23、52 53 54 55 56 57 58 59 60 519-1 Selective Call Acceptance (SCA) 1 Selective Call Acceptance (SCA) Selective Call Acceptance (SCA) is a call screening service that allows a subscriber to receive incoming calls only from parties whose Calling Party Numbers (CPNs) are in an SCA screening list of speci
24、fied CPNs. Calls from CPNs not on the SCA screening list and calls without a CPN shall be given call refusal treatment while SCA is active. The SCA screening list is a set of CPNs that shall be permitted to terminate to the called subscriber. The Originating Switch provides the Calling Party Number
25、(CPN). A subscriber may select a diversion number termination address when the subscriber registers the SCA. SCA does not impact a subscribers ability to originate calls. Applicability to Telecommunications Services SCA is applicable to voice telecommunication services. 1.1 Normal Procedures with Su
26、ccessful Outcome Authorization SCA may be generally available or may be provided after prearrangement with the service provider. The SCA authorization may have the following subscription options: Table 1: SCA Subscription Options Subscription Options Values Diversion Registration Variable. Subscribe
27、r is authorized to specify his or her own diversion number or refusal treatment. Fixed. The diversion number or refusal treatment is registered upon authorization. Number Registration Variable. Subscriber is authorized to add and delete addresses to be screened. Fixed. Screened addresses are registe
28、red upon authorization. Activation Demand. The subscriber is authorized to control the activation and deactivation of SCA. Permanent. SCA is activated while authorized.

Registration SCA Diversion Number Registration The SCA diversion number shall be registered upon authorization fo
30、r Fixed Diversion Registration subscribers. The SCA diversion number may be registered upon authorization for Variable Diversion Registration subscribers. To register the diversion forward-to number for diverting the refused calls, a Variable Diversion Registration authorized subscriber enters the S
31、CA diversion registration feature code and a diversion number termination address or voice message system Modifier Digit 8 (“V” on the keypad), as in: *FC + termination address + SEND , or *FC + 8 + SEND (Voice message system). If the registration is accepted, the system shall indicate success with
32、feature confirmation treatment. Diversion number registration associates the subscriber with the termination address as a diversion number or with a particular voice mailbox on a voice message system. Voice mailbox passwords are registered separately with the voice message system. The system should
33、not accept diversion numbers to the operator (0- or 0+), service codes (N11), police, fire or similar agencies, or a revertive call. SCA Specified Screening Number Registration The SCA screening list numbers shall be registered upon authorization for Fixed Number Registration subscribers. The SCA sc
34、reening list numbers may be registered upon authorization for Variable Number Registration subscribers. To register a number or add a number to the screening list, a Variable Number Registration authorized subscriber enters the SCA number registration feature code and a termination address, as in: *
35、FC + termination address + SEND . If the registration is accepted, the system shall indicate success with feature confirmation treatment. SCA “Last Calling Party” Screening Number Registration To register the calling party number of the last incoming call (including calling party numbers restricted
36、from presentation) to the screening list, a Variable Number TIA-664.519-B 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 519-3 Selective Call Acceptance (SCA) Registration auth
37、orized subscriber enters the SCA registration feature code and the “last calling party” Modifier Digit “9,” as in: *FC + 9 + SEND . If the registration is accepted, the system shall indicate success with feature confirmation treatment. Deregistration SCA diversion number and screening list numbers s
38、hall be deregistered upon deauthorization. SCA Diversion Number Deregistration To deregister the diversion forward-to number for diverting refused calls, a Variable Diversion Registration authorized subscriber enters the SCA variable diversion deregistration feature code, as in: *FC0 + SEND . If the
39、 deregistration is accepted, the system shall indicate success with feature confirmation treatment. SCA Specified Screening Number Deregistration To deregister a number or delete a particular number from the screening list, a Variable Number Registration authorized subscriber enters the SCA deregist
40、ration feature code and the calling party number to be affected, as in: *FC0 + termination address + SEND . If the deregistration is accepted, the system shall indicate success with feature confirmation treatment. SCA All “Last Calling Party” Screening Numbers Deregistration To deregister all number
41、s entered as the “last calling party” from the screening list, a Variable Number Registration authorized subscriber enters the SCA deregistration feature code and the “last calling party” Modifier Digit “9,” as in: *FC0 + 9 + SEND . If the deregistration is accepted, the system shall indicate succes
42、s with feature confirmation treatment. SCA All Screening Numbers Deregistration To deregister all numbers from the screening list, a Variable Number Registration authorized subscriber enters the SCA deregistration feature code and the Modifier Digits “99,” as in: *FC0 + 99 + SEND . If the deregistra
43、tion is accepted, the system shall indicate success with feature confirmation treatment. TIA-664.519-B 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 Selective Call Acceptance
44、(SCA) 519-4 Activation SCA shall be activated upon registration for Permanent Activation subscribers. SCA may be activated upon registration of a diversion number and one or more screening numbers. SCA may also be activated when a Demand Activation subscriber enters the SCA activation feature code,
45、as in: *FC + SEND . If the activation is accepted, the system shall indicate success with feature confirmation treatment. Deactivation SCA shall be deactivated upon deauthorization or deregistration of all SCA screening numbers. SCA may be deactivated when a Demand Activation subscriber enters the S
46、CA deactivation feature code; as in: *FC0 + SEND . If the deactivation is accepted, the system shall indicate success with feature confirmation treatment. Invocation When SCA is active, SCA is invoked for incoming calls, including calls arriving through the Roamer Port. Normal Operation with Success
47、ful Outcome When SCA is invoked, the CPN of the incoming call is checked against the SCA screening list. If there is a match, the call is allowed to proceed through call termination treatment as applicable for other subscribed features. If there is not a match or the CPN is not available, the call i
48、s refused (i.e., an appropriate treatment as authorized at time of subscription may be given to the calling party). Incoming calls refused by SCA screening shall be treated independent of the subscribers status (“idle” or “busy”). If an SCA diversion number is registered, the call shall be diverted
49、to the specified forward-to number or to the associated voice mailbox as indicated. Otherwise the refused call shall be given the default system refusal treatment. Call Detail Record The system should record call detail information for the following: a. SCA registration activities and events.
