What is Element Management System (EMS)?

An EMS is a process to manage network elements (NE) on the NEL or the network element-management layer of a TMN model (Telecommunications Management Network) and it consists of various systems and applications.

In short, NMS and EMS provide a platform that helps in simplifying and managing end-to-end communication networks. They help in monitoring data, as well as managing voice & data communications network equipment of more than one vendor at the same time.

These systems assist in 5 key areas - (FCAPS) – Fault, Configuration, Accounting, Performance, and Security.

NMS and EMS provided by a reliable NMS and EMS Company will cover all these 5 key areas and would offer the following features:

1. Fault Management: This includes alarm generation, event tracking and event analysis.
2. Configuration Management: This includes commissioning, provisioning, timing, and protection of data.
3. Accounting Management: This includes data collection for enforcement of Service Level Agreements (SLAs).
4. Performance Management: This includes monitoring and reporting of service performance, noting Quality of Service (QoS) and management of SLAs.
