CTI's network engineering staff applies their systems engineering heritage to solving today's computer network problems. CTI's standard approach to network design can be summarized in four phases: System Requirements; System Design; Project Management, Implementation, and Training; and Maintenance and Ongoing Support.

During this initial phase, CTI engineers determine the business and technical needs that are the driving force behind the design. While performing this analysis, CTI engineers review the existing network infrastructure, operational plans, organizational structure, and strategic objectives to develop a project plan that will provide maximum benefit to the organization.

This project plan is typically defined in terms of system objectives and requirements, system specifications, and implementation overviews sufficient for budget and planning purposes. Critical operating parameters such as quality of service and fault tolerance are identified as part of the design process.

CTI engineers develop a comprehensive network design that fulfills the requirements identified in the first phase. The design process generates a wealth of information including product specifications, project milestones, network diagrams, hardware and software configurations, implementation procedures and timetables, sparing philosophy, and testing plans. This documentation later becomes the critical component for maintaining and troubleshooting the network infrastructure.

After the project details have been developed and reviewed, the project moves to implementation. A team of CTI engineers implements the project according to the developed plan. Concurrently, project management services are provided by CTI to ensure that critical project milestones are met. CTI engineers work closely with key customer staff during this phase to ensure thorough training and a clear understanding of the new network design.

CTI firmly stands behind its design and implementation methods, and can provide support after the implementation has been completed. This additional support may be in the form of on-call, on-site, or remotely managed services depending on the needs of the client. On-site services include CTI engineers to proactively maintain, manage, and troubleshoot network implementations and provide a single point of contact. Contracted on-call services allow the client to maximize their support costs for services and are provided on a 24x7 basis. Remote network management is performed from the CTI network operations center through VPN or direct connection to a network.
