§ 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 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 § 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.
