11、y over the years, the role of the operator has remained an important element in the provision of services to customers. Recognizing the higher standards for reliability of telephone communications for voice and data service, the following “Instructions” are designed to prepare the international oper

12、ator to handle requests for assistance in the successful connection and completion of international calls. To this end, Administrations should: - attach the greatest importance supervisors and staff operating and to the professional training of international operator positions, - make every effort t

13、o see that these “Instructions” are diligently applied. The attention of Administrations is drawn to ITU-T Recommendations E. 140 (Operator-assisted telephone service), E. 105 (International telephone service), F. 17 (Operational aspects of service telecommunications). More detail on the operational

14、 principles in the international public telephone service will be found in the E-series Recommendations.

15、nd adherence to these “Instructions” which will greatly facilitate the effective operation of the international telephone service. -8- Preliminary notes For the definition of the “Instructions” see the International Telecommunication Regulations (Melbourne, 1988), Article 2. See Recommendation C.3 f

16、or the general principles concerning the “Instructions”, including arrangements for their periodic amendment and the date of entry into effect of new or amended “Instructions”. In these “Instructions”, the expression “Administration” is used for shortness to indicate both a telecommunication Adminis

17、tration and a Recognized Private Operating Agency (RPOA). Customers and operators, of course, are both male and female. The use of pronouns and gender-specific forms of words throughout these “Instructions” carry no implications, and where one gender form appears, the other is also implied. I dl il

19、ernational telephone circuit) which switches calls destined to or originating from another country is called an international exchange Administrations shall designate or, in case of joint utilization, concur in designating the exchanges in the territory they service which are to be regarded as inter

20、national exchanges Article 2 International transit exchange An international exchange which switches calls both originatihg and terminating in other countries is called an international transit exchange. Article 3 Controlling exchange m 0- il -I W w I FI 3 FI w r z E U W E t- I c H n t- VI 1. order

The Administrations concerned shall agree among themselves to 3. As a general rule, they shall select for this purpo

22、se: 3.1 operating that circuit on the calling party side; when a single international circuit is used, the international exchange 3.2 when two or more international circuits are used: a) either the international exchange which has access to the first international circuit on the calling party side;

23、or b) the international transit exchange designated by joint agreement of the Administrations concerned. Nofe - It may be that the intemational circuits are not operated exclusively by operators at the international exchange where they end; operators at other international or national exchanges may

24、also have access to them by means of an automatic transit device. In such circumstances these international or national exchanges must be treated as though they were a controlling exchange, as far as setting up calls is concerned. Article 4 Controiling operator The controlling operator is the outgoi

25、ng operator in the controlling exchange who operates the international circuit. The controlling position is the position used by the controlling operator. Tc u) r I d r- i1 d O il r Vl ru Q f n m r r I+ w I i1 i1 w z E U w E c I il t- H n c v) Note - However, it may happen that the outgoing internat

26、ional circuit is also operated by an operator in an international or even a national exchange. If this is so, the latter operator is considered as controlling operator. - 13 - Article 5 Telephone circuit (International or trunk circuits) 1. between two exchanges (manual or automatic) is called a tel

A circuit is called an ?international circuit? when it directly connects 3. national circuits. The term ?trunk circuit? is reserved for the designation of exclus

28、ively Article 6 Traffic routes 1. A route comprises the circuits to be used for international telephone traffic between two given international exchanges. They are designated by agreement between Administrations. A distinction is made between primary and secondary. 1.1 destination. Primary route: th

29、e circuit group normally used for reaching the called d a m o- o- 4 -1 W z w I il I il w c I 3 f- H n I- to 1.2 Secondary route or routes: the circuit group to be used when the primary route is congested, or when the transmission on the primary route is not sufficiently good, or it is outside the no

30、rmal hours of service on the primary route. - 14 - Article 7 Telephone call A telephone call is the interconnection of two telephone stations or terminals. I Note - A telephone call can be made using the automatic or operator service. Article 8 Telephone message A telephone message is an effective c

31、all over a connection established either automatically or by operator assistance between the calling and the called stations or terminals. A telephone connection may also be Used to carry data or fax messages. Article 9 Automatic service In the automatic service the call is established without the a

32、ssistance of an operator. The user enters the number necessary to obtain the called station or terminal. - 15 - Article 10 Operator service In the operator service the call is established with the assistance of an operator. The call can be established semi-automatically or manually: 1) in semi-autom

33、atic operation an international operator establishes a call with the called station or terminal; 2) in manual operation, a call is established by the originating and terminating international operators, possibly with the assistance of one or more intermediate operators. Article 11 Call request The f

34、irst application made by the caller for a telephone call is called the call request. The successive Article 12 Successive phases of a caii steps normally taken in the setting-up of an international telephone call in the manual or semi-automatic service are defined as follows: - - the caller has plac

35、ed his request; the controlling operator has received all of the call details; tl - t2 the controlling operator has made the first attempt to set up the call; - 16 - - t3 the called number has replied or the caller has been informed why the call cannot be connected; - t4 the called person (or called

36、 extension) has been obtained or the caller has been informed why the call cannot be connected (this step is only significant for personal calls); - t5 the end of the call is generally when the caller replaces the receiver; - disconnection, normally when the international circuit is released by the

37、operator or by the equipment of the international exchange of the calling party side. Article 13 Request transmission time The time interval ti-to is the time taken in passing the call request to the controlling operator. Article 14 Delay time 1. controlling exchange. The time interval t2-tl is the

38、delay to which the call is subject at the u w I w PL i- l 3 I- H Fi i- V) 2. The caller is generally informed of this delay. - 17 - Article 15 Setting-up time of a call 1. The time interval: a) t3-tl is the setting-up of station call; b) h-tl is the total setting-up time of a personal call. These ti

39、mes include any delay at the outgoing international exchange. 2. Article 16 Duration of a call The time interval: a) t5-t3 is the duration of a station call; b) t5-t4 is the duration of a personal call. Article 17 Chargeable duration 1. chargeable duration. The time interval on which the charge for

40、a call is based is called the a- m I a- 9 r- a- FI 9 o il n- vl m 11 Q 3- I m a- o- il 1 u w I FI 3- FI Irl 2 E U w E I- l 3 c H FI I- l4 2. The chargeable duration is equal to the duration of the call reduced in manual or semi-automatic service, if necessary, to make allowance for any interruptions

41、 or other difficulties which might have occurred during the call. - 18 - Article 18 Charged duration 1. In the manual and semi-automatic service the charged duration of a call for which the charge is paid by the calling subscriber (or the called subscriber in the case of a collect call) is the charg

42、eable duration rounded upwards to the next whole number of minutes. 2. In automatic service other arrangements could be adopted in accordance with the ITU-T Recommendations. Article 19 Holding time of an international circuit 1. The time interval k-tz is the holding time of the international circuit

43、. 2. time and time taken to exchange service information. This interval includes in particular the call duration, the operating Note - The term “operating time” is meant to cover the time taken by both operators and switching equipment. Article 20 Answering time of operators on an international circ

44、uit m u- r il 1 W W I il I il W U W ni c- I H n c- VI 1. At the outgoing international exchange, the answering time of operators is the interval between the end of the transmission of the calling signal and its answer by the operator at the distant international exchange. - 19 - 2. At the incoming i

45、nternational exchange, this is the interval between the appearance of a calling signal on a position at that exchange and its answer by an operator. Article 21 Demand operating 1. In demand operating (manual or semi-automatic), after *e request has been recorded in the outgoing international exchang

46、e, an immediate attempt to set up the call is made by the operator at this exchange who took the request. 2. A distinction is made between: 2.1 Manual demand operating: There are two aperating methods: a) direct manual demand operating In this method of operating, the operator in the outgoing intern

47、ational exchange speaks with the called party directly; b) indirect manual demand operating In this method of operating, the operator at the incoming international exchange always acts as an interpreter between the operator in the outgoing international exchange and the called Party. 2.2 Semi-automa

48、tic demand operating m o- o- il 4 W W I FI 3- il w W oc I- l 3 I- H Fi I- VI In this method of operating, the .operator in the outgoing international exchange controls the automatic switching operations to obtain either the called station, or an operator in the incoming or transit international exch

49、ange (or an operator in a manual exchange in the country of destination). - 20 - Article 22 m m I- 111 F F n- FI Outgoing preparation operating In outgoing preparation operating, after the request is recorded by an operator in the outgoing international exchange, another operator in the exchange sets up the call. After the requests have been put in order at the exchange, the controlling operator sees to it that the calling station is connected on the international circuit without loss of time; the call is then set up at the called end as in the case o
