LSO Sonata (BUS:BUS) belongs to the family of LSO Interface Reference Points (IRP) as defined in MEF 55. It defines the management reference point supporting the management and operations interactions (e.g., serviceability, ordering, billing, trouble ticketing, etc.) between two network providers (e.g., Service Provider and Partner Domain). In other words, LSO Sonata supports non-control cross domain interactions between the Service Provider's Business Applications and the Partner's Business Applications. LSO Sonata connects between the BSS functions of the Service Provider domain and the Partner domain respectively and connects 'East-West' in parallel to LSO Interlude. |

MEF is standardizing LSO Sonata APIs as part of a comprehensive effort to standardize multiple sets of LSO APIs enabling service automation across providers and over multiple network technology domains. In the context of LSO, API describes the Management Interface Reference Point along with a data model, the protocol that defines operations on the data and the encoding format used to encode data according to the data model.
