Overview

Prior to SBC 9.0, the SBC Manager of the EMS is dependent on the REST services provided by the EMA. If the EMA is disabled, you cannot configure the SBC from the EMS using the SBC Manager.

To overcome this problem, starting with SBC 9.0, the EMA is segregated into three major components:

Table 1: Independent EMA Components

EMA ComponentFunction
CoreAll of the existing EMA GUI options and functions, except Live Monitor and CDR Viewer options.
TroubleshootingLive Monitoring, CDR Viewer, and the "All" perspective in the SBC main screen.
RESTProvides REST APIs to support SBC Manager in the EMS. When the REST component is disabled, you cannot configure the SBC from the EMS, using the SBC Manager.


Note

If you upgrade the EMA from a pre-9.0 version to 9.0 or higher, all the components are enabled. However, if you upgrade the EMA from 9.0 to higher versions, the state of the components in the upgraded version remains the same as that of the old version.

Note

When you disable the EMA Core/Management and enable the Troubleshooting component, the following restrictions apply to Sign In screens and other user interfaces:

  • For Admin, Operator and Field Service user roles, the Troubleshooting module appears in Classic workspace; the SBC displays the Home/Troubleshooting (excludes Dashboard, but includes Live Monitor), and the All perspective.
  • For user roles such as CALEA and Security Auditor, the SBC displays an error.
