Global Intelligent Networking Services Trigger

The Global Intelligent Networking Services Trigger object is a child of the Global Intelligent Networking Services object. It contains information on how to handle an event that requires lookup by an SCP (for example, LNP or toll free numbers): the Service Logic Host Route used to access the SCP for this call, and the information that is included in the message sent to the SCP to identify the event requiring lookup.

When Number Validation determines that an SCP lookup is required to process a call of a particular type, it sets an attribute specifying a particular Global Intelligent Networking Services Trigger to use for the lookup.

When a subscriber who has Off-Hook Delay Subscriber Service attempts to make a call, or when a call arrives for a subscriber who has Termination Attempt Service, the subscriber's Intelligent Networking Services configuration determines the Intelligent Networking Services Trigger to use for the lookup.


Parameter

Access

Description
Trigger index Create This field is optional, and in most cases you do not need to specify it; the index will be assigned automatically. However, if you are adding a new trigger to replace one that has been deleted, specify the index of the deleted trigger. This ensures that references to it in other EMS objects will continue to be valid.
Trigger name Change A mandatory user-friendly name identifying the INS Trigger. Specify a name of up to 64 characters.
Trigger type Change Inactive The type of detection point to which the trigger entry applies. Values:
  • None
    This entry is used to handle unsolicited messages from an external Intelligent Networking component (such as an SCP), rather than to handle internal triggers.
  • InfoAnalyzed
    This entry relates to an event detected after number validation has been completed.
  • InfoCollected
    This entry relates to an event detected after the dialed digits have been collected but before number validation.
  • TerminationAttempt
    This entry is used to handle AIN services for calls terminating at a subscriber on the switch.
Associated service Change Inactive / Read only The service associated with this trigger entry. The valid values depend on the setting of the Trigger type field. If the Trigger type field is set to InfoAnalyzed, select from the following values:
  • LNP lookup
  • AIN toll free lookup
  • Generic Specific Digit String service
If you are using AIN toll free lookup, you will need to check with your SCP service provider which AIN announcements are required, and customize the NE to support these announcements. See the Integration and Customization Manual for more details. If the Trigger type field is set to InfoCollected, select from the following values:
  • Off-Hook Delay Routing service
  • Off-Hook Delay Subscriber service
If the Trigger type field is set to TerminationAttempt, this field is read only and set to Termination Attempt service. If the Trigger type field is set to None, this field is read only and set to AIN unsolicited messages.
Service Logic Host Route Change Inactive The Service Logic Host Route used by this trigger. Select from the displayed list of Service Logic Host Routes for which Outgoing query routes is set to All routes permitted or Specified routes only. The Service Logic Host Route must be active before you can activate the INS Trigger. It specifies common routing information for the applications using the Intelligent Networking Services object.
Reroute action Change Inactive Specifies whether to perform a subset of Number Validation (using the E.164 tables), to modify routing attributes based on a new number that may have been returned. This applies only if the SCP lookup results in a "reroute call" TCAP response. Values:
  • Skip number validation
    Do not perform any additional number validation after the response from the SCP lookup.
  • Do number validation for routing
    Perform a subset of Number Validation (using the E.164 tables) after the response from the SCP lookup.
  • For more details of the attributes that are maintained across the SCP lookup, see Operations Manual: Routing. If the call is a long-distance call in Canada that requires an ISUP called address prefix, or if you need to set any user-defined routing attributes (including the MF user defined call type) for this call, you should use the value Do number validation for routing to ensure that the routing attributes are set correctly if the SCP lookup returns a new number.
Alarm state Read only Specifies whether any alarms are currently raised for this object. Values:
  • Clear
    No alarms are currently raised.
  • Attention Required
    Attention Required - the object is not operating normally, and needs operator intervention.
  • Attend To Dependent
    Attention Required elsewhere - another object on which this object depends is not operating normally.
Alarm log correlator - Attention Required Read only Identifier of the log message for the event that caused the last Attention Required alarm state for this object. This field is reset when Attention Required alarm events is reset to zero.
Attention Required alarm events Read only / Reset Number of times (since the alarm count was reset) that this object's alarm state has gone to Attention Required.
Alarm log correlator - Attend To Dependent Read only Identifier of the log message for the event that caused the last Attend To Dependent alarm state for this object. This field is reset when the Attend To Dependent alarm events field is reset to zero.
Attend To Dependent alarm events Read only / Reset Number of times (since this field was reset) that this object's alarm state has gone to Attend To Dependent.
Alarm state changed timestamp Read only The time at which the Alarm state last changed.
Alarm events reset timestamp Read only The time at which the Attention Required alarm events was last reset to zero.
Requested status Read only Specifies whether an administrator has attempted to activate the Global Intelligent Networking Services Trigger. Values:
  • Active
    The object has been activated.
  • Inactive
    The object has not been activated or has been deactivated.
  • Disabled
    The object has been disabled.
Actual status Read only Specifies the current status of the Global Intelligent Networking Services Trigger. Values:
  • Active
    The object is active.
  • Activating
    Activation is in progress.
  • Deactivating
    Deactivation is in progress.
  • Inactive
    The object is inactive.
  • Disabled
    The object has been disabled.
  • Activation Failed
    The object is inactive because an activation attempt has failed.
  • Failed
    The object was active but has failed.
  • Quiescing
    The object is preparing for normal deactivation. It is operating normally but will not accept any new users.
  • Waiting For Parent
    The object cannot be used because its parent object is not yet active.
  • Parent Failed
    The object cannot be used because its parent object has failed.
