LSO Interlude

Frictionless inter-provider commerce.

MEF LSO Interlude APIs

Within the LSO Framework, LSO Interlude APIs address the operational layer of interactions between service providers for delivered MEF standard services, like performance monitoring and fault management. They support end-to-end automation and orchestration of digital services at the LSO Interlude Interface Reference Point in the LSO Reference Architecture.

LSO Interlude APIs combine operational API functionalities with service payloads (data schema). For example, MEF 3.0 Carrier Ethernet services can be orchestrated using LSO Interlude and LSO Allegro APIs for full end-to-end service automation at the operational layer of Carrier Ethernet services across multiple providers within a supply chain.

The related LSO Interlude SDK and standards can be used with a range of MEF-standardized services.

What Can I Achieve with LSO Interlude APIs?

Either standalone, or together with LSO Allegro APIs, LSO Interlude automates digital services end-to-end—from the subscriber through to the service provider and any partner operators.

LSO Interlude APIs support operations automation of a range of MEF services, thus empowering the enterprise with self-service control of digital services.

MEF LSO Interlude API advantages:

  • Enable dynamic service capabilities to off-net subscribers.
  • Support policy-driven control of service attributes.
  • Deliver transparent off-net service performance visibility.
  • Accelerate provisioning cycles.
  • Empower service providers with frictionless self-service control of digital services.
  • Avoid costly, non-scalable proprietary interfaces that may lock the service provider into a wholesale partner.
  • Enable end-to-end service automation across multiple providers.
  • Accelerate problem solving and minimize human intervention in the user experience.
