Firstly, the PSA has the advantage of being driven by three leading service providers – BT, Cable & Wireless and TeliaSonera – which are collaborating with Atos Origin, Axiom Systems, Celona Technologies, Huawei and Oracle to create a unique IT reference architecture. The service providers’ input is being used to improve the definition of the problem of service assembly and to ensure that the solution will work in the real world.
The PSA reference architecture will enable new services to be easily assembled from existing or new service elements and, in turn, orchestrate the necessary change within appropriate OSS/BSS applications dynamically. The approach is based on a set of co-operating product and service catalogues, and TMF standards are used to provide off-the-shelf integration of the OSS/BSS elements.

into new boundaries of control. The PSA addresses this by encapsulating all three parts into single elements – or beans. Or as the PSA call them: Telco Beans. Beans can theoretically be dispersed across systems or layers, though the PSA describes five principal system areas: Order handling, Product Catalogue, Service Catalogue, Resource Inventory and Devices/network (from the SIP server downwards).
Mikael Åhman, Director of OSS & Production at TeliaSonera, says: "We expect the catalyst project to produce a model that can be

The PSA initiative solves a fundamental problem for service providers. As we all know, every product or service has three elements: data that describes it, rules that it conforms by and process that drives its fulfillment and operation. Of course in traditional telecoms architectures these three elements are fragmented across multiple systems, workflows, integrations and manual processes.

accepted by all our partners, suppliers, developers and operational staff. We anticipate that the Product and Service Assembly catalyst will create a model which is inexpensive to deploy and which limits time-consuming customization.”
If this sounds sufficiently intriguing then don’t take my word for it, come along and take a closer look and see for yourself whether the PSA can deliver against the dream.
