CCITT is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a worldwide basis. The Plenary Assembly of CCITT which meets every four years, establishes the topics for study and approves Recommendations prepared by its Study Groups. The approval of Recommendations by the members of CCITT between Plenary Assemblies is covered by the procedure laid down in CCITT Resolution No. 2 (Melbourne, 1988). Recommendation F.89 was prepared by Study Group I and was approved under the Resolution No. 2 procedure on the 4th of August 1992. ___________________ CCITT NOTES 1) In this Recommendation, the expression “Administration” is used for conciseness to indicate both a telecommunication administration and a recognized private operating agency. 2) A list of abbreviations used in this Recommendation can be found in Annex A. © ITU 1992 All rights reserved. No part of this publication may be reproduced or utilized in any form or by any means, electronic or mechanical, including photocopying and microfilm, without permission in writing from the ITU. 2 Recommendation F.89 (08/92) Recommendation F.89 Recommendation F.89 (08/92) STATUS ENQUIRY FUNCTION IN THE INTERNATIONAL TELEX SERVICE (1992) 1 Introduction This Recommendation describes the facilities and operational requirements of a status enquiry function (SEF) within the international telex service which enables a subscriber of the international telex service to seek and be provided with information concerning the status of a message previously deposited into an interworking function (IWF) for the purpose of transmission to a user of another service on either a store-and-forward basis or store-and-retrieve basis. In some interworking cases, the SEF may also provide a message cancellation facility. 2 Scope The provisions of this Recommendation are limited to enquiries concerning messages handled by an IWF in accordance with the relevant F.80-Series Recommendations. Status enquiry in respect of messages deposited into a telex store and forward unit (SFU) for delivery to the international telex service are handled in accordance with Recommendation F.72. The provisions of this Recommendation should be applied to future implementations and, as far as possible, to existing implementations of IWF and SFU, in the latter case as an alternative to the provisions of Recommendation F.72 in respect of status enquiry. 3 Area of application 3.1 A status enquiry function is relevant in those interworking configurations which implement message delivery on a store-and-forward basis or store-and-retrieve basis, namely: – telex to telex (see Recommendations F.72/U.80/U.81); – telex to teletex (see Recommendations F.81/F.201/U.201); – telex to facsimile Group 3 (see Recommendations F.87/U.207); – telex to interpersonal messaging (IPM) (see Recommendations F.85/F.421/U.204); – telex to videotex (see Recommendations F.86/U.206); – telex to INMARSAT C (see Recommendations F.127/U.208). 3.2 In the context of this Recommendation, “DELIVERED” should be interpreted in accordance with Table 1/F.89. 4 Service provided by SEF 4.1 Information about message status 4.1.1 The SEF should provide information about the status of messages for which message reference information had been provided at the time of message deposit in accordance with the relevant F- Series Recommendations. The receipt of message reference information generally will have been effected by the use of a two-stage access, using either the input transaction accepted for delivery (ITD) or input message acknowledgement (IMA) procedure. It should be noted that message reference information is also provided in the particular case of single-stage access from the international telex service to the INMARSAT Standard-C system in accordance with Recommendation F.127. Recommendation F.89 (08/92) 1 Message status information may also be provided through the use of a journal facility, which may also be applied in the single-stage access case where there may be an absence of supporting message reference information.
