Sec.  1.20007   Additional assistance capability requirements for wireline,
cellular, and PCS telecommunications carriers.

   (a) Definition—(1) 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.

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

   (3) 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.

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

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

   (6) 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).

   (7) 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.

   (8) 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.

   (9) J–STD–025. The standard, including the latest version, developed by the
   Telecommunications Industry Association (TIA) and the Alliance for
   Telecommunications Industry Solutions (ATIS) 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. Subsequently, TIA and ATIS published
   J–STD–025–A and J–STD–025–B.

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

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

   (12) 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.

   (13) 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).

   (14) 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.

   (b) In addition to the requirements in  Sec. 1.20006, wireline, cellular, and PCS
   telecommunications carriers shall provide to a LEA the assistance capability
   requirements regarding wire and electronic communications and call
   identifying information covered by J–STD–025 (current version), and, subject
   to the definitions in this section, may satisfy these requirements by
   complying with J–STD–025 (current version), or by another means of their own
   choosing. These carriers also shall provide to a LEA the following
   capabilities:

   (1) Content of subject-initiated conference calls;

   (2) Party hold, join, drop on conference calls;

   (3) Subject-initiated dialing and signaling information;

   (4) In-band and out-of-band signaling;

   (5) Timing information;

   (6) Dialed digit extraction, with a toggle feature that can
   activate/deactivate this capability.
