The main use for Multi-Technology Operations Systems Interface (MTOSI) is as an interface between Operations Systems. A given product will typically support either the client or server side of an MTOSI interface.
MTOSI provides a unified set of management interfaces in support of these business scenarios, as described in RN306:
- Resource Management & Operations, including
-
Resource Trouble Management: Resource fault management, protection management, and maintenance and diagnostic, allowing communication of alarms between OSs
- Managed Resource Inventory, allowing communication of inventory information between OSs such as Inventory and Discovery OSs
- Resource Provisioning, allows for creating, modifying, and deleting network resources between systems such as Resource Provisioning and Network Management
- Resource Performance Management, covering resource performance monitoring and control, such as threshold crossing alerts from a Resource Performance Management OS to a Service Quality Management OS
- Service Management & Operations, including
- Service Configuration & Activation, including interfaces for Service Activation between a CRM OS and a Service Configuration & Activation OS and between two Service Configuration & Activation OSs
- Manage Service Inventory, supporting bulk inventory retrieval (with filters) between, for example, a Service Activation OS request service inventory from a Service Inventory OS
MTOSI Conformance
A conformance template is to be used by a supplier to indicate their support for various MTOSI interfaces, operations, object, attributes, and notifications, and by service providers to indicate their required support of MTOSI. A spreadsheet (basically a checklist) is provided with each MTOSI release. The MTOSI Conformance Template is part of the TM Forum Procurement program that provides Frameworx-based RFx Templates and Procurement support to simplify adoption of standard interfaces and systems. |
