• - Extending E1/T1 voice circuits between distant locations across IP or TDM networks

Many organizations have widespread offices in different locations, both domestic and international. Leasing T1 or E1 lines for interconnecting voice communication between the different sites can be quite expensive. Instead, voice communications can be compressed, packetized and trunked between sites across low-cost IP networks …all without the expense and challenges associated with implementing traditional VoIP solutions. Vmux™-110 and Vmux™-2100 Voice Trunking Gateways employ RAD's innovative packet-based TDM over IP (TDMoIP™) technology to extend voice circuits (including signaling) transparently over IP or TDM networks and therefore eliminate the need for expensive E1/T1 leased lines between enterprise locations.

Voice Trunking over IP

In the application below, each Vmux unit compresses voice channels into IP bundles that are routed to remote locations over an IP network infrastructure in a point-to-multipoint topology. Here the Vmux units eliminate E1/T1 voice circuits between the different enterprise sites, while still retaining all central site PBX features, such as voice mail or caller ID, which are not supported by VoIP.
