This document defines the interface implementation specification (IIS) for the Multi Technology Network Management catalyst project, shown at the TeleManagement World Catalyst Showcase in Nice (May 2001).  The business scenarios represented in the demonstrated catalyst implementation cover situations where the service provider has purchased equipment from multiple vendors, each providing an Element Management System that manages the subnetworks made up of that equipment (see figure 2.4.1). The vendor employs an NMS to manage multiple vendor-specific subnetworks, creating a network-wide view of resources.  Because Network Elements are increasingly multi-technology, the EMSs may and NMSs clearly do cover multiple technologies. The service provider expects that upper level systems that manage services will be able to integrate with the NMSs to actually create and activate the services and to provide information on network performance and faults.

Providing a single interface between the multi-technology Element Management System/Sub-Network Management Systems and multi-technology Network Management Systems is much more efficient and cost effective than providing individual interfaces for each vendors managed technology. In bringing together ATM, DWDM, and SONET/SDH into one management interface, Multi Technology Network Management fosters this efficiency.

The following companies participated in this project, France Telecom, Telecom Italia, Clear, Marconi, Siemens, Telesoft, Telllium, The NCC Group, and TTI Telecom.
