23、events a called subscriber from receiving calls. When this feature is active, no incoming calls shall be offered to the subscriber. DND also blocks other alerting, such as the Call ForwardingUnconditional abbreviated (or reminder) alerting and Message Waiting Notification alerting. DND makes the sub
24、scriber inaccessible for call delivery. DND does not impact a subscribers ability to originate calls. DND has no impact upon held party recall alerting. Applicability to Telecommunications Services DND is applicable to voice telecommunication services. 1.1 Normal Procedures with Successful Outcome A
25、uthorization DND may be generally available or may be provided after prearrangement with the service provider. Deauthorization DND may be withdrawn at the subscribers request or for administrative reasons. Registration DND has no registration. Deregistration DND has no deregistration. Activation DND
26、 may be activated by an authorized subscriber specifying the DND feature code, as in: *FC + SEND . If the activation is accepted, the system shall indicate success with feature confirmation treatment.

If the deactivation is accepted, the system shall indica
28、te success with feature confirmation treatment. DND shall be deactivated upon deauthorization. Invocation The feature is invoked when there is an incoming call and DND is active. Normal Operation with Successful Outcome When DND is active, incoming calls for the subscriber shall be given refusal tre
29、atment. When DND is active, other alerting requests shall be blocked. Call Detail Record The system should record call detail information for the following: a. DND activation activities and events. b. DND deactivation activities and events. c. Incoming calls denied by DND. See DMH for the specific i
30、nformation to be included for each element. 1.2 Exception Procedures or Unsuccessful Outcome Registration None identified. Deregistration None identified.

36、nteraction between DND and CFNA is beyond the scope of this Standard. The following describes a possible implementation: DND interacts with CFNA. A call to a subscriber with both DND and CFNA active shall be given CFNA treatment immediately and not be given DND treatment. Call ForwardingUnconditiona
37、l (CFU) CFU takes precedence over DND. That is, calls arriving when CFU is active are forwarded unconditionally and not given refusal treatment. DND takes precedence over CFU abbreviated alert. That is, a call forwarded by CFU shall not notify the subscriber with an abbreviated (or reminder) alert.
38、Call Transfer (CT) None identified. Call Waiting (CW) DND takes precedence over CW. That is, calls arriving for a subscriber with DND and CW active shall be refused and not be given CW treatment. Calling Name Presentation (CNAP) None identified. Calling Name Restriction (CNAR) None identified. Calli
39、ng Number Identification Presentation (CNIP) DND takes precedence over CNIP.

41、gency Services (9-1-1) Emergency Services takes precedence over DND. That is, a call from an authorized emergency service bureau should be able to override a subscribers DND activation. Flexible Alerting (FA) Interaction between FA and DND is beyond the scope of this Standard. The following describe
42、s a possible implementation: DND affects FA. That is, if DND is active for a member, the member is considered to be inaccessible. Even if the subscriber has FA active, incoming calls to the FA Pilot Directory Number shall skip over the member or provide the applicable inaccessible treatment. Group 3
43、 Facsimile (G3 Fax) G3 Fax does not support DND. Message Waiting Notification (MWN) MWN MS indication, count, and pip tone takes precedence over DND. MWN indication and pip tone may still be applied while DND is active. DND takes precedence over MWN alert pip tone. That is, while DND is active, aler
44、ting shall not be applied. Mobile Access Hunting (MAH) Interaction between MAH and DND is beyond the scope of this Standard. The following describes a possible implementation: DND affects MAH. That is, if DND is active for a member, the member is considered to be inaccessible. Even if the subscriber

Password Call Acceptance (PCA) Interaction between PCA and DND is beyond the scope of this Standard. The following describes a possible implementation: DND takes precedence over PCA. That is, an incomin
48、g call to a subscriber with PCA and DND active is given DND treatment. Preferred Language (PL) None identified. Priority Access and Channel Assignment (PACA) DND takes precedence over PACA. That is, an incoming call to a subscriber with PACA invoked and DND active is given refusal treatment rather t
49、han the applicable busy treatment. Remote Feature Control (RFC) None identified. Selective Call Acceptance (SCA) Interaction between SCA and DND is beyond the scope of this Standard. The following describes a possible implementation: SCA takes precedence over DND. That is, incoming calls shall check for SCA first.
