Adoption of standardized, context-specific processes, APIs and data models can make it easier to achieve interoperability between CSPs. These tools can lower the cost of integration for multiple wholesalers and reduce the complexity for new market entrants by having a readily available service they can adopt. This Catalyst will take advantage of the changes in the latest version of TM Forum’s APIs to create common context-specific processes, data models and APIs for use on different payloads. The first phase of the Catalyst will focus on product and service ordering, addressing, appointing and trouble ticket capabilities, to support interoperability between fiber wholesalers and service providers. While employing TM Forum standards, the project team intends to develop tools that are flexible enough to allow for innovation and differentiation. The goal is to achieve around 80-90% commonality so that companies can have a common set of integration and orchestration services for multiple partners, but still have scope for vendor customization. The Catalyst will develop a set of templates and a sample implementation on the ODA Canvas (an execution environment for open digital architecture components) CSPs can use as a starting point for their own implementations. As well as helping existing players, these technology-agnostic tools will reduce the time and cost to market for new entrants by providing a ready made reference implementation, so they don’t need to start from scratch.
