The platforms support Lawful Intercept (LI) functionality using one of the following solutions: - Centralized PSX solution consisting of an external PSX, a third-party Intercept Server (IS), and EMS
- SBC ERE solution consisting of the ERE, a third-party Intercept Server and EMA
The works in conjunction with the Intercept Server as well as the ERE and EMA (or an external PSX and EMS) to provide call data and call content to law enforcement agencies for calls involving identified intercept subjects. When it receives matching LI criteria in a policy response from the ERE (or PSX), the SBC routes the call as directed and additionally reports call events to the Intercept Server. It also sends media stream (call content) to an IP address provided by the Intercept Server. The supports four types of LI: - Default LI
- IMS LI
- PCSI LI
- PacketCable 2.0 LI

In order to intercept media packets, the EMS must be either the same version or higher version as that of the SBCs and PSXs. |
The following table describes the Call Data Channel (CDC) configuration information required to distinguish between Default LI, IMS LI, and PCSI (P-Com.Session-Info) LI, and PacketCable 2.0 LI. It also lists the types of LI supported on different platforms: Table 1: LI Types and Supported Platforms LI Type | CDC Configuration | Platforms | Routing Policy | LI Interface | Stream Supported |
