Mitel 5000 Network Communications Solutions (formerly Inter-Tel 5000 Network Communications Solutions) enable organizations to blend their voice system into their data network, creating a cost-effective, efficient communications environment. Mitel 5000 solutions offer an IP-centric communications platform, which allows businesses to network geographically dispersed associates and locations, whether they're connecting offices and applications together over a data network, or deploying IP phones to on-site employees. Mitel 5000 solutions support multiple software applications, resulting in operational efficiencies and a foundation for a more flexible infrastructure.
Software has been built on a platform that efficiently combines the best of both data network and TDM (switching) architectures. It provides a complete solution for pure IP deployments. The combination of Ethernet and TDM within the system means that all of the resources needed to deploy a system are built directly into the Mitel CS-5200, CS-5400 and CS-5600 communication servers.
