Huawei's special maintenance support services include?

Huawei's special maintenance support services refer to optional, value-added services that enhance standard support contracts. "Hardware pre-replacement" (Advance Hardware Replacement), "media retention services," and "major event assurance services" are all classic examples of such optional add-ons. They provide proactive hardware support, data security for failed media, and dedicated support for critical business periods, respectively. Other options mix these special services with standard service components like remote/on-site support or reporting.

A. Remote problem handling: This is a fundamental component of standard maintenance services (like Hi-Care Basic), not typically classified as a special or optional service.
C. On-site services: While scheduled on-site support can be a special service, reactive on-site support is a standard feature of higher-tier maintenance contracts.
D. service support plans and reports: These are standard deliverables included in most maintenance agreements to document service activities and network status.

This document explicitly lists "Advance Hardware Replacement Service," "Media Retention Service," and "Major Event Assurance Service" under the section for "Optional Service Items," distinguishing them from the standard service features.
