Going No-Code to Launch Services Fast

izzi, one of the largest cable operators in Mexico, was looking into implementing an FTTH network in the residential market while they acquired an FTTH operation. 

They faced multiple challenges. They wanted to launch triple-play services orchestration and activation solution over FTTH in 6 months. They were building a new FTTH network, and the goal was to support residential market activation over fiber. They needed to implement a Service Orchestration and Activation Platform with a new service catalog, infrastructure, orchestration flows, northbound integration, multi-vendor network vendors – from 0 to 100% in 6 months and 100% automated with no manual tasks and zero-touch automation. 

Additionally, they wanted a future-proof no-code cloud-native solution to enable their national digital transformation strategy and manage N-Play services over physical and virtual domains. Their main requirements for the platform were that:

  • It could be deployed seamlessly at a lightning-fast speed.
  • They could rely on it for all the current and future challenges.
  • It would also serve as a convergent platform for legacy and next-generation services.

When the project started, different groups pulled the implementation team in two different directions: Intraway had the IT team eager to integrate the BSS system into the northbound interface for service ordering. On the other hand, the engineering team in charge of the GPON platform wanted Intraway to integrate the resource-facing services’ different components. 

Intraway had to break the dependency between north and south by adding mocked Network Management Systems in Symphonica, the no-code, cloud service orchestration, and activation platform, which allowed them to work in the northbound interface regardless of the readiness of the network. Later, the mocked components were replaced with real ones, an approach that can be used when the deployment needs to be accelerated.

With the incorporation of a new system into izzi’s ecosystem, Intraway encountered the challenge of defining clear boundaries and functions between the different domains. Since day one, Intraway faced the challenge that the language was not typical; it was hard to adapt functionalities from customer’s legacy systems, so Intraway used the TM Forum Application Framework to facilitate conversations.

Using components and entities based in TM Forum, Intraway guaranteed using a common language and simplified the understanding of each component’s scope, domain, and integration.

Symphonica has microservices based on functions aligned with TM Forum (TMF641). The separation of functions allows us to create containers and deploy them in a Kubernetes environment that enables a continuous deployment environment.

For the northbound integration, Symphonica used TM Forum open APIs for critical components such as service orders, service inventory, and service catalog. Intraway shared the API specification number with the customer before the project kickoff. Once they started, the IT department was ready with questions that accelerated the integration process.

The clear separation of functions based on domains was necessary because izzi’s legacy systems had overlaps and boundaries that weren’t clear. With the help of the application framework, it was possible to define new boundaries.

Another vital part of the project was the migration of legacy services. Intraway used business entities for the service inventory based on the information model from TM Forum. Thanks to that, the subset of information needed was well-defined and understood by everyone, which allowed simplifying the migration process and avoiding duplicate information.

izzi also obtained other long-term, key business from the project:

  • Operational Agility & Business Efficiency (Deployment flexibility): New network management systems and network elements can be added in minutes thanks to the design studio that simplifies the southbound connectors’ configuration through multiple protocols.
  • Time-to-Market & Cost Reduction: Symphonica simplifies the development and launch of new services, additional integrations, and mergers or acquisitions. The customer will cut TTM for future implementations of new services in half or more.
  • Reusable integrations & artifacts: Reusable service catalog CFS, connectors, and business orchestration flows. 

Beyond the fiber network expansion that izzi plans in 2021 that will increase FTTH services, izzi will begin to activate DOCSIS 3.1 devices. Symphonica will be part of the architecture in charge of the orchestration and activation of double-play services (data and voice).
