ANSI SCTE 165-13:2019 pdf free download – IPCablecom 1.5 Part 13: Electronic Surveillance Standard
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. One or more Delivery Functions may be utilized to deliver the call content and call-identifying information associated with a particular surveillance order. For example, call content and call-identifying information of a redirected call may not be present at the facilities normally used for surveillance of a subject. It is the responsibility of the PC/TSP to designate a Delivery Function that will deliver call content and call identifying information to a CF for a particular surveillance order. Procurement of the physical facilities connecting this Delivery Function to its Collection Function is the responsibility of the LEA. In most cases, a PC/TSP should be able to intercept calls redirected by a surveillance subject to other locations either in its own network or in the networks of other telecommunications carriers. However, where a subject has redirected incoming calls to a location served by another PC/TSP, the resulting connection may be established without touching the equipment or facilities of the subject’s PC/TSP. Instead, the connections will be made directly from the PC/TSP originating the incoming call to the PC/TSP serving the location to which the subject redirected incoming calls.
When a surveillance subject initiates the placement of an associate on hold for a two-way call, the PC/TSP is not required to deliver call content for the associate to the LEA while the associate is on hold. However, depending on implementation, the PC/TSP might deliver this call content to the LEA. A subject’s call content and call data is transmitted to the LEA over one or more logical channels known as Call Content Connection (CCC) and Call Data Connection (CDC). The actual number of logical channels supported will vary. Factors influencing connection capacity include (1) the number of CCCs and CDCs ordered by the LEA for subjects associated with a given Delivery Function (DF), (2) the number of surveillance orders required to be supported for any single subject, (3) the availability of resources to transport call content and call data information from the DF to the CF, (4) the availability of resources to transport call content and call data information from the IAP to the DF, and (5) the availability of resources to transport redirected call content and call data information between DF’s within the PC/TSP network. Capacity requirements are fundamental to the design and development of any technical standard or specification (as well as for the equipment developed in compliance with such standards). Several technical considerations, pivotal to the design process, are affected by capacity requirements. However, so far, the Attorney General has not identified capacity requirements for telecommunications carriers that use IPCablecom capabilities to provide telecommunications services. In the absence of these formal capacity requirements, certain reasonable assumptions were made in this document about capacity in order to proceed with developing this standard.
