LONDON -- The TM Forum, is pleased to announce the publication of three deliverables which will facilitate the adoption of an industry wide model for rapidly bring new services to market. The work was led by the Product and Service Assembly Initiative (PSA), a working group within the Forum focused on helping service providers organise their business into an agile factory that can rapidly conceive, create, assemble and launch new products and services far more effectively than they can to date.

The new TM Forum specifications now readily available for download are:

  • A published NGOSS contract specification (TMF 211) which describes the role of an Active Catalog within a PSA type architecture. This document is designed to give Service Providers the ability to request PSA compliant solutions from the vendor community and also to give vendors detailed information on how to comply with such requests.

  • Active Catalog Interface implementation details have been posted on Sourceforge at: This is freely available under an open source license to promote ease of implementation and adoption.

To date, two TM Forum Catalyst Projects have implemented end to end PSA solutions based on this NGOSS contract (TMF211). The implementation experience is captured in the Product and Service Assembly Catalyst Interface Specification ( TMF867). Descriptions of these projects can be found at:, giving Service Providers an early insight into best practice on how to roll out a PSA solution within their operations and potential benefits.

The newly available specifications and project descriptions provide the core information needed for service providers to understand how to undertake their own PSA solutions and provide guidance to vendors and systems integrators. At the same time, suppliers can use the published documents to understand how to provide a complete PSA solution set from business consulting, system integration, and implementation of off the shelf 3rd party compliant products. The PSA group has taken particular effort in providing such a complete set of practical deliverables and interfaces to kick start a complete value chain of PSA suppliers today.

The PSA Initiative comprising of Atos Origin, Axiom Systems, BT, Cable & Wireless, Huawei, Microsoft, Oracle, Qinetiq, TeliaSonera and Tibco has been a working group since October 2006 and the PSA architecture has been met with worldwide industry interest. The group is now in the process of furthering the PSA solution set and building an eco-system of suppliers and early adopters for the new solution set.

The Product and Service Assembly model (PSA) draws its inspiration from other industries, such as the automotive, where the problem of product creation and assembly has long been solved by using the combination of Computer Aided Design (CAD) and Computer Aided Manufacturing (CAM) to drive automated production.

Dave Milham formerly of the BT Group Chief Technology Office and a TMF Distinguished Fellow said, "Increasingly, operators are looking to implement more flexible and cost effective operational platforms to support key business drivers such as the implementation of new IP services and greater operational efficiencies. The PSA is the perfect example of a TMF catalyst project which has became a real working model for telecommunications operations. We hope that it proves useful to service providers trying to solve today´s problems, and some of tomorrows, too."
