Vmux-210 Ver. 1.1 Overview 1-1
Chapter 1
Introduction
1.1 Overview
Vmux-210 is a voice trunking gateway that enables several analog voice channels
to be compressed and extended over a serial, E1/T1 or 10/100BaseT 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 an 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.
Vmux-210 can be managed locally via an ASCII terminal or remotely via Telnet or
RADview (RAD’s SNMP-based network management application).
