Vmux-110 is a customer-located device that complements RAD’s larger modular Vmux-2100 system. It fulfills the need for a low-capacity remote voice trunking gateway for both IP and leased line TDM networks. Vmux-110 is available with a choice of voice channels.

The voice interface includes one of the following:

  • One E1 or T1 port receiving E1 or T1 trunks from PBXs
  • Four or eight FXS/FXO/E&M analog ports that connect to POTS, faxes, or PBX

Vmux-110 compresses the voice traffic and transports it over a serial, a fractional E1/T1, or a 10/100BaseT IP link. The device employs G.723.1, G.729 Annex A and G.711 compression algorithms together with RAD’s unique TDMoIP multiplexing, including transparent CAS and CCS.

The following security protocols are provided by Vmux-110 to ensure client-server communication privacy and correct user authentication:

  • RADIUS (client authentication only)
  • SSH for Secure Shell communication session

Vmux-110 features two 10/100BaseT Ethernet ports, one network and one user. The latter is provided for connecting a user Ethernet LAN to the unit. Together with the Vmux-110 integral Ethernet switch, this allows integrating the user LAN traffic with the compressed voice, over a single uplink (IP, serial, or E1/T1) to the network.

To transfer voice as well as 10/100 Mbps Ethernet data over an uplink with limited bandwidth (such as for satellite applications), the ingress data rate on both Ethernet ports is limited between 128 kbps and 8 Mbps.

Vmux-110 is a compact, 1U-high, half 19-inch wide unit. One or two Vmux-110 units can be mounted in a standard 19-inch rack.
