There is a regulatory requirement for all Telecom products to provide a Lawful Interception function to provide a legal mean for authorities to intercept individual devices connected to the network. The European Telecommunications Standards Institute (ETSI) organization has provide standard interfaces to the Lawful functions so systems from different vendors shall be able to communicate over these interfaces without any dependency to different implementations.
The ETSI organization defines an electronic interface for the transmission of intercepted information as part of Lawful Interception. This interface is used from points of interception to LI mediation functions. Typical reference models for LI define an interface between law enforcement agencies (LEAs) and communication service providers (CSPs), called the handover interface. They also define an internal network interface within the CSP domain between administration/mediation functions for lawful interception and network internal functions, which facilitates the interception of communication. This internal network interface typically consists of three sub-interfaces; administration (called X1), transmission of intercept related information (X2) and transmission of content of communication (X3).
For details about different interfaces see the standard ETSI X1 TS 103 221-1 and ETSI X2/X3 TS 103 221-2 documentations from ETSI organization site https://www.etsi.org/
