Sec.  22.1102   Definitions.

   Call identifying information. Call identifying information means dialing or
   signaling information that identifies the origin, direction, destination, or
   termination of each communication generated or received by a subscriber by
   means of any equipment, facility, or service of a telecommunications
   carrier. Call identifying information is “reasonably available” to a carrier
   if it is present at an intercept access point and can be made available
   without the carrier being unduly burdened with network modifications.

   Collection function. The location where lawfully authorized intercepted
   communications and call-identifying information is collected by a law
   enforcement agency (LEA).

   Content of subject-initiated conference calls. Capability that permits a LEA
   to monitor the content of conversations by all parties connected via a
   conference call when the facilities under surveillance maintain a circuit
   connection to the call.

   Destination. A party or place to which a call is being made (e.g., the
   called party).

   Dialed digit extraction. Capability that permits a LEA to receive on the
   call data channel digits dialed by a subject when a call is connected to
   another carrier's service for processing and routing.

   Direction. A party or place to which a call is re-directed or the party or
   place from which it came, either incoming or outgoing (e.g., a redirected-to
   party or redirected-from party).

   In-band and out-of-band signaling. Capability that permits a LEA to be
   informed when a network message that provides call identifying information
   (e.g., ringing, busy, call waiting signal, message light) is generated or
   sent by the IAP switch to a subject using the facilities under surveillance.
   Excludes signals generated by customer premises equipment when no network
   signal is generated.

   Intercept Access Point (IAP). Intercept access point is a point within a
   carrier's system where some of the communications or call-identifying
   information of an intercept subject's equipment, facilities, and services
   are accessed.

   J-STD-025. The interim standard developed by the Telecommunications Industry
   Association and the Alliance for Telecommunications Industry Solutions for
   wireline, cellular, and broadband PCS carriers. This standard defines
   services and features to support lawfully authorized electronic
   surveillance, and specifies interfaces necessary to deliver intercepted
   communications and call-identifying information to a LEA.

   LEA. Law enforcement agency; e.g., the Federal Bureau of Investigation or a
   local police department.

   Origin. A party initiating a call (e.g., a calling party), or a place from
   which a call is initiated.

   Party hold, join, drop on conference calls. Capability that permits a LEA to
   identify the parties to a conference call conversation at all times.

   Subject-initiated dialing and signaling information. Capability that permits
   a LEA to be informed when a subject using the facilities under surveillance
   uses services that provide call identifying information, such as call
   forwarding, call waiting, call hold, and three-way calling. Excludes signals
   generated by customer premises equipment when no network signal is
   generated.

   Termination. A party or place at the end of a communication path (e.g. the
   called or call-receiving party, or the switch of a party that has placed
   another party on hold).

   Timing information. Capability that permits a LEA to associate
   call-identifying information with the content of a call. A call-identifying
   message must be sent from the carrier's IAP to the LEA's Collection Function
   within eight seconds of receipt of that message by the IAP at least 95% of
   the time, and with the call event time-stamped to an accuracy of at least
   200 milliseconds.
