Each Signaling Link object is a child of a Signaling Linkset object.
The Signaling Link object contains information about a link to an adjacent signaling point. There can be up to 16 links to each adjacent signaling point and there is a Signaling Link object for each link. You must create at least one signaling link for each signaling linkset. Additional signaling links may be created at a later stage to increase the capacity of a linkset to an adjacent signaling point.
If the parent Signaling Linkset represents a connection to an internal destination (another Signaling Gateway on the same NE), it can include only a single Signaling Link, which is an internal link representing the internal connection to the destination.
For initial configuration, set the following parameters:
Object-Specific Actions | |
Inhibit | To stop allowing traffic to use this link (for example in preparation for maintenance work on the link), click on the Inhibit pushbutton. The Last action status field shows the results of the action. This pushbutton is grayed for an internal link, or if the link is already inhibited or is disabled. Note that you cannot inhibit all links in a Signaling Linkset at the same time. |
Uninhibit | To allow traffic to use an inhibited link again, click on the Uninhibit pushbutton. The Last action status field shows the results of the action. This pushbutton is grayed for an internal link, or if the link is not already inhibited or is disabled. |

Access |
Description |
Signaling link code | Create | This field does not appear for a link to an internal destination. Unique index identifying the link within the linkset. This value must be the same at both ends of the link. Range: 0 - 15. |
Link name | Change | Unique user-friendly name identifying the link. Specify a name of up to 30 characters. If a name is not specified, the EMS displays only the signaling link code. |
Timer Profile | Change | This field does not appear for a link to an internal destination. Signaling Link Timer Profile to associate with the link. Select from the displayed list of profiles. This field defaults to the default Signaling Link Timer Profile. |
Signaling Cross Connect | Change Inactive | This field does not appear for a link to an internal destination. The Signaling Cross Connect used by this link. Click on the button to select the Media Gateway that owns the Cross Connect, and then to select from a list of Cross Connects on the selected Media Gateway. The EMS then updates the values of the IP Address and M2UA identifier fields. |
IP address | Read only | This field does not appear for a link to an internal destination. The IP address of the Media Gateway that owns the Signaling Cross Connect used by this link. |
M2UA identifier | Read only | This field does not appear for a link to an internal destination. The M2UA identifier of the Signaling Cross Connect used by this link. |
Link status | Read only | Specifies the current SS7 functional status of the link, as described in Recommendation Q.704. This is set to one or more of the following values:
|
Current congestion level | Read only | Specifies whether the link is currently congested. Range: 0 - 3. A value of zero indicates no congestion. |
Last action status | Read only | The status of the last Inhibit, Uninhibit, or Test action attempted on this link. Values:
|
Last action time | Read only | The time at which the last Inhibit, Uninhibit, or Test action was attempted on this link. |
Alarm state | Read only | Specifies whether any alarms are currently raised for this object. Values:
|
Alarm log correlator | 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 the Attention Required alarm events field 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 diagnostics tag inserted into API tracing and PD logging for this object. This tag may include any ASCII characters. However, 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 Signaling Link. Values:
|
Actual status | Read only | Specifies the current status of the Signaling Link. Values:
