  • Page 7: Overview

    Introduction 3Com 5000 Routers are intended for use on enterprise-level networks. Depending on the network size, 3Com 5000 Routers can either be core routers on small and medium enterprise networks, or access routers for network branches on some large-sized enterprise networks. Therefore, 3Com 5000 Routers are suitable for the application on the carrier-level networks, such as telecom management networks and billing networks.
  • Page 8 CT1/PRI interface can connect the E1 or T1 interface of switches, as well as communicating with the gatekeeper (GK). With high-speed CPU and digital signal processing (DSP) technology, 3Com 5000 Routers can provide voice over IP (VoIP) services with high quality voice. They can drive down the cost of long distance communications between main office and branches in enterprise deployment.
