- Recommendation F.41
- Recommendation F.41
- INTERWORKING BETWEEN THE TELEMESSAGE SERVICE AND
- THE INTERNATIONAL PUBLIC TELEGRAM SERVICE
- 1 Introduction
- 1.1 The International Telecommunication Regulations (Melbourne, 1988), Article
- 4.3 c), deal with the requirement to provide at least a form of telecommunication
- which is reasonably accessible to the public, including those who may not be
- subscribers to a specific telecommunication service. Traditionally the
- international public telegram service has been the most common means of filling
- this need.
- 1.2 Resolution No. 6 (World Administrative Telegraph and Telephone Conference,
- Melbourne, 1988) resolves that provision should be made to allow continued
- availability of traditional services as perceived by the customer, although the
- communication infrastructure used to provide that service may vary.
- In continuing to provide a telegram-type service, Administrations should
- agree either to operate a telegram service in accordance with Recommendation F.1,
- a telemessage service in accordance with Recommendation F.40, both the telegram
- and the telemessage services, or to come to some other bilaterally agreed
- arrangement.
- 1.3 This Recommendation defines the procedure that shall be followed for
- interworking between the telemessage service and the international public
- telegram service, where Administrations provide one service or the other and no
- other specific agreement has been reached.
- 2 Basic interworking principles
- 2.1 A service provider operating an international public telemessage service
- shall provide the capability of operating in conjunction with the international
- public telegram service in order to provide a replacement for ordinary private
- telegrams at least.
- 2.2 Member Administrations will make separate operational arrangements to
- ensure adequate handling of SVH, ETATPRIORITE, ETAT, OBS and RCT messages. Such
- arrangements which may involve the use of the other telecommunication services
- (e.g. telex) are not covered by this Recommendation.
- 2.3 In the absence of any other bilateral agreement, the relevant telegram
- operational procedures defined in Recommendation F.1 shall apply in both the
- telegram to telemessage and the telemessage to telegram directions, with the
- exceptions described in S 3 below.
- 2.4 The charging and accounting principles for interworking between the
- telemessage service and the international telegram service will be defined in the
- D-Series Recommendations.
- 3 Operational procedures
- 3.1 If no other agreement exists, only F.31 format shall be used for the
- transmission of messages between the Administrations concerned.
- 3.2 In the direction telegram to telemessage the service indication
- TELEMESSAGE and the priority/tariff indicator CT shall be used.
- 3.3 In the same direction, special arrangement may be made for de luxe form,
- in which case the service indication LXx shall be used as specified in
- Recommendation F.50. No other special services or optional classes are admitted.

- 3.4 In the telegram to telemessage direction, the origin Administration should
- be aware of the 35 text line limit per message in the telemessage service as
- defined in Recommendation F.40.
- 3.5 In the telegram to telemessage direction the rules laid down in
- Recommendation F.1 for the counting of actual words shall apply, but the number
- of chargeable words may be omitted from the preamble line and the pilot line may
- show either the number of actual or chargeable words (at the discretion of the
- origin Administration).
- 3.6 In the telemessage to telegram direction the wordcounts and their
- presentation shall be in accordance with Recommendation F.1.
- 4 Service documents
- 4.1 In view of S 1.2 above Administrations should inform the Secretary-General
- of their method(s) of providing a telegram-type service. The Secretary-General is
- invited to include this information in the General information relating to the
- operation of the international telegraph, data transmission and Telematic
- services.
