AMERICAN NATIONAL STANDARD Approval of an American National Standard requires review by ANSI that the requirements for due process, consensus, and other criteria for approval have been met by the standards developer. Consensus is established when, in the judgment of the ANSI Board of

Consensus requires that all views and objections be considered, and that a concerted effort be made tow

24、n;c. an action or operation by a user requires that a service be deactivated;d. an interaction with another supplementary service causes deactivation; that is, anotherservice takes precedence over an active service causing it to be deactivated.ANSI T1.610-19983If the network needs to activate or dea

25、ctivate a supplementary service and the Keypadprotocol applies to the served users interface, then the network may send an appropriatemessage (e.g., INFORMATION message) to the user that includes a Display text informationelement containing an appropriate indication that a supplementary service has

26、been activatedor deactivated. Networks supporting both the Keypad and the Feature key managementprotocols per access, in the network-to-user direction, may choose to send to the user aFeature indication information element in an INFORMATION message that identifies thefeature and whether it is being

27、activated or deactivated. Additional indications may beprovided to the user via the Display text information element in appropriate messages.5.2.3.3 Network initiated service activation or deactivationIt may be necessary for the network to either activate a supplementary service for a user, orto dea

28、ctivate a service that had been previously activated. See 4.5.2.4 for examples of whenthe network may need to activate or deactivate a service.If the network needs to activate or deactivate a supplementary service and the Feature keymanagement protocol applies to a served users interface, then the n

29、etwork shall send to theuser a Feature indication information element in an appropriate message (e.g.,INFORMATION message) that identifies the feature and whether it is being activated ordeactivated. Additional indications may be provided to the user via the Display textinformation element in approp

31、tes v and vi are not supported.12) The following shall be added to 6.2.2.1 at the end of the second paragraph (i.e.,immediately after the line “Active (U10), (N10)”):The Hold function is not applicable to call termination states other than the active state.13) Subclause 6.3.2.1 and its subclauses sh

32、all be replaced with the following text:For supplementary service procedures independent of an active call, the initiating side mustfirst establish a reliable data link connection between the network and the user according tothe data link services described in ANSI T1.602. Once the data link connect

33、ion is established,the user or the network starts the establishment of the signalling connection by transferring aREGISTER message across the usernetwork interface. This signalling connection isidentified by the call reference associated with the REGISTER message. The requestedsupplementary service

34、is identified by the operation value within the Facility informationelement. This signalling connection may be released by the exchange of return result, returnerror or reject component types contained in the Facility information element within aRELEASE COMPLETE message. Alternatively, the Networked

35、 Call Independent, ConnectionOriented procedures of Annex E may be used. The choice of signaling mechanisms isnetwork and application dependent.Examples of message exchange for supplementary service control for various scenarios isdescribed by means of arrow diagrams in Appendix I.To assign a call r

36、eference value and convey the supplementary service invocation, aREGISTER message with a Facility information element is used. The invoke operationcontained in the Facility information element present in the REGISTER message identifies thesupplementary service involved. One of the following will occ

37、ur:ANSI T1.610-199841) When the REGISTER message containing a Facility information element is sent andthe requested service is available, a FACILITY message containing the Facility informationelement may be returned. One or more exchanges of FACILITY messages maysubsequently occur. To terminate the

38、service interaction and release the call referencevalue, a RELEASE COMPLETE message is sent by either side of the interface. TheRELEASE COMPLETE message may also contain the Facility information element.2) If the content of the Facility information element is not understood, then a FACILITYmessage o

39、r a RELEASE COMPLETE message operation with the Facility informationelement is returned with the Reject component type. When the rejection has been returnedin a FACILITY message, the Facility information element can be resent in anotherFACILITY message or the call reference value released with a REL

40、EASE COMPLETEmessage.3) If the content of the Facility information element is understood, but the supplementaryservice request cannot be provided, then a FACILITY message or a RELEASE COMPLETEmessage with the Facility information element is returned with the component return error.When the rejection

41、 has been returned in a FACILITY message, the Facility informationelement can be resent in another FACILITY message or the call reference value releasedwith a RELEASE COMPLETE message.14) The following text shall be added as a new subclause 6.3.7:6.3.7 Invoke ID ReuseThe user or network may begin to

42、 reuse the invoke identifier value after a correlated responseis received or sent (either a Return result, Return error, or Reject component).If a response is not expected, the user or network may begin to reuse the invoke identifiervalue after sending the invoke component.If the operation is of the

43、 class “report failure only” or “report success only,” the operation willdefine when the invoke identifier can be reused.15) The following Note shall be added at the end of 6.3:NOTE Operation classes 2, 3, 4, and 5 as defined in CCITT Recommendation X.219 are valid for use inSupplementary Services d

44、efined in American National Standards.16) The following text shall be added to the end of the next-to-last paragraph of 6.3.6.3.If call clearing was initiated by the requester (e.g., the user), the recipient (e.g., the network)shall continue with the clearing procedures. If the call reference is rel

45、eased before a responsecan be sent, the requestor may not receive a response. In this case, ANSI SupplementaryService Standards will specify additional service-specific procedures.17) The following new paragraph shall be added after the next-to-last paragraph of 6.3.6.4.If a REGISTER message does no

46、t contain the Facility information element, the REGISTERmessage shall be discarded and a RELEASE COMPLETE message containing cause value#96, “mandatory information element is missing” shall be sent.ANSI T1.610-1998518) Replace Table 7-2 with the following (text addition is underlined):Message type:

The maximum length is network dependent and is either34 or 82 octets.4 Extended Facility information element may be used instead.19) Change the inclusion condition for the Facility information element in Table 7-6 to“Mandatory.” In addition, Note 4 shall be deleted.20) Add the following subclauses to the end of clause 7:7.2 Messages for Call Independent, Connection-Oriented SignallingThis clause defines the messages
