EMA is a Web-Based Interface management system for configuring Sonus Session Border Controllers (SBCs). The Embedded Management Application (EMA) User Guide provides complete set of operational instructions covering all aspects of the EMA Web-Based Interface. EMA enables to rapidly deploy and easily manage Sonus Networks SBCs. As an embedded management system, EMA supports configuration, fault, and security management functions through an intuitive, easy-to-use, browser-based user interface.
The EMA offers feature-rich management framework that supports fault management, configuration and security. It covers all areas vital for the efficient operation, administration, management and provisioning (OAMP) of Sonus SBCs . EMA supports all operations that are available from the SBC Command Line Interface (CLI) and, in addition, provides specialized functionality that is intended to facilitate common device management operations.
If the web browser crashes, hangs or is manually closed while logged into the EMA GUI, the EMA session will still remain open. Manual intervention by the administrator is required to terminate the session from the EMA GUI. To terminate the hanging session, refer to Users and Application Management - User and Session Management page.
This User Guide does not reflect the latest GUI images. The images will be replaced gradually.
This guide is intended for operators and system administrators responsible for provisioning, maintaining, and administering the SBC Core. It is assumed that the end user of this document will have basic understanding and working knowledge of the following technical aspects:
This guide also requires specific knowledge of the SBC and its configuration.
The following are the EMA key characteristics:
The minimum recommended requirements for each user's computer are outlined below. Configurations that do not meet these recommendations may experience excessively poor performance. Also note that slow network connections can also result in poor performance.
The minimum recommended memory/processor requirements of a client computer/workstation when accessing EMA is following:
The platform/browser combinations supported are listed in the table below.
The minimum browser resolution that is supported is 1024 x 768 pixels.

The EMA provides the ability to view status and statistics across contexts. For example, it is possible to view trunk group status across all zones and address contexts. For large configurations, however, performance may be impacted when viewing status and statistics across contexts. This is especially true for configurations with more than 20 zones.
To address this problem, Sonus provides a script to disable cross-context queries. If you experience performance issues when viewing status and statistics, run this script to alleviate this issue.
To disable cross-context queries, perform the following steps:
Enter the following command and press Enter.:
Log out of the redirection console and close it
Log out of the BMC.
To re-enable cross context queries, follow the steps above substituting the following command with the one in step 5:
