2、nderstandings between manufacturers and purchasers, facilitating interchangeability and improvement of products, and assisting the purchaser in selecting and obtaining with minimum delay the proper product for their particular need. The existence of such Standards and Publications shall not in any r
3、espect preclude any member or non-member of TIA from manufacturing or selling products not conforming to such Standards and Publications. Neither shall the existence of such Standards and Publications preclude their voluntary use by Non-TIA members, either domestically or internationally. Standards
4、and Publications are adopted by TIA in accordance with the American National Standards Institute (ANSI) patent policy. By such action, TIA does not assume any liability to any patent owner, nor does it assume any obligation whatever to parties adopting the Standard or Publication. This Standard does
5、 not purport to address all safety problems associated with its use or all applicable regulatory requirements. It is the responsibility of the user of this Standard to establish appropriate safety and health practices and to determine the applicability of regulatory limitations before its use. (From

7、evelopment or any editing process. The use or practice of contents of this Document may involve the use of intellectual property rights (“IPR”), including pending or issued patents, or copyrights, owned by one or more parties. TIA makes no search or investigation for IPR. When IPR consisting of pate
8、nts and published pending patent applications are claimed and called to TIAs attention, a statement from the holder thereof is requested, all in accordance with the Manual. TIA takes no position with reference to, and disclaims any obligation to investigate or inquire into, the scope or validity of
9、any claims of IPR. TIA will neither be a party to discussions of any licensing terms or conditions, which are instead left to the parties involved, nor will TIA opine or judge whether proposed licensing terms or conditions are reasonable or non-discriminatory. TIA does not warrant or represent that
10、procedures or practices suggested or provided in the Manual have been complied with as respects the Document or its contents. If the Document contains one or more Normative References to a document published by another organization (“other SSO”) engaged in the formulation, development or publication
11、 of standards (whether designated as a standard, specification, recommendation or otherwise), whether such reference consists of mandatory, alternate or optional elements (as defined in the TIA Engineering Manual, 4thedition) then (i) TIA disclaims any duty or obligation to search or investigate the
12、 records of any other SSO for IPR or letters of assurance relating to any such Normative Reference; (ii) TIAs policy of encouragement of voluntary disclosure (see Engineering Manual Section 6.5.1) of Essential Patent(s) and published pending patent applications shall apply; and (iii) Information as
13、to claims of IPR in the records or publications of the other SSO shall not constitute identification to TIA of a claim of Essential Patent(s) or published pending patent applications.

DP applies on
23、ly to digital modes of operation. A call requesting DP, while DP is not available, may be rejected by the system. Applicability to Telecommunications Services DP is applicable to ADS and G3 Fax. 1.1 Normal Procedures with Successful Outcome Authorization DP may be generally available or may be provi
24、ded after prearrangement with the service provider. Deauthorization DP may be withdrawn at the subscribers request or for administrative reasons. Registration DP has no registration. Deregistration DP has no deregistration. Activation DP may be activated upon authorization. It may also be Demand act
25、ivated with an AT command. A command may also specify the DP algorithm to be used. Deactivation DP shall be deactivated upon deauthorization. It may also be Demand deactivated with an AT command. Invocation The feature is invoked at or after call set up, if DP is active, and if it is supported by th
26、e current serving system.

27、 data is protected. Call Detail Record The system should record call detail information for the following: a. DP usage duration for each system involved. b. Type of data privacy applied. c. DP activation activities and events. d. DP deactivation activities and events. See DMH for the specific inform
28、ation to be included for each element. 1.2 Exception Procedures or Unsuccessful Outcome Registration None identified. Deregistration None identified. Activation None identified. Deactivation None identified. Invocation For data calls that request privacy during call set up, but privacy is unavailabl
29、e, one of the following shall occur: The system should provide an indication to the subscriber that DP is not available and continue the call without privacy. Upon finding that DP is unavailable, the subscriber may release the call. The system should provide an indication to the subscriber that DP i
30、s not available and may deny the call.

31、p, but privacy is unavailable, one of the following shall occur: The system should provide an indication to the subscriber that DP is not available and continue the call without privacy. Upon finding that DP is unavailable, the subscriber may release the call. The system should provide an indication
32、 to the subscriber that DP is not available and may release the call. Exceptions While Roaming DP may not be supported by all systems (e.g., specifically those systems offering only analog services), or digital systems not supporting the requested DP algorithm. Exceptions During Intersystem Handoff
33、DP may not be supported by all systems (e.g., specifically those systems offering only analog services, or digital systems not supporting the requested DP algorithm). In such a case, the call may be terminated (e.g., handoff from the Anchor MSC supporting DP to an analog serving system). 1.3 Alterna
