LSO Sonata (BUS:BUS) belongs to the family of LSO Reference Points 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.
