    I. Background
    
        On October 25, 1994, the President signed into law the 
    Communications Assistance for Law Enforcement Act (CALEA) (Public Law 
    103-414; 47 U.S.C. 1001-1010). This law presents law enforcement's 
    requirements for the surveillance of wire or electronic communications. 
    The primary purpose of the CALEA is to clarify a telecommunications 
    carrier's duty to assist law enforcement agencies with the lawful 
    interception of communications and the acquisition of call-identifying 
    information in an ever-changing telecommunications environment. To 
    ensure that law enforcement agencies can continue to conduct authorized 
    surveillance of wire or electronic communications, the CALEA states 
    that telecommunications carriers must meet the assistance capability 
    requirements set forth in section 103 of the Act (and restated in 
    Appendix A of this notice).
        Section 104 of the CALEA mandates that the Attorney General of the 
    United States provide notice of estimates for the actual and maximum 
    number of pen register, trap and trace, and communication intercepts 
    that law enforcement agencies may conduct and use simultaneously.
        The definitions for ``actual capacity'' and ``maximum capacity'' 
    are included below:
        Actual Capacity--``notice of the actual number of communication 
    interceptions. pen registers, and trap and trace devices, representing 
    a portion of the maximum capacity that the Attorney General estimates 
    that government agencies authorized to conduct electronic surveillance 
    may conduct and use simultaneously by the date that is 4 years after 
    the date of enactment of the CALEA'' (CALEA, section 104(a)(1)(A)).
        Maximum Capacity--``notice of the maximum capacity required to 
    accommodate all of the communication interceptions, pen registers, and 
    trap and trace devices that the Attorney General estimates that 
    government agencies authorized to conduct electronic surveillance may 
    conduct and use simultaneously after the date that is 
    
    [[Page 53644]]
    4 years after of enactment of the CALEA'' (CALEA, section 
    104(a)(1)(B)).
        This Federal Register announcement serves as the initial notice of 
    the government's actual and maximum capacity requirements. These 
    requirements will aid telecommunications carriers in developing and 
    deploying solutions to meet the assistance capability requirements set 
    forth in section 103 of the CALEA. A final notice will be issued in 
    accordance with the CALEA requirements after considering comments to 
    this initial notice.
        The actual and maximum capacity requirements were developed by the 
    FBI in coordination with law enforcement. By order of the Attorney 
    General of the United States, as codified in 28 CFR 0.85 (o), 
    government implementation responsibilities under the CALEA were 
    delegated to the FBI. The FBI, in turn, is establishing TILU to carry 
    out the government's implementation responsibilities, including the 
    publication of capacity notices.
        For the purposes of this document, the terms defined in section 
    2510 of title 18, United States Code, and section 102 of the CALEA 
    (section 1001 of title 47, United States Code) have, respectively, the 
    meanings stated in those sections. Additional clarification of terms is 
    provided in Appendix B of this notice.
    
    II. Introduction
    
        The capacity figures in this notice reflect the combined number of 
    simultaneous pen register, trap and trace, and communication 
    interceptions that law enforcement may conduct by October 25, 1998. All 
    telecommunications carriers must, within 3 years after the publication 
    of the final notice of capacity requirements or within 4 years after 
    the date of enactment of the CALEA, whichever is longer, ensure that 
    their systems are capable of accommodating simultaneously the number of 
    pen register, trap and trace, and communication interceptions 
    identified in the actual capacity requirements. Furthermore, all 
    telecommunications carriers shall ensure capabilities exist to 
    expeditiously accommodate any increase in the actual number of pen 
    register, trap and trace, and communication interceptions that 
    authorized agencies may seek to conduct and use, up to the maximum 
    capacity requirement. Some carriers may not need to make modifications 
    to their equipment, facilities, and services in response to this notice 
    because they currently meet all law enforcement capacity and capability 
    requirements for electronic surveillance.
        The capacity requirements are not intended to specify, required or 
    prohibit adoption of any particular system design or configuration by a 
    telecommunications carrier, equipment manufacturer, or support services 
    provider. These entities must develop an appropriate solution to comply 
    with the capacity requirements set forth in this notice and with the 
    assistance capability requirements found in section 103 of the CALEA. 
    In developing solutions, carriers should consider the effect that 
    particular services and features may have on capacity requirements. For 
    example, the required number of ports, lines, or other network 
    resources may vary depending upon the use of particular services and 
    features by an intercept subject. The FBI, along with other law 
    enforcement agencies, will be available, through the consultative 
    process, to discuss these engineering issues.
        In accordance with the intent of the CALEA, carriers must ensure 
    that their equipment, facilities, or services that provide a customer 
    or subscriber with the ability to originate, terminate, or direct 
    communications are capable of meeting the capability and capacity 
    requirements mandated by the CALEA. These requirements apply to 
    existing and future telecommunications carriers.
    
    III. Capacity Requirements Derivation
    
        The capacity figures that are presented in this initial notice were 
    derived as a result of a thorough analysis of electronic surveillance 
    needs. Information regarding electronic surveillance activities for a 
    specific time period was obtained from telecommunications carriers, law 
    enforcement, U.S. District Courts, State Courts, State Attorneys 
    General, and State District Attorneys to establish a historical 
    baseline of activity.
        The historical baseline of electronic surveillance activity was 
    determined after examination of both the location and occurrence of 
    each electronic surveillance reported. The historical baseline was then 
    analyzed to derive the total and simultaneous electronic surveillance 
    activity by switch and within specific geographic areas. Future 
    capacity needs were then determined after consideration of the impact 
    of demographics, market trends, and other factors on the historical 
    baseline.
        The analysis indicates that electronic surveillance activity varies 
    by geographic area. Therefore, the capacity requirements will vary by 
    geographic area. The capacity requirements are reported by category, 
    with each geographic area being assigned to one of three distinct 
    categories. The use of categories enables capacity requirements to be 
    stated in a manner that reasonably represents law enforcement 
    electronic surveillance needs in all geographic areas, yet does not 
    overburden the telecommunications industry by holding all carriers to 
    the same level of capacity.
        Category I (the highest category) and Category II (the intermediate 
    category) represent those geographic areas where the majority of 
    electronic surveillance activity occurs. Only a few of the most densely 
    populated areas, which have historically been areas of high electronic 
    surveillance activity, are grouped into Category I. Other densely 
    populated areas and some suburban areas, with moderate electronic 
    surveillance activity, are grouped into Category II. The numbers for 
    these categories were derived based on the analysis described above. 
    Category I and Category II apply to approximately 25 percent of the 
    equipment, facilities, and services covered by the survey over the time 
    period.
        Category III (the lowest category) represents law enforcement's 
    minimum acceptable capacity requirements for electronic surveillance 
    activity. This category covers all other geographic areas. The numbers 
    for Category III were derived by analyzing areas of historically low 
    electronic surveillance activity and projecting future needs in order 
    to establish a requirement for a minimum level of capacity for 
    electronic surveillance.
        All telecommunications carriers are expected to meet the minimum 
    capacity requirements of Category III. Carriers will be individually 
    notified of those specific geographic areas within the areas they serve 
    that exceed Category III and warrant a Category I or Category II 
    capacity requirement. The individual carrier notifications will occur 
    contemporaneously with the publication of the final notice. It is 
    anticipated that the majority of the area served by a carrier will fall 
    into Category III; however, if Category I and Category II capacity 
    requirements are necessary, they are likely to affect only a small 
    portion of their area served.
        This initial capacity notice includes the actual and maximum 
    capacity requirements for Categories I, II, and III. After considering 
    comments to this initial notice, a final notice will be published. 
    Future changes to the maximum capacity requirements issued in the final 
    notice will be published in the Federal Register, as necessary, in 
    accordance with section 104(c). 
    
    [[Page 53645]]
    
    
    IV. Initial Statement of Actual and Maximum Capacity
    
        The actual and maximum capacity requirements are presented as a 
    percentage of the engineered capacity of the equipment, facilities, and 
    services that provide a customer or subscriber with the ability to 
    originate, terminate, or direct communications. Engineered capacity 
    refers to the maximum number of subscribers that can be served by that 
    equipment, facility, or service. Frequently, the percentage is applied 
    to the engineered subscriber capacity of a switch, however, the 
    percentage can also apply to nonswitch equipment (i.e., network 
    peripherals) involved in the origination, termination, or direction of 
    communications. Percentages are being used rather than fixed numbers 
    due to the dynamics and diversity of the telecommunications industry. 
    The use of percentages allows telecommunications carriers the 
    flexibility to adjust to changes in marketplace conditions or changes 
    in the number of subscribers, access lines, equipment, facilities, 
    etc., and still know the required level of capacity.
        As a result of extensive consultation with federal, State, and 
    local law enforcement agencies, telecommunications carriers, providers 
    of telecommunications support services, and manufacturers of 
    telecommunications equipment, the FBI proposes the following capacity 
    requirements for Categories I, II, and III:
    
    Category I
    
    Actual Capacity
        Each telecommunications carrier must provide the ability to meet 
    the capability assistance requirements defined in section 103 of the 
    CALEA for a number of simultaneous pen register, trap and trace, and 
    communication interceptions equal to 0.5% of the engineered capacity of 
    the equipment, facilities, or services that provide a customer or 
    subscriber with the ability to originate, terminate, or direct 
    communications.
    Maximum Capacity
        Each telecommunications carrier must ensure that it can 
    expeditiously increase its capacity to meet the assistance capability 
    requirements defined in section 103 of the CALEA for a number of 
    simultaneous pen register, trap and trace, and communication 
    interceptions equal to 1% of the engineered capacity of the equipment, 
    facilities, or services that provide a customer or subscriber with the 
    ability to originate, terminate, or direct communications.
    
    Category II
    
    Actual Capacity
        Each telecommunications carrier must provide the ability to meet 
    the capability assistance requirements defined in section 103 of the 
    CALEA for a number of simultaneous pen register, trap and trace, and 
    communication interceptions equal to 0.25% of the engineered capacity 
    of the equipment, facilities, or services that provide a customer or 
    subscriber with the ability to originate, terminate, or direct 
    communications.
    Maximum Capacity
        Each telecommunications carrier must ensure that it can 
    expeditiously increase its capacity to meet the assistance capacity 
    requirements defined in section 103 of the CALEA for a number of 
    simultaneous pen register, trap and trace, and communication 
    interceptions equal to 0.5% of the engineered capacity of the 
    equipment, facilities, or services that provide a customer or 
    subscriber with the ability to originate, terminate, or direct 
    communications.
    
    Category III
    
    Actual Capacity
        Each telecommunications carrier must provide the ability to meet 
    the capability assistance requirements defined in section 103 of the 
    CALEA for a number of simultaneous pen register, trap and trace, and 
    communication interceptions equal to 0.05% of the engineered capacity 
    of the equipment, facilities, or services that provide a customer or 
    subscriber with the ability to originate, terminate, or direct 
    communications.
    Maximum Capacity
        Each telecommunications carrier must ensure that it can 
    expeditiously increase its capacity to meet the assistance capability 
    requirements defined in section 103 of the CALEA for a number of 
    simultaneous pen register, trap and trace, and communication 
    interceptions equal to 0.25% of the engineered capacity of the 
    equipment, facilities, or services that provide a customer or 
    subscriber with the ability to originate, terminate, or direct 
    communications.
        When translated from percentages to numbers, capacity requirements 
    should be rounded up to the nearest whole number.
    
    V. Carrier Statements and Consultation
    
        As set forth in section 104(d) of the CALEA, each 
    telecommunications carrier is required to provide within 180 days after 
    publication of the final capacity notice a statement identifying any of 
    its systems or services that do not have the capacity to meet the 
    assistance capability requirements stated in section 103 of the CALEA. 
    These carrier statements will be used in conjunction with law 
    enforcement priorities and other factors to determine the specific 
    equipment, facilities, and services that require immediate modification 
    and that may be eligible for cost reimbursement. The FBI will consult 
    with telecommunications carriers to establish a template for responding 
    to the capability and capacity requirements.

    Assistance Capability Requirements
    
        (a) Capability Requirements.--Except as provided in subsections 
    (b), (c), and (d) of this section and sections 108(a) and 109(b) and 
    (d), a telecommunications carrier shall ensure that its equipment, 
    facilities, or services that provide a customer or subscriber with 
    the ability to originate, terminate, or direct communications are 
    capable of--
        (1) expeditiously isolating and enabling the government, 
    pursuant to a court order or other lawful authorization, to 
    intercept, to the exclusion of any other communications, all wire 
    and electronic communications carried by the carrier within a 
    service area to or from equipment, facilities, or services of a 
    subscriber of such carrier concurrently with their transmission to 
    or from the subscriber's equipment, facility, or service, or at such 
    later time as may be acceptable to the government;
        (2) expeditiously isolating and enabling the government, 
    pursuant to a court order or other lawful authorization, to access 
    call-identifying information that is reasonably available to the 
    carrier--
        (A) before, during, or immediately after the transmission of a 
    wire or electronic communication (or at such later time as may be 
    acceptable to the government); and
        (B) in a manner that allows it to be associated with the 
    communication to which it pertains, except that, with regard to 
    information acquired solely pursuant to the authority for pen 
    registers and trap and trace devices (as defined in section 3127 of 
    title 18, United States Code), such call-identifying information 
    shall not include any information that may disclose the physical 
    location of the subscriber (except to the extent that the location 
    may be determined from the telephone number);
        (3) delivering intercepted communications and call-identifying 
    information to the government, pursuant to a court order or other 
    lawful authorization, in a format such that they may be transmitted 
    by means of equipment, facilities, or services procured by the 
    government to a location other than the premises of the carrier; and
        (4) facilitating authorized communications interceptions and 
    access to call-identifying information unobtrusively and with a 
    minimum of interference with any subscriber's telecommunications 
    service and in a manner that protects--
    
    [[Page 53646]]
    
        (A) the privacy and security of communications and call-
    identifying information not authorized to be intercepted; and
        (B) information regarding the government's interception of 
    communications and access to call-identifying information.
        (b) Limitations.--
        (1) Design of Features and Systems Configurations.--This title 
    does not authorize any law enforcement agency or officer--
        (A) to require any specific design of equipment, facilities, 
    services, features, or system configurations to be adopted by any 
    provide of a wire or electronic communication service, any 
    manufacturer of telecommunications equipment, or any provider of 
    telecommunications support services; or
        (B) to prohibit the adoption of any equipment, facility, 
    service, or feature by any provider of a wire or electronic 
    communication service, any manufacturer of telecommunications 
    equipment, or any provider of telecommunications support services.
        (2) Information Services; Private Networks and Interconnection 
    Services and Facilities.--The requirements of subsection (a) do not 
    apply to--
        (A) information services; or
        (B) equipment, facilities, or services that support the 
    transport or switching of communications for private networks or for 
    the sole purpose of interconnecting telecommunications carriers.
        (3) Excryption.--A telecommunications carrier shall not be 
    responsible for decryping, or ensuring the government's ability to 
    decrypt, any communication encrypted by a subscriber or customer, 
    unless the encryption was provided by the carrier and the carrier 
    possesses the information necessary to decrypt the communication.
        (c) Emergency or Exigent Circumstances.--In emergency or exigent 
    circumstances (including those described in sections 2518 (7) or 
    (11)(b) and 3125 of title 18, United States Code, and section 
    1805(e) of title 50 of such Code), a carrier at its discretion may 
    comply with subsection (a)(3) by allowing monitoring at its premises 
    if that is the only means of accomplishing the interception or 
    access.
        (d) Mobile Service Assistance Requirements.--A 
    telecommunications carrier that is a provider of commercial mobile 
    service (as defined in section 332(d) of the Communications Act of 
    1934) offering a feature or service that allows subscribers to 
    redirect, hand off, or assign their wire or electronic 
    communications to another service area or another service provider 
    or to utilize facilities in another service area or of another 
    service provider shall ensure that, when the carrier that had been 
    providing assistance for the interception of wire or electronic 
    communications or access to call-identifying information pursuant to 
    a court order or lawful authorization no longer has access to the 
    content of such communications or call-identifying information 
    within the service area in which interception has been occurring as 
    a result of the subscriber's use of such a feature or service, 
    information is made available to the government (before, during, or 
    immediately after the transfer of such communications) identifying 
    the provider of a wire or electronic communication service that has 
    acquired access to the communications.
    
    Appendix B--Glossary
    
        Communication Interceptions--Regarding a wire or an electronic 
    communication, communication interceptions include any information 
    concerning the substance, purport, or meaning of that communication. 
    Communication interceptions apply to any type of wire or electronic 
    communications (i.e., any transfer of signs, signals, writing, 
    images, sounds, data, or intelligence of any nature).
        Call-Identifying Information--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. (See Pub. L. 103-414, Section 102(2))
        Electronic Surveillance--The statutory-based legal 
    authorization, process and the associated technological capabilities 
    and activities related to communication interceptions and the 
    acquisition of call-identifying information as defined above.
        Law Enforcement--Federal, State, and local law enforcement 
    agencies.
        Pen Register--A device that records or decodes electronic or 
    other impulses that identify the numbers dialed or otherwise 
    transmitted on the telephone line to which such device is attached, 
    but such term does not include any device used by a provider or 
    customer of a wire or electronic communication service for billing, 
    or recording as and incident to billing, for communications service 
    provided by such provider or any device used by a provider or 
    customer of a wire communications service for cost accounting or 
    other like purposes in the ordinary course of its business. (18 
    U.S.C. 3127(3))
        Telecommunications Carrier--Any person or entity engaged in the 
    transmission or switching of wire or electronic communications as a 
    common carrier for hire; including as a person or entity engaged in 
    providing commercial mobile services (as defined in section 322(d) 
    of the Communications Act of 1934) and a person or entity engaged in 
    providing wire or electronic communication switching or transmission 
    service to the extent that the Federal Communications Commission 
    finds that such service is a replacement for a substantial portion 
    of the local telephone exchange service and that it is in the public 
    interest to deem such a person or entity to be a telecommunications 
    carrier for purposes of Title I of the CALEA. The term does not 
    include persons or entities insofar as they are engaged in providing 
    information services and any class or category of telecommunications 
    carriers that the Commission exempts by the rule after consultation 
    with the U.S. Attorney General. (See Pub. L. 103-414, Section 
    102(8))
        Trap and Trace--A device that captures the incoming electronic 
    or other impulses that identify the originating number of an 
    instrument or device from which a wire or electronic communication 
    was transmitted. (18 U.S.C. 3127(4))
