The company says that as an IP telephone network will depend on a business’s mains power, unlike the traditional telephone system that it replaces, protecting the power supply to give the high degree of availability that will be required of the IP telephone system will be of paramount importance.
Emerson add that this is particularly so where the IP system is to be merged with an existing network that is already protected by UPS if the existing power protection does not provide the extended cover required by the telephone system.
To overcome this problem, Emerson Network Power has developed the Liebert GXT2 range of true on-line UPS for mission critical applications, such as converged data and IP systems, which offers up to 6000VA of backup in tower or in a 2U rack mount form. The GXT2 isolates the equipment it is protecting from power problems, constantly conditioning and regenerating the input power. A wide input voltage window allows UPS support to be provided without calling on the battery, extending system availability. An extended runtime battery option will keep the converged networks live in the event of a long-term total power failure.
