This blog post will provide a 30K foot view to an Element Management System (EMS) tutorial. An element management system Company can be defined many different ways according to who you talk to. An element management system Company is a part of a communications service provider’s Operations Management Systems. Wikipedia defines it as follows: An element management system Company manages one or more of a specific type of network elements.
Typically, the EMS manages the functions and capabilities within each network element (NE)s but does not manage the traffic between different NEs in the network. To support management of the traffic between itself and other NEs, the EMS communicates upward to higher-level Network Management Systems (NMS) as described in the Telecommunications Management Network (TMN) layered model. The EMS provides the foundation to implement the Telecom Management Network’s (TMN) telecom operations management systems– layered Operations Support System (OSS) architectures that enable service providers to meet customer needs for rapid deployment of new services, as well as meeting stringent Quality Of Service (QoS) requirements. The TMN Model is shown in the diagram below.
NOCVUe’s High Level Element Management System Company Tutorial
At its most basic level, we define it as follows. The Element Management System Company (EMS) provides the functionality to manage and monitor the critical components (Physical & Logical) of the network. On the Northbound, the EMS interfaces with the Network Management Systems Company (NMS) and / or service management systems depending on the deployment scenario. On the Southbound side, the EMS communicated with the devices or the network elements.
The Element Management System’s key functions are basically divided into FIVE (5) key areas called FCAPS: Fault (F), Configuration (C), Accounting (A), Performance (P) and Security (S).
The following table lists down the high-level subset of functionalities supported within each of the FCAPS capabilities.
|Alarm Actions (SMS, Forwarding etc)|
|Accounting||CDR (Call Detail Record) Collection|
|Threshold Crossing Alerts (TCAs)|
|AAA (Authentication, Authorization, Accounting) Services|
*Inventory – Inventory Management, though not listed in the FCAPS functionalities, it basically allows an NOC administrator to maintain up-to-date records about the Count, Type and Status of Devices on the network.
Element management systems Company for some, is a term that is used interchangeably with “device management”. To clarify, Element Management Systems Company, really is the management of multiple network elements (NE) of the same type/same class that are in the same network. The differentiator between device management and element management is, whether the software (which you refer to as Element management) resides on a server outside of your NE or on the NE itself. If it is on the NE then it is called as device management. If it is on a server it referred to as Element management.
