Chapter1 Overview of CiscouBR10012 Universal Broadband Router Software
Supported Software Features for the CiscouBR10012 Router
Service Independent Intercept (SII) Support
Cisco CMTS supports the Communications Assistance for Law Enforcement Act (CALEA) for voice
and data. Cisco IOS Release 12.3(13a)BC introduces support for Service Independent Intercept (SII) on
the Cisco uBR10012 CMTS. Cisco SII provides a more robust level of the lawful intercept (LI) options
offered in the Packet Intercept feature. Cisco SII is the next level of support for judicially authorized
electronic intercept, to include dial access, mobile wireless, tunneled traffic, and Resilient Transport
Protocol (RTP) for voice and data traffic on the Cisco CMTS. SII on the Cisco CMTS includes these
functions:
•Packet intercept on specified or unspecified interfaces or ports
•Packet intercept on virtual interface bundles
•Corresponding SNMP MIB enhancements for each of these functions, as intercept requests are
initiated by a mediation device (MD) using SNMPv3
Note For restrictions on this platform, see “Overview of CISCO-TAP-MIB” in Cable Monitor and Intercept
Features for the Cisco CMTS. See Additional Information, page54.
Note No new CLI commands are provided for this feature in Cisco IOS Release 12.3(13a)BC.
Cisco IOS Release 12.3(13a)BC enables full Multiple Service Operator (MSO) compliance with SII and
LI regulations. Service providers worldwide are legally required to allow government agencies to
conduct surveillance on the service provider's traditional telephony equipment. The objective of the SII
feature is to enable service providers with New World networks that legally allow government agencies
to conduct electronic network surveillance.
Lawful Intercept (LI) describes the process and judicial authority by which law enforcement agencies
conduct electronic surveillance of circuit and packet-mode communications. LI is authorized by judicial
or administrative order and implemented for either voice or data traffic on the Cisco CMTS. Table7 lists
the differences between packet intercept and SII features as implemented on the Cisco uBR10012.
