ITU-T U.30 FRENCH-1988 用于国际电路交换公众电报的信令状态

The Recommendation considering that the conditions in Recommendation U.1 concerning signalling in the international telex service, the specifications in Recommendation U.2 for standardization of dials and dial pulse generators in the international telex service, in Recommendation U.3 for the reduction of the effect of false calling signals, and in Recommendation U.5 on the characteristics of regenerative repeaters used in international calls, will hold good in the gentex network, except those referring specifically to manual or semi-automatic working. In some countries, indeed, no distinction is made between the gentex and the telex networks; that the differences between signalling conditions in the telex and the gentex networks are essentially due to the possibility of using overflow in the gentex network, and the absence of charges in it.

SIGNALLING CONDITIONS FOR USE IN THE INTERNATIONAL GENTEX NETWORK

ITU-T U.31 FRENCH-1988 电路交换公众电报业务中错误站点及/或站线的连接防护

The Recommendation considering that correct reception of the answerback code at the beginning and end of a telegram should safeguard the correct transmission of the telegram; that it accordingly becomes essential to provide adequate signalling for cases when a teleprinter is temporarily unable to participate in the international service, on account of paper trouble, faults, etc.

PREVENTION OF CONNECTION TO FAULTY STATIONS AND/OR STATION LINES IN THE GENTEX SERVICE

ITU-T S.14 FRENCH-1988 无线电报多址电传打字机系统中无用接收的抑制

The CCITT, considering that in a radiotelegraph system in which a radio teleprinter transmitter broadcasts messages simultaneously to a number of receiving stations, this broadcast is sometimes required only by a restricted number of these stations; that it is desirable in such cases to prevent the reception of the message at the other offices to avoid wastage of paper.

ITU-T U.41 FRENCH-1988 电报业务中的更改地址插入及呼叫转移

The Recommendation considering that, with fully automatic working between telex subscribers, it is desirable to envisage the possibility of: a fully automatic changed address interception facility, a fully automatic call redirection facility; that the operation of such facilities has an influence upon telex calls originated by other Administrations and therefore requires international standardization.

CHANGED ADDRESS INTERCEPTION AND CALL REDIRECTION IN THE TELEX SERVICE

CHANGED ADDRESS INTERCEPTION AND CALL REDIRECTION IN THE TELEX SERVICE

ITU-T U.43 FRENCH-1988 随后呼叫

The Recommendation considering that users of the telex service often have several messages ready to transmit at the same time to different subscribers and that it would therefore be an advantage for them to be able to transmit these messages one after the other, keeping the part of the communication chain already established in a seized condition and having the calls set up successively, without having to go through the whole procedure of setting up a new call for each message.

FOLLOW-ON CALLS

ITU-T U.44 FRENCH-1988 用于满足国际电报业务中广播目的的即时多址呼叫

The Recommendation considering that the definitions of multi-address and broadcast calls; (Supplement No. 2 to F-Series Recommendations); that new systems are capable of providing broadcast facilities, thereby permitting a telex subscriber to set up a call to a list of destinations such that signals transmitted by the originating subscriber are received virtually simultaneously by the called subscribers.
