8、commendation H.248.35 was approved on 8 January 2005 by ITU-T Study Group 16 (2005-2008) under the ITU-T Recommendation A.8 procedure. ii ITU-T Rec. H.248.35 (01/2005) FOREWORD The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications
9、. The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of ITU. ITU-T 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 World Telecommunication St
10、andardization Assembly (WTSA), which meets every four years, establishes the topics for study by the ITU-T study groups which, in turn, produce Recommendations on these topics. The approval of ITU-T Recommendations is covered by the procedure laid down in WTSA Resolution 1. In some areas of informat
11、ion technology which fall within ITU-Ts purview, the necessary standards are prepared on a collaborative basis with ISO and IEC. NOTE In this Recommendation, the expression “Administration“ is used for conciseness to indicate both a telecommunication administration and a recognized operating agency.
12、 Compliance with this Recommendation is voluntary. However, the Recommendation may contain certain mandatory provisions (to ensure e.g. interoperability or applicability) and compliance with the Recommendation is achieved when all of these mandatory provisions are met. The words “shall“ or some othe
13、r obligatory language such as “must“ and the negative equivalents are used to express requirements. The use of such words does not suggest that compliance with the Recommendation is required of any party. INTELLECTUAL PROPERTY RIGHTS ITU draws attention to the possibility that the practice or implem
14、entation of this Recommendation may involve the use of a claimed Intellectual Property Right. ITU takes no position concerning the evidence, validity or applicability of claimed Intellectual Property Rights, whether asserted by ITU members or others outside of the Recommendation development process.
15、 As of the date of approval of this Recommendation, ITU had received notice of intellectual property, protected by patents, which may be required to implement this Recommendation. However, implementors are cautioned that this may not represent the latest information and are therefore strongly urged
16、to consult the TSB patent database. ITU 2005 All rights reserved. No part of this publication may be reproduced, by any means whatsoever, without the prior written permission of ITU. ITU-T Rec.

32、D: norm (0x0006) Description: Applies the signal to direct the phone to enable the DTMF keypad. This signal is also used to enable speech path on CSP (coin semi-postpay) phones after a coin deposit, and to reset the coin totalizer. Signal type: Brief Duration: Provisioned 5.3.6.1 Additional paramete
33、rs None. 5.4 Statistics None. 5.5 Procedures The cpres, cpartpres, creturn and ccollect signals prompt the coin phone to return a response indicating whether coins are present in the temporary storage area or not. In order to return this information to the MGC, the MGC should include the cqresp even
34、t in the Events Descriptor when applying one of the four primary coin signals. The coin phone is generally provisioned with the tariff rate for calls originating from the terminal. This means that the MGC only needs to be signalled about the presence or absence of coins, and if the coin total is suf
35、ficient to enable service. CDF terminals require coin deposit prior to making a connection. Typically, coins are requested after dialling if the coin total in the terminal is insufficient for the call. CSP terminals require coin deposit after establishing the connection, but prior to enabling voice
36、path. Coins are requested after connection based upon the tariff rate of the call. The signals here correspond to those used to perform coin detection and collection. For further information, consult the appropriate national coin-operated phone specifications. Printed in Switzerland Geneva, 2005 SER
