This file is an extract from the Blue Book. While the presentation and layout of the text might be slightly different from the Blue Book version, the contents of the file are identical to the Blue Book version and copyright conditions remain unchanged (see below). 2 In this Recommendation, the expression “Administration” is used for conciseness to indicate both a telecommunication administration and a recognized operating agency. © ITU 1988, 1993 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. Recommendation F.351 GENERAL PRINCIPLES ON THE PRESENTATION OF TERMINAL IDENTIFICATION TO USERS OF THE TELEMATIC SERVICES The CCITT, considering (a) that the terminal identification (TID) in the telematic services should provide the called subscriber not only with an unambiguous identification of the calling subscriber, but also with the essential information needed to establish a call to the former; (b) that transfer of network addresses, terminal identifications and other session management functions are covered in Recommendations specific to individual networks and telematic services; (c) that detailed provisions on TIDs and network addresses may be also found in specific Telematic service and network Recommendations and no modifications are necessary to the information carried by the communications protocol; (d) that, from the operational viewpoint, it is acceptable for a subscriber to add selection digits to those presented in the TID, recommends that the following general principles on the identification of terminals in the telematic services (and, as appropriate, other terminals) should be applied to all new equipment, and to all existing equipment1). 1 The TID for telematic on the PSTN shall precede the telephone country code with the escape code “9”. 2 The TID for telematic terminals on the ISDN shall precede the country code with the escape code “0”. 3 Table 1/F.351 shows examples of TIDs for telematic terminals on the CSPDN, PSPDN, PSTN and ISDN. The table also includes the dialling sequences from a terminal on one type of network to terminals on other types of networks. It should be noted that it may be necessary to instruct users NOT to dial the escape code “9” for calls from PSTN and ISDN to PSTN, and “0” from PSTN and ISDN to ISDN. 1) The applicability of TID concept for existing G2/G3 terminals is not mandatory. In new G3 terminals the possibility to implement TID is to be encouraged. Fascicle II.5 - Rec.

Note 2 – On calls from PSTN to PSTN and ISDN, and from ISDN to PSTN and ISDN the escape codes “9” and “0” may not be acceptable to the national PSTN and ISDN. 2 Fascicle II.5 - Rec. F.351
