upgrade and expansion, whole system construction of guideline followed following principles: Advanced: full reference both at home and abroad advanced, and mature of technology, and method and means, Project design, technical product leader, mature products as possible on the main equipment selection, technical lead and aligned with national standards of general-purpose, standard equipment. Systematization: strictly follow the view of system engineering and construction, has always been to practice engineering integrity, hierarchy, and adaptability to the external environment for constructive purposes.
Maximize the business integration, functional integration and avoid different products, different standards and specifications of piecing together and combination of the system. Openness and standardization: hardware device selects the domestic and foreign well-known products, system architecture and protocol standards are in accordance with the ITU-t international industry standards and ISO standards of design, core systems and devices, following international standards, harmonization of standards, ensure system scalability and continuity of the system. Practicality: ensure high availability of the system performance with high reliability and flexibility both; first to ensure stable and reliable operation of the system, and using redundancy design of key components of the key position then to simple, technologically advanced, economical and practical. Extensible and maintainable: within the expected life cycle of systems or equipment, can be upgraded and modified to meet the needs of the user actions and application requirements change. And ensures after-sales service
