Call Content Channel

The Call Content Channel object defines information about the CCCs, including how you want the CCCs to be activated and deactivated. It is a child of the Warrant object.


CCCs are allocated separately. If there is not an available CCC at the time when it is requested, the request will simply be dropped. If you choose Separated delivery as your Call Content delivery method in the Warrant object, you will need at least two CCCs (one for each channel) and probably more (for example, in the case of three-way calls).



The EMS will prevent CCC(s) from being deleted in two cases.
  • If there are only two CCCs and you choose Separated delivery as your Call Content delivery method in the Warrant object
  • If there is only one CCC and you choose Combined delivery as your Call Content delivery method in the Warrant object.


Parameter

Access

Description
CCC ID Create The CCC ID is a unique ID for the Call Content Channel. It is agreed between the Telecom Service Provider (TSP) and the Law Enforcement Agency (LEA), and is specified on the warrant.
Deactivation mode Change The deactivation type required.
  • Normal (default)
    Deactivate normally, disconnect the CCC, and release any taps using this CCC in the quickest way that maintains internal consistency.
  • Quiesce
    Deactivate when all current intercepts have completed. Retain any current intercept being reported over this CCC, but prevent the setup of new intercepts using this CCC. Disconnect a permanently connected CCC when intercepts using it have completed.
  • Abort
    Deactivate as quickly as possible, disconnect the CCC, and release any taps using this CCC in the quickest way that maintains internal consistency.
LEA directory number Change inactive Specify the directory number of the destination of this CCC. This is the number, which the Law Enforcement Agency (LEA) has provided to receive the call content on, and is used to establish the CCC. It is also used to identify the CCC on CDC messages. This number must be a 10 digit national number .
Carrier ID Change inactive Specify the carrier ID (PIC2/PIC1) used for the connection to the CCC DN. This may be the local carrier code or the long distance carrier code, depending on the DN configured for the CCC. This field may be empty if a carrier ID is not required. Otherwise the length of this field must be 4 digits.
Connection type Change inactive This indicates whether the call content channel will be permanently established, ready to deliver call content, or whether it will only be established when an intercept subject begins a call for which call content should be delivered. Values:
  • Permanent
  • On demand
Max answer time Change inactive This field applies only if Connection type is On demand. Specify the length of time, in milliseconds, that the Law Enforcement Agency has to answer a call on this CCC before a tap is abandoned. This time starts from when an attempt is made to set up the CCC, and continues until the CCC is answered. Default: 10000 ms (10 seconds).
Bearer capability Change inactive Bearer capability (type of ISDN calls) for which this channel is to be used. Each channel can carry call content of only one type. This field is valid only if the subscriber's Call Agent signaling type is set to ISDN PRI. If Call Content delivery method in the Warrant object is set to Combined delivery, this field must be set to Speech or 3.1kHz audio, because data cannot be carried on a combined channel. Otherwise, you can set up separate channels for each type of call content that you want to collect. To collect data of either type (64kbps or 56kbps), you must set up at least two Call Content Channels with the same bearer capability, one for each direction of data flow. Values:
  • Speech or 3.1kHz audio
  • 64kbps data
  • 64kbps restricted
  • 56kbps data
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.
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 field was last reset to zero.
Requested status Read only Specifies whether an administrator has attempted to enable this object. Values:
  • Active
    The object has been activated.
  • Inactive
    The object has not been activated or has been deactivated.
Actual status Read only Specifies the current status of this object. Values:
  • Active
    The object has been activated.
  • Inactive
    The object has not been activated or has been deactivated.
