For PCSI LI configuration, refer to Configuring the SBC for Lawful Interception as it is supported only on the D-SBC.

 

Configuring the Call Data Channel

To configure PCSI LI:

  • Configuring the Node Number
  • Configuring SBC Core IPsec
  • Configuring CDC with IP Interface Group
  • Configuring CDC for Intercept Flavor as PCSI LI
  • Configuring CDC for Media Interception
  • Configuring CDC for Media Interception over TCP

    • This section outlines how to configure the node number and CDC IP interface group for the PCSI LI.

    Info
    titleNote

    Only the D-SBC (cloud S-SBC and M-SBC) and I-SBC support the PCSI LI configuration.

    For information about configuring the PCSI LI on the S-SBC, M-SBC, or I-SBC, refer to the following pages:

    For information about the PCSI intercept call flow, refer to PCSI Intercept Call Flow.
