Solutions for Fixed Network Operators

Utimaco LIMS enables fixed network operators to comply with national lawful interception requirements for both, voice over circuit-switched networks and for Internet access via broadband or dial-up links.


Internet Access Interception

For the surveillance of Internet access there is generally a choice between active and passive interception methods. With active interception available network elements like routers (typically edge routers) and AAA servers provide capabilities to filter access information and content of the communication of a person under surveillance. Passive methods on the other hand rely on additional filters (probes) that are integrated into the operator’s network to passively intercept all relevant data independent of the commercial services. In some cases a combination of active and passive methods provide the best results or is the only solution feasible.
Utimaco LIMS™ supports a large variety of active and passive interception access points and can be flexibly adapted to individual network configurations and regulatory demands.


PSTN Interception

Voice interception in circuit-switched networks (ISDN, POTS) typically makes use of integrated interception capabilities of the telephone switches. Utimaco has implemented interfaces to voice switches of various leading vendors inclusive Siemens, Nokia, Ericsson, and others.
