The EMS uses the EMS CALEA user role for all LI configuration operations from and to the SBC Configurator; the admin user for communicating over netconf to the SBC. The EMS creates the SBC CALEA user credentials automatically when a SBC (including the SBC Configurator) an SBC registers to the EMS. Cloud SBC instances are registered dynamically in the EMS.

Prerequisites

To configure the Call Data Channel (CDC) for a cloud S-SBC instance:

• Instantiate an EMS SWe instance with LI interface support using the EMS_SA_HEAT_TEMPLATE_VERIZON Heat Templatean appropriate Heat template. For more information, refer to "to EMS Standalone Instantiation for Geographical Redundancy (GR) Deployment" topic in EMS documentation.
• Create a Configurator cluster. For more information, refer to "Creating an SBC SWe Configurator Cluster' in EMS documentation.

• Create a Configurator instance. For more information, refer to Instantiating SBC Configurator using Heat Template.

Configuring CDC using the EMS CALEA User Account

The LI Call Data Channel must be configured on  the the S-SBC to indicate that it supports interception. For LI, the CDC configuration is performed using the CDC Configuration Manager through the EMS. You can Create create CDC information only as EMS calea when logged in as the EMS CALEA user from the EMS CDC configuration window.

Prerequisites

Enable calea user. For information, refer to "Enabling Lawful Intercept on EMS Standalone" topic in EMS documentation.
