ANSI SCTE 165-13-2019 pdf free odwnload – PCablecom 1.5 Part 13: Electronic Surveillance Standard|
Although CALEA may not apply to any particular cable operator, in general, it requires certain telecommunicationscarriers to ensure that their equipment, facilities, or services have the capability to:
1. Expeditiously isolate and enable the LEA to access reasonably available call identifying information.
2. Expeditiously isolate and enable the LEA to intercept all communications carried by a carrier within a service
area to or from the equipment, facilities or services of a subscriber, concurrently with the communications’transmission.
3. Make intercepted communications and call identifying information available to the LEA in a format available to
the carrier so they may be transmitted over lines or facilities leased or procured by the LEA to a location awayfrom the carrier’s premises.
4. Meet these requirements with a minimum of interference with the subscriber ‘s services and in such a way that
protects the privacy of communications and call identifying information that are not authorized to be
intercepted, and that maintains the confidentiality of the LEA’s wiretaps.
5. TheTelecommunications Industry Association has promulgated a standard [ 19] for lawfully authorized
electronic surveillance for traditional voice telephony.However, the electronic surveillance features and
capabilities for traditional voice telephony provided for in [19] are not readily applicable to telephony providedby means of a cable system, including telephony provided using IPCablecom capabilities.’ This document wasproduced for electronic surveillance specific to telephony services provided by cable operators which are actingas telecommunications carriers and performing their carrier functions using IPCablecom capabilities.
1.4Electronic Surveillance Assumptions
CALEA does not authorize any law enforcement agency or officer to require any specific design of equipment,facilities, services, features, or system configurations, nor does it prohibit the adoption of any equipment, facility,service, or feature by any provider of communication service.
LEAs may be authorized to conduct any of three specific types of surveillance: (1) “pen register,” which recordscall-identifying information for all calls originated by a subject, (2) “trap and trace,” which records call-identifyinginformation for all calls received by a subject, and (3) “interception,” which allows LEAs to listen to the
conversations of the subject, as well as access to call-identifying information. Approximately 90% of all surveillanceorders are of the first two types; Federal law and laws of 42 states only allow the use of the third technique in theinvestigation of serious criminal offenses, and when other techniques have not worked, will not work, or are toodangerous.
As a precondition for a PCTSP’s assistance with Lawfully Authorized Electronic Surveillance, a LEA must serve aPC/TSP with the necessary legal authorization identifying the intercept subject, the communications and informationto be accessed, and service areas where the communications and information can be accessed.2 Once this
authorization is obtained, the PCTSP shall perform the access and delivery for transmission to the LEA ‘s procuredequipment, facilities, or services.
Communications in progress at the time a PC/TSP receives a legally authorized request will not be subject to surveillance. Only communications initiated after the legally authorized request will be subject to surveillance. A PC/TSP shall not be responsible for decrypting, or ensuring the government’s ability to decrypt, any communication encrypted by a subject or associate, unless the encryption was provided by the PC/TSP and the PC/TSP possesses the information necessary to decrypt the communication (18 U.S.C. 2602(b)(3)). Nothing in CALEA would prohibit a carrier from deploying an encryption service for which it does not retain the ability to decrypt communications for law enforcement access. Only packets sent or received by the intercept subject that utilize the capabilities of the Call Management System to establish the communication, and utilize enhanced Quality of Service as authorized by the Call Management System, are considered “calls” as defined by CALEA. Cable operators that have deployed IPCablecom capabilities will offer a range of other services to their customers that make use of packet-switched communications, such as email and Internet access. Other than the packets identified in the first sentence of this paragraph, packets sent or received by the intercept subject are considered Information Services.ANSI SCTE 165-13 pdf download.
