Currently, interactions between OSs from different suppliers tend to be pairwise and proprietary. This situation leads to higher integration costs and longer times for integration testing. The MTOSI team addresses this basic problem and has already had considerable success in Phase 1 of their work.

The MTOSI is intended to provide the following benefits:

• open OS-OS interface allowing for service providers to more easily “mix-and-match” OSs from different suppliers
• reduced integration times between OSs from different suppliers
• reduced integration costs between OSs from different suppliers
• encourage system integrators to pre-integrate OSs (i.e., before a specific customer requests integration) using a common interface (i.e., MTOSI).

The expectation is that the end customers will be offered services in a timelier manner and at lower costs because of the operational savings.

MTOSI allows service providers to more cheaply integrate OS products from different OS suppliers. System integrators should also benefit from multiple OS suppliers using the same standard interface.

The principle goal of the MTOSI effort is to simplify integration between OSs via an open interface. This leads to lower integration costs and shorter integration times thereby allowing OS suppliers to offer their products to service providers at a lower price and in a more timely manner.

Overview of MTOSI2.0

MTOSI R.2.0 greatly extends the coverage of previous releases to include more management functionality into new areas such as resource trouble and performance management, and service activation and inventory.

The MTOSI Release 2.0 product covers a wide range of management interfaces in support of different functions at the eTOM Resource Management and Operations (RM&O) and Service Management and Operations (SM&O) areas, specifically:

At the RM&O level, the interfaces cover the following domains:

• Resource Inventory
• Resource Provisioning
• Resource Trouble Management
• Resource Performance Management

At the SM&O level, three interfaces are specified in the following domains:

• Service Activation
• Service Component Activation
• Service Inventory

Additionally new transversal aspects have been added:

• Management of connectionless networks
• Inventory updates, multi-event inventory notifications and enhanced inventory retrieval (attribute value matching)
• Enhanced model for resource states
• Multi-action and request transactions

MTOSI R.2.0 also introduces componentized packaging of interface artefacts. The deliverables are packetized into -Document Delivery Packages (DDPs), which contain sets of related Business Agreement (BA), Information Analysis (IA) and Interface Specifications (IIDs) facets. Individual components can be used alone or in combination with other packets, in order to target just the management interfaces that are required for OSS integration.
