Chapter 1
Introduction
This chapter provides an overview of the Vmux-210 device and the RADview
Service Center Vmux-210 user interface.
1.1 Overview of the Vmux-210 Device
Vmux-210 is a voice trunking gateway that enables several analog voice channels
to be compressed and extended over a serial, E1/T1 or 10/100Base-T uplink.
Vmux-210 implements G.723.1, G.729 A, G.711 compression and TDMoIP or
AAL2oMPLS multiplexing algorithms to send 12, 15, 24 or 30 analog voice
channels over the IP, E1/T1 or n x 64 kbps network.
Vmux-210 utilizes voice activity detection, silence suppression, echo cancellation
and other techniques to improve voice quality and bandwidth utilization. The
gateway detects, generates and relays DTMF signaling. In addition, Vmux-210
supports fax relay, modem relay and voice band data.
The built-in router supports NAT, firewall, static and dynamic routing, RIP1 and
RIP2. To facilitate the integration of new devices into a DHCP IP network, the
router also supports DHCP client, server and relay.
In this version of RADview, the router function is not supported.
Vmux-210 is managed locally via an ASCII terminal or remotely via Telnet or
RADview (RAD’s SNMP-based network management application).
Interfaces
Vmux-210 includes two Ethernet LAN ports, user and network, and can be
ordered with the following options:
Voice port options:
• 12 FXS ports for up to 12 channels
• 15 FXS ports for up to 15 channels
• 24 FXS ports for up to 24 channels
• 30 FXS ports for up to 30 channels.
