The Local SCCP Access Point object is a child of the SCCP object.
The Local SCCP Access Point object defines the parameters for a local SCCP access point, which represents a subsystem that is using SCCP to communicate with other subsystems.

If your NE includes two or more Signaling Gateways with different point codes, you will normally configure an SCCP object for each Signaling Gateway, and a child Local SCCP Access Point for each Service Logic Host Route. The effect of this is that, when a TCAP query is launched to support a given service (for example, to request Automatic Callback), the SLHR will look for a Local SCCP Access Point under the SCCP that corresponds to the Signaling Gateway with which this call is associated. Assuming that such a Local SCCP Access Point is found, the TCAP query will be launched with the Originating Point Code (OPC) of this Signaling Gateway. This means that TCAP queries initiated for any given service may have different values of OPC, depending on the ISUP trunk on which the call arrived or the Signaling Gateway with which an originating subscriber is associated. This behaviour is consistent with the use of multiple point codes to emulate multiple separate switching systems. However, in some cases you may not want to initiate TCAP queries with different OPCs, for example because a provider of SCP-based services levies a charge for each different OPC from which TCAP queries may arrive. In this situation, you can define just one Local SCCP Access Point for a given service. The SLHR for this service will always use this Local SCCP Access Point, which means that all TCAP queries related to this service originate from the same OPC. |

A TCAP Service Logic Host Route (SLHR) can access any SCCP that has a Local SCCP Access Point object with an SSN ID matching the SLHR's SSN ID. To ensure that the configuration operates correctly when adding SCCP configuration, the Local SCCP Access Point should be the last child object you add to the SCCP (after creating all the other SCCP child objects). This ensures that an existing SLHR cannot attempt to access the SCCP while its configuration is incomplete. You cannot deactivate a Local SCCP Access Point while there are any active SLHRs that can access it (any active SLHRs that have the same SSN ID as the Local SCCP Access Point). |
Parameter |
Access |
Description |
SSN ID | Create | SSN value of this SCCP access point. All access points that are children of the same SCCP must have a unique SSN value. Range: 34 - 254. |
Local SCCP Access Point name | Change | A name to identify this Local SCCP Access Point. This must not match the name already used by any other Local SCCP Access Point. |
Remote Concerned Area | Change | The list of remote SCCPs to be informed of local and remote SCCP subsystem status change.
To configure a remote concerned area with members, you must:
|
Availability status | Read only | Availability status of the access point. Values:
|
Alarm state | Read only | Specifies whether any alarms are currently raised for this object. Values:
|
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 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. |
Diagnostics - logging - log level | Change | Specifies the level of logs recorded for this object. Logs with a priority equal to or greater than the priority specified are recorded. Set to Default level to use the system-wide default level. Values:
|
Diagnostics - API trace - enabled | Change | Specifies whether API tracing is enabled for this object. Values:
|
Diagnostics - API trace - trace tag | Change | An optional text string inserted into API tracing and PD logging for this object. (This string can include accented / international characters as defined in ISO 8859-1.) If you want to filter on this tag in the craft interface, do not include spaces or any of the characters ^ \ $ * + ? | ( ) , . ' ' " [ ] { }. |
Requested status | Read only | Specifies whether an administrator has attempted to activate the Local SCCP Access Point. Values:
|
Actual status | Read only | Specifies the current status of the Local SCCP Access Point. Values:
|
