciaThe interval between the instant the call is actually established between the calling and the called stations andthe instant the calling station gives the clearing signal (or the instant when, although the caller has

11、 not replaced hisreceiver, the call is:- in manual or semiautomatic service, officially cleared down by an operator,- in fully automatic service, cleared down after some slight delay by the action of the called subscribersclear-back signal).The time interval between:a) t5- t3is the duration of a sta

12、tion call;b) t5- t4is the duration of a personal call.15 chargeable duration - charged durationF: dure taxable - dure taxeS: duracin tasable - duracin tasada15.1 The time interval on which the charge for a call is based is called the chargeable duration.15.2 The chargeable duration is equal to the d

13、uration of the call reduced in manual or semiautomatic service, ifnecessary, to make allowance for any interruptions or other difficulties which might have occurred during the call.15.3 The duration of a call for which the charge is paid by the calling subscriber (or the called subscriber in the cas

14、eof a collect call) in the case of manual or semiautomatic operation, is the chargeable duration rounded upwards to thenext whole minute.Fascicle II.2 - Rec. E.100 516 holding time of an international circuitF: dure doccupation du circuit internationalS: duracin de ocupacin de un circuito internacio

15、nalThe time interval t6- t2during which the circuit is used is the holding time of the international circuit.This interval includes in particular the call duration, the operating time and the time taken to exchange serviceinformation.Note - The term “operating time” is meant to cover the time taken

16、both by operators and switching equipment.17 answering time of operators; request transmission time; delay time; setting-up times of an international callF: dlai de rponse des opratrices; dlai de transmission de la demande; dlai dattente; dlaidtablissement dune communication internationaleS: demora

17、en contestar de las operadoras; tiempo de transmisin de la peticin; demora; tiempo deestablecimiento de una comunicacin internacional17.1 At the outgoing international exchange, the answering time of operators is the interval between the end of thetransmission of the calling signal and its answer by

18、 an operator at the distant international exchange.At the incoming international exchange, the answering time of operators is the interval between theappearance of a calling signal on a position or group of positions at that exchange and its answer by an operator.17.2 The request transmission time i

19、s the time interval (t1- t0) taken in passing the call request to the controllingoperator.17.3 The time interval (t2- t1) is the delay to which the call is subject at the controlling exchange.The caller is generally informed of this delay.17.4 The setting-up time of a station call is the time interval (t3- t1). The total setting-up time of a personal call isthe time interval (t4- t1). These times include any delay at the outgoing international exchange.
