Network outsourcing is a multiyear or annuity contract/relationship involving the purchase of ongoing network or telecom management services for managing, enhancing, maintaining and supporting premises or core network infrastructure or enterprise telecommunications assets (including fixed and wireless).
In addition to network or telecommunications management, network outsourcing isolates those services specifically delivered in a longer-term contract in support of network infrastructures: consulting/advisory services, network AD and integration, network infrastructure deployment and support services.
