The HiPath 4000 V3.0 is a highly-resilient IP Convergence platform that combines the benefits of IP networking with the rich features, applications and availability of a circuit-switched system. The HiPath 4000 works in all three types of network environments: circuit, packet and mixed. In a circuit-switched environment you get an IP platform to support valuable circuit-switched capabilities. In an entirely packet-switched environment, you perform cost-effective switching and routing and in a mixed-type environment, you leverage IP when and where your business needs it.
