For infrastructure teams that require sustained OS lifecycle support, this three‑year Support Plus offering extends vendor assistance beyond basic updates. The package includes 24x7 phone support for incident reporting, formal problem diagnosis to accelerate fault isolation, and access to the Alcatel‑Lucent Enterprise support portal for case tracking and downloads. Critically, Support Plus covers both software updates and upgrades, enabling planned OS version transitions validated by the vendor. Use this SKU when you need predictable vendor engagement for OS maintenance and want upgrades delivered under the same support contract rather than managing separate upgrade purchases.
