Page History

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

To configure the M-SBC LI through the CLI, refer to the following pages:

• Configuring M-SBC for Default LI using CLI
• Configuring M-SBC for IMS LI using CLI
• Configuring M-SBC for PCSI LI using CLI
• Configuring SBC For Lawful Interception

Prerequisites

To configure configure the CDC for cloud an M-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 EMS SWe Standalone Instantiation for Geographical Redundancy (GR) Deployment.
• Create a configurator cluster. For more information, refer to Creating an SBC SWe Configurator Cluster.
• Create a configurator instance. For more information, refer to Instantiating SBC Configurator Using non-DHCP Heat Template.

M-SBC Basic Configuration

To create basic configuration for M-SBC:

Enter a name for the configuration in the Configuration Name field. The SBC configuration name can contain only letters, numbers, dashes (-), apostrophes ('), underscores (_), colons (:) and spaces.

• Ensure that basic M-SBC configuration is completed as in M-SBC Cluster Configuration using SBC Configuration Manager.
• Enable the EMS Calea user. For information, refer to Enabling Lawful Intercept on EMS Standalone
