3.1 Definitions

For the purposes of the present document, the following definitions apply:

  • A Network Element Manager (EM) provides a package of end-user functions for management of a set of closely related types of Network Elements. These functions can be divided into two main categories:

– Element Management Functions for management of Network Elements on an individual basis. These are basically the same functions as supported by the corresponding local terminals.

– Sub-Network Management Functions that are related to a network model for a set of Network Elements constituting a clearly defined sub-network, which may include relations between the Network Elements. This model enables additional functions on the sub-network level (typically in the areas of network topology presentation, alarm correlation, service impact analysis and circuit provisioning).

  • A Network Manager (NM) provides a package of end-user functions with the responsibility for the management of a network, mainly as supported by the EM(s) but it may also involve direct access to the Network Elements. All communication with the network is based on open and well-standardised interfaces supporting management of multi-vendor and multi-technology Network Elements.
  • Operations System (OS). This abbreviation indicates a generic management system, independent of its location level within the management hierarchy.
