In this section:
The EMS uses the EMS Calea user role for all LI configuration operations and the admin user for communicating over netconf to the SBC. The EMS creates the SBC Calea user credentials automatically when an SBC registers to the EMS. Distributed SBC instances are registered dynamically in the EMS.
A single Call Data Channel (CDC) configuration is supported per cluster.
To configure the M-SBC LI through the CLI, refer to the following pages:
For a D-SBC (S-SBC or M-SBC) cluster, configure the CLI on the OAM node for the cluster.
To configure the CDC for an M-SBC instance:
For LI, CDC configuration is performed using the CDC Configuration Manager through the EMS. You can create CDC information only when logged in as the EMS Calea user from the EMS CDC configuration window.
To configure a cluster CDC for M-SBC nodes:
Click Network > Cluster Management. The Cluster Management / Manage VNFs window opens listing the SBC clusters created on the EMS.
Click the Configurations tab.
Click Cluster CDC. The Lawful Intercept/Cluster CDC window is displayed.
Click Launch CDC Configuration Manager. The SBC Configuration Manager window is displayed.
The SBC SWe provides the ability to configure the IP address, TCP port, and other parameters used for communication towards the mediation server.
The M-SBC supports only one CDC. You will receive an error message if you try to create a CDC when a CDC already exists.
To create a new call data channel:
In the SBC Configuration Manager window of the Calea user, navigate to Configuration > Intercept > Call Data Channel. The Call Data Channel window is displayed.
Select default from the Address Context drop-down menu. You can configure LI using the default Address Context only.
Click New Call Data Channel. The Create New Call Data Channel window is displayed.
To configure the CDC for the default LI, use the following table.
You cannot create or modify mediation servers for an M-SBC with a default LI. Since you cannot create mediation servers, you cannot configure the media TCP or media UDP for a default LI.
For M-SBCs with a default LI, you can configure only the CDC. In the CDC configuration, you provide the IP Address and Port details.
To configure the CDC for the IMS LI, use the following table.
To configure the CDC for the PCSI LI, use the following table.
Click Save.
Click OK.
Click Close at the top-right of the SBC Configuration Manager window.
Return to the EMS session containing the SBC Configuration Manager for the OAM node and click Apply Saved Changes and Close.
When prompted, confirm that you want to save and activate your configuration changes.
After the call data channel is created, you must create mediation server objects associated with the call data channel. The CDC configuration supports up to eight mediation servers.
You cannot create or modify mediation servers for an M-SBC with a default LI.
To create a mediation server object:
In the SBC Configuration Manager window of the Calea user, navigate to Configuration > Intercept > Call Data Channel > Mediation Server. The Mediation Server window is displayed.
Select default from the Address Context drop-down menu.
Select the Call Data Channel you created for the M-SBC from the drop-down menu.
Click New Mediation Server. The Create New Mediation Server window is displayed.
Type a mediation server name in Msname.
Click Save.
Click Ok. The object is created successfully.
You can repeat the preceding steps to create a maximum of eight mediation servers for the M-SBC.
Click Close at the top-right of the SBC Configuration Manager window.
Return to the EMS session containing the SBC Configuration Manager for the OAM node and click Apply Saved Changes and Close.
When prompted, confirm that you want to save and activate your configuration changes.
This screen includes the LI Mediation Server TCP Media intercept parameters.
You cannot configure the media TCP for an M-SBC with a default LI.
The PCSI LI supports configurations only for the media interception (TCP) mediation server.
To view TCP parameters:
In the SBC Configuration Manager window of the Calea user, navigate to Configuration > Intercept > Call Data Channel > Mediation Server > Media.
Click TCP. The TCP window is displayed.
Select default from the Address Context drop-down menu.
Select the Call Data Channel from the drop down menu.
Select the Mediation Server from the drop-down menu. The configuration for the selected server opens.
Use the following table to configure the server parameters. For more information, refer to Media - TCP.
The mediation server parameters can only be updated when its State is Disabled and Mode is Out Of Service.
Enable the mediation server by changing its State to Enabled and Mode to In Service.
Click Ok.
Click Close at the top-right of the SBC Configuration Manager window.
Click Yes to confirm that you want to close the window.
Return to the EMS session containing the SBC Configuration Manager for the OAM node and then click Apply Saved Changes and Close.
When prompted, confirm that you want to save and activate your configuration changes.
You can configure the media UDP only for an M-SBC with an IMS LI.
Use the following procedure to configure the media UDP.
Click UDP.
Select default from the Address Context drop-down menu.
Select the CDC you created for the M-SBC from the Call Data Channel drop-down menu.
Select the mediation server you created for the M-SBC from the Mediation Server drop-down menu.
Use the following table to configure the Edit UDP panel. For descriptions of the parameters in this table, refer to Media - UDP.
You can update the mediation server parameters only when the State is Disabled and Mode is Out Of Service.
Click Save.
Click Close at the top-right of the SBC Configuration Manager window.
Click Yes to confirm that you want to close the window.
Return to the EMS session containing the SBC Configuration Manager for the OAM node and then click Apply Saved Changes and Close.
When prompted, confirm that you want to save and activate your configuration changes.
To view mediation server media statistics:
Click Cluster CDC. The Lawful Intercept/Cluster CDC window is displayed.
Click View Nodes. The nodes list in the cluster is displayed.
Select the node to view the mediation server media status and click Launch Node LI Stats. The Mediation Server Media Status window is displayed.
