The Warrant object is a child of the Lawful Interception object. It defines information about the warrant, how the warrant is to be implemented and how the information collected by the MetaSwitch NE will be sent to the LEA.
Parameter |
Access |
Description |
Warrant ID | Index | The number of the warrant. This field uniquely identifies a warrant on this MetaSwitch NE. |
Deactivation mode | Change | The deactivation type required. Values:
|
Case ID | Change inactive | Specify the case identity assigned by the LEA for the particular electronic surveillance described by this warrant. The contents of this field are used as an ID on CDC messages. |
Start time required | Change inactive | This field specifies whether a start time is configured for this warrant. Values:
|
Start time | Change inactive | Specify the date and time at which this warrant becomes operational. Note that the time used is the local time of the Call Agent or Integrated Softswitch. If End time is specified, the start time must be earlier than the end time. This field is mandatory if Start time required is set to True. |
End time required | Change | This field specifies whether an end time is configured for this warrant. This field can be changed while the warrant is active, in order to extend a warrant that is about to time out. Values:
|
End time | Change | Specify the date and time at which this warrant will expire. Note that the time used is the local time of the Call Agent or Integrated Softswitch. If Start time has been specified, the end time must be later than the start time. This field is mandatory if End time Required is set to True. This field can be changed while the warrant is active, in order to extend a warrant that is about to time out. |
Call content delivery | Change inactive | This identifies whether the voice content of calls covered by this warrant is delivered to the LEA on a Call Content Channel (CCC). Values:
|
Call content delivery method | Change inactive | This indicates whether the call content channels will carry separated call content (for example, unidirectional call content), or whether they will contain combined call content. It is ignored if call content is not being delivered.
Note that if Combined call content is specified, increased DSP mixpoint resource is required on the switch, thus reducing your overall available resource for services such as three-way calling. Also, Combined call content cannot be used for intercepting ISDN data calls. If any child Call Content Channel is configured with Bearer capability set to a value other than Speech or 3.1kHz audio, the call content delivery method must be Separated.
If Separated call content is specified, then at least two CCCs are required in order to receive the content from both ends of the call. Values:
|
Call content channel billing type | Change inactive | Specify the billing method that will be used to bill the LEA for the call interception. Values:
|
Call content channel billing number | Change inactive | Specify the number to be used in a Call Detail Record (CDR) for the usage measurements associated with the call content channels for this warrant. This is used as an added security feature, so that in information sent to the Law Enforcement Agency (LEA), no Intercept Subject's number needs to be shown. For all calls intercepted by this warrant, whatever the Intercept Subject, this dummy number will be used. It is ignored if call content is not being delivered. For billing CDR purposes, this number should be a 10 digit national number . |
CDC surveillance level | Change inactive | This identifies the level of call identifying information to be provided on the intercepts for the subscribers covered on this warrant. Values:
|
CDC collection function IP address | Change inactive | Specify the IP address of the destination of the CDC. This is the IP address, which the Law Enforcement Agency (LEA) has provided to receive the call data channel on. Currently only IPv4 addresses in dotted-decimal format are supported. |
CDC collection function IP port | Change inactive | Specify the TCP port number for the CDC destination (the port the call data channel will be connected to on the above IP address). This is specified by the LEA. |
LEA name | Change inactive | Specify the Law Enforcement Agency (LEA) that owns this warrant. |
LEA extra info | Change inactive | Specify any extra information about the Law Enforcement Agency (LEA) that owns this warrant. For example, this field could contain a mailing address for the LEA. |
Alarm state | Read only | Specifies whether any alarms are currently raised for this object. Values:
|
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 (UTC) at which the Alarm state last changed. |
Alarm events reset timestamp | Read only | The time (UTC) at which the Attention Required alarm events was last reset to zero. |
Child CCC Attention Required alarms | Read only | The number of CCCs with Alarm State currently set to Attention Required. |
Child CCC Attention Required alarm events | Read only | The total number of times that the Alarm State on a CCC on this Warrant has gone to Attention Required. |
Summary child alarm state | Read only | Summarizes the alarm status for all children of this object. Values:
|
Requested status | Read only | Specifies whether an administrator has attempted to enable this object. Values:
|
Actual status | Read only | Specifies the current status of this object. Values:
|
