Global Intelligent Networking Services

The Global Intelligent Networking Services object is a child of the Call Services object.

The Global Intelligent Networking Services object specifies global configuration parameters that apply to all its child Global INS Trigger objects, and also displays summary alarm information for these child objects.

The Local Number Portability fields in this object allow you to specify caching of LNP data, to avoid the expense of repeated LNP lookups for the same number. Note that an LNP entry will never be cached for a subscriber who has the Force LNP lookup parameter set to True, because this indicates that the subscriber is in the process of being ported and the result of a LNP query may shortly change from one request to the next.


Depending on your service agreement with your LNP service provider, or on your SS7 interconnect agreement, caching of LNP entries may be prohibited. If you configure the NE to support LNP caching, it is your responsibility to ensure that you are not in breach of such agreements.



If you enable Local Number Portability caching, the additional resource requirement for the cache reduces the maximum number of subscribers that the NE can support. The cache can be tuned for the specific NE hardware on which it runs, in order to provide the optimum balance between cache performance (hit rate) and occupancy. The actual reduction in capacity depends on the size of the cache; as a rough guideline, 1 million cache entries take up the resources that would be required by 5000 subscribers. The default cache sizes are set to prioritize ultimate cache performance over subscriber capacity. You can tune the cache to reflect the number of subscribers on your switch using the statistics provided to monitor its actual size and performance. If you use the default LNP cache size, the number of subscribers that each NE type can support is reduced as follows:
  • CA9020: maximum subscribers reduced by 15,000 (from 200,000 to 185,000).
  • VP3510: maximum subscribers reduced by 5,000 (from 70,000 to 65,000).
  • VP2510: maximum subscribers reduced by 1,000 (from 20,000 to 19,000).
  • VP3500: maximum subscribers reduced by 1,000 (from 32,000 to 31,000).
If you enable CNAM caching (on the Global Caller ID Services object) as well as LNP caching, the reductions in capacity should be added together. For example, if you enable both CNAM and LNP caching on a CA9020 with the default cache sizes, the maximum number of subscribers is reduced by 65,000 (from 200,000 to 135,000).

Object-Specific Actions
Clear LNP cache This action is valid only when Trigger table for LNP lookup specifies an INS trigger. It removes all entries in the LNP cache. You are prompted to confirm or cancel this action.
Manage LNP cache This action is valid only when Trigger table for LNP lookup specifies an INS trigger. It creates an LNP Cache Entry child object in which you can check or delete an LNP cache entry.

Parameter

Access

Description
AIN response timer T1 duration Change Inactive This is the timer started when a TCAP query is sent to an SCP and stoppped when a response is received. Expiry of this timer results in the query being treated as having failed. This field is only used for ANSI variants. Range: 100 - 30000. The default is 3000.
Trigger table for LNP lookup Change The INS trigger to use for performing LNP lookup processing on this exchange. If no INS Trigger is specified, LNP lookup processing is disabled. You cannot activate this object unless this field is set to an active INS trigger with a trigger type of InfoAnalyzed and an application type of LNP lookup, or set to specify no INS trigger (which disables the LNP service). This field is ignored for non-ANSI variants. The default is no INS Trigger specified.
Local Number Portability - cache enabled Change Specifies whether Local Number Portability (LNP) information obtained from a network query should be cached to avoid the expense of repeated lookups. This field does not appear if Trigger table for LNP lookup is None. If you enable LNP caching, the additional resource requirement for the cache reduces the maximum number of subscribers that the NE can support. See the note above for further details. Values:
  • True
    Store LNP information obtained from network queries in a cache; check the cache when an LNP lookup is required, and use a network query only if no information is cached.
  • False (default)
    Do not cache LNP information; use a network query every time an LNP lookup is required.
Local Number Portability - maximum cache entries Change The maximum number of LNP entries that can be cached at any time. When this limit is reached, the least recently used entry will be discarded each time a new entry is cached. This field does not appear if Trigger table for LNP lookup is None. The range and default for this field depend on the NE type, as follows.
  • VP3510: Range 1 - 5,000,000, default 1,000,000
  • VP2510: Range 1 - 5,000,000, default 200,000
  • VP3500: Range 1 - 1,250,000, default 200,000
  • CA9020: Range 1 - 10,000,000, default 3,000,000
Local Number Portability - cache entry expiry time Change The maximum time for which a cache entry can be stored. When this limit is reached, the entry will be discarded. This field does not appear if Trigger table for LNP lookup is None. Range: 1 - 200 hours (a little over 8 days). The default is 48 hours (2 days).
Off-Hook Delay Subscriber Trigger - support Change Inactive Specifies whether the switch is currently configured to support the Off-Hook Delay Subscriber Trigger (used for AIN services that apply to particular subscribers). Values:
  • Configured
    The NE supports the service and subscribers can be configured to use it.
  • Not configured (default)
    The NE does not support the service.
  • Disabled
    The NE supports the service but it is currently suspended so that subscribers cannot use it.
If you select Configured or Disabled, you must specify a trigger in the Off-Hook Delay Subscriber Trigger - default trigger field.
Off-Hook Delay Subscriber Trigger - subscribed by default Change Inactive This field appears only if Off-Hook Delay Subscriber Trigger - support is Configured or Disabled. Specifies whether the Off-Hook Delay Subscriber Trigger is available to all subscribers by default. You can override this setting to allow or disallow the service for a particular subscriber. Values:
  • True
    All subscribers can use the service unless their subscriber configuration explicitly disallows it.
  • False (default)
    Subscribers cannot use the service unless their subscriber configuration explicitly allows it.
Off-Hook Delay Subscriber Trigger - default trigger Change Inactive This field appears only if Off-Hook Delay Subscriber Trigger - support is Configured or Disabled. The INS Trigger used by default as the Off-Hook Delay Subscriber Trigger for all subscribers. Select from the displayed list of INS Triggers that are configured to support Off-Hook Delay Subscriber service. You can override this setting for an individual subscriber if required. If you delete the trigger referenced by this field, the field shows Reference not valid and gives the index of the deleted trigger. Either change the field to specify another trigger, or add a new trigger with the specified index for use by this field.
Termination Attempt Trigger - support Change Inactive Specifies whether the switch is currently configured to support the Termination Attempt Trigger (used for AIN services that apply to particular subscribers). Values:
  • Configured
    The NE supports the service and subscribers can be configured to use it.
  • Not configured (default)
    The NE does not support the service.
  • Disabled
    The NE supports the service but it is currently suspended so that subscribers cannot use it.
If you select Configured or Disabled, you must specify a trigger in the Termination Attempt Trigger - default trigger field.
Termination Attempt Trigger - subscribed by default Change Inactive This field appears only if Termination Attempt Trigger - support is Configured or Disabled. Specifies whether the Termination Attempt Trigger is available to all subscribers by default. You can override this setting to allow or disallow the service for a particular subscriber. Values:
  • True
    All subscribers can use the service unless their subscriber configuration explicitly disallows it.
  • False (default)
    Subscribers cannot use the service unless their subscriber configuration explicitly allows it.
Termination Attempt Trigger - default trigger Change Inactive This field appears only if Termination Attempt Trigger - support is Configured or Disabled. The INS Trigger used by default as the Termination Attempt Trigger for all subscribers. Select from the displayed list of INS Triggers that are configured to support Termination Attempt service. You can override this setting for an individual subscriber if required. If you delete the trigger referenced by this field, the field shows Reference not valid and gives the index of the deleted trigger. Either change the field to specify another trigger, or add a new trigger with the specified index for use by this field.
