Delivering T1 Commercial Voice Services with all Class 5 Features over Cable HFC Network

To deliver high-margin T1/E1 voice service over inexpensive Cable HFC infrastructure, rather than traditional TDM networks that may need to be purchased from other carriers.

To support ALL class 5 features, including Centrex, to commercial customers and to deliver these services simply and efficiently using minimum HFC bandwidth

RAD’s Vmux is a scalable, compact product that uses advanced voice compression techniques combined with channel aggregation and multiplexing to achieve a 16:1 compression ratio and a high tolerance to packet loss. It supports fax relay and is transparent to all signaling protocols to ensure that ALL class 5 telephone switch features are supported. The Vmux transmits this integrated voice & data stream across standard IP connections and is compatible with DOCSIS modems. Since the Vmux interfaces with standard T1/E1 ports, it is ideal for providing PBX and Frame Relay connectivity to commercial enterprises and voice services to MDU/MTUs. The Vmux-110 also includes an integrated Ethernet switch with rate limiting capability to ensure QoS in the upstream.
